Chaos gardening is a growing social media trend that encourages gardeners to relinquish control, scatter assorted seeds, step back, and see what happens. Instead of carefully spacing plants and planning layouts, chaos gardeners toss seeds and let nature decide what grows where. The results can vary widely, ranging from a surprising assortment of plants to a patch of disappointment. 

Unlike traditional gardening, this approach emphasizes spontaneity over structure. For many, the appeal lies in its simplicity. Chaos gardening is easy to start, requires minimal knowledge, and often relies on leftover or inexpensive seed packets. The low-stakes, experimental nature makes it especially attractive to busy people or those new to gardening. 

Still, the trend raises valid questions. Without site preparation or ongoing care, how well can seeds establish? And does “letting go” invite weeds into the garden under the guise of wildscaping? 

In practice, chaos gardening often produces mixed results. While the concept is appealingly simple, success rates can be low, and plantings may struggle to persist long term. Still, gardeners interested in the trend can improve their chances of success by following a few simple suggestions. 

Avoid using this approach in large or prominent spaces. Start small, either in a container or a less visible area of the yard. To maintain a sense of experimentation, while increasing success, consider focusing on a single species at a time or scattering spring bulbs through an existing lawn. Tossing out a packet of “wildflower” seeds may sound charming, but it will not produce an instant, picture-perfect meadow. More often, it results in a steadfast patch of mugwort.  

Even with a relaxed approach, a bit of planning goes a long way. Key factors such as sunlight and soil conditions still matter. The principle of “right plant, right place” applies regardless of gardening style. Identifying site conditions, selecting appropriate species, and preparing the planting bed can significantly improve outcomes. 

Gardeners should also approach seed mixes labeled “wildflower,” “pollinator-friendly,” or “native” with some caution. While not inherently problematic, these mixes can contain species that are poorly suited to local conditions. A quick review of the species on the list can help inform decisions about whether the plants are suited to the region or growing conditions. 

Learning how to recognize seedlings, including common weeds and invasive plants, is another important step. Early identification allows gardeners to remove undesirable species before they establish. Observing which plants succeed can also guide future efforts, gradually transforming a disorderly patch into a more reliable and productive space. 

Patience is essential. Many perennials grown from seed take more than one season to flower. Including a mix of annuals and perennials can help maintain visual interest while longer-lived plants establish. As with any gardening method, some trial and error is expected. 

Chaos gardening may never replace traditional approaches, but it offers an accessible entry point for beginners and a creative outlet for experienced growers. With a balance of spontaneity and informed decision-making, even an unstructured planting can become a living experiment.

What to Know Before You Buy Topsoil

By Dr. Avishesh Neupane, UConn Soil Analysis Lab

The word topsoil suggests rich, dark earth that will fix most of what ails a yard. Maybe the lawn never recovered after construction, a new raised bed needs filling, or a bare patch by the driveway still looks more like gravel than garden. Buying a load of topsoil seems like a simple answer to all three. 

But "topsoil" is not a guarantee of quality. Depending on the source, it may be dense, low in organic matter, full of stones, or simply a poor match for the job you have in mind. That means homeowners should buy it with a clear idea of what it can and cannot do. 

The first question is not what to buy, but what problem you are trying to solve. If the real issue is low pH, low fertility, or some other imbalance, another load of soil may not help much. A soil test is an inexpensive way to check pH and nutrient levels before you start adding products. 

If you are filling a new raised bed, topsoil alone is usually not the best answer. A blend of topsoil and finished compost works better than straight compost or straight mineral soil, because the two materials do different jobs. Topsoil provides mineral content, structure, and weight. Compost adds organic matter, holds moisture, and improves tilth. Most unamended topsoil is low in organic matter, which is why a topsoil-compost blend is usually more useful for gardens and landscapes. 

There is no state-run topsoil grading or certification system in Connecticut, so buyers have to ask a few questions on their own. Where did the soil come from? Has it been screened? Is it meant for lawn repair, general grading, or a vegetable garden? Is compost already mixed in, and if so, how much? These answers matter because soil products are not interchangeable: material sold for grading can be fine for filling low spots but a poor choice for a vegetable bed. 

It is also worth thinking about what might come along for the ride. Poorly sourced soil can carry contaminants that are not obvious to the eye, including residues from past land use. Ask the supplier about the soil's origin, and if there is reason for concern, have it tested for lead or pesticide residues before planting. If the product includes compost, ask whether it comes from a reputable testing program, such as the U.S. Composting Council's Seal of Testing Assurance, which requires routine testing for heavy metals and pathogens. There is a biological concern as well. Invasive jumping worms and their cocoons can hitch a ride in soil, compost, mulch, and potted plants, so buying from reputable sources and using heat-treated compost or mulch when possible can help reduce that risk. 

Texture is another simple check. If the material feels sticky and heavy when wet, it may seal up and drain poorly. If it feels very light, peaty, or woody, it may settle quickly after a season or two. Good garden soil, or a good topsoil-compost blend, should crumble easily, drain reasonably well, and still hold moisture. It should smell earthy, not sour or strongly ammonia-like. 

Cost deserves a clear-eyed look as well. Bulk soil is usually cheaper than bagged soil and creates less plastic waste, but the cheapest load may not be the best buy if it leaves you with hard, low-organic-matter material that won't support plant growth well. 

There is one more caution, mainly for gardeners who refresh beds every year. Building organic matter in a tired soil is a good idea, but more compost and manure are not always better over the long run. Repeated heavy additions, especially of manure-based compost, can push phosphorus levels well above what plants can use. That is a problem for water quality if the soil erodes, and it can throw off the balance of other nutrients. A periodic soil test is the best way to know whether a bed actually needs more material. 

For most homeowners, the best results come from matching the material to the job. Test first if you can. Use topsoil for structure and volume, compost for organic matter, and each where it makes sense. For a raised bed, start with a soil-compost blend. To repair a lawn after construction, plan to build organic matter over time with compost, mulch, and returning grass clippings or shredded leaves to the soil. When buying from a bulk supplier, ask questions before the truck shows up. 

Topsoil can be a useful tool, but it is still only one ingredient. Better soil is built, not delivered in a single truckload.

Solitary Wasps Found in the Landscape and Garden

By Pamm Cooper, UConn Home Garden Education Office 

Solitary wasps are primarily hunting wasps which are either digger wasps or thread-waisted wasps. Most are seldom aggressive toward people because they are not defending a social colony. Instead, females are busy hunting other insects or arthropods to stock cells for a single larva to feed upon as they develop. Many solitary wasps dig nesting chambers in sandy soils, like the cicada killer and the great golden digger wasps. Others may use hollow pipes, tubes, window ledges or even sliding door tracks (a favorite site for the grass-carrying wasp). 

Many of these wasps are also considered decent pollinators. They are active from June through late summer. The adult wasps die during the year and larvae generally pupate and emerge the following year. Females hunt specific prey such as caterpillars, katydids, cicadas and other insects which they paralyze and stock the nesting chamber with. An egg is laid on or near these future meals, and the larva will feed on them as it develops.  

The great golden digger wasp, Sphex icheneumoneus, is a  large wasp that sports golden hairs on the head and thorax and has a distinctive half orange half black abdomen.  It is harmless to people and is often found on flowers in or near sandy soils where it digs nests for larvae in the ground. Main prey for larvae is katydids.

The Eastern Cicada killer, Sphecius speciosus, is one of the largest wasps in North America. It has amber wings and females are most evident in late July and early August as they burrow into sandy soils, leaving behind a squared off entrance and a sandy mound. Deep inside underground, the females have dragged paralyzed cicadas upon which they lay an egg. The larva will hatch and eat the paralyzed cicada. Next summer, after having pupated underground, the adults emerge. The females rarely sting but do alarm many homeowners due to their size and activity in lawns and along sidewalks.

Grass carrying wasps Isodontia spp. create cells from grasses collected by the female. Each cell is stocked with paralyzed tree crickets, katydids and other orthoptera insects. Often packed together, these nesting cells can be found on windowsills, on bases of slider doors and on upper window ledges. Larvae overwinter in these cells and emerge as adults the following year or later that same year if there are two generations. 

The oak apple gall wasp Amphibolips spp female lays an egg inside the tissue of an oak leaf inside which the larvae will hatch. The apple-like gall forms as a response to secretions from the larvae as it feeds on the leaf tissue safely inside. The gall turns brown after the adult wasp emerges. No damage is done to the oak. Cutting open the gall when green will reveal the wasp larva in the center. 

 

Potter Wasp, Eumenes fraternus, females construct a small, rounded clay structure with a neck-like protuberance with a flattened top that makes it look like a tiny pot. After laying a single egg inside the female puts some paralyzed caterpillars and beetle larvae which the larva will eat. She seals the small opening with mud, which will be chewed open when the adult emerges next year. These tiny pots can be found on plants, rocks, pieces of wood and other places. 

Solitary wasps pose little risk to us as they go about completing their life’s work. Defending nests is not a behavior such as is done by social wasps and hornets. Females will sting if handled or alarmed though, so avoid doing that. If digger wasps make you nervous, consider amending sandy soil with organic matter and keeping it moist when females are looking to excavate nesting chambers. Try to tolerate them for the short period of time they are active. Almost all can be found obtaining nectar from flowers in the wild and in cultivated landscapes.

A Familiar Bloom in a Season of Change

By Emily Leahy, UConn Plant Diagnostic Lab

Spring is the ultimate bringer of change. The restless souls contained within all forms of life begin to awaken, bringing fiery hues back to the formerly dreary expanse of winter landscapes. We meet this shift with a warm welcome, grateful for a chance to start anew. Innately, we crave change, constantly striving towards something greater that will fill a part of ourselves we feel is missing. Also, innately, we are walking juxtapositions. Above our desire for change floats an asterisk, denoting an extraneous condition—our deep fear of the very thing which we wish so desperately for. New experiences bring about uncertainty and inconsistency.  Thus, we cling to that which we find familiar and trustworthy to ground us while careening through the unknown.  

For me, ol’ reliable is the lilac shrub in my backyard. Season after season, I look out my window and am reassured by its presence, whether it is flush with vibrant blooms or displaying its tall barren branches. The leaf and flower buds of common lilac (Syringa vulgaris) are among the first whispers of spring I observe, appearing early in the season.  

Members of the olive family, Oleaceae, lilacs are well suited to life in cold climates—in fact, the chill of winter is essential to their bud development and maturation. Although new plantings take a few years to adjust and establish themselves, these perennial shrubs are equipped with substantial longevity. Common lilacs can live for up to a century, cementing their place as a companion to rely on during every phase of our lives.  

Common lilacs grow rapidly and immodestly, filling their landscape with a dominating sense of confidence. Success is dependent on being planted in sunny locations with moist, well-drained, and neutral to slightly alkaline pH soils.  

The lilac’s blooms are dichotomous, both quietly delicate and also boisterous with a showstopping flair. Flowers emerge between late April and early May. A strong, sweet fragrance diffuses from the quaint petals which cluster together in formations called panicles. Lilac blooms appear in a variety of hues, ranging from lavender to blush pink or even a creamy white.  

Even after the flowers of lilacs retire, matte heart-shaped leaves remain until the fall, painting the tall shrubs with dark green. During the dormancy of winter, gray stems and branches are visible, standing tall and proud even when cold weather casts its icy shadow over the once vibrant landscape.  

Lilacs are relatively self-sufficient yet require some care and attention to maintain their vigor. Susceptible to fungal diseases like powdery mildew and septoria/pseudocercospora leaf spot, it is important to ensure proper airflow throughout plantings to discourage sporulation. Powdery mildew is characterized by gray mycelial growth on leaf surfaces, while septoria/pseudocercospora leaf spot appears as brown spots that expand into broad patches. Insect pests, namely the lilac borer and oystershell scale, also impose their will on lilacs. Borers tunnel and weave through branches, leaving holes and open wounds as evidence of their travels. Oystershell scale refers to small insects, resembling their namesake in appearance, that take refuge on lilac bark. These pests and diseases can commonly be managed through removal and destruction of damaged tissue. In severe cases, additional integrated pest management strategies may be necessary. 

Consistent pruning practices are essential for lilacs to remain healthy throughout every season of change. Lilacs are beings of extreme preparation, developing next year’s buds as soon as the current flowering period is complete. By deadheading blooms promptly after they have run their course, lilacs are able to dedicate more energy to generating healthy flowers for future growing seasons. Renewal pruning is another beneficial technique—cutting back overgrown stems to remove barriers preventing light from reaching inner branches. This encourages new growth and results in lilacs which appear fuller, bursting with color from the inside out. Spring is the most appropriate time to employ these pruning tactics in accordance with lilac’s growing needs. Prune immediately after flowers start to fade for best results. 

Lilacs are a cornerstone of spring, providing a familiar and reassuring sight to ground us when our own lives become unrecognizable. Lilacs and the endless wonders of spring gently remove the asterisk from our desire for change, reminding us to take solace in the familiar while welcoming all that the unknown may bring.

Keep Your Seedlings Going Strong! 

By Heather Zidack, UConn Home Garden Education Office 

So, you started your seeds, have been watching them attentively, and spring is knocking at the door. It’s still a little too early to put some things outside, but overzealous gardeners may find themselves swimming in seedlings that need management. Consider taking these steps to help you and your seedlings find a comfortable compromise as they wait to go outdoors. 

If you haven’t done so already, thinning your seedlings is an important step in ensuring that the plants you put in the ground will be robust and strong. As a fellow gardener, I’m familiar with the pain of disposing of “perfectly good seedlings.” However, this isn’t an entirely true belief. Seedlings that are not thriving in optimum conditions, may be indicating to you that they aren’t strong for planting in the garden.  

Thinning prevents crowding and allows for more air flow between seedlings. When crowded, seedlings compete for water, nutrition, light, and space. By thinning, we ensure that plants have enough resources to grow healthy. Thinning also helps to encourage airflow, which can reduce the risk of fungal development. Fungal pathogens can lead to issues like “damping off,” and other plant diseases that put your seedlings at risk.   

You may decide to thin your plants by snipping out weaker seedlings at the base. If you have the heart, the patience and the amount of valuable bench space to dedicate to extra seedling trays or containers, you may decide to carefully tease apart seedlings and replant them for one last chance.

Your strongest seedlings should be potted up into a larger container to encourage them to continue to grow. Putting seedlings into 3- or 4-inch pots (or recycled plastic cups with holes in the bottom) gives them a little bit extra wiggle room while we wait out these temperature fluctuations of a New England spring. Extra space for the root zone will allow the plants to continue to expand. More roots mean more water and nutrient uptake, leading to healthy growth. This practice may also help reduce watering needs on your part, since there is more media to hold moisture in the root zone.  

Are your tomato seedlings getting leggy? You can bury the stems of the tomato seedlings to help promote adventitious root development. Remove the cotyledons and any small leaves that you intend to bury below the soil line. Make sure to leave at least one third of the plant’s total height above the soil line to continue healthy growth. 

To this point, our seedlings have grown in optimum conditions, or as close to optimum as we’ve been able to provide. Not only have these conditions been ideal, they’ve also been consistent. When your plants get out to the garden, the new environment may be shocking. Hardening off is a process of transitioning them from their ideal growing conditions, into a more realistic environment. Any plant, whether it is a new seedling, a beloved houseplant, or a sheltered patio tropical, needs this transition when moving from inside to outside.  

Take your plants on “field trips” during warm spring days by placing them outside in a location with bright, indirect light. Full sun may be too strong for seedlings that have been acclimating with grow lights or through sunny windows so introduce direct light incrementally.  

Using cold frames can help to transition your plants from indoors to outdoors. These small, unheated enclosures use the sun’s energy to store heat like a greenhouse. This helps to reduce the drastic temperature swing of nightfall and insulate plants from frosts during the temperamental spring season. Crack them open during warm days for ventilation and to help start reducing humidity.  

When conditions are right for hardening off and planting your seedlings, continue to monitor weather conditions. Late spring in New England has been known to throw us a cold snap or two. If frost/freeze warnings occur, bring in potted plants and use a frost cover or breathable fabric to cover in-ground plants as frost protection. Garden stakes will help keep fabric from directly touching your plants and help create a warm air pocket around them to survive those incidental cold nights. 

Spring in New England is a season of transition. Warm days may signal planting time, but cool nights and shifting conditions remind us to move forward carefully. By thinning crowded seedlings, giving roots room to grow, and easing plants gradually into outdoor conditions, gardeners can help reduce stress and build resilience. A little patience and flexibility now can pay off with healthier transplants, stronger growth, and a more successful garden as the season continues to unfold.

Starting Raised Beds

By Dr. Lauren Kurtz, UConn Home Garden Education Office 

There are many styles of raised beds to choose from, depending on your needs. Raised beds exist on a spectrum, ranging from framed boxes above ground to unframed, elevated planting mounds. When planning new raised beds, both types have specific considerations to keep in mind. 

Mounded Raised Beds 

Mounded raised beds are created by mounding existing soil or adding additional material so the planting area sits above ground level. This method works well on compacted sites, in poorly drained areas, or on top of heavy clay soils. 

Most mounded raised beds do not have a barrier between the ground and the mound. However, if you are wish to start a raised bed over lawn, cardboard can be placed underneath the mounded soil to smother the grass. If you use cardboard, it is best to allow it to decompose for a few months before planting. This will allow plant roots to grow freely into the soil below rather than being blocked by the cardboard layer. 

The bed can be built using soil already on site, by mounding soil from the paths or edges into the bed. Alternatively, you can bring in topsoil and compost to create the beds. Any imported soil or compost should be free of pathogens, contaminants, and invasive weeds. Mounded raised beds are not tilled, and walking on the mound will compact the soil, so foot traffic should be avoided. These beds may need to be reshaped or re-mounded annually. Soil tests can be taken every two to three years, then apply amendments added as needed.  

Framed Raised Beds

Framed raised beds offer many of the same benefits as mounded beds, along with additional structure and accessibility. A framed raised bed is more contained than an in-ground bed and can be made of wood, metal, or pavers. These beds are well suited for compacted or poorly drained sites, locations with contaminated soil, or in gardens designed to improve accessibility for people with limited mobility. 

Raised bed depth can vary depending on the intended use. Some beds are only a few inches deep, while others may be up to 2 feet. Gardeners who use wheelchairs or who have difficulty bending may want to consider an elevated or deeper bed. Most annual vegetables require 12 to 18 inches of soil depth, root vegetables will require greater depth. Length and width can also vary based on site conditions, but a width of about an arm’s length is generally recommended for easy planting, harvesting, and weeding.  

Prefabricated wood or metal beds can be purchased, or you can build your own using lumber. Cedar is often preferred over pine because it lasts longer, although it is more expensive. Use caution when considering repurposed or pressure-treated wood. Before 2004, pressure-treated lumber was treated with copper, chromium, and arsenic, which could leach into the soil. If pressure-treated wood is used, make sure it is labeled for ground contact. Whenever possible, choose untreated or naturally rot-resistant materials. 

A good soil mix for framed raised beds is about one-half to two-thirds topsoil and one-third to one-half aged compost. This can require a large amount of material and may be costly depending on the size of the bed. Buying bulk topsoil by the cubic yard is usually less expensive than purchasing bags of raised bed mix. For smaller beds, bagged raised bed mix may be more practical. Avoid using free fill or topsoil from unfamiliar sources, as these may contain contaminants, invasive weeds, or invasive jumping worms. 

To save money on filling a raised bed, some gardeners use hügelkultur, a method that fills the lower portion of the bed with logs, sticks, leaves, grass clippings, or kitchen scraps before adding topsoil and compost on top. Larger materials are placed in the bottom then followed by smaller organic materials overtop. Over time, the bulky material breaks down and enriches the soil. Because the material settles as it decomposes, additional topsoil and compost may need to be added annually. 

Plant Choice 

Annual plants are generally better suited to raised beds than perennials or shrubs. Extreme temperature fluctuations in raised beds are not ideal for overwintering perennials, and the need to periodically add more soil makes raised beds better suited to annual crops. 

Care and Maintenance of Raised Beds 

Both mounded and framed raised beds dry out faster than in-ground gardens, so supplemental irrigation is usually needed throughout the growing season. Weed pressure may be minimal, but regular weeding will still be necessary. Raised beds should be mulched to help retain moisture and reduce weeds. 

The paths between raised beds can be planted in turf, covered with wood chips, topped with crushed gravel, or left as bare ground. Keep in mind that paths between mounded beds may need to be mowed or weeded regularly. They will also likely become compacted over time due to foot traffic.

Look Before You Leap Before Buying Fruit Trees

By Pamm Cooper, UConn Home Garden Education Office

Garden centers and other retail stores have fruit trees for sale now, and in some instances, the price is too good to pass up. But before you run out and buy fruit trees, there are some things you need to consider before purchasing. First and foremost, consider whether you will need more than one tree, or variety of tree, to ensure good cross-pollination.  

Peaches, tart cherry, and apricots are self-fruitful and do not need another variety in order to pollinate well. A single tree will produce fruit if all environmental conditions are adequate. But most sweet cherries and pears will not produce much fruit unless the proper cross-pollinator variety is nearby. For example, if you want Bartlett pears, then you will also need another pear variety- d’Anjou, Bosc, or Comice- to ensure proper pollination and good fruit yield.  

Providing a cross-pollinator with apples is especially tricky. They are self-unfruitful and require another variety of apple whose flowering period overlaps with it to ensure optimum pollination of the flowers. Pollinator requirements are often not well- understood by novice gardeners who are planning to grow apples for the first time. Many people make the mistake of only buying the apple trees they want for fruit, such as MacIntosh, and they do not realize they will need one more variety of the correct cross-pollinator to get fruit of an acceptable amount.

Apples belong to one of three groups- early, mid, and late-season -blooming. So early and mid-season blooming varieties will provide adequate cross-pollination and fruit set with each other, while mid and late-season varieties will do the same. A late blooming variety then will not provide cross-pollination with an early blooming variety. Conversely, an early blooming variety will not help a late- blooming variety cross-pollinate. The mid-season flowering varieties can be effective cross-pollinators of both the early and late-season varieties.  

Note: if there are flowering crabapples nearby that flower at the same time as the apple variety you have, then cross-pollination can be sufficient. Crabapple flowers attract diverse bees and other pollinators. If you already have an ornamental crabapple that flowers when your apple tree does, that will likely be sufficient to ensure good pollination of your apple tree. Apple varieties like Jonathan, Jonagold, Golden Delicious, Gal and several are listed a self-fruitful, but they will set more fruit if cross-pollinated.  

To simplify a gardener’s efforts to get the best cross-pollinators for their fruit trees, there are charts available that can be printed and brought to the garden center or nursery that will help in fruit tree selection. If you find a fruit tree variety you really like, do a little research before buying it see whether another variety will be needed for cross-pollination or not.  For a good fact sheet that explains the ins and outs of fruit tree pollination there is valuable information on the following link:

I hope we have a great fruit growing year here in Connecticut. May the pollinators and good weather be with us.

Hold Off for Healthier Soil: Managing Spring Compaction Risks 

By Nora Doonan, Soil Science Graduate Student, UConn Department of Plant Science & Landscape Architecture

In the case of soil compaction, the early bird often does not get the worm. As temperatures rise, many Connecticut residents are eager to get back into their gardens and begin lawn care. However, after a winter marked by significant snowfall, the effects of snowmelt are still present in the form of pooling water and high soil moisture. Although the warmer weather may seem like the perfect time to begin spring yard work, it is often best to wait. Working or walking on wet soil can lead to compaction, a soil condition that can negatively impact plant health throughout the growing season. Wet soils are more easily compacted than dry soils, and once compacted, they are much harder to remediate.  

Soil compaction restricts root growth, making it difficult for plants to access water, nutrients, and oxygen. As a result, plants may show reduced growth and lower yields. Compacted soils also limit water infiltration, which can lead to increased runoff during spring precipitation events. This not only reduces water availability for plants but can also contribute to soil erosion and water pollution, particularly in areas located near streams, ponds, and other water bodies.  

Soil microorganisms are impacted by compaction, some of which are responsible for soil nutrient cycling. For example, compaction reduces pore space, which holds oxygen and a lack of oxygen in the soil can increase the rate in which some bacteria perform denitrification, a gaseous loss of nitrogen to the atmosphere. Other soil organisms are impacted as well. Non-burrowing animals, such as mites and springtails, have difficulty penetrating compacted soil, and there is often a decline in burrowing species like earthworms, ants, and beetles.  

Common causes of soil compaction include heavy foot traffic and the use of equipment such as lawn mowers, spreaders, and vehicles. Following the same consistent pathway through your yard and garden, even if it seems insignificant, can lead to substantial compaction overtime, especially in high soil moisture conditions. Homeowners should also be cautious about allowing heavy vehicles, such as mulch delivery trucks or off-street parking, onto lawns when soils are wet. Additionally, tilling wet soil can do more harm than good by creating dense soil layers and deep ruts. It is important to wait until soils have dried sufficiently before working them. 

To assess whether soil is compacted, start with a visual inspection. Areas with poor plant growth, shallow roots, or standing water after rainfall may indicate compaction. Simple field tests can provide further insight. One method is to dig into the soil with a shovel or spade a few days after a rainstorm. Signs of compaction include surface crusting, plate-like soil structure (resembling stacked dinner plates), or large, dense clods. Another method is to perform a soil hardness test. A few days after rain, try pushing a wire flag or similar probing object into the soil. Hold the flag at the top and press the wire into the soil without bending it. This test is most accurate when soils are moist but not saturated, and care should be taken to avoid rocks. If the probe penetrates less than 4 inches, the soil is considered compacted.  

Preventing soil compaction is far easier than correcting it. Avoid walking on garden beds and refrain from working soils when they are wet. Use lighter equipment whenever possible and maintain ground cover to protect the soil surface. If necessary, aerate compacted soils and incorporate compost or organic matter to encourage biological activity from soil organisms that naturally improve soil structure. While organic residues such as compost can help cushion the effects of compaction, excessive traffic will degrade these materials over time. Soils with low organic matter are especially vulnerable to compaction, making regular amendment essential. 

Patience in early spring can pay off throughout the growing season. Waiting until soils are drier before beginning yard work will help protect soil structure, promote healthy plant growth, and support long-term landscape sustainability.

I “Heart” Philodendrons

By Dr. Matthew Lisy, UConn Adjunct Faculty

Back in the late1970s when I stumbled upon my mother’s abandoned houseplant book, I had no idea what impact that would have on my life.  It was a treasure-trove of knowledge for me, and came with a gallery of some of the most common houseplants.  One in particular caught my eye – the Heartleaf Philodendron.  I was immediately in love (see what I did there?).  All jokes aside, this was one of the biggest staples of the houseplant world, and it still is.  Characterized by green heart-shaped leaves, they were commonly displayed in macramé plant hangers.   

 These plants, like many of our houseplants, come from humid tropical Central and South American forests.  The word Philodendron comes from the Greek and means “tree lover.”  This name serves as both the scientific and the common name.  As one would expect, plants in this genus grow on trees in some fashion.  Of course there are exceptions, but most will readily grow up moss poles if provided.  A number of the species are perfectly suited to life in a hanging basket, and are commonly referred to as “trailing” to describe their growth habit.  A few of my favorite trailing-types are the ones I will focus on for this article.  Trailing Philodendrons are one of the easiest plants to grow and also the easiest plants to kill.  The secret to their success is to not over water them.  The top inch or two of the soil should dry out before they are watered again.  They are very unforgiving to overwatering, and quickly develop a fungal infection that will fist cause many leaves to drop, and then the vines will wither and die.  Many people see this and assume the plant needs more water, and then accidentally ensure the plant’s death.  If they are put outside for the summer, I recommend hanging them under a covered porch so the watering is controlled.  

The old-school Heartleaf Philodendron was just the beginning.  It is known as Philodendron hederaceum by scientists.  It may be incorrectly labeled as Philodendron cordatum, but this is an older/inaccurate name and beyond the scope of this article.  One modern favorite variety is called Lemon Lime.  As expected, it has some light green to yellow leaves in bright light.  Next to the regular green, this variety really stands out.  Lemon Lime is similar to one I had thirty years ago called Lemon which had only yellow leaves.  There is another new one called Neon that has all yellow leaves as well.  It is hard to know if these are true varieties or repackaged versions of the old Lemon with newer names.  Brazil is another very hardy variety that has green leaves with a large, thick yellow stripe down the center of each leaf.  There is variability in the amount of yellow in each leaf, which adds further interest to the plant.  A similar but more striking variety is called Silver Stripe.  This plant has a thinner stripe down the middle that is mostly cream or silver colored.  This was extremely expensive last year, but is much more common and therefore cheaper now.   

 There are a number of different species with similar appearance and growth habits to our P. hederaceum.  One of the real stand-outs is the Philodendron brandtianum, commonly referred to as the Silver Leaf Philodendron or Philodendron Brandi.  The leaves are a gorgeous true silver color with green stripes following the veins.  These are slower growing than the others mentioned here.  By the end of last year, it was somewhat affordable in four-inch pots.  I have yet to see it offered in a larger hanging basket (probably a few years away from that).  A close look-a-like to this plant is the Philodendron sodiroi, which is also called the Silver Leaf Philodendron.  Though less intensely silver and with paler green coloration, the leaves are larger.  I finally saw one for sale last summer but passed on it as I think it was a mislabeled P. brandtianum.  Nevertheless, I am sure these will be equally popular with collectors.

All of these plants are easy to propagate by cutting the stem and leaving one leaf per node.  Dip it in rooting hormone and keep it in a moist, clear-bag-covered pot and in a few months, there will be new growth.  Alternatively, they can be rooting in water, but I prefer the soil method as it doesn’t have to adapt from water to soil when transplanted. 

 I am hopeful that this article will rekindle an old flame with the Heartleaf Philodendron or its relatives.  They are all generally available now in many of the big box, online, and brick-and-mortar plant stores.  Why not pick one up to beautify the home for many years to come?

The Carbon Sink Under Your Feet: Why Your Lawn Matters

By Dr. Avishesh Neupane, UConn Soil Nutrient Analysis Lab

When we think of climate solutions in Connecticut, our minds usually go to big things such as offshore wind, public transit, and forests. We rarely think about our lawns. But soil science suggests that the roughly 40 to 50 million acres of lawn and managed turfgrass in the United States represent a large and often-overlooked opportunity to help keep carbon dioxide out of the atmosphere, especially when those landscapes are well managed. Although forests store far more carbon overall in wood and soil, lawns can still play a supporting role by storing carbon mostly belowground, as long as maintenance inputs like fertilizer, mowing fuel, and irrigation are kept in check. In other words, done well lawns can store carbon in soil; done poorly, those same inputs can wipe out the gains and even make a lawn a net source of emissions. 

Your lawn and garden are not just aesthetic choices. They are living systems. Through photosynthesis, grass and other plants pull carbon dioxide from the atmosphere and turn it into sugars. Those sugars are basically “carbon packages” the plant uses to grow. Some of that carbon ends up in leaves, stems, and flowers, and some is sent belowground to build roots and feed soil microorganisms. 

As roots and microorganisms grow, die back, and regrow, they add carbon-rich material to the soil. That material becomes part of the soil’s organic matter. In the Northeast, well-managed turfgrass can store carbon at meaningful rates, with published estimates often ranging from a few hundred to more than a thousand pounds of carbon per acre per year. 

That same organic matter also gives soil what many gardeners call the “sponge” effect. It helps the ground absorb water, hold moisture longer, and maintain better structure. That means less runoff during storms, better drought tolerance during dry periods, and a healthier root zone overall. Healthier, carbon-rich soil helps a lawn do more than stay green. It helps the landscape better withstand weather stress and keeps more water and nutrients where they belong. 

Management that Protects Soil Health 

The benefits of a lawn or garden depend heavily on how it is managed. Poor soil management can weaken plant growth, reduce biological activity, and limit the soil’s ability to store carbon over time. If we want the lawn to store more carbon and withstand weather extremes better, management matters. We can start with the following practical steps. 

First, test your soil and apply only what the test calls for. Guesswork often leads to over-application of fertilizer, especially phosphorus and nitrogen. Excess phosphorus wastes money, can upset nutrient balance, and increases the risk of runoff into local waterways, where it can contribute to algae overgrowth. Excess nitrogen is also a concern because it can be lost to the air as greenhouse gases and to water through leaching and runoff, affecting groundwater and streams. A soil test helps you target nutrients and lime where they are actually needed, supporting healthier roots and the soil biology that helps build carbon-rich soil over time. 

Second, address compaction. When soil is compressed by repeated foot traffic or heavy equipment, it loses pore space. That limits air movement, reduces water infiltration, restricts root growth, and weakens biological activity. Carbon storage does not stop altogether, but the soil becomes less effective at building and holding additional organic matter. In lawns, core aeration can help relieve compaction. 

Third, keep the soil covered. Dense grass cover and recycled clippings help shield the soil, reduce erosion, buffer moisture swings, and support soil life. This also supports soil carbon by keeping roots growing and by reducing the loss of carbon-rich soil through erosion and rapid drying. The key is to maintain healthy turf and avoid practices that leave bare ground for long periods. 

A Landscape of Stewardship 

For Connecticut lawns, the real test is not just how green they look in a good week. It is how well they hold up through heavy rain, summer dry spells, and changing weather patterns. That resilience starts in the soil. 

A healthy, carbon-rich soil is one of the best ways to make a lawn more resilient. By focusing on plant-appropriate pH, good soil structure, and science-based nutrient management, we do more than improve how a landscape looks. We make it better able to absorb water, support plant growth, and store more carbon over time. 

Your lawn will not solve climate change on its own. But better soil management can make it healthier, more resilient, and modestly better at storing carbon. That is a practical win for landowners, for water quality, and for the broader environment.
