Now that the holidays are over, the decorations are put away and scenes of dreary, wintry weather dance in our heads, one plant with flowers resembling roses that comes into bloom this time of year are camellias. These Asian natives have been cultivated for possibly 5000 years. Most of us are familiar with Camellia sinensis var. sinensis aka, tea! Black tea, white tea, green tea all come from the same plant just processed differently.

Other camellia species were noted and grown for their flowers gracing gardens of temples and nobility. Prized plants were selected and crossed and eventually made their way to England, sometime in the 1730s. These elegant and highly treasured plants soon were spread all over Europe with hybridists and propagators in Italy, France, Belgium, Holland, Portugal, Spain, Germany and the U.K. by the middle of the 19th century. More and more hybrids and cultivars were being developed with the number now well over 3,000. As their popularity grew, camellias were soon being grown in Australia, New Zealand and the U.S. Societies, like the American Camellia Society sprang up and shows were held (and still are) to exhibit various forms and compete for awards.

Options for growing camellias in Connecticut depend on what part of the state you live in. Thanks to breeding efforts of Dr. William Ackerman (retired USDA plant breeder) and Dr Clifford Parks (Univ of NC botanist) varieties of camellias hardy to zone 6 (-10 F) were developed. Depending on the variety and environmental conditions, camellias can bloom from fall to spring. Many of the most popular cold hardy, fall blooming cultivars belong to the Winter Series bred by Ackerman and include plants such as ‘Polar Ice’, Winter Charm’ and ‘Winter Rose’, the latter reaching only 2 to 3 feet high and wide making it a possibility for container culture.

Dr. Parks focused on cold hardy spring bloomers including the April series (C. japonica hybrids). Many grow from 5 to 10 feet tall and can be found at some local nurseries. Look for ‘April Rose’, ‘April Blush’, ‘April Remembered’ and ‘April Tryst’.

Keep in mind that our weather has been somewhat unpredictable so those in zone 6 might want to locate plants in a semi-shaded, protected location. Camellia flowers are just exquisite, resembling roses in colors ranging from white to pink to red. Some are picoteed, some are double and some are very fragrant. The dark green foliage holds up year-round.

Camellias, being broad-leaved evergreen shrubs, have similar requirements to rhododendrons. They do best in an acidic, well-drained soil amended with organic matter. It is often best to group them for effect and also for some protection from the elements. Plants are slow-growing and need adequate moisture but avoid planting them in poorly drained sites. Semi to full shade is preferable as the leaves may scorch in sunny, dry areas. A fertilizer for acid-loving plants can be applied in early spring as directed on the package. Pruning is rarely needed but could be done right after flowering.

I’ve never been fortunate to live in a warm enough location to plant camellias outdoors, but several cultivars are perfect as house plants if kept in a cool spot indoors. Two available from Logee’s in Danielson are ‘High Fragrance’ with delightfully scented light pink semi-double flowers and ‘Scentuous’ with fragrant, semi-double white blossoms. They have others blooming in their greenhouse.

Growing camellias in containers is a splendid way to get winter color, often along with fragrance. According to Logee’s co-owner and horticulturist, Bryron Martin, plants require an acid soil with a pH around 4.8 to 5.8. They can be grown in a camellia/azalea potting mix. Martin advises that young plants can be pinched back for fuller growth although that will delay flowering a bit. Keep in mind that some cultivars can get up to 6 feet in height so either select those that mature at a smaller size or be sure you have space to accommodate them.

Temperature is key to induce blooms. Ideally Martin recommends nighttime temperatures no higher than 59 F during the winter and preferably 30 – 40 F so an unheated room or sun porch is a great place for camellias. If nighttime temperatures are too high, the buds will drop. An east or west exposure will provide adequate light.

Fertilize camellias in the spring when active growth begins. Use a fertilizer for acid loving plants as directed. Commercial synthetic and organic camellia fertilizers are available. Some growers use a cottonseed meal/bloodmeal homemade blend. To supply adequate magnesium to plants, Martin recommends dissolving 1 tablespoon of Epsom salts in a gallon of water and applying this mixture twice a year.

For late fall through spring blossoms, indoors or out, camellias are attractive, evocative plants that perhaps more folks might consider cultivating. Those looking for a Valentine’s Day activity might consider the Camellia Festival at Planting Fields in Oyster Bay, NY. The Lyman estate in Waltham, MA also has a camellia greenhouse that is open to the public.

Plan Early For A Great Growing Season

As you start to plan your next vegetable garden, you may reflect on the previous seasons to help you develop your seed selection, layout, and more. Gardening can already be a sustainable practice, but many want to be more intentional with reducing waste, improving efficiency, and promoting sustainability in their home. Your stages of garden planning should include considerations to ensure you are meeting these goals during the growing season.

The first way to improve your practices is to have an honest assessment of your strengths and weaknesses as a vegetable gardener. For example, through years of trial and error, I have finally admitted out loud that I am not skilled at keeping pepper seedlings warm enough to yield bountiful plants in the growing season. As a solution, I now buy my pepper plants from the garden center in the spring, while still using my setup to start other vegetables and flowers from seed. Using the garden center to help fill in gaps allows you to use that time, energy, and money for seed that has a track record of success. You might even have space to try something new!

Plan to save seed before your plants even start growing. Select seed varieties listed as “open pollinated” so that the offspring will come back true to seed in the following season. Plants that do not have this designation may not come back true to type and may lead to unfamiliar plants in the future!

Consider space as a commodity while you’re planning your garden. Think about the space that some plants require, and determine if that product is worth that space, time, and energy. If your row will yield half a dozen heads of cabbage from weeks of watering, weeding, and care, does that meet your gardening goal? Or do you have other goals in mind? Decisions like this early in the planning stages can help you make your garden more efficient, productive, and tailored to you.

Prevent waste by growing what you and your family will eat. Sometimes gardeners get caught up in the novelty. Purple cauliflower is exciting and worth the space if your family will eat the cauliflower. Avoid overplanting to keep your garden efficient and reduce waste. Does your family get sick of certain produce mid-season? That could be a clue that you're overplanting. When planning for the year ahead, ask yourself if your family has the capacity to eat or safely store whatever is harvested when it is ready. Plant yields are easily researched to help you determine how many plants you may need in your garden to meet your goals.

It can be difficult to consider cutting certain vegetables out of your garden for space or efficiency. However, this is where local agriculture can assist. Just like buying pepper starts from the garden center saves time and energy in the seedling space, buying local produce can help fill any gaps you may feel in your garden’s productivity. From a sustainability standpoint, buying local usually means less energy used in transportation, refrigeration and storage when compared to produce from outside our region.

Cost Share Agriculture (CSA) programs are an effective way to supplement your garden produce. These programs often work on a shareholder system, where purchasing a membership up front will guarantee a share of the farm’s harvest throughout the season usually on a weekly or bi-weekly basis. Connecticut has CSAs for produce, cut flowers, and even meat products. Many of them start signups well before the growing season begins, so keep an eye out! Visiting local farmers markets is another way to help supplement your garden produce, with less of a regular commitment. Some even provide forms of family entertainment, like music, during the summer.

As you plan your next garden, remember that sustainability starts with intentional choices and there is no “one size fits all” strategy. Carefully considering your strengths, weaknesses, and goals will help you promote a sustainable and efficient garden in the season to come.

Five Soil Myths That Cost Home Gardeners Money

Posted on January 4, 2026January 12, 2026 by Zidack, Heather

Every spring, I see the same scene in garden centers. Carts piled high with lime, fertilizer, gypsum, compost-in-a-bag, and something in a shiny package that promises instant results. When I chat with home gardeners, I often ask: How did you decide you needed all of that? Most of the time, the answer is, “I don’t really know. It looked helpful.” As someone who works with soil tests every day, I see the other side of that story. I see the lawn with three times more phosphorus than it needs. The vegetable bed that gets lime every year, even though the pH is already high.

A lot of this comes down to a few myths that are passed down by neighbors, family, and well-meaning advice on the internet. But they quietly drain gardeners’ wallets and sometimes weaken the very plants people are trying to help. Here are five of the most common myths, and what to do instead.

Myth 1: If my plants look okay, I don’t need a soil test.

Plants will try their best in less-than-ideal conditions. By the time plants show clear distress, the problem is often advanced. pH has drifted far from the ideal range. One nutrient is so high that it is starting to interfere with others. In the lab, I see plenty of samples from landscapes that “seem fine,” where the numbers tell a very different story. I also see the opposite. People are convinced their soil is terrible, but the test says they are in good shape and only need minor tweaks.

This myth costs money because skipping the test means guessing. Guessing leads to buying products you do not need and missing the changes that would help the most. A better approach is to test your soil every few years, or sooner if you are starting something new. A good test provides clear recommendations matched to what you are growing.

Myth 2: More fertilizer equals better plants.

People worry they are not fertilizing enough, so “a little extra” feels like good insurance. Extra nutrients do not automatically translate to extra health. Instead, excess fertilizer can burn roots and foliage, push lush but weak growth that attracts pests and disease, and wash into streams and lakes where it fuels algae blooms, harming the environment.

This myth costs money as you are paying for nutrients your plants cannot use. You may also pay later for disease control or to repair damaged turf and stressed garden beds. A better approach is to view soil test recommendations as a ceiling, not a suggestion to exceed.

Myth 3: You should lime your soil every year.

Many people learned that you “always lime the lawn in the fall.” As many native New England soils are naturally acidic, lime can be important in the right amount and in the right places. But I also see plenty of tests where pH is already in the upper 6s or above 7, and the lawn is still getting lime out of habit.

When pH gets too high for the plants, iron and other micronutrients become less available. Acid-loving plants like blueberries and rhododendrons struggle. This myth costs money twice. First, you pay for lime, then you may pay to fix the problems caused by a high pH. A better approach is to test soil pH and apply only when it is recommended.

Myth 4: Adding sand will fix heavy clay soil.

Clay dries slowly in spring, sticks to tools when wet, and can feel like a brick when dry. A bag of sand looks like an easy fix, but mixing a little sand into a lot of clay does not make loam. It often makes something closer to concrete. What truly helps clay is organic matter. Compost and well-rotted manure can loosen heavy soils, improve drainage, and support healthier soil structure and biology.

This myth costs money because you buy sand, haul it around, and see little improvement. For most home gardens, adding organic matter works much better.

Myth 5: Bagged topsoil or garden soil is always an upgrade.

Big bags and bulk deliveries of “topsoil,” “garden soil,” or “planting mix” can feel like a shortcut to perfect beds. Sometimes they are excellent, but at other times they are basically subsoil with a nicer name, which can cause problems like high salt levels, unbalanced nutrients, or a pH far from the target.

This myth costs money because poor-quality material means paying twice. Once to bring it in, and again to correct it. A better approach is to ask suppliers what is in the mix and how it is produced. And whenever possible, improve the soil you already have.

The Common Thread

The common thread in all five myths above is that we reach for products before we understand the soil. If you start with a test, you can skip lime when your pH is already in range, cut back on fertilizer where nutrients are high, and put your time and money into the changes that will actually move the needle. That is better for your plants, your budget, and the rivers and lakes downstream. Your garden does not need every product on the shelf. It just needs the right help at the right time.

Cranberries, A Symbol of Holiday Cheer

Posted on December 27, 2025January 12, 2026 by Zidack, Heather

Each holiday season, a wave of bright red cranberries appears on Instagram feeds, Pinterest boards, and tables across the nation in the form of sauces, desserts, drinks, and decorations. Beyond their seasonal fame however, these tart red berries play a major role in U.S. agriculture and culture.

Let’s start with some numbers. The USDA estimated the 2024 U.S. cranberry harvest at about 8.24 million barrels, roughly 824 million pounds of fruit. Here in the U.S., the cranberry king is Wisconsin, producing nearly 4.9 million barrels, around 60% of the national total. In second place is the historical cranberry producer, Massachusetts, with approximately 2.2 million barrels produced in 2024. The top agricultural crop in the state, Massachusetts’ cranberry crop alone is valued at $73.4 million, supporting over 6,400 jobs and generating $1.7 billion in annual economic activity. Cranberries are so important for Massachusetts, in fact, that they are the state fruit and cranberry red is the state color.

Cranberries, known scientifically as Vaccinium macrocarpon, are native to North America and are a close relative of blueberries. Compared with blueberries however, cranberry plants tend to be smaller, low to the ground and vine-like. The vines require acidic soil (pH 4.0–5.5), a reasonably cool growing season, and abundant fresh water. If these conditions can be emulated at home, cranberries can make an attractive edible ground cover. They perform well when planted alongside plants such as conifers and rhododendron, provided they are given plenty of water and appropriate fertilizer for acid-loving plants.

For commercial production, cranberries thrive in uniquely engineered wetland environments - bogs built atop beds of sand, peat, gravel, and clay. The annual commercial production cycle of cranberries begins with winter flooding, which forms protective ice that shields the vines and prepares the surface for sanding, which stimulates spring growth. As temperatures rise in spring, bogs are drained, and bees pollinate the blossoms. Summer is devoted to irrigation and monitoring, followed by harvest from mid-September through early November, before the cycle repeats with winter flooding and freezing.

Cranberry growers will typically harvest their crop one of two ways: through wet harvesting or dry harvesting. Wet harvesting describes the process where bogs are flooded to allow berries to float to the surface before being netted and loaded into equipment for cleaning and processing. This harvesting technique is the most popular, but requires proper equipment and careful planning. Dry harvesting, the process of using mechanical pickers that comb berries into conveyers, is an approach primarily used for fresh markets. More fruit are left on the vine with this approach, but the collected berries for fresh market can be sold at high prices and dry harvesting allows growers without the means to flood and drain their bogs on a schedule to grow cranberries.

Cranberries are deeply embedded in holiday traditions, thanks to their seasonal harvest, festive red color, and historical use. For more than 12,000 years, they’ve been utilized by Indigenous communities, especially the Wampanoag People, for food, medicine, dye, and winter preservation. The cranberries collected by hand in the bogs of southern Massachusetts were both eaten fresh and dried for shelf stability, then eaten as-is later in the winter or mixed with dried meats and fat to make pemmican, a hearty winter staple.

European settlers in New England quickly adopted the appreciation of cranberries, integrating them into winter celebrations. By the 18th and 19th centuries, cranberry sauces, relishes, and baked goods were staples of Christmas feasts. Their vibrant red hue also made them popular in holiday crafts such as cranberry-popcorn garlands or wreath embellishments.

U.S. cranberries reach peak consumption during the holidays. Though 95% of cranberries are processed into juice, sauce, or dried fruit, fresh cranberries remain a holiday staple, used in everything from stuffing and pies to cocktails and décor. Around 400 million pounds are eaten annually, with an estimated 20% consumed during Thanksgiving week, about 80 million pounds. With per-capita annual consumption averaging 2.3 pounds, mostly in juice or processed form, cranberries rank second among berries consumed in the U.S. after strawberries!

Cranberries exemplify a convergence of historical tradition and the advances of modern agricultural practices. They support regional economies, sustain traditional farming techniques, and bring seasonal joy to millions. As you gather with loved ones this holiday season, enjoy an extra serving of these tart crimson berries and remember that food isn’t just sustenance, it’s heritage, celebration, and connection.

Gifts for the Gardener on Your List

Posted on December 20, 2025December 23, 2025 by Zidack, Heather

If you have a gardener in your life, last minute holiday shopping can be tough. Each year, we provide a list of suggestions that might help you as you’re shopping. For 2025, we are considering gardener comfort and adaptability.

Gardening Gloves

While it seems like a trivial gift and your gardener may already have a good pair, gardening gloves are a great gift! It’s always nice to have an extra pair in case your hands get wet working in muddy soil, or if you manage to lose them. Our gloves wear over time, and can thin, stretch, and decline in quality as seasons change. While any pair may be helpful as a backup pair, you might get bonus points for finding your gardener’s favorite brand or style. These are readily available in hardware stores or year-round garden centers.

UV Protective Clothing

With the improvement of UV protective textiles, gardeners can find them in all sorts of forms. UV shirts, gloves/sleeves, and even hats are available to help your gardener stay protected from the sun. This is great for anyone who loves being outdoors, but especially those who may have extra sensitivities to sunlight. While not a direct substitute for sunscreen, they can help provide a little extra protection. I find that these often are best found online, though I have seen individual items at independent garden centers, sporting stores, and gift shops throughout the state.

Cooling Towels

Athletic cooling towels are meant to help keep you cool. Soak them in cool water, wring out the excess and wear as a scarf or drape over your shoulders. The evaporative cooling from the towel helps you stay cool even during the warmest summer days. While they’re usually found with the sports gear, your gardener will love them, too!

Waterproof Shoes

Nobody likes wet feet, especially in the garden. Help the gardener you love stay dry by gifting them with a pair of waterproof shoes! These come in many forms such as rubber rain boots, rubber clogs, or even waterproof sneakers. They can be found at sporting goods stores, shoe stores, or online.

Shop Smart

There are many gifts beyond these recommendations that may suit the gardener in your life. As we approach the last-minute shopping season, keep these tips in mind to help you find the perfect gift.

Look carefully at the label of any seed mixes, seed bombs, or other plantable gifts, especially if you are intending to gift native seeds. Many of these mixes sold across the country may provide plants native to North America, but not necessarily native to our region. The label provides a percentage breakdown of every species of seed included. Cross reference to ensure that they are native to our region.

Purchase durable tools and equipment over novelty items. Give your gardener gifts that they will be able to use for years to come. While gloves with claws to help you dig are fun and unique, a good trowel will stay part of your gardener’s arsenal for many years.

Consider your gardener’s interests to help guide your gifting. If your loved one plants more flowers than vegetables, a garden hod might not be the right fit for them. If they hate weeding, a gift to make the chore easier might be a great fit! Think about the ways the person you’re gifting likes to spend time in their garden and tailor your gift to them.

Don’t rule out experiential gifts just because it’s winter. Gardeners who wish to continue to learn and spend time with like-minded green thumbs may enjoy a workshop, class, or conference. Many regional garden shows (including the CT Flower & Garden Show) take place during the winter. Local garden clubs, libraries, or garden centers may also offer educational workshops that you could purchase tickets for in advance.

Shop smart. While we can’t recommend any brands or specific places to shop, use your smart consumer skills when looking for these or any other gifts this season. Reading reviews, using trusted retailers, and balancing quality with price will help you verify that these gifts will impress.

If you’re shopping last minute for that gardener in your life, remember that it doesn’t have to be stressful! Keep comfort, adaptability, and their unique interests in mind for a gift that’s sure to please!

Seasons Greetings

Posted on December 13, 2025December 18, 2025 by Zidack, Heather

It is hard to believe it is that magical time of year again. Thoughts turn to how we are going to celebrate the holidays. This would, of course, include decorating our living spaces. Fortunately for plant people, there are no shortage of choices for the season. Plants also make wonderful gifts to take to a holiday gathering. After all, they bring nothing but joy and cheer.

Red, pink, and cream poinsettias with solid and variegated leaves arranged together. — Poinsettias come in some amazing colors. Shown here are solid red and pink as well as two-toned combinations of colors (photo by M. Lisy).

The first holiday plant that comes to mind is the poinsettia. Although native to Mexico, they seem to have found their way into every corner of the country. It is not actually flowers that are the stars of the show, but the colored leaves. What was once a beautiful red has been selectively bred for some absolutely amazing colors. My all-time favorites include a newer snow-white colored one, yellow, and the orange varieties. If two-tone leaves are preferred, there are neat red with pink centers and white with pink centers – both of which look absolutely stunning. A new one for this year has snow white leaves with a slight pink blush at the center. Of course it does not end there! There are varieties like “Jingle Bells” which looks like the red has white paint splattered all over it, which makes it a real conversation piece. The “Christmas rose” comes in many colors now and has the leaves swirled into a rose shape.

The poinsettias are beautiful, but they take a little bit of TLC to get them to stay that way. They should only be watered when they are dry to the touch on the surface. Let them dry too long, and they drop leaves. Cold drafts will produce the same result. If water is splashed on the leaves, the spots will discolor and dry, ruining the look. These plants are best watered from the bottom by filling the tray they are sitting in with water and letting the soil and roots wick it up. Poinsettias tend to fall from grace after the holiday season, and therefore are treated as a temporary decoration.

There are a number of other plants that will make just as nice of a display. The first is the Christmas cactus. They bloom profusely this time of year. They also make a great houseplant if they are allowed to dry out between waterings. To get them to rebloom the following year, put them in a room that is only illuminated by natural light – mother nature will take care of the rest (they need a critical period of darkness to flower). These plants can be so long lived that they can become family heirlooms.

Some lesser-known plants include the frosty fern, which is not a fern at all, but a Selaginella (Spikemoss). Although some species can tolerate extreme desiccation, the species sold during the December holiday season cannot. These are great for people who love to over water because if they dry out at all, they will wither and die. They actually prefer to be in moist, soggy soil but not submerged. Cyclamen are nice looking plants with the flowers held above the leaves. These are somewhat long lasting, but tend to go dormant. They seem to be hard for most people to keep long term. Kalanchoe plants have beautiful flowers of all different colors, but these are also a challenge to keep as a long-term houseplant. Amaryllis bulbs can be beautiful when blooming, and after a dormant season may rebloom the following year. These are easy to keep provided the watering is done only while growing and not while dormant or dying back.

I do not know if it is the marketing or the colors of holiday plants that make them so popular, but do not forget about traditional houseplants for gifts. Some nice philodendrons, spider plants, pothos, or snake plants certainly make wonderful additions to any home. There are so many beautiful new varieties coming to the market all the time. No matter what plant species is chosen, plants tend to put a smile on the face of the receiver. In my opinion, there is no greater gift. If the choices are too many, then why not get a gift certificate for a local independently owned nursery or greenhouse? Happy holidays!!!

Barn Cupolas And What They Do

Posted on December 6, 2025December 8, 2025 by Zidack, Heather

Cupolas are small structures built over a hole in the roof centerline to provide light, ventilation, a nice view or perhaps some decoration to the overall structure. While found on many kinds of buildings including the International Space Station, the main purpose of barn cupolas is functional over form. With the advent of tighter barn construction to keep livestock warm during the winter, moisture buildup became a problem. The cupola became a necessary addition to barns to help reduce this moisture buildup and to allow fresh air to enter the barn.

While used in the Middle East and eventually in Europe, these structures were more decorative than functional. They were eventually used less as domes became more popular. In the United States, cupolas were introduced in the late 1700s by settlers from Europe and used as barns increased in size and allowed for more hay storage and livestock housing. Tighter construction by means of siding and better roofing became the norm in the mid 1860s, and this resulted in ventilation issues as moisture levels increased.

The larger amounts of hay could build up heat and occasionally spontaneous combustion occurs if fresh air is not provided. Both the hay and the barn could be destroyed. Tighter barns also meant more moisture from both the breathing of the cows and from a constant deposit of urine and manure. Fresh air and the removal of moisture was needed for the health of livestock and to prevent mold developing on and ruining stored hay.

The solution was a nifty piece of architecture called a cupola. Farmers started installing cupolas as a means to draw out hot, moist air and stale gases from manure via louvered slats on all four sides. Fresh air could also enter while rain and snow were mostly kept from entering the roof as these louvers were downward facing. The health of livestock kept in close quarters in cold weather improved, and mold development on stored hay was reduced through this ventilation. Additionally, livestock kept warmer in the cold months required less food, so hay lasted longer and in good condition.

The spacing, size, and number of cupolas needed depended upon the linear footage of roof centerlines. The number of livestock and amount of hay storage were also considered. This is why some barns have many of these structures, while other barns may only have one or two. Barns with open sides have no need for cupolas.

While the primary function of cupolas has been to provide ventilation for haylofts and livestock areas, there are many styles of cupolas that also incorporate various decorative designs. On Hanks Hill Road in Mansfield, there are two barns on two different properties near each other that have the exact same unique design, which is rather fancy while still being functional. I suspect the same person designed and built both as they are almost identical in decorative woodwork and unusual peaked roof lines. I have not found other cupolas with such intricate woodwork and wonderful design features.

Historic barns often have fixed or awning windows that either don’t open or that are hinged on the top or bottom and open only slightly. Some cupolas are topped with a weathervane or a finial. Farmers took great pride in their barns. They could be a large investment, so it’s understandable that many put elaborate cupolas on their barns to make a statement about their pride and prosperity. As you drive around farm country, perhaps now you will notice some interesting cupolas that have been there all along.

Highlighting Connecticut’s Winter Cheer: Common Witch Hazel

Posted on November 29, 2025December 2, 2025 by Zidack, Heather

Connecticut’s native species of Witch Hazel, Hamamelis virginiana, is a remarkably unique woody ornamental that can be found as a large shrub or small tree. It comes to the rescue this time of year as the leaves continue to drop and our surroundings become starved of color. Its foliage in autumn is a showstopping yellow.

Hamamelis virginiana can grow between 10 and 20 feet tall and is often nearly just as wide as it is tall. In ideal conditions, some can even grow as large as 30 feet tall. It has a loose and somewhat open, irregular rounded shape and is very attractive in landscaping when used as hedge rows, woodland edge planting, or along a pond or river. It’s the last plant to come into bloom each year in the Northeast, blooming from October to December. The bloom coincides with its flashy fall foliage, making it one of the most eye-catching specimens of the winter landscape.

The blooms are bright yellow with spidery, ribbon-like petals and have a pleasant citrusy fragrance. They are clustered tightly around the branches, and the petals curl up protectively during cold spells. A few cut branches in a vase will be sure to perfume and brighten up your home during the dreary winter months. Its late flowers attract certain species of flies, bees, gnats, and cold-tolerant moths. These insects are a food source for native songbirds such as kinglets, chickadees, and titmice.

The medicinal qualities of the Common Witch Hazel are world renowned and have been utilized for centuries. Its anti-inflammatory properties serve as a soothing remedy for bruises, itches, sunburns, acne, and small wounds. In fact, Common Witch Hazel extract is one of the only medicinal plants approved by the FDA as a nonprescription drug. Always consult with a medical professional before incorporating the use of medicinal plants. It's worth noting that there have been several Witch Hazel processing plants in Connecticut, starting in the 19^th Century. To this day, most of the world’s Witch Hazel extracts are still produced in East Hampton, Connecticut.

Consider planting a Common Witch Hazel or two in your yard, mixed with hollies, viburnums, and dogwoods for some late-season cheer. Common Witch Hazel will grow in a variety of conditions, from moist to dry, and shaded to sunny. Flowers are most abundant when planted in full sun. It prefers acidic, nutrient-rich, well-draining soil. It’s quite hardy, growing in zones 4 through 8, and has very little trouble with pests or diseases. After establishment, they are virtually care-free. The only maintenance of note is periodic pruning to remove suckers if a controlled shape is desired.

Although it is a slow growing plant, it is worth the wait when it bursts into bloom. With so much going for it, this is a plant that deserves greater consideration for use in ornamental landscapes and yards.

Road Salt and Your Soil

Posted on November 23, 2025November 25, 2025 by Zidack, Heather

When I was a graduate student from Nepal living in New Haven from 2012 to 2014, I kept noticing the same winter aftereffect across town. Along busy streets, the first foot of lawn by the pavement turned yellow and matted, and the road-facing sides of yews and hollies burned while the yard sides looked fine. Coming from a place that does not spread salt each winter, it felt backward. We made the road safer, but the plants and soil paid the price. At UConn’s Soil Nutrient Analysis Lab, we hear versions of this every spring. People send soil from a strip along the road or from a bed near the driveway and say that spot never greens up like the rest.

You have also likely noticed the symptoms. Fine particles form a crust on the soil surface where water evaporates. Turf browns right at the pavement edge. Buds on the roadside of a shrub fail to break. Evergreens brown on the street side when traffic spray carries salty water, while the interior needles stay green. Vegetable beds that sit too close to plow piles can exhibit poor emergence, tip burn, or slow growth, even when the rest of the garden appears fine.

What road salt does to soil

Sodium chloride (rock salt) is the most widely used deicer. Once it dissolves, it separates into sodium (Na⁺) and chloride (Cl⁻). Chloride is highly mobile. It moves with meltwater, so in a wet spring, it can leach through the soil and, where conditions allow, reach groundwater, affecting well water quality.

Sodium changes how soil behaves. In healthy soil, calcium and magnesium sit on exchange sites; repeated sodium inputs displace them, sealing the surface, reducing infiltration, and making the soil feel tighter right where plants already struggle. Sodium also competes with potassium uptake, so salt-burned spots can look nutrient-deficient even when tests show adequate levels.

Alternatives to sodium chloride are often less harsh but cost more. Magnesium chloride and calcium chloride melt at lower temperatures but still add chloride and can injure plants and corrode concrete and metal. Calcium magnesium acetate (CMA) is chloride-free and generally gentler, yet it’s pricier and harder to find.

Lab testing and management options

If you inform the lab that the sample is from a salt-affected area (such as a roadside, plow pile, or splash zone), they will interpret the numbers with that history in mind and, if necessary, use the appropriate salinity method for your sample.

Soil pH and texture (and organic matter). Sandy roadside fill flushes salts quickly but is more susceptible to damage due to its low buffering capacity. Heavier soils with more organic matter hold up better but can crust at the surface after repeated salting. For optimal plant health and reduced salt uptake, aim for a pH of approximately 6.5–7.0; your report will include a lime rate if your pH is below this range.
Soluble salts / electrical conductivity (EC). EC shows how salty the root zone was when you sampled. It is most informative right after winter or snowmelt, when salts are near the surface. For mineral soils, labs typically measure EC from a simple soil–water extract.

Start with prevention. Before winter, top-dress the first 1–2 feet along the road with a thin layer of compost to improve structure and exchange capacity. Keep that strip covered, overseed thin turf, or use a salt-tolerant edge, and ask the plow operator to place piles where meltwater drains to the street or to vegetation that isn’t over your well line. Where meltwater goes matters as much as how much salt you use.

After winter, fix what the season left behind. If the roadside sample shows elevated EC, lightly loosen any compacted or crusted soil so that water can infiltrate. Then, leach the area with two or three deep soakings a few days apart to push salts below the main root zone. If a hedge or shrub burns on the roadside year after year, consider moving it back or replacing the front row with more salt-tolerant plants.

For chronic hotspots, shift from one-time flushing to long-term protection: use less deicer, keep piles away from beds and wells, maintain dense groundcover in the first foot along pavement, and in harsh exposures, consider stone mulch plus seasonal compost topdressing to help the soil rebound.

If your well water tastes salty, check the state’s road-salt guidance and contact your town. When the damage is limited to curb strips or driveway beds, soil testing and better winter practices usually solve it.

Winterize your Garden Gear Before It’s Too Late!

It’s already November! It doesn’t seem like that long ago when we were giving advice about seeding lawns and watering in new fall plantings. Now that the time has changed, the days feel shorter, and the nights are getting colder, it’s important to remember to take the time to properly store your garden equipment and accessories before locking up the shed for the season.

Freezing temperatures are on the way fast. Drain and roll up any hoses to remove tripping hazards from the landscape. Store them inside a garage or shed to keep them out of the elements and lengthen their lifespan of use in the garden. Make sure that your outdoor water systems are properly winterized. Whether that means flushing your irrigation system, or simply shutting off your outside water, don’t forget this important step to protect your pipes! Once lines are turned off, open external valves to relieve any remaining pressure.

Water can not only wreak havoc on pipes but many garden accessories, too. A glass rain gauge left outside can and will freeze and shatter outdoors. Ceramics like pottery and bird baths are susceptible to cracking, so store them either in the shed or upside down in a sheltered area. Stash your garden gnomes, garden flags and solar pathway lights to protect them from fading and damage. Brittle cold, freezing water, and a careless throw of the snow shovel could spell disaster for garden décor left out in the open.

Inside the shed, take a quick inventory. Leftover seed or bagged mulch could be rodent attractants. Seeds should be stored in areas safe from extreme temperatures to preserve germination rates. Bird seed should be stored in animal proof containers. Chemical products like pesticides and fertilizers may be adversely affected by temperature fluctuations and freezing. They could also make a real mess if a water-based or pressurized solution were to burst. Products leftover from the growing season should be evaluated and moved into a space safe from freezing temperatures. Product labels or manufacturers will have storage and disposal information to help you make the best decision about what to do with your garden chemicals at the end of the season.

Winter will be a great time to thoroughly clean, repair, and sharpen tools. Store them somewhere that is easy to get to later so you can make sure your tools are fresh for the new season! If you have to do the seasonal shed shuffle, this is also a great time to rotate the lawn mower and snow thrower to prepare for the first storms of the season.

Speaking of your gas-powered equipment, check your owner’s manuals for winterizing recommendations and instructions to help maintain the life and quality of your equipment. You may need specific maintenance before long term storage. Contact a professional for any maintenance tasks that you do not feel confident performing on your own.

If you’re running out of space in the shed and garage, consider covering lawn furniture with UV and mildew resistant covers. Take down awning covers and temporary structures. I, myself, have fallen victim to the false sense of security of a mild winter, only to be devastated by the collapse of my garden tent in the first, albeit belated, heavy snow.

While all of this seems like common sense, the mad dash from here to the holidays will have many of us pulled in different directions. Our equipment, tools, and garden infrastructure are some of the biggest investments we put into our gardens. Hopefully this short checklist will help you knock out those last few chores that come with maintaining a four season New England garden.
