“A late summer garden has a tranquility found no other time of the year.”
— William F. Longgood
Overwhelmed by Weeds?
This season's pattern of lots of rain and lots of heat have made it difficult for gardeners to get out into their gardens, while creating the perfect environment for weeds to thrive!
We've been getting quite a few calls regarding weed management and invasive species control as gardens are booming with unwelcome guests. And while there is no one[size-fits-all approach to weed management, here are the key points to remember:
- “Nature abhors a vacuum." Leaving bare soil or undisturbed garden areas will more likely lead to the development of weeds. Instead, keep the soil covered until you intend to plant. Encourage dense plantings of cover crops in vegetable gardens, utilize groundcovers, or consider using mulch of a thickness of 3" or more for walkways and desired plant-free areas.
- Minimize the seed bank. Keep weeds mowed or cut back before flowers or fruit emerge. Turn the soil, or ensure dense plantings don't allow seeds to germinate by shading out the area or preventing good soil contact. Consider pre-emergents if you have a history of recurrence.
- Sometimes (not always) weeds can be an indication of soil fertility. Therefore, soil amendments may be more effective than spraying or hand pulling. Get your soil tested to know for sure!
- If considering garden chemicals, always make sure to identify the weed and use only products that are labeled for that plant. Read the label in full for all information regarding application rates, safety and environmental considerations.
- Be patient and persistent with management. Total eradication and control may eed multiple seasons before you see results. Keep at it!

Renovate Your Strawberry Beds
To promote continuous success of strawberries in your garden, take time this August to perform renovations to your plants. Maintenance such as clipping tall growth, removing weak or dead leaves, and fertilization will help to maximize the productivity of your strawberries in the coming years. Mulching, ensuring adequate water intake, and weeding are also necessary for upkeep of strong plants. These techniques maximize yields and protect against disease prevalence.

Where are the butterflies?
UConn Home & Garden Education Center
Are you seeing fewer butterflies in your garden? You're not alone.
New studies have determined that over the past two decades in the continental United States, the populations of hundreds of butterfly species have fallen by 22%. These declines are commonly attributed to pesticide use, habitat loss, and climate change. This is concerning because butterflies play important roles in pollination, cycling nutrients, and are a significant food source for other organisms such as birds.
However, conservation biologists have created a roadmap for recovering butterfly populations across the US, and their best chance at recovery starts in your backyard. Actions you can take include providing as much habitat as possible for these animals and keeping these areas pesticide-free.

Native Plant: August Flowering Perennials
Native spotted Joe-pye Weed (Eupatorium maculatum), Boneset (Eupatorium perfoliatum) and certain moisture-loving goldenrods (Solidago spp.) can often be found in dampish soils in open areas. They are often found together in the wild, and all three are attractive to pollinators and butterflies.
These natives bloom at the same time in late July through early September, making them a good addition to a moist garden area that could use some color in late summer. There are many native goldenrods that will do fine in drier soils, as well, making them a versatile plant.

Surf the Web on Web Soil Survey!
This month, UConn’s Women in Soil Ecology brings you a word on Web Soil Survey. Are you ever curious about the soil in your yard and wish there was some way you could learn more information about it? You’re in luck, because there is an online web tool that allows you to do just that!
Web Soil Survey is a free online tool that allows you to input an address and select an area of interest to view a soil map and soils data in that area. This information is provided by the National Cooperative Soil Survey, which is operated by the USDA Natural Resources Conservation Service (NRCS). This tool can help you decide what plants to grow based on your soil conditions, as well as aid in other land planning. Web Soil Survey contains a lot of information, but an interesting feature is the soil health data, which can provide descriptions and ratings for key soil health indicators.

In the Garden & Pest Alerts
Tobacco Budworms
Tobacco budworm caterpillars, can be pests of many flowering plants in the tobacco family. Petunias, geraniums, snapdragons and Calibrachoa are just a few of the plants whose buds and flowers can be damaged by this caterpillar.
Check plants that have stopped flowering to see if buds have been eaten or damaged. Check inside flowers for these caterpillars as they have a preference for reproductive flower parts and petals.
Hand- picking them off is the best control method. Most insecticides should not be used on flowers as pollinator may be killed or injured. BtK is normally ineffective.

UConn Pest Alerts
During the growing season, UConn Extension publishes a regular pest alert for both vegetable and fruit producers. Additionally, the New England Vegetable Management Guide offers a lot of information about specific vegetable crops.
While the target audience for these publications is usually commercial growers, home gardeners can learn a lot from these materials including identification and management of common pests in your veggie gardens!
If you ever need confirmation on an ID or have additional questions about what you read in these reports, please do not hesitate to reach out to us at the Home & Garden Education Center! We're happy to help your gardens thrive.

Supplement Your Garden Produce with CT Grown Products!
Connecticut is rich in agricultural history, with many operational farms that have lots to offer local markets!
Supporting local CT Agriculture is a way that gardeners can supplement the fresh foods they grow in their garden, with seasonal offerings from year round operations.
Consider attending a local farmers market, joining Community Supported Agriculture (CSA's), or even stopping by your nearest farm stand to see what they have to offer!
August Gardening Tips
- Lawn seeding, whether it's renovation, repair, or spot seeding should take place between August 15th and September 15th
- Container and hanging plants may need additional water later in the day if hot and windy conditions prevail. Check plants again at day’s end to see if any additional water is necessary
- Fertilize container plantings and hanging baskets if they look yellow with a ½ strength dose of a balanced liquid fertilizer.
- Fertilize perennials with a 5-10-5 or 5-10-10 product to encourage continued blooming.
- Remove old plants that have stopped producing to eliminate a shelter for insects and disease organisms. Replant sites with chard, quick maturing beans or cucumbers, leafy greens etc.
- Put netting on fruit trees and bushes a few weeks before the fruit begins to ripen to protect it from birds and squirrels
- Raise your mowing height to 3 inches during hot weather and mulch clippings if possible
- Even though tomatoes continue to ripen after picking, fruits develop greatest flavor when allowed to ripen on plants. The exception is cherry tomatoes since many varieties are prone to splitting. Pick any almost ripe ones before a heavy rain.
- Renovate strawberry beds by mowing to a height of 1 ½ inches, thinning plants and side-dressing with a balanced fertilizer
- To reduce the number of pests on your fruit trees for the coming year practice good sanitation by removing and destroying all fallen fruit. Do not compost it.
- Do not add weeds with mature seed heads to the compost pile. Many weed seeds can remain viable and germinate next year when the compost is used.
