Houseplantscan dry out quicker in the heat and extra sunlight of summer. Check them frequently to evaluate their moisture needs.
Keep an eye out for insect, slug, and snail damage throughout the garden. Use the controls in our fact sheetSnails and Slugs.
Remove old plants that have stopped producing to eliminate a shelter for insects and disease organisms. Replant sites with chard, quick maturingbeansorcucumbers, leafy greens etc.
Even thoughtomatoescontinue 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.
Pick up, bag, and trash (do not compost) any dropped apples that show signs of apple maggot.
Tomato hornworms are large green caterpillars that feed on the leaves of tomatoes and related plants. Hand-pick or control with Bacillus thuringiensis. Do not remove caterpillars that are covered in white pupae as they have been parasitized by beneficial wasps.
Check brassicas for cabbageworm, diamond-back moth caterpillars, cross-striped caterpillars, and cabbage loopers. Use row covers or Bacillus thuringiensis to control them.

The UConn Extension Master Gardener program is a program that offers many different opportunities through the horticulture world. There are many qualities that are vital to becoming a Master Gardener, such as being eager to educate your community, participating in training programs, and wanting to learn more about plant care and gardening. It is never too late to become a Master Gardener. Applications are available now at MasterGardener.UConn.edu and due October 9th.
Once you have enrolled to be a Master Gardener, you will start working on your certification to become an official Master Gardener. Some things that you need to do to achieve this certification is completing a 16-week course that meets once a week, and complete a 60 hour internship that includes working in one of 9 UConn Extension offices statewide for hands on training, and working on a community outreach program. Rebecca Foss, one of the class of 2015 Master Gardeners talks about her experience in the Master Gardner’s office in the Tolland County Extension office, and how she was always eager to help out with anyone that had questions about plants.
“One of the most rewarding experiences was in the Tolland Master Gardner office. I had approached my office hours with an open mind but some underlying (but mild) trepidation as I wondered whether or not I would be able to actually make a correct diagnosis.” Rebecca later found a piece of pine that had some sort of disease on it and the owner of the pine wanted to figure it out so he could try and treat it. Rebecca and her co-worker went underway to try and figure out what they were dealing with. “We quickly ruled out some causes (we hadn’t had a drought last year) and focused on others. Soon, diplodia tip blight (Sphaeropsis sapinea), which my partner found in a book, began to look like the potential culprit.” Rebecca states. Once Rebecca and her partner got the specimen under the microscope, “I looked under the papery leaf sheaths as recommended and… Bingo! There they were!”
The Master Gardener Program is full of many different opportunities for you to learn new things about plants, but to also fulfill a lifelong hobby you may never have thought pursuing. Learn more at MasterGardener.UConn.edu
Some garden perennials were not so lucky this winter. If it appears the voles and chipmunks have been busy feeding and tunneling their way through parts of the garden, you will see heaved up tunnels in the lawn from moles. Fill in any tunnels. Mouse traps sent in the runs might work as a control measure. Cover the trap with an up-side-down bucket to keep out birds and cats.
There is still time to remove, crush and kill gypsy moth eggs from tree bark. Hope for a wet spring to develop the fungus that infects the young caterpillars after they hatch from any egg masses that were left.
While cleaning up garden debris, watch for beneficial insect overwintered eggs like the praying mantid’s egg case below. Carefully remove the stem and egg mass to a safe place outside so it can hatch naturally when the weather warms. Do NOT bring it into your home unless you want it to hatch inside your heated house!
Another spring chore can be done inside the home. Cut the top six inches off of leggy houseplants to give them a good pruning. Repot any that need it to get them ready for another year of growing. Stick some cuttings in a vase of water to get them to produce roots. Some plants do respond better than others and it is worth a try to produce new, free houseplants to share with friends.
Spring has sprung, and it’s time to get seedlings in the ground!

Black knot of plum and cherry, caused by the fungus Apiosporina morbosa, may be overlooked during the growing season when the leaves are hiding the galls, but this time of year they are hard to miss, especially when they are as abundant as they are on the tree in the photo below.
This is a serious disease of these trees and can eventually kill susceptible varieties. Management options include sanitation, resistant varieties and properly timed fungicides.
Where manageable, prune out all galls during the dormant season and dispose of them off-site, burn or bury them. This is because even removed galls may still produce spores that can cause new infections. Prune 6″ below the visible edge of the gall because the fungus can be invading the wood in that area prior to gall development.
This disease can affect both orchard and ornamental varieties of plum and cherry but some of the tart cherries are less susceptible. Native wild cherries are hosts of the disease and provide a reservoir of inoculum for orchards and ornamentals. It’s helpful to remove those nearby where possible. For new plum plantings (fruiting/orchard), ‘President’ is highly resistant. Moderately resistant options include ‘Methley’, ‘Milton’, ‘Early Italian’, ‘Brodshaw’, ‘Fellenberg’, ‘Shiro’, ‘Santa Rosa’ and ‘Formosa’. ‘Shropshire’ and ‘Stanley’ are considered quite susceptible.
Here’s how disease develops: Infections occur in the spring on new growth from spores produced on the surface of 2+ year old galls. Spores are produced and spread during rainy weather and shoots must remain wet for a period of time for the spores to germinate and initiate an infection. Infections can occur at temperatures of 50°F or higher when water is present for the required period of time. Over the course of the first summer, a small greenish brown swelling develops. By the end of the second summer, the gall or knot becomes hard, rough and black. These galls begin producing spores the following spring. Galls expand in size each year until the branch is girdled (killed all the way around) and then they die. Once a twig or shoot is girdled, the portion beyond the gall can’t get any water or nutrients and dies as a result. Sometimes, larger branches and trunks can become infected, presumably through wounds.
What if you have a susceptible tree and want to prevent this disease? If you know you have a source of infection (hosts with galls nearby, either wild or on a neighboring property) and you’ve had some infections, keep up with the monitoring and pruning, fertilize and water as necessary to prevent stress, and use preventive fungicides, such as lime sulfur during dormancy (organic option) or chlorothalonil or others labeled for this disease. Other than lime sulfur, applications should be made as directed on the label beginning at bud swell and until new terminal growth ceases.
Over the weekend, before the most recent snow, I looked out my kitchen window to see my dog squatting over the chive patch in our vegetable garden. It was too late to stop him.
I spend a lot of time with Connecticut farmers, talking about producing safe fruits and vegetables. We always talk about how animal feces can affect food safety. Animals and birds are often the source human pathogens or microorganisms that can make us sick. Some examples of those pathogens include E. coli O157:H7 (associated with many outbreaks tied to meat, poultry and fresh produce, most recently lettuce); Salmonella (eggs, poultry, pork, sprouts, cucumbers and cantaloupe); and Listeria monocytogenes (all types of foods, including processed meats, cheese, cantaloupe, apples, and frozen vegetables).
Wildlife can spread human pathogens by depositing feces in fields or water sources and spreading fecal contamination as they move. This is very difficult to control. Complete exclusion may not be possible, depending on the species of wildlife. It can be a tough job for farmers to exert any kind of control over geese, other birds, deer, or rodents.
Generally speaking, a home garden is a more manageable space. There are things you can do to discourage the presence of wildlife, though nothing is fail-proof. The first thing you may have to do is to identify the pest. Once you know which animal is eating the lettuce or leaving droppings around, knowledge of their habits and food needs can help you choose the best method to deter them. The University of Connecticut www.ladybug.uconn.edu site has fact sheets that give advice regarding control of wildlife in your yard. In addition, take a look at http://npic.orst.edu/pest/wildyard.html for additional suggestions on specific species.
Here are some suggestions that may help:
Fence your garden. Fences can make for good neighbors, they say, and this is certainly true of fences that keep animals away from your tomatoes. The fence can be as simple as a strong wire mesh. You may have to bury the fence several inches into the ground to prevent creatures from burrowing under the fence. Some animals are perfectly capable of climbing the fence to get to the other side (did someone say, “squirrel”?). A metal shield at the top of the fence might be useful.
Be careful where you hang your bird feeders/houses/bird baths. If birds are feeding or nesting at the bird feeders or houses you have purposely added to your yard, they will be more than happy to poop on your plants as they fly back and forth. This is a lesson easily learned as our birdhouse attracts lots of birds and their droppings on our patio furniture and patio tomatoes alike.
In addition, do not let garden trash build up—dropped fruit and pulled weeds can feed and shelter small animals. Cover trashcans, compost bins and other potential sources of food. Remove pet food or birdseed from the yard.
Use decoys or other deterrents. While these can be effective on a variety of wildlife, it is important to move the decoys every few days. Deer, birds and rodents may be smarter than the average bear: they can figure out when a fake coyote is fake.
One of the most difficult “pests” in the backyard vegetable garden can be Fido or Fluffy—resident dogs and cats. Fencing is most likely to help keep the dog away. Of course, you need to remember to close the gate. An open gate turned out to be how my dog got into the chive patch.
Cats love the soft soil of a garden and WILL use it as a litter box. Of course, the best course of action is not to let your cat out at all. There are too many ways they can get injured, sick, or worse whether you live in a city, suburb, or on acres of land.
If the dog gets through the gate or over the fence and poops on your edibles, there is little you can do. If it is early in the season and the plant has no edible parts, you can wait 120 days to harvest, treating the feces like raw manure—feces from another species. If harvestable or close to harvestable produce is affected, it is best to leave it on the plant. Do not harvest, do not eat; do not harvest, wash and eat. It is just too risky.
This would be true if you see signs that indicate the presence of other wildlife as well. Bird poop on the tomatoes or lettuce leaves; mouse droppings in the herb bed; or evidence that rabbits have been gnawing on the cucumbers. You really should not eat any fruits or vegetables that have been pooped upon. Washing is not necessarily going to totally eliminate any risk from human pathogens that might have been left behind. Do not toss affected produce in the compost bin either. Animal feces should never be added to compost that will be used on edible plants.
This advice is especially important if you have kids, seniors or others in your family who might have a compromised immune system. It is just not worth the risk.

Garden Master Classes are offered through the UConn Extension Master Gardener Program. For Certified Master Gardeners they provide continuing education as part of the Advanced Master Gardener certification process.
These classes are also open to the general public. Anyone with an interest in gardening and horticulture is welcome!
The UConn Extension Master Gardener Program is an Educational Outreach Program that is part of UConn Extension. The program started in 1978 and consists of horticulture training and an outreach component that focus on the community at large. Master Gardeners are enthusiastic, willing to learn and share their knowledge and training with others. What sets them apart from other home gardeners is their special horticultural training. In exchange for this training, Master Gardeners commit time as volunteers working through their local UConn Extension Center and the Bartlett Arboretum in Stamford to provide horticultural-related information to the community.
