Deer damage or feed on a wide variety of fruits and vegetables such as cole crops, lettuce, grapes, corn, pumpkins, berries, tomatoes, fruit trees and other plants. Because white-tailed deer lack upper incisor teeth, the damaged leaves and twigs or stems have jagged edges, compared with a clean-cut surface left by rodents and rabbit feeding. Vegetables are readily eaten and entire gardens may be destroyed. Sweet corn tips are eaten, including the silk and one to two inches of the ear but occasionally plants are grazed to the ground. In addition, deer trample many crops as they move about the field. Deer are active in Connecticut year-round. Breeding occurs from October to December. Fawns are born in May and June weighing about eight pounds at birth and increasing in weight over the next six to seven years. Peak feeding activity occurs in early morning and late evening; thus, deer may damage the garden without being seen. Damage by deer in Connecticut is increasing as residential development forces deer into smaller and smaller habitats and wild food sources decrease.
Deer are protected during all times of the year except various hunting seasons or by obtaining special crop damage permits. All methods of destroying deer such as using traps, poisons, toxic baits, etc. are dangerous to domestic animals and individuals and may result in liability for damage and poor public relations.

Did you receive a plant during this holiday season? Poinsettia, holiday cactus and rosemary trees are filling the shelves in greenhouses, grocery stores and even big box stores appealing to the giver to gift a plant lover on their list. While they are beautiful plants, they will need the correct care to keep them that way and in good health.
The familiar red foliage of the poinsettia plant are modified leaves called bracts. They surround the actual small, yellow flower at the center of the red bracts. Once the pollen from the flowers are shed, the bracts are dropped from the plant. Chose plants with little to no pollen for the bracts to be retained for a longer length of time. Plant breeders are developing different colored bracts, including variegated, offering many options than just red. Read more…
One of the most common plant-problems we see in the lab is interveinal chlorosis. This issue can affect house plants and garden vegetables, to landscape trees and shrubs. We often get inquires about the plant-tissue analysis we offer in the soil testing lab as a means to identify various problems. While this is an extremely useful tool for diagnosing nutrient deficiencies, when we see a plant showing interveinal chlorosis, we usually check the soil test results first.
What is interveinal chlorosis? A good place to start is defining what chlorophyll is. Greek for green leaf, chlorophyll is the pigment in plants that gives them their green color, and traps the light necessary for photosynthesis. Photosynthesis is the process in which plants produce sugar from light energy. The chlorophyll molecule is held together by a central Magnesium ion. Interveinal Chlorosis is a yellowing of the tissue between the veins of a leaf due to the decline of chlorophyll production and activity. A give-away tell of interveinal chlorosis is that the veins generally retain their green color, hence the name, interveinal. When a plant cannot produce chlorophyll it loses its green color and could face stunted growth, fail to produce fruit and flowers, and eventually die.
What causes interveinal chlorosis? The quick version is nutrient deficiency. We already know that Magnesium is a central part in chlorophyll, but there are other essential elements like Iron, Manganese, and Molybdenum that are necessary in many enzyme activities, and a deficiency in one of these nutrients can lead to interveinal chlorosis. In our lab we most commonly see interveinal chlorosis caused by a lack of Iron or Magnesium. When thinking about a nutrient deficiency, it’s important to remember that there are other factors to take into account than just whether the nutrient is present in your growing media. Interveinal Chlorosis brought on by a nutrient deficiency can be caused by a pH imbalance, injured roots or poor root growth, and excessive amounts of other available nutrients in your growing media.
How can you get rid of interveinal chlorosis? We are available in the lab, and in the Home & Garden education center to help you figure out what’s causing your interveinal chlorosis. Once you determine what the cause is, fixing the problem shouldn’t be too difficult. Most of the time it’s a pH issue. If your soil is too alkaline, generally having a pH value of over 6.7, iron becomes more insoluble and less available for absorption. Soil pH can be corrected using a few different approaches, the most common method for acidifying soil is adding Sulfur. Generally, 1 lb Sulfur/100 sq ft will lower pH ~ 1 unit. Nutrient deficiencies can also be remedied using foliar and trunk applications, as well as soil treatments amendments.
Rosemary is not hardy in most areas of Connecticut. Bring plants in before temperatures drop too low but check plants thoroughly for insects such as mealybugs. Rinse the foliage, remove the top layer of the soil surface, and wipe down containers.
Squash and pumpkins should be harvested when they have bright color and a thick, hard skin. These vegetables will be
abundant in farmer’s markets and will make a colorful and healthy addition to fall dinners.
As tomatoes end their production cut down plants and pick up any debris and put in the trash or take to a landfill. Many diseases will over-winter on old infected leaves and stems, so these are best removed from the property.
Cold-hardy fruit trees including Honeycrisp and Cortland apples, Reliance peach, Superior plum, most pawpaws and American persimmon can still be planted into October. Continue to water until the ground freezes hard.
Drain garden hoses and store in a shed, garage, or basement for the winter. Turn off all outside faucets at the inside shut-off valve, turn on the outside faucet to drain any water left in them, and then shut them off.

Scout for C-shaped notches on the edges of the leaves of your perennials such as dahlias, roses, basil or coleus that are caused byAsiatic beetlefeeding.
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.
