Pests/Diseases

Tomatoes are susceptible to insect pests, especially tomato hornworms and whiteflies. Link to our pest & problem pages below.

• Aphids
• Flea Beetles
• Tomato Hornworm
• Whiteflies
• Blossom-End Rot
• Late Blight is a fungal disease that can strike during any part of the growing season. It will cause grey, moldy spots on leaves and fruit which later turn brown. The disease is spread and supported by persistent damp weather. This disease will overwinter, so all infected plants should be destroyed. See our blog on “Avoid Blight With the Right Tomato.”
• Mosaic Virus creates distorted leaves and causes young growth to be narrow and twisted, and the leaves become mottled with yellow. Unfortunately, infected plants should be destroyed (but don’t put them in your compost pile).
• Cracking: When fruit growth is too rapid, the skin will crack. This usually occurs due to uneven watering or uneven moisture from weather conditions (very rainy periods mixed with dry periods). Keep moisture levels constant with consistent watering and mulching.

Harvest/Storage

• Leave your tomatoes on the vine as long as possible. If any fall off before they appear ripe, place them in a paper bag with the stem up and store them in a cool, dark place.
• Never place tomatoes on a sunny windowsill to ripen; they may rot before they are ripe!
• The perfect tomato for picking will be firm and very red in color, regardless of size, with perhaps some yellow remaining around the stem. If you grow orange, yellow or any other color tomato wait for the tomato to turn the correct color.
• If your tomato plant still has fruit when the first hard frost threatens, pull up the entire plant and hang it upside down in the basement or garage. Pick tomatoes as they ripen.
• If temperatures start to drop and your tomatoes aren’t ripening, watch this video for tips.
• Never refrigerate fresh tomatoes. Doing so spoils the flavor and texture that make up that garden tomato taste.
• To freeze, core fresh unblemished tomatoes and place them whole in freezer bags or containers. Seal, label, and freeze. The skins will slip off when they defrost.
• You can harvest seeds from some tomato varieties
