Watch out for slugs and snails. Moist spring weather brings them out in force. An hour after nightfall, check your tender plants with a flashlight and hand-pick snails and slugs off foliage.
To deter snails, sprinkle wood ash or crushed egg shells around plants.
Catch stink bugs early. Their eggs laid in neat rows soon will start appearing on the underside of leaves. The young stink bugs look like long-legged aphids. They can be controlled by such organic products as Nature's Pest Fighter, Safer brand insecticidal soap or Bug Buster-O. Or, with gloves, pick them off and drop them in an old coffee can containing an inch of soapy water. Then, cover the can and dispose of it.
With warmer weather comes mosquito season. Empty standing water out of saucers under pots. Also, eliminate any other standing water that may have accumulated during recent rains.
