Large numbers, however, can cause leaves to curl and drop prematurely. Most aphid damage occurs when temperatures are mild. With high summer heat, the population may decrease. Periodically, wash off aphids with a strong stream of water. Bands of sticky material applied to tape which is attached to the tree trunk can prevent ants from climbing up the trees.
Many vegetables are well suited to container growth.
Containers should be of sufficient size that plants have room to develop. Tomatoes are the leading container vegetable. Peppers, including bell peppers and hot peppers are a good choice as are eggplants. Some root vegetables, such as radishes, carrots, and scallions grown from sets, fare well as do many herbs. In the spring and fall, lettuce and spinach can be grown.
