Interplant cucumbers and beans to repel cucumber beetles and prevent the wilt diseases they carry. Also plant Cucurbita lagenaria gourds as trap plants for cucumber beetles. Plant potatoes to repel squash bugs. Plant corn in blocks of at least four rows in each direction to assure good pollination. Make succession plantings through the end of June only, as later plantings generally suffer from severe smut problems when they mature in September.
Corn stalks make convenient pole bean supports.
Plant the beans after the corn is 6 inches tall, no sooner, or the beans will outgrow the corn. Then, as the horn-worms wiggle to shake off the water, you can easily see them and remove them. Take no harvests this year from the asparagus, artichokes and rhubarb that you planted this spring. Let the plant use all its energy to develop a good root system, instead of expending it sending up more shoots. Trellises provide support for greater fruit production per square foot of soil and for longer periods because more leaf area is exposed to sunlight for more photosynthesis, and more air circulation means less fruit rot and ground-insect attack.
