Peas and Snap Beans – since peas and beans are so much alike, lets just group them together. In fact, there are debates saying that peas and beans are the same thing. I personally divide peas and beans into 2 groups – one you eat whole (snap beans) and one you shell to get the bean/pea out of the inside and eat it instead of eating the husk.
Peas and beans return nitrogen into the soil, so that makes them good for crop rotation. Before you plant a high nitrogen requirement crop, such as corn, plant some beans or peas at the same time, or the season before the you plant the corn.
One of the problems with peas and beans – wildlife love it. Deer and rabbits will eat the bean / pea plants down to nothing but a stub sticking out of the ground. To protect the bean and pea plants, plant some squash or zucchini with them. The pea / bean plants will provide the squash plants with nitrogen, and the squash plants will help protect the pea plants from deer. The squash and zucchini plants have little “hairs” on the stalks that the deer do not like.
