It is a traditional Native American practice to plant corn, squash (including pumpkins), and beans together. The pumpkin vines cover the soil to make a living mulch, maintaining moisture and smothering weeds, and beans supply nitrogen to both other crops, and climb the cornstalks for support.
Both corn and pumpkins are heavy feeders, so you may want to add extra compost and/or a slow-release fertilizer at planting time.
Deciduous fruits trees such as peaches, apricots, plums and cherries that have flowered and set fruit need to have some of those fruits removed or thinned. Many fruits trees will set more fruits than they can mature. By thinning some fruits now, you'll get larger and tastier mature fruits later. Thin these fruits to about 4 to 6 inches apart on the branch as soon as the fruits are as large as a quarter.
