Summer squash plants are annuals that produce edible fruits in a variety of shapes, sizes, and colors. They are part of the Cucurbitaceae family and include zucchinis, crooknecks, patty pans, and more. These plants prefer warm, sunny climates and well-drained soil with plenty of nitrogen-rich organic matter. Summer squash plants are usually planted in early to mid-spring and are harvested in the summer when the fruits are still immature. Summer squash plants are usually grown in rows and require regular watering and fertilization for optimal growth and production.
