- Squash leaves tend to be very large and exhibit three to five lobes. The plant's fruits, flowers, seeds and shoots are edible, along with the leaves. Flowers are large, trumpet-shaped, yellow to orange in color and have separate males and females. Male flowers produce pollen while female flowers mature into fruit. Whether you're growing winter or summer squash, the fruit provides an abundant and continuous harvest.
- Summer types often grow in a compact, bushing fashion with fruit that is usually smaller than winter squash. Harvest summer squash when fruit is still soft and immature, 50 to 65 days after planting. Zucchini is a green summer variety that is quickly ready for picking. Pick it when it reaches 4 to 5 inches in length, but pick varieties like Costata Romanesco when they reach 6 to 10 inches long. This variety produces many male blossoms, ideal for frying and eating. Yellow summer squash includes both straightneck and crookneck types.
- The key to growing winter squash is to allow plenty of room for each plant to spread. These plants can take over a garden with their fast-growing vines. Harvest when fruit is large and mature, usually in fall or winter, 80 to 120 days after sowing. Many types require curing to harden the shell, and are best if baked prior to consumption. The main varieties of winter squash include acorn, buttercup and butternut varieties. Acorn squash is just 2 pounds in weight with a slightly tapered, round acorn shape. Buttercup squash is similar to acorn squash, but larger and slighly flattened. Many of them, including the Sweet Mama cultivar, store well and easily last until February. Butternut squash is tan-colored, exhibits a sweet flavor and has a cylindrical shape with a bulb on the bottom end.
- Squash plants are heavy feeders that grow quickly. They prefer plenty of heat during germination. For summer squash, ideal germinating soil temperature is 95 F, while winter squash germinates best at about 90 F. Direct sowing is best with these plants as they grow fast and do not transplant well. Provide rich, well-drained soil. Winter squash especially needs rich soil as it has a longer growing time and needs more nitrogen than its summertime counterpart. Harvest summer squash as soon as the fruit grows large enough, but do not allow it to over ripen or grow wrinkled in appearance. For winter squash, wait until stems dry and shrivel and skin is hard. Then cure the squash in the sun so the skin can dry completely.
