Scallop squash or patty pans should be grown in full sun, in rich, well-draining soil. Once the danger of frost has passed in your area, these little squash can be directly sown into the garden. They are usually planted in groups with two or three seeds per hill and spaced 2 to 3 feet (61-91 cm.) apart. Thin them to one or two plants per hill once the seedlings attain a height of 2 or 3 inches (5-8 cm.) tall. Give them plenty of room to grow like any squash; their vines spread 4 to 6 feet (1-2 m.). The fruit should mature between 49 and 54 days. Keep the squash watered well. There are no secret scallop squash growing tips; the plants are relatively easy to grow.
