(Cucurbita spp.) 15 seeds per packet (unless otherwise noted). Warm and highly manured soil is required for the most successful culture of Squash. The summer kinds, nearly all of which are of bush growth, should be planted in hills 4 feet apart each way, while the winter and other running varieties require 8 to 10 feet. When thinning, leave only 3 or 4 plants to a hill. Winter Squashes and Pumpkins are frequently grown in cornfields, 3 or 4 seeds being dropped in every third or fourth hill at the same time as the Corn.
