Hills and rows of summer squash should be approximately 3 to 4 feet apart while winter squash should be spaced approximately 4 to 5 feet apart with 5 to 7 feet between rows and with the hills spaced about 3 feet apart. Squash can be started indoors 3 to 4 weeks prior to the planting date. Start seeds in peat pots but be sure the squash seedlings do not suffer root disturbances during transplanting. You can plant 3 to 4 seeds per pot and thin to 2 plants later.
