Zone 7a averages 198 frost-free days, running from a last spring frost around April 10 to a first fall frost around October 25. Squash (winter) needs roughly 95 days from planting out to first harvest, so it uses about 48 percent of that window. Squash (winter) is a tender crop, which is what decides where in the window it belongs.

Because squash (winter) needs a head start, sow seed indoors around Mar 20, about 3 weeks ahead of the Zone 7a last frost. Transplants go out around Apr 24. Starting earlier than that in Zone 7a usually backfires: plants outgrow their cells and stall when they finally hit cold soil.
