Zone 6a averages 176 frost-free days, running from a last spring frost around April 20 to a first fall frost around October 13. Pumpkins needs roughly 100 days from planting out to first harvest, so it uses about 57 percent of that window. Pumpkins is a tender crop, which is what decides where in the window it belongs.

Because pumpkins needs a head start, sow seed indoors around Mar 30, about 3 weeks ahead of the Zone 6a last frost. Transplants go out around May 4. Starting earlier than that in Zone 6a usually backfires: plants outgrow their cells and stall when they finally hit cold soil.
