Zone 6a averages 176 frost-free days, running from a last spring frost around April 20 to a first fall frost around October 13. Eggplant needs roughly 85 days from planting out to first harvest, so it uses about 48 percent of that window. Eggplant is a tender crop, which is what decides where in the window it belongs.

Because eggplant needs a head start, sow seed indoors around Feb 23, about 8 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.

Fall planting: eggplant in Zone 6a

Eggplant has no useful fall window in Zone 6a. Eggplant needs a long warm run to finish, so a second planting is realistic only in zone 9 and warmer.

Eggplant needs a long warm run to finish, so a second planting is realistic only in zone 9 and warmer.

Fall dates are counted backward from the Zone 6a average first frost, not forward from a sowing date. See the fall planting calendar by zone for the full method.
