Seed starting calendar for Zone 6

Zone 6's last spring frost lands around April 25 in a typical year. The windows below are the best stretches to start each crop indoors, from the same climate engine the Dibble app uses. Move the seedlings out when the transplant window opens.

Generous season. Spring and fall plantings both productive.

20 crops, in the order they need starting. Crops the engine rules out for Zone 6, or that do not need an indoor start there, are left off; each name opens its full dated page.
