Zone 6 Planting Calendar

In zone 6 the last spring frost typically passes mid-April and the first fall frost arrives mid to late October. A long, forgiving season on both ends. The calendar below hangs every planting window on those two dates.

How this calendar is made

Derived from each plant's type, USDA hardiness zones and bloom months, crossed with zone 6's typical frost dates, as stored in the BloomsEye library, which was written with AI assistance. Of these 1,651 plants, 662 have been checked against outside sources (99 fully verified); the rest have not been checked yet, and each plant's own page says which. The cards are AI-generated illustrations. Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
