Planting Calendar by ZIP Code
Nearly every planting instruction you'll read is written as an offset from your last frost — "start indoors 6–8 weeks before last frost", "sow 2 weeks after". This calendar does that arithmetic for you: enter a ZIP code and it converts every offset for 56 crops into real dates for your zone.

Get reminded at the right week
FreePlanting dates are only useful if you remember them. Tell us your zone and we'll email you when it's time to start seeds indoors, when your last frost is close, and when the autumn sowing window opens — dated for your climate, not someone else's.
Seasonal sends only — roughly one a month, more in spring. No selling your address, unsubscribe in one click. Don't know your zone?

How to read the calendar
- Start indoors — sow into trays under lights or on a windowsill. Getting this wrong by a few weeks is the most common seed-starting mistake; too early and you get leggy, root-bound transplants. See starting seeds indoors.
- Plant outside — either transplanting seedlings or direct sowing, whichever that crop wants.
- Fall sowing — a second window for crops that will mature in cool weather, counted back from your first fall frost.
- Harvest from — days to maturity added to the outdoor planting date. Treat it as the earliest plausible date; cool or cloudy seasons push it later.
These are planning dates, not instructions. They come from median frost normals for a whole hardiness zone. Your own garden's records beat them every time — if you have been growing in the same spot for a few years, trust what you have seen over what this table says.
