Pick a month and climate to see what to plant right now — start indoors, transplant out, or direct sow. General timing only: for frost-date-precise dates, use the seed-starting calendar.
Pick a month and your climate to see what you can plant right now. General timing only — your frost dates always have the final say.
How it’s figured
Cool climate ≈ cold winters and a short summer (roughly USDA zones 3–5). Warm climate ≈ mild winters and a long, hot summer (roughly zones 8–10). Between the two? Lean toward the cool list in spring and the warm list in fall — and double-check against your actual frost dates, which beat any general calendar.
