Find the best time to sow seeds indoors and outdoors for vegetables and flowers by month.

Sowing Calendar

A guide to when to start seeds indoors and when to direct-sow or transplant outdoors. Months assume Northern Hemisphere temperate climate (USDA zones 5–8); adjust 2–4 weeks for warmer or cooler regions.

  • Indoors — start seeds in trays under shelter 4–8 weeks before last frost
  • Outdoors — direct sow or transplant after last frost date
  • Last frost dates vary by location — check your local gardening zone
  • Succession sow every 2–3 weeks for continuous harvest
