Quick Tips for Using This Calendar

  • Microclimates matter. South-facing walls, raised beds, and urban heat islands can shift your effective zone by half a zone warmer.
  • Succession plant lettuce, radishes, and beans every 2–3 weeks for continuous harvest.
  • "After frost" means after your last frost date, not after the last cold day. Soil temperature matters too — tomatoes need 60°F+ soil.
  • Use row covers to extend your season 2–4 weeks in either direction.
  • Always check companion planting compatibility when planning your layout.
