North American Planting Calendar
Pick your USDA hardiness zone to see when to start seeds indoors, sow or transplant outside, and harvest — across 160+ vegetables, herbs, fruits, flowers, and trees commonly grown in North America. Dates shift automatically with your zone’s average frost dates; trees and perennials show their dormant-season planting windows and, where relevant, bloom or harvest timing.
