Zone 8 Planting Guide: When to Plant Vegetables in USDA Zone 8

USDA hardiness zone 8 (8a and 8b) covers places where the coldest winter night averages 10 to 20°F. This guide times seed-starting, transplanting, and fall planting for a typical zone 8 last frost of Mar 24 and first fall frost of Nov 10. Plant cool-season crops in fall and late winter; summer heat can stall tomatoes in midsummer.

About these dates: Timings are counted from your average last spring frost date, which is only an average — a frost can still occur after it. Dates vary within a state by elevation, distance from water, and microclimate. Look up the frost date for your ZIP code (your state Cooperative Extension office or NOAA climate normals are good sources) and adjust for the current season’s weather and soil temperature.
