Zone 9A Vegetable Planting Calendar

Scored per crop from your zone's frost dates, each crop's days-to-maturity, and typical soil temperatures — honestly, including when not to plant.

A zone caveat: USDA zones reflect winter lows, not summer heat — this calendar is a zone-level guide. For timing tuned to your exact zip code, sun, and soil, get your free AI garden plan.

A single frost date is a coin flip dressed up as a fact: these are the 50/50 dates, and about half of years see frost past them. Across 4,330 NOAA stations, frost odds typically stay near 1 in 3 for about a week past the date and don't drop below 1 in 10 until roughly 16 days past it — cautious growers wait those two-plus weeks; gamblers plant on the date and keep row cover handy. The free AI plan reads the real percentile dates for your zip and lets you pick your risk.
