When to plant in Riverview, FL

USDA Zone 10a

Riverview, Florida frost dates, USDA zone, and a full-year planting calendar, drawn from the nearest NOAA station and tuned to the local season.

Riverview's growing season is short at roughly -11 days, so succession planting is limited; lean on transplants over direct sowing for anything slow to mature. These dates come from a station roughly 16 km away, the closest with full normals; terrain around Riverview (elevation, water, pavement) can move your real frost dates a few days either way. Zone 10a is warm enough that Riverview can grow subtropical perennials, and the short (or absent) frost period barely limits the annual calendar.
