When to Plant Cauliflower in Virginia

Growing Cauliflower in Virginia: Complete Guide

Cauliflower (Brassica oleracea var. botrytis) is a warm-season crop that needs a head start indoors before Virginia's last frost. Most Virginia gardeners begin seeds indoors around Friday, February 27, 2026 and move transplants outside around Friday, April 10, 2026, after the risk of frost has passed.

Because Virginia stretches across 6 USDA hardiness zones (6a, 6b, 7a, 7b, 8a, 8b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 75 days to maturity, Cauliflower needs the indoor head start that Virginia's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Cauliflower requires full sun (6 hours) and regular (1-1.5 inches/week) moisture. Mid-Atlantic summers bring heat and humidity — ensure good air circulation and watch for fungal issues like powdery mildew.
