When to Plant Broccoli in Maryland

Growing Broccoli in Maryland: Complete Guide

Broccoli (Brassica oleracea var. italica) is a warm-season crop that needs a head start indoors before Maryland's last frost. Most Maryland gardeners begin seeds indoors around Friday, February 6, 2026 and move transplants outside around Friday, March 20, 2026, after the risk of frost has passed.

Because Maryland stretches across 5 USDA hardiness zones (6a, 6b, 7a, 7b, 8a), 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 60 days to maturity, Broccoli needs the indoor head start that Maryland's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Broccoli 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.
