When to Plant Broccoli in Tennessee

Growing Broccoli in Tennessee: Complete Guide

Broccoli (Brassica oleracea var. italica) is a warm-season crop that needs a head start indoors before Tennessee's last frost. Most Tennessee gardeners begin seeds indoors around Sunday, February 22, 2026 and move transplants outside around Sunday, April 5, 2026, after the risk of frost has passed.

Because Tennessee stretches across 4 USDA hardiness zones (6b, 7a, 7b, 8a), planting windows can shift by as much as two to four 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 Tennessee'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. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
