When to Plant Brussels Sprout in Florida

Growing Brussels Sprout in Florida: Complete Guide

Brussels Sprout (Brassica oleracea var. gemmifera) is a warm-season crop that needs a head start indoors before Florida's last frost. Most Florida gardeners begin seeds indoors around Thursday, October 9, 2025 and move transplants outside around Thursday, January 1, 2026, after the risk of frost has passed.

Because Florida stretches across 7 USDA hardiness zones (8b, 9a, 9b, 10a, 10b, 11a, 11b), 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 84 days to maturity, Brussels Sprout needs the indoor head start that Florida's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Brussels Sprout requires full sun and regular moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
