Cool-Season Vegetable

When to Plant Broccoli in Texas

A nutrition powerhouse that thrives in cool weather. Harvest the main head, then enjoy weeks of side shoots.

The Short Answer

Broccoli in Texas is a cool-season treasure — plant in fall for a winter harvest that takes advantage of the state's mild cool weather. Spring broccoli is possible in north Texas but the window is narrow before heat arrives. Texas gardeners who master cool-season vegetables like broccoli can keep their gardens productive year-round.

Growing Broccoli in Texas

State-Specific Growing Tips

Fall (primary season): start seeds indoors in August, transplant in September (north Texas) through October (south Texas). Spring: start seeds indoors in January, transplant in late February (north Texas only — south Texas is too warm for reliable spring broccoli). Texas's mild winters in the southern half allow broccoli production from October through March. Broccoli is a heavy feeder — amend with compost and nitrogen at planting and again when heads form.

Recommended Varieties for Texas

Green Magic and Belstar are heat-tolerant varieties suited to Texas's warm cool-season conditions. Marathon for later fall planting. DeCicco for extended side-shoot harvest. Texas A&M recommends heat-tolerant varieties that head reliably in Texas's mild but sometimes warm 'winter' temperatures.

Common Challenges in Texas

Cabbage loopers, imported cabbageworms, and diamondback moth are all present in Texas — Bt is essential. Aphids colonize developing heads. Bolting if temperatures spike during heading. In south Texas, the cool season may not be cold enough for proper heading — choose heat-tolerant varieties.

Growing Tips

Harvest main head while buds are tight. Side shoots will continue producing for weeks after the main harvest.

Companion Planting

Plant broccoli alongside these companions for better growth:

Beets Celery Onions Potatoes

Keep broccoli away from:

Tomatoes Peppers Strawberries

The Bottom Line

Broccoli can be grown successfully in Texas with proper attention to regional frost dates and local growing conditions. Timing varies across the state — North Texas (Dallas) gardeners work with a last frost around Mar 10 - Mar 25, while East Texas sees frost end around Mar 1 - Mar 20. Choose varieties suited to your region, amend your soil based on its specific needs, and monitor for the pests and diseases most common in your area.
