When to Plant Broccoli in Texas
Published: April 21, 2026
Texas gardeners in Zone 8a enjoy an extended 41-week growing season for broccoli. Cool-season crops like broccoli do best in fall, winter, and early spring in Texas — the hot summers bolt these plants before they can be harvested. This guide gives exact dates for Texas based on your local frost calendar.
Broccoli Planting Dates for Texas
| Start seeds indoors | January 4–11 |
| Last frost (average) | February 15 |
| Transplant outdoors | January 18–28 |
| Direct sow outdoors | January 18–28 |
| Expect first harvest | March 19 – April 8 |
| Fall crop start | September 22–October 2 |
| Fall harvest | November 21 |

Dates above assume Zone 8a, the most common zone in Texas. Gardeners in cooler Denton (Zone 7b) plant 1–2 weeks later; warmer McAllen (Zone 9b) can plant 1–2 weeks earlier.
Growing Broccoli in Texas's Climate
Texas's warm Zone 8a climate makes broccoli a fall, winter, and early spring crop rather than a summer one. The cool-season window runs roughly October through April in Texas — plant outside this window and the broccoli will bolt (send up a flower stalk and turn bitter) before it produces a harvestable crop.
Succession planting stretches the broccoli harvest window. Sow small amounts every two weeks from October through February — you will have staggered harvests rather than a single wave to process all at once. Bolt-resistant varieties extend the usable window an extra three to four weeks into warming weather.
Common broccoli pests to watch for in Texas include Cabbage Worm and Cabbage Looper. The first line of defense is companion planting: Onion and Garlic planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.

Broccoli Growing Tips for Texas Gardeners
- •For spring: start indoors 6 weeks before last frost and transplant outdoors 4 weeks before last frost.
- •For fall: start indoors in summer — count 10 weeks back from your first fall frost date.
- •Texas's cool-season broccoli plants best in October, November, and December for winter and early spring harvest. Spring plantings bolt before producing a harvestable crop.
- •Harvest heads before any yellow flowers open — once flowers show, flavor declines quickly.
