When to Plant Lettuce in Texas
Published: April 21, 2026
Texas gardeners in Zone 8a enjoy an extended 41-week growing season for lettuce. Cool-season crops like lettuce 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.
Lettuce Planting Dates for Texas
| Start seeds indoors | January 18–25 |
| Last frost (average) | February 15 |
| Transplant outdoors | January 18–28 |
| Direct sow outdoors | January 4–14 |
| Expect first harvest | February 17 – March 19 |
| Fall crop start | October 20–30 |
| Fall harvest | November 19 |
| First fall frost (average) | December 1 |
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 Lettuce in Texas's Climate
Texas's warm Zone 8a climate makes lettuce 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 lettuce will bolt (send up a flower stalk and turn bitter) before it produces a harvestable crop.
Succession planting stretches the lettuce 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 lettuce pests to watch for in Texas include Aphids and Slugs. The first line of defense is companion planting: Carrot and Radish 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.

Lettuce Growing Tips for Texas Gardeners
- •Direct sow very shallowly — lettuce seeds need light to germinate; cover with just 1/8 inch of soil.
- •Cut outer leaves 1 inch above the crown for "cut-and-come-again" harvests lasting weeks.
- •Texas's cool-season lettuce plants best in October, November, and December for winter and early spring harvest. Spring plantings bolt before producing a harvestable crop.
- •Provide afternoon shade in warmer climates (Zones 7+) to extend the spring window before heat bolts plants.
Companion Planting for Lettuce in Texas
In Texas's warm climate, planting lettuce with Carrot and Radish helps deter pests and improve soil. Avoid planting near Fennel and Celery, which inhibit lettuce growth through root chemistry or shared pest pressure. See the full lettuce companion planting guide for the complete list.
