When to Plant Turnips in Texas
Published: April 24, 2026
Texas gardeners in Zone 8a enjoy an extended 41-week growing season for turnip. Cool-season crops like turnip 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.
Turnip Planting Dates for Texas
| Start seeds indoors | Year-round |
| Last frost (average) | February 15 |
| Direct sow outdoors | January 25–February 4 |
| Expect first harvest | March 1 – March 26 |
| Fall crop start | October 6–16 |
| Fall harvest | November 10 |
| 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.
⚠ Direct sow turnips 2–4 weeks before last frost for spring crop. Best planted in late summer (6–8 weeks before first fall frost) for fall harvest — frost sweetens the roots. Fast-growing: some varieties ready in just 35 days.
Growing Turnips in Texas's Climate
Texas's warm Zone 8a climate makes turnip 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 turnip will bolt (send up a flower stalk and turn bitter) before it produces a harvestable crop.
Succession planting stretches the turnip 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 turnip pests to watch for in Texas include Flea Beetle and Aphid. The first line of defense is companion planting: Pea and Mint 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.

Turnip Growing Tips for Texas Gardeners
- •Thin seedlings to 4-inch spacing when plants are 3 inches tall — crowded turnips produce small woody roots.
- •Both roots AND greens are edible — harvest baby turnip greens 4 weeks after sowing, roots 5–9 weeks.
- •Texas's cool-season turnip plants best in October, November, and December for winter and early spring harvest. Spring plantings bolt before producing a harvestable crop.
- •Fall turnips are sweetest — plant 8 weeks before first frost and let cold weather convert starches to sugars.
Companion Planting for Turnips in Texas
In Texas's warm climate, planting turnip with Pea and Mint helps deter pests and improve soil. Avoid planting near Potato and Radish, which inhibit turnip growth through root chemistry or shared pest pressure. See the full turnip companion planting guide for the complete list.
