When to Plant in Texas

Texas planting dates vary a lot — Gulf Coast gardeners start earlier than North Texas, and higher elevations stay cooler longer. The Panhandle can see frost well into April, while the Gulf Coast is nearly frost-free.

Most Texas gardeners deal with two challenges: a late spring frost and scorching summer heat. The window between the two can be narrow, making timing critical for warm-season crops like tomatoes and peppers.

Common Mistakes

Planting tomatoes too late — the intense summer heat above 95°F causes blossom drop, so get them in early.
Ignoring the fall season — Texas autumns are ideal for a second round of cool-season crops.
Not mulching heavily — Texas heat dries out soil fast, and mulch is essential for moisture retention.
Assuming all of Texas has the same climate — the Panhandle and Gulf Coast are completely different growing zones.

FAQ

What is the last frost date?

The last frost date is the typical date in spring when your area has its final frost. After this date, it's generally safe to plant warm-season crops outdoors.

When should I start tomatoes indoors in Texas?

Start tomato seeds indoors about 6–8 weeks before your last frost date. In most of Texas, that means starting in January or February depending on whether you're in the north or south.

Can I plant before the last frost?

Yes — cool-season crops like lettuce, peas, spinach, and broccoli can handle light frost and should be planted 4–6 weeks before your last frost date.

Why does timing vary so much within Texas?

Texas spans multiple climate zones. The Gulf Coast is subtropical, the Panhandle gets harsh winters, and the Hill Country falls somewhere in between. Frost dates can differ by over a month.

What if I live in a frost-free area?

Parts of the Rio Grande Valley and Gulf Coast rarely see frost. You can start warm-season crops earlier, but watch for unexpected cold snaps. Enter your zip code in the app for personalized dates.
