Planting
When to plant a garden in Central Texas can mean the difference between a bountiful harvest and wilted dreams by mid-May. The ideal planting window here isn't one-size-fits-all—spring and fall are your golden opportunities, but summer's brutal heat forces most gardeners to take a break unless they're growing heat-lovers like okra or sweet potatoes.
If you've ever planted too early and lost everything to that sneaky March frost or waited too long and missed peak harvests, you know how critical the calendar is.
Central Texas's 8a-8b climate gives us about 215 frost-free days, but that doesn't mean you can plant anytime—soil temperature and heat tolerance matter just as much as dates.
I've spent years perfecting the schedule for General Garden Plants 🌱 here, and what works for tomatoes in Austin might fail in Waco's slightly hotter microclimate. Let me show you exactly when to plant each type—from cool-season greens to heat-tolerant veggies—so you can maximize your garden's potential without the guesswork.
We'll cover everything from late February prep to October planting, including how to beat Central Texas's two biggest enemies: unpredictable freezes and scorching summers. Ready to grow smarter, not harder?
Central Texas planting calendar by season: exact dates for frost-free success
Central Texas gardeners face a unique challenge: scorching summers and unpredictable freezes. The key to success? Timing your plants to avoid both extremes. Unlike northern climates, we don’t have a long cool season—so spring and fall become our prime planting windows.
But even then, microclimates in Austin, Waco, and San Antonio can shift ideal dates by weeks.
According to Texas A&M AgriLife, the average last frost date for Central Texas is mid-March, but urban areas like Austin often see frost 2-3 weeks later. Meanwhile, first frost typically hits mid-November, though early freezes can strike as soon as late October.
These dates are your garden’s lifeline—plant too soon and risk frost damage; too late and face 100°F+ soil, which stunts growth.
Here’s how to master the Central Texas planting calendar with exact dates for frost-free success, broken down by season and plant type. This schedule accounts for heat tolerance, soil warmth, and regional variations so you can grow year-round without guesswork.
| Season | Planting Window | Key Crops | Soil Temp Requirement | Notes |
|---|---|---|---|---|
| Spring | Late February - Early April | Tomatoes, Peppers, Lettuce, Onions, Carrots | 60°F+ (use row covers for early starts) | Wait until after March 15 for Austin; earlier in rural areas. |
| Summer | After May 15 (heat-tolerant crops only) | Okra, Sweet Potatoes, Black-Eyed Peas, Eggplant | 75°F+ (mulch heavily to retain moisture) | Avoid planting before May 15—soil and air temps are lethal for most veggies. |
| Fall | September - October | Broccoli, Kale, Spinach, Radishes, Green Beans | 55°F+ (cool soil speeds germination) | Plant by September 15 for harvests before first frost; use row covers to extend season. |
| Winter | November - January (cold-hardy crops) | Garlic, Onions, Spinach, Arugula, Peas | 40°F+ (protect with mulch) | Plant garlic in November for summer harvest; other greens tolerate light freezes. |
Spring planting in Central Texas starts earlier than you think.
While late February is safe for cold-hardy crops like peas and spinach, wait until March 15 for tomatoes, peppers, and basil—these heat-loving plants won’t tolerate frost. Soil temperature is your best guide: Use a soil thermometer to confirm it’s at least 60°F before planting warm-season crops.
Pro tip: If you’re in Austin or San Antonio, hold off until after March 20—these cities experience later frosts due to urban heat islands. For Waco and rural areas, you can plant 1-2 weeks earlier. Row covers (floating fabric tunnels) let you start 4-6 weeks earlier by trapping heat and shielding seedlings from late frosts that can hit as late as April 1.
Summer gardening in Central Texas is all about heat tolerance. Once May 15 rolls around, the brutal heat (often 100°F+) makes traditional veggies like lettuce and broccoli wilting disasters.
Instead, focus on okra, sweet potatoes, black-eyed peas, and eggplant—these thrive in heat and can handle drought-like conditions better than most. Mulch heavily (3-4 inches of straw or wood chips) to retain moisture and keep roots cool.
Fall is your second chance for a bountiful harvest, but timing is critical. September 15 is the last safe date to plant cool-season crops like broccoli and kale if you want to harvest before the first frost (usually mid-November). Soil warming tricks—like black plastic mulch or clear plastic tunnels—can extend your season by 2-3 weeks.
For maximum yield, plant fast-maturing varieties (e.g., ‘Early Purple’ broccoli, which matures in 50 days).
Winter gardening in Central Texas is all about cold-hardy crops. Garlic and onions planted in November will overwinter and produce in June. Leafy greens like spinach and arugula can handle **light
Best heat-tolerant vegetables for Central Texas summers: what to plant after May 15
Central Texas summers are brutal—temperatures often hit 100°F+, and most garden vegetables wilt under that kind of heat. But don’t let the scorching sun stop you from growing! The key is choosing heat-tolerant varieties that thrive when others fail.
After May 15, focus on plants that love the heat and can handle drought-like conditions. These varieties won’t just survive—they’ll flourish, giving you a bountiful harvest when other gardens are struggling.
My top picks for summer planting in Central Texas include okra, sweet potatoes, black-eyed peas, and malabar spinach. These plants aren’t just heat-resistant; they actually perform better in high temperatures.
For example, okra grows faster and produces more pods when it’s hot, while sweet potatoes thrive in the dry heat. By planting these after May 15, you’ll avoid the risk of early-season freezes and take full advantage of the long, sun-drenched days.

Top 10 Heat-Tolerant Vegetables for Central Texas Summers
- Okra – Thrives in 90°F+ heat; plant after May 15 for best results.
- Sweet Potatoes – Loves heat and drought; harvest in 100-120 days.
- Black-Eyed Peas – Drought-resistant; plant June-July for fall harvest.
- Malabar Spinach – Heat-loving vine; harvest leaves as needed.
- Eggplant – Prefers warm soil; plant after May 15 for best growth.
- Peppers (Hot & Sweet) – Heat enhances flavor; plant April-May.
- Cowpeas – Fixes nitrogen in soil; drought-tolerant and prolific.
- Tomatoes (Heat-Tolerant Varieties) – Choose ‘Heatmaster’ or ‘Solar Fire’ for summer.
- Sorghum – Drought-resistant grain; great for dry summers.
- Amaranth – Heat-loving leafy green; harvest young for tender leaves.
When planting these heat-tolerant crops, start by preparing your soil with compost and mulch to retain moisture. Central Texas soil can dry out quickly, so deep watering in the morning is crucial.
Avoid overhead watering, which can lead to fungal issues in the heat. Instead, use drip irrigation or soaker hoses to deliver water directly to the roots where it’s needed most.
Another pro tip: plant in raised beds or containers if your yard has heavy clay soil. This improves drainage and helps roots stay cool. For example, okra and sweet potatoes both prefer well-draining soil, and raised beds can make a world of difference during our 100°F+ heatwaves.
If you’re using containers, choose ones that are at least 12 inches deep to accommodate root growth.
Don’t forget to monitor for pests like aphids and spider mites, which thrive in hot, dry conditions. A strong spray of water in the early morning can often knock them off plants before they cause damage.
For extra protection, consider using neem oil or insecticidal soap, which are effective and safe for edible crops. With these strategies, your summer garden will not only survive but thrive, giving you fresh produce long after most gardens have given up.
