Have you ever planted seeds or seedlings only to watch them wilt under the Texas sun—or freeze in an unexpected frost? You’re not alone. I’ve been there too. After years of trial, error, and a few heartbreaking garden failures, I finally cracked the code with a reliable North Texas planting calendar. Whether you’re growing tomatoes in Denton, herbs in McKinney, or native wildflowers in Fort Worth, timing is everything.
Gardening in North Texas is uniquely rewarding—but only if you work with the climate, not against it. The region’s USDA Hardiness Zones 7b to 8a bring hot summers, mild winters, and unpredictable spring swings. That’s why a tailored planting schedule isn’t just helpful—it’s essential. In this guide, I’ll share the exact months to sow, transplant, and harvest based on real experience from my backyard in Collin County.
I started gardening seriously five years ago, frustrated by store-bought produce that lacked flavor. I wanted fresh basil, juicy peppers, and crisp lettuce—right outside my kitchen door. But without knowing when to plant what, I wasted money and time. Now, thanks to local extension resources, soil tests, and plenty of trial runs, my garden thrives year-round. And I’m passing those hard-earned lessons to you.
By the end of this article, you’ll have a clear, month-by-month roadmap for planting vegetables, herbs, flowers, and native plants perfectly suited to North Texas conditions. No guesswork. Just practical, proven advice from someone who’s grown it all—and learned from every mistake.
Your North Texas Planting Calendar at a Glance
Below is a quick-reference table I use every season to plan my garden. It covers the most popular crops and their ideal planting windows across North Texas counties like Dallas, Tarrant, Denton, and Rockwall.
| Plant Type | Best Planting Time | Harvest Window | Key Tips |
|---|---|---|---|
| Tomatoes | Late February–Early March (indoors); transplant after last frost (mid-March) | June–September | Use black plastic mulch to warm soil; choose heat-tolerant varieties like ‘Celebrity’ or ‘Solar Fire’ |
| Peppers (Bell & Chili) | Start indoors January–February; transplant mid-March | July–October | Need consistent warmth; avoid planting in cold, wet soil |
| Lettuce & Spinach | September–October (fall); February–March (spring) | November–December; April–May | Plant in partial shade during summer heat; use row covers in early spring |
| Herbs (Basil, Cilantro, Parsley) | Basil: March–April; Cilantro: September–October | Year-round (with care) | Basil hates cold; cilantro bolts in heat—plant in succession every 3 weeks |
| Native Wildflowers (Black-Eyed Susan, Coneflower) | October–November (dormant seeding); March–April | Blooms: Spring–Fall | Low maintenance; supports pollinators; avoid overwatering |
Spring Planting in North Texas: March to May
Spring is the busiest—and most exciting—time in my garden. After the last average frost date (around March 15 in most of North Texas), the soil begins to warm, and the growing season kicks into high gear. I always start tomatoes and peppers indoors in January, but March is when they finally go outside.
One year, I transplanted my tomato seedlings too early—right before a late freeze in early March. Over half didn’t survive. Now I wait until soil temps hit 60°F and use floating row covers just in case. For leafy greens like kale and Swiss chard, I direct-sow in late February under cold frames.
Pro tip: Add compost and slow-release fertilizer at planting time. North Texas clay soil benefits from organic matter, and it helps retain moisture during summer droughts. If you’re planting squash or cucumbers, wait until mid-April—they hate cool soil.

Summer Survival: June to August
Summer in North Texas isn’t for the faint of heart. Temperatures regularly soar past 100°F, and afternoon sun can scorch even established plants. But don’t give up—your garden can still produce.
I grow heat-loving crops like okra, sweet potatoes, and Southern peas during these months. They thrive in the heat and actually need it to set fruit. I also plant basil in partial shade to prevent bolting. Mulching with straw or shredded leaves is non-negotiable—it keeps roots cool and reduces watering needs.
Water deeply but less frequently. Early morning is best. I use drip irrigation on timers to ensure consistency. And yes, I’ve lost zucchini to squash vine borers—so now I wrap stems with aluminum foil as a preventive measure.
Believe me, a little planning goes a long way. Even in August, you can start fall crops like broccoli and carrots indoors for transplanting in September.
Fall Rewards: September to November
Fall is my favorite gardening season. The heat breaks, pests diminish, and the soil stays warm—perfect for root development. I treat this time like a second spring.
I direct-sow carrots, radishes, and beets in early September. By October, I’m planting garlic for a summer harvest next year. Cool-season herbs like cilantro and dill grow beautifully now, and they actually taste better after a light frost.
One trick I’ve learned: use shade cloth in early September to protect young seedlings from residual heat. And don’t forget cover crops like clover or rye—they improve soil health over winter.
Winter Downtime: December to February
Winter doesn’t mean your garden has to go dormant—just slower. I use cold frames and hoop houses to extend the season for spinach, kale, and lettuce. These hardy greens actually sweeten after a frost.
February is when I start my indoor seed trays. It’s also the perfect time to prune fruit trees, amend soil, and plan next year’s layout. I keep a garden journal to track what worked—and what didn’t.
Key Takeaways for North Texas Gardeners
