Vegetables to Plant in March: My Top Picks
Tomatoes: The Star of Spring
I’ve grown everything from cherry tomatoes to beefsteaks, and March is the sweet spot for transplanting in North Texas. I start my seedlings indoors in February, then harden them off in early March. By mid-month, when soil temps hit 60°F, they go into the ground. Pro tip: Add a handful of compost and a slow-release fertilizer at planting time. I’ve noticed my plants produce earlier and resist disease better when I do this.
Peppers: Heat with a Side of Flavor
Whether you love sweet bells or fiery jalapeños, peppers thrive when planted in March. I’ve learned the hard way that rushing them out too early leads to stunted growth. Wait until nighttime temps stay above 50°F. I use black plastic mulch to warm the soil and row covers on chilly nights.

Leafy Greens: Cool-Season Champions
Lettuce, spinach, and kale are still great March plantings, especially if you choose heat-resistant varieties. I plant them in partial shade now to prevent bolting when temps rise. Succession planting every two weeks keeps my salads fresh all spring. Honestly, there’s nothing like harvesting your own buttercrunch lettuce on a Saturday morning.
Flowers & Herbs: Adding Color and Scent
Marigolds: More Than Just Pretty
I plant marigolds not just for their bright blooms, but because they naturally repel nematodes and other pests. I scatter them around my tomato beds—believe me, it works. They’re also super easy: just toss the seeds in the soil and water lightly. In a few weeks, you’ll have a cheerful, low-maintenance border.
Basil & Cilantro: Kitchen Essentials
March is perfect for starting basil from seed or transplant. It loves the warming soil and full sun. Cilantro, on the other hand, prefers cooler temps, so I plant it in a shadier spot or use shade cloth as it gets hotter. I’ve found that pinching basil tips encourages bushier growth—great for pesto lovers like me.
Helpful Notes & Expert Advice
- Frost Watch: North Texas can still see late frosts in early March. Always check your local frost dates and be ready to cover tender plants.
- Soil Prep: Amend your beds with compost before planting. Our clay-heavy soil benefits from organic matter to improve drainage.
- Water Wisely: March rains help, but don’t rely on them. Water deeply 1–2 times per week, especially for newly planted seedlings.
- Mulch Matters: A 2-inch layer of straw or wood chips keeps weeds down and moisture in.
Key Takeaways
- March is ideal for planting warm-season veggies like tomatoes, peppers, and cucumbers in North Texas.
- Cool-season crops like lettuce and radishes can still be sown early in the month.
- Always harden off transplants and protect from unexpected frosts.
- Use companion planting (like marigolds with tomatoes) to boost garden health.
FAQ
Can I plant tomatoes in March in North Texas?
Yes! Mid-to-late March is the best time to transplant tomatoes after the last frost risk has passed. Just make sure soil temperatures are above 60°F.
What herbs can I plant in March?
Basil, cilantro, parsley, and dill are all great March plantings. Basil prefers full sun, while cilantro does better in partial shade as temps rise.

It depends. Warm-season crops like tomatoes and peppers should be transplanted from indoor starts. Cool-season greens and root vegetables like carrots and radishes do best when direct-sown.
