Best Vegetables To Plant In March In Texas
This section covers the top vegetable choices for March planting across Texas. Each recommendation includes why it works, how to plant it, and care tips for success.
Warm-Season Vegetables For March
March is the perfect time to start warm-season crops that love heat. These vegetables will grow fast once the soil warms up past 60°F.
- Tomatoes: Choose heat-tolerant varieties like ‘Heatmaster’ or ‘Solar Fire’. Plant transplants after the last frost date for your area. Space them 24 inches apart in full sun.
- Peppers: Bell peppers and jalapeños do well. Start seeds indoors or buy transplants. Soil should be at least 65°F for good root growth.
- Eggplant: Varieties like ‘Black Beauty’ or ‘Ichiban’ thrive in Texas heat. Plant them in well-draining soil with plenty of compost.
- Okra: A true Texas staple. Sow seeds directly in the ground once soil hits 70°F. Okra loves heat and will produce all summer.
- Sweet Potatoes: Plant slips in March for a fall harvest. They need loose, sandy soil and full sun.
Cool-Season Vegetables That Still Work
Even though March gets warm, some cool-season crops can still be planted early in the month. They will mature before the heat becomes intense.
- Lettuce: Leaf lettuce varieties like ‘Black Seeded Simpson’ grow fast. Plant seeds every two weeks for a continuous harvest.
- Spinach: Choose heat-resistant types like ‘New Zealand’ spinach. Harvest leaves when they are young to avoid bitterness.
- Carrots: Sow seeds directly in loose soil. Varieties like ‘Danvers’ or ‘Nantes’ do well in Texas spring.
- Beets: Plant seeds 1 inch apart. They tolerate light frost and grow quickly in March’s mild weather.
- Radishes: The fastest crop you can grow. Harvest in just 25-30 days. Plant them in rows and thin to 2 inches apart.
Legumes And Vining Crops
Beans and peas are excellent for March planting. They fix nitrogen in the soil and produce abundantly.
- Snap Beans: Bush beans like ‘Provider’ or ‘Contender’ are easy. Plant seeds 1 inch deep after soil warms.
- Pole Beans: Use a trellis for varieties like ‘Kentucky Wonder’. They need support and consistent watering.
- Southern Peas: Also called cowpeas, they love Texas heat. Plant them in late March for summer harvest.
- Cucumbers: Start seeds indoors or plant directly. Varieties like ‘Straight Eight’ or ‘Marketmore’ are reliable.
- Squash: Yellow squash and zucchini grow fast. Plant seeds in hills spaced 3 feet apart.
Herbs And Greens For March
Herbs are a great addition to any Texas garden. They are easy to grow and add flavor to your meals.
- Basil: Plant after the last frost. Varieties like ‘Sweet Basil’ or ‘Genovese’ thrive in heat.
- Cilantro: Sow seeds directly. It bolts quickly in heat, so plant in partial shade.
- Dill: Plant seeds in well-drained soil. It attracts beneficial insects to your garden.
- Swiss Chard: A colorful green that tolerates heat. Harvest outer leaves regularly for continuous growth.
- Kale: Choose ‘Lacinato’ or ‘Red Russian’ for heat tolerance. Plant in early March for best results.
Regional Considerations For Texas
Texas is huge, with different climates across the state. Your March planting plan should match your region’s conditions.

- Start seeds indoors for eggplant and okra.
- Direct sow beans and squash in late March.
- Keep an eye on soil temperature with a thermometer.
Central Texas (Austin, San Antonio, Waco)
Central Texas has mild winters and early springs. March is prime planting time. Soil warms quickly, so you can start most crops by early March.
- Plant tomatoes, peppers, and eggplant in early March.
- Sow okra and sweet potatoes by mid-March.
- Direct sow beans, cucumbers, and squash.
- Use mulch to retain moisture as temperatures rise.
South Texas (Houston, Corpus Christi, Brownsville)
South Texas is already warm in March. You can plant heat-loving crops directly. Focus on varieties that handle humidity and heat stress.
- Plant okra, sweet potatoes, and southern peas.
- Choose disease-resistant tomato varieties.
- Grow peppers and eggplant without worry of frost.
- Water deeply to combat the heat.
West Texas (El Paso, Midland, Lubbock)
West Texas has dry conditions and large temperature swings. March can be windy and cool at night. Use windbreaks and consistent watering.
- Plant cool-season crops early in March.
- Wait until late March for warm-season vegetables.
- Use drip irrigation to save water.
- Choose drought-tolerant varieties like ‘Texas Pink’ tomato.
Step-By-Step March Planting Guide
Follow these steps to ensure your March garden succeeds in Texas. Each step is simple and actionable.
- Test your soil: Use a home test kit to check pH and nutrients. Texas soil is often alkaline, so add sulfur if needed.
- Prepare the bed: Remove weeds and add 2-3 inches of compost. Till the soil to a depth of 8 inches.
- Check frost dates: Look up your area’s last frost date. Plant tender crops after that date.
- Start seeds indoors: For slow-growing crops like tomatoes and peppers, start seeds 6-8 weeks before planting.
- Harden off transplants: Gradually expose seedlings to outdoor conditions over a week.
- Plant at the right depth: Follow seed packet instructions. Most seeds need to be planted 2-3 times their diameter deep.
- Water thoroughly: After planting, water deeply to settle the soil. Keep the soil moist but not soggy.
- Mulch around plants: Use straw or wood chips to retain moisture and regulate soil temperature.
- Monitor for pests: Watch for aphids, cutworms, and squash bugs. Use organic controls like neem oil.
- Fertilize lightly: Apply a balanced fertilizer after plants have a few true leaves. Avoid over-fertilizing.
Common Mistakes To Avoid
Texas gardeners often make these errors in March. Avoid them for a better harvest.
- Planting too early: Warm-season crops can be killed by a late frost. Always check the forecast.
- Overwatering: March can be rainy in some parts of Texas. Let the soil dry slightly between waterings.
- Ignoring soil temperature: Seeds won’t germinate in cold soil. Use a soil thermometer to be sure.
- Planting too deep: Small seeds like lettuce need light to germinate. Press them gently into the soil.
- Not thinning seedlings: Crowded plants compete for nutrients. Thin them to the recommended spacing.
- Forgetting to harden off: Transplants need time to adjust. Skip this step and they may wilt or die.
