Potatoes in Texas are planted in late winter for a spring harvest or late summer for a fall crop. Knowing exactly when to plant potatoes in texas is the difference between a full bin of spuds and a disappointing harvest. Texas has diverse climates, from the humid east to the arid west, so timing shifts depending on where you live. This guide walks you through the exact planting windows, soil prep, and care steps to get the best yield possible.
Potatoes are a cool-season crop, meaning they thrive when temperatures are mild. In Texas, the heat comes fast, so you have to work with two distinct planting seasons. Spring planting happens in late winter, while fall planting occurs in late summer. Both seasons have their own tricks and challenges.
Let’s break it down region by region, so you know exactly when to put those seed potatoes in the ground.
When To Plant Potatoes In Texas: Regional Breakdown
Texas is huge, spanning USDA hardiness zones 6 through 9. What works in Amarillo won’t work in Brownsville. Here’s a simple breakdown by region.
North Texas (Zones 7-8)
North Texas includes Dallas, Fort Worth, and surrounding areas. Spring planting runs from mid-February to mid-March. The soil should be workable, not frozen or waterlogged. Fall planting happens from mid-August to early September.
Key tip: Watch the last frost date, which is usually around March 15 in this region. Plant 2-4 weeks before that last frost for spring. For fall, aim for 90-120 days before the first fall frost, which hits around mid-November.
Central Texas (Zones 8-9)
Central Texas, including Austin, San Antonio, and Waco, has milder winters. Spring planting starts earlier, from late January to late February. Fall planting runs from late August to mid-September.
The soil warms faster here, so you can get a head start. But watch out for sudden warm spells in March that can stress young plants. For fall, count backward from the first frost date, usually around late November.
South Texas (Zones 9-10)
South Texas, including Houston, Corpus Christi, and the Rio Grande Valley, has a long growing season. Spring planting is best from late January to early March. Fall planting runs from September to October.
In this region, heat is the bigger enemy than cold. Potatoes stop growing when soil temps hit 85°F. So spring planting needs to happen early enough to allow harvest before May. Fall planting works well because the weather cools down.
West Texas (Zones 6-7)
West Texas, including El Paso and Lubbock, has a shorter growing season. Spring planting runs from mid-March to early April. Fall planting is tricky because of early frosts, so aim for mid-July to early August.
Irrigation is key here because the climate is dry. Plant in well-draining soil and water consistently. The first frost can come as early as mid-October, so choose short-season potato varieties.
Soil Preparation And Seed Potato Selection
Before you plant, get the soil right. Potatoes prefer loose, well-draining soil with a pH between 5.0 and 6.5. Texas clay soil can be a problem, so amend it with compost or aged manure.
How To Prepare The Soil
- Test the soil pH. Add sulfur to lower pH if needed.
- Loosen the soil to at least 12 inches deep.
- Mix in 2-4 inches of organic matter like compost.
- Remove rocks and debris that can deform tubers.
- Ensure good drainage; raised beds work well in heavy clay.
Choosing Seed Potatoes
Always use certified seed potatoes from a garden center, not grocery store potatoes. Grocery spuds are often treated to prevent sprouting. Seed potatoes are disease-free and bred for your region.
Popular varieties for Texas include:
- Red La Soda – heat-tolerant, great for South Texas.
- Kennebec – reliable for North and Central Texas.
- Yukon Gold – good for all regions.
- Russet Burbank – best for West Texas.
Cutting And Curing Seed Potatoes
- Cut seed potatoes into pieces, each with at least 2-3 eyes.
- Let the cut pieces cure for 1-2 days in a cool, dry place. This forms a protective callus.
- Plant within a week of cutting.
Step-By-Step Planting Guide For Texas
Now that you know the timing, here’s how to plant. Follow these steps for a strong start.
1. Choose The Right Location
Pick a spot with full sun, at least 6-8 hours daily. Avoid areas where tomatoes, peppers, or eggplants grew recently, as they share diseases with potatoes.
2. Dig Trenches Or Holes
Dig trenches 4-6 inches deep. Space rows 2-3 feet apart. Within each row, space seed pieces 12-15 inches apart.
3. Plant The Seed Pieces
Place each seed piece with the eyes facing up. Cover with 2-3 inches of soil. Don’t fill the trench completely yet; you’ll mound soil later as the plants grow.
4. Water Thoroughly
Water right after planting to settle the soil. Keep the soil moist but not soggy. Overwatering can rot the seed pieces.
5. Hill The Soil As Plants Grow
When the plants reach 6-8 inches tall, pull soil up around the stems, leaving only the top leaves exposed. Repeat this process every 2-3 weeks. Hilling prevents tubers from turning green and protects them from sun.
Caring For Potato Plants In Texas Heat
Texas summers are brutal. Potatoes need consistent moisture and some shade from intense heat. Here’s how to keep them healthy.
Watering Schedule
- Water deeply once or twice a week, depending on rainfall.
- Use drip irrigation or soaker hoses to avoid wetting the leaves.
- Mulch with straw or grass clippings to retain moisture and keep soil cool.
Fertilizing
Potatoes are heavy feeders. Apply a balanced fertilizer (10-10-10) at planting time. Side-dress with a low-nitrogen fertilizer when plants start flowering. Too much nitrogen leads to lush foliage but small tubers.
Pest And Disease Management
Common pests in Texas include Colorado potato beetles, aphids, and wireworms. Use insecticidal soap for aphids and hand-pick beetles. Rotate crops yearly to prevent soil-borne diseases like scab and blight.
Harvesting Potatoes In Texas
Knowing when to harvest is just as important as knowing when to plant. Potatoes are ready 90-120 days after planting, depending on the variety.
New Potatoes
For small, tender “new” potatoes, harvest about 2-3 weeks after the plants flower. Gently dig around the roots and take a few tubers, leaving the plant to keep growing.
Full-Sized Potatoes
Wait until the plant foliage turns yellow and dies back. Then stop watering for 1-2 weeks. This hardens the skins for storage. Dig carefully with a garden fork to avoid cutting the tubers.
Curing And Storing
Cure potatoes in a dark, cool place (50-60°F) with high humidity for 1-2 weeks. After curing, store them in a dark, cool spot. Don’t wash them until you’re ready to use them.
Common Mistakes Texas Gardeners Make
Even experienced gardeners slip up. Here are the most common errors and how to avoid them.
- Planting too late in spring – heat stops tuber growth.
- Planting too early in fall – hot soil rots seed pieces.
- Using grocery store potatoes – they may carry diseases.
- Overwatering – leads to rot and fungal issues.
- Not hilling – results in green, bitter potatoes.
- Skipping soil testing – leads to nutrient imbalances.

Frequently Asked Questions
Can I Plant Potatoes In Texas In The Summer?
Summer planting is not recommended because soil temperatures exceed 85°F, which stops tuber formation. Stick to spring and fall seasons.
What Is The Best Potato Variety For Texas Heat?
Red La Soda and Kennebec are top choices for heat tolerance. Yukon Gold also performs well in most regions.
How Deep Should I Plant Potatoes In Texas?
Plant seed pieces 4-6 inches deep. Cover with 2-3 inches of soil initially, then hill as plants grow.
Do I Need To Water Potatoes Every Day In Texas?
No, daily watering can cause rot. Water deeply once or twice a week, adjusting for rainfall and heat.
Can I Grow Potatoes In Containers In Texas?
Yes, containers work well, especially in small spaces. Use a 10-15 gallon pot with drainage holes and loose potting mix.
Final Tips For A Bountiful Harvest
Planting potatoes in Texas is all about timing. Get the date right, and the rest falls into place. Start with quality seed potatoes, prep your soil, and water consistently. Watch the weather and be ready to protect plants from late frosts in spring or early heat waves.
Remember that each region has its own microclimate. Talk to local gardeners or your county extension office for specific advice. Keep a garden journal to track planting dates and results year after year.
With a little planning, you can enjoy fresh, homegrown potatoes from both your spring and fall harvests. There’s nothing quite like digging up your own spuds and knowing you grew them from start to finish.
So grab your seed potatoes, check the calendar, and get planting. Your future self—and your dinner table—will thank you.
