Figuring out when to plant potatoes in Texas is the first step to a great harvest. The timing varies a lot across the state’s different climate zones, so getting it right is key for a healthy crop.
Texas is big, and its planting windows are spread out. Planting at the correct time helps your potatoes avoid extreme heat and frost, leading to better yields. This guide will break down the optimal schedule for your specific area.
When to Plant Potatoes in Texas
The core rule for Texas is to plant your potatoes so they mature in the cool weather of spring or fall. Potatoes are a cool-season crop, and they don’t like our scorching summer heat. For most gardeners, this means two main planting seasons: late winter for a spring harvest and late summer for a fall harvest.
Your specific dates depend entirely on where you live. Texas is generally divided into three broad gardening regions: North Texas, Central Texas, and South Texas. Each has its own calendar.
North Texas Planting Schedule
This region includes cities like Dallas, Fort Worth, Amarillo, and Lubbock. Winters are colder here, and the last spring frost comes later.
For a spring crop, your planting window is from mid-February to early March. You want to get them in the ground 2-3 weeks before your last average frost date. The soil should be workable and not waterlogged.
For a fall crop, timing is trickier. You need to count backwards from your first average fall frost. Plant your potatoes about 110-120 days before that first frost. This usually means a planting date in late July to early August. The challenge here is the summer heat, so you may need to provide some afternoon shade for young plants.
Central Texas Planting Schedule
This area covers Austin, San Antonio, Waco, and the Hill Country. It has a longer growing season than the north.
Spring planting happens earlier here. You can usually plant from late January through mid-February. The mild winters allow for an early start, giving potatoes time to grow before the summer heat intensifies.
Fall planting is often more successful and less rushed than in the north. Aim to plant from late August to early September. This gives the potatoes a long, cool season to develop excellent flavor and texture.
South Texas & Coastal Planting Schedule
This region includes Houston, Corpus Christi, the Rio Grande Valley, and the Gulf Coast. Winters are very mild, and summers are long and hot.
Here, you primarily grow potatoes in the fall and winter for a spring harvest. Your main planting window is from September to January. Many gardeners have great success with planting around October or November.
A very early spring planting in January is possible, but the crop must be harvested before the intense May heat arrives. Fall is generally the preferred and more reliable season in the south.
How to Know Your Exact Planting Date
While these regional guides are helpful, you can pinpoint your date more precisely. Follow these two steps:
1. Find your average last spring frost date and first fall frost date. Your local county extension office is the best resource for this.
2. For spring planting, plant 2-3 weeks before your last frost date.
3. For fall planting, plant 110-120 days before your first fall frost date.
Choosing the Right Potato Variety for Texas
Timing isn’t everything; variety matters too. Some potatoes handle heat and Texas conditions better than others. Look for varieties with shorter “days to maturity” for fall planting.
Good red varieties for Texas include:
* Red LaSoda (excellent heat tolerance)
* Pontiac
* Norland
Reliable white/yellow varieties include:
* Kennebec (good disease resistance)
* Yukon Gold (popular for flavor)
* LaRouge
For russets, consider:
* Russet Norkotah (a standard in Texas)
* Texas-grown certified seed potatoes from a reputable supplier
Preparing Your Potato Seed
You should always use certified seed potatoes from a garden store, not grocery store potatoes. Grocery spuds are often treated to prevent sprouting and can carry disease. Here’s how to prepare them:
1. Chitting (Pre-sprouting): A few weeks before planting, place your seed potatoes in a cool, bright spot to encourage short, sturdy sprouts. This gives them a head start.
2. Cutting: Larger seed potatoes can be cut into pieces. Each piece must have at least 1-2 “eyes” or sprouts.
3. Curing: Let the cut pieces air dry for 1-2 days before planting. This forms a protective layer over the cut surface and prevents rot.
Step-by-Step Planting Guide
Once your date arrives and your seed is ready, follow these steps:
1. Choose a Sunny Spot: Potatoes need at least 6-8 hours of full sun.
2. Prepare the Soil: They prefer loose, well-draining soil with a slightly acidic pH (5.8-6.5). Work in several inches of compost.
3. Plant Correctly: Dig a trench or individual holes about 4-6 inches deep. Place the seed piece with the eyes facing up.
4. Space Them Out: Space pieces 10-12 inches apart in rows that are 2-3 feet apart.
5. Cover and Water: Cover with 3-4 inches of soil. Water deeply to settle the soil around the seed.
The Hilling Process
Hilling is essential for protecting the developing tubers from sunlight, which turns them green and toxic. When your plants are about 6 inches tall, mound soil around the stems, leaving just the top few leaves exposed. Repeat this process every few weeks. You can also use straw or leaves for hilling.
Caring for Your Growing Potatoes
Consistent care is simple but vital for a good harvest.
* Watering: Provide 1-2 inches of water per week. Keep soil consistently moist but never soggy. Inconsistent watering leads to misshapen tubers.
* Fertilizing: Use a balanced, low-nitrogen fertilizer at planting. Too much nitrogen encourages leafy growth instead of potatoes.
* Pests & Diseases: Watch for Colorado potato beetles and aphids. Remove by hand or use appropriate organic controls. Ensure good drainage to prevent fungal diseases like early blight.
Knowing When to Harvest
Harvest time depends on what type of potato you want.
For tender “new” potatoes, you can carefully dig around the plant about 2-3 weeks after it stops flowering.
For mature, storage potatoes, wait until the plant’s foliage has completely died back and turned yellow/brown. This is a clear sign the tubers are ready. Use a garden fork to gently lift the entire plant. Let the potatoes cure in a dry, shaded place for a week before storing them in a cool, dark location.
Frequently Asked Questions (FAQ)
Can you grow potatoes year-round in Texas?
No, you cannot grow them year-round. The summer heat is too intense. The main seasons are late winter/spring and late summer/fall, depending on your zone.
What happens if I plant potatoes too late in spring?
If planted to late, the potatoes will try to form tubers during the peak summer heat. This stresses the plant, results in very small potatoes, and can cause the plant to die prematurely.
Is it better to plant potatoes in fall or spring in Texas?
It depends on your region. In North Texas, spring is often easier. In Central and South Texas, the fall planting season is usually longer and more productive, with fewer pest problems and nicer weather for gardening.
How long does it take for potatoes to grow?
Most varieties take between 90 to 120 days from planting to full maturity for a main crop harvest. You can harvest “new” potatoes earlier, around 60-70 days.
Can I use store-bought potatoes to plant?
It is not recommended. They are often treated with a sprout inhibitor and may carry diseases that can persist in your soil for years. Certified seed potatoes are a safer, more reliable investment.
Getting your planting time right is the most important decision for Texas potato growers. By matching your planting dates to your region and providing basic care, you’ll be well on your way to digging up a succesful homegrown harvest. Remember to check with local gardeners for tips that are hyper-specific to your micro-climate, as conditions can vary even within the same city.
