If you’re a Texas gardener, figuring out when can you plant potatoes in texas is the first step to a great harvest. The best time for planting depends heavily on whether you live in North, Central, or South Texas, as our state’s climate varies dramatically.
Potatoes are a cool-season crop, and timing your planting correctly is crucial to avoid our intense summer heat. Getting them in the ground at the right moment leads to healthier plants and a much better yield. Let’s break down the calendar for your specific region.
When Can You Plant Potatoes In Texas – Best Time For Planting
There are two main planting windows for potatoes in Texas: late winter for a spring harvest and late summer for a fall harvest. The goal is to have your potatoes mature during cool weather.
North Texas Planting Schedule
Winters are colder here, and the last spring frost is later. The soil needs to warm up a bit from its winter chill.
- Spring Planting: Plant from mid-February through mid-March. Wait until the soil is workable and not waterlogged.
- Fall Planting: Aim for late July to early August. This can be tricky due to heat, so extra care with water and mulch is needed.
Central Texas Planting Schedule
This region has a longer growing season and milder winters, offering more flexibility.
- Spring Planting: You can start as early as late January and continue through February.
- Fall Planting: Plant from late July through August. The fall crop often does very well here.
South Texas & Gulf Coast Planting Schedule
With very mild winters and early springs, planting happens earliest in the state.
- Spring Planting: Get your potatoes in the ground in January. Sometimes, you can even start in late December.
- Fall Planting: Plant in August. The warm fall allows for good growth.
Choosing the Right Potato Variety
Not all potatoes are created equal, especially for Texas heat. Selecting a variety suited to your planting season is key.
- Early Season (Fast Maturing): These are best for spring planting as they beat the heat. Try ‘Red Norland’, ‘Yukon Gold’, or ‘Irish Cobbler’. They mature in 70-90 days.
- Mid to Late Season: Better for fall planting where the growing season is longer and cooler. Varieties like ‘Kennebec’, ‘Russet’, and ‘Pontiac’ need 90-120 days.
Where to Get Seed Potatoes
Always use certified disease-free seed potatoes from a garden center or reputable online seller. Do not use potatoes from the grocery store, as they are often treated to prevent sprouting and can carry disease.
Step-by-Step Guide to Planting Potatoes
Follow these steps for success from planting day to harvest.
1. Preparing Seed Potatoes
About a week before planting, encourage sprouting. Place your seed potatoes in a warm, bright spot. This process is called “chitting.”
On planting day, cut larger seed potatoes into pieces. Each piece should be about the size of a golf ball and have at least 2-3 “eyes” (sprouts). Let the cut pieces dry for a day to form a callus, which helps prevent rot.
2. Preparing Your Garden Bed
Potatoes need loose, well-draining soil. They prefer slightly acidic soil with a pH between 5.0 and 6.0.
- Work the soil deeply, about 12 inches down.
- Mix in several inches of compost or well-rotted manure. Avoid fresh manure, as it can cause scab disease.
- You can plant in traditional rows, raised beds, or even large containers.
3. The Planting Process
- Dig a trench about 6 inches deep.
- Place seed potato pieces cut-side down, with the eyes facing up, every 12 inches.
- Space your trenches about 3 feet apart.
- Cover the potatoes with 4 inches of soil. Leave the trench slightly mounded.
4. Caring for Your Growing Potatoes
Consistent care is simple but important for a good crop.
- Watering: Provide 1-2 inches of water per week. Keep soil consistently moist but never soggy. Inconsistent watering leads to knobby or cracked potatoes.
- Hilling: When plants are 6-8 inches tall, mound soil around the base, covering about half the stem. Repeat this every few weeks. This protects tubers from sun (which turns them green and toxic) and encourages more potato production.
- Fertilizing: Use a balanced, low-nitrogen fertilizer at planting. To much nitrogen gives you lots of leaves but few potatoes.
Common Pests and Problems in Texas
Stay vigilant for these typical issues.
- Colorado Potato Beetle: Hand-pick the orange larvae and adults. Use row covers for prevention.
- Aphids: Spray with a strong stream of water or use insecticidal soap.
- Early Blight: Causes dark spots on leaves. Ensure good air circulation and avoid overhead watering. Rotate your crops each year.
- Heat Stress: If a late spring heatwave hits, a thick layer of straw mulch can help keep soil cool.
Harvesting and Storing Your Bounty
Knowing when and how to harvest ensures your potatoes store well.
When to Harvest
For “new” potatoes, you can gently dig around plants about 2-3 weeks after they finish flowering. For mature, storage potatoes, wait until the plant vines have completely yellowed and died back.
How to Harvest
- Use a digging fork, inserting it well away from the plant stem to avoid spearing tubers.
- Gently lift the soil and sift through with your hands to find all the potatoes.
- Let them cure in a dark, well-ventilated place for 1-2 weeks. This toughens the skin for storage.
Proper Storage
After curing, brush off dry soil—do not wash them. Store in a cool (45-55°F), dark, and humid place. A basement or cellar is ideal. Properly cured and stored potatoes can last for several months.
FAQ: Planting Potatoes in Texas
Can I plant potatoes in the summer in Texas?
No, it is generally not recommended. The soil is to hot, which prevents tuber formation and stresses the plants.
What if I miss the spring planting window?
Your best option is to wait for the fall planting window. Focus on preparing your bed and sourcing your seed potatoes for a late summer planting.
Can I grow potatoes in a container?
Absolutely. Use a large container (at least 10-15 gallons) with excellent drainage. Follow the same planting and hilling process, adding soil as the plants grow.
Why are my potato leaves turning yellow?
Late-season yellowing is normal as plants mature. Yellowing early in the season can signal overwatering, disease, or a nutrient deficiency.
How often should I fertilize my potato plants?
A light feeding at planting and another when you start hilling is usually sufficient. Avoid high-nitrogen fertilizers which promote vine over tuber growth.
By following this regional schedule and tips, you can enjoy the satisfaction of digging up your own homegrown potatoes. The key is respecting the cool-season nature of the plant and working with, not against, the Texas climate. With a little planning, you’ll have a succesful harvest.
