When to Plant Potatoes in Texas (2026 Guide)
Growing potatoes in Texas can be an incredibly rewarding endeavor for both novice and experienced gardeners. Understanding your local climate and frost dates is crucial for a successful harvest. For those in the warmer regions, such as Zone 8b, the median last spring frost occurs on February 13, allowing for an early start to the planting season.
In contrast, gardeners in parts of Zone 7b must wait until after March 4, as that is the median last frost date in these areas. Despite the waiting period, potatoes are a highly productive crop that can yield 5–10 full-size potatoes from just one seed piece, making patience a worthwhile investment.
As you plan your potato planting schedule, it's essential to pay attention to the specific zone and its weather patterns. For example, cities like Houston and San Antonio offer different growing conditions, and knowing when to plant not only maximizes yields but also enhances the flavor and quality of your harvest.

Common Mistakes Growing Potatoes in Texas
- One common mistake in Texas gardening is failing to account for late spring frosts. Many gardeners assume the frost-free season starts earlier than it actually does, leading to the loss of seedlings planted too early.
- Ignoring soil health can be detrimental to potato cultivation. Texas soil varies significantly, with areas having clay and high alkalinity that can affect drainage and nutrient availability, leading to poor potato production.
- Texas gardeners often plant grocery store potatoes instead of certified seed potatoes. Grocery varieties may harbor diseases, ruining your crop and possibly impacting subsequent planting seasons with lingering pathogens in the soil.
- Underestimating the need for hilling is a frequent issue. As potato plants grow, proper hilling can enhance yield and help prevent tubers from greening, which is common in humid Texas conditions due to surface exposure.
- Many gardeners in Texas may delay harvesting until potatoes are fully mature, resulting in lower quality. Waiting for the tops to die back is crucial, but waiting too long may lead to pests or blight.
Frequently Asked Questions
What if I'm in a cold pocket of Texas?
If you're in a colder area, you might need to start your potatoes indoors earlier and wait longer to transplant. Monitor local frost dates closely and be ready to protect young plants from unexpected late frosts.
Can I still plant potatoes in May?
Planting in May is not ideal, especially in Zone 7a, as you risk lower yields. It's better to stick to the recommended planting windows for optimal results, which are typically before the first week of April.
Are there specific types of potatoes best for Texas?
Yes, choosing early to mid-season varieties like Yukon Gold or Red Bliss is beneficial for Texas gardeners. These types thrive in the state's varied climates and can handle the changing conditions throughout the growing season.
How often should I water my potato plants?
Water your potato plants consistently, aiming for about 1-2 inches per week. Adjust accordingly based on rainfall and temperature; ensure that the soil remains moist but not waterlogged to prevent disease.
What should I do if my potato leaves are turning yellow?
Yellowing leaves can indicate various issues, including nutrient deficiencies and pests. Check soil conditions, look for signs of pests, and ensure you're using proper fertilization to help your potato plants flourish.
