When to Plant Sweet Potatoes in Texas  

The best time to plant sweet potatoes in Texas depends mainly on soil temperature and frost dates. Sweet potatoes thrive in warm conditions. You’ll want to plant them after the last frost in mid-April to mid-May when the soil temperature consistently reaches 65°F or more.  

Key Tips for Planting Sweet Potatoes in Texas  

1. Check the Frost Dates  

Avoid planting too early when frost can damage your crop. Wait for the last spring frost before planting.  

2. Choose the Right Spot  

Sweet potatoes love sunlight. Pick a location that receives at least 6 hours of direct sunlight every day.  

3. Prepare the Soil  

Sweet potatoes grow best in well-drained, sandy soil. If you have clay-rich soil, consider using raised beds or adding compost for better drainage.  

4. Planting Instructions  

• Use sweet potato slips (cuttings from a mature sweet potato).  
• Plant each slip 2–3 inches deep, leaving the leaves above the ground.  
• Space slips 12–18 inches apart with rows at least 3 feet apart to allow room for growth.  

5. Water and Maintenance  

Water well after planting and keep the soil consistently moist but not waterlogged.  

When to Plant Sweet Potatoes in Houston  

Houston’s climate is warm enough to allow for a slightly extended planting season. Here, sweet potatoes can be planted as early as late April and as late as mid-August.  

Houston-Specific Tips  

• Wait for Consistently Warm Soil: Ensure the soil temperature stays above 65°F. Be aware that anything below 55°F can harm your crop.  
• Prepare Raised Beds for Clay Soil: Houston’s soil often contains clay, so raised beds 10 inches high work well to improve drainage.  
• Mulch for Better Results: Use native mulch or hay to retain moisture and regulate soil temperature.  
• Best Varieties to Grow: Consider popular sweet potato varieties like Beauregard, Centennial, Jewell, and Vardaman for excellent yields.  

Harvest your Houston-grown sweet potatoes in late November before the soil cools down too much.  

When to Plant Sweet Potatoes in South Texas  

South Texas residents have an earlier planting window for sweet potatoes, starting in March or early April. The region’s warm weather allows for an extended growing season, but timing is key to avoid frost damage.  

Tips for Planting in South Texas  

1. Plant 3–4 Weeks After the Last Frost: This ensures the risk of frost has passed and the soil is warm enough for sweet potatoes to thrive.  
2. Protect Young Plants: Late-season frosts or cooler nights can damage young plants. Cover them with row covers or milk jugs turned into mini greenhouses during cold nights.  
3. Pick the Right Type of Bed: Raised beds are ideal for South Texas conditions, as they allow water to drain correctly in areas prone to heavy spring rain.  

Sweet potatoes grow exceptionally well in South Texas, thanks to their love for heat and sunshine, but giving them a little extra care early on in the season will ensure a healthy crop.  

What is the Life Cycle of a Sweet Potato Plant?  

To grow healthy sweet potatoes, it is essential to understand their life cycle. Sweet potatoes generally take between 3.5 to 7 months to produce, depending on the variety and growing conditions.  

The Three Phases of Growth  

1. Planting to Tubers Formation (40–60 Days): During this phase, the slips establish themselves in the soil, and tubers begin to form.  
2. Tubers to Maximum Leaf Growth (60–120 Days): The plant’s leaves will develop fully, allowing photosynthesis to power root tuber enlargement.  
3. Harvest Phase: The final stage occurs when the tubers reach maturity and are ready for harvesting.  

By understanding these stages, gardeners can time their planting and harvesting schedules more effectively.  

Can You Plant Sweet Potatoes in the Fall?  

Short answer—no. Sweet potatoes are a warm-season crop that thrives in the heat of spring and summer. Since they are highly frost-sensitive, planting them in the fall puts them at risk of failing to mature before the first winter frost.  

Instead, aim to plant sweet potatoes after the last frost in spring, ensuring the soil is warm enough. The ideal planting window in Texas spans from March to August, depending on the region.  

Key Points to Keep in Mind About Planting Sweet Potatoes  

• Sweet potatoes cannot tolerate temperatures below 55°F. Always wait until the soil warms up.  
• They require loose, well-drained soil and consistent moisture to grow properly.  
• Sweet potatoes are heat-loving crops that thrive in Texas’s long summers.
