Growing Potatoes in North Texas: The Complete Guide for Planting, Harvesting & Storing

Growing potatoes in North Texas is one of the most rewarding early‑season garden projects you can take on. Our mild winters and fast‑warming spring give you a perfect—but narrow—window to plant. With the right timing, soil prep, and variety selection, you can pull in a beautiful harvest before the summer heat shuts the plants down.

This guide covers everything you need to know: planting dates, soil prep, choosing seed potatoes, fertilizing, watering, pests, harvesting, and long‑term storage.

🗓 Best Time to Plant Potatoes in North Texas

Potatoes must be planted early, before the soil warms above 80°F.

• Ideal planting window: February 10 – March 10
• Absolute latest: March 15 (reduced yields after this)
• Fall planting: August 15 – September 10 for a second crop

Potatoes stop forming tubers once soil temps climb, so planting early is the key to success.

🥔 Choosing the Best Potato Varieties for North Texas

North Texas gardeners do best with early and mid‑season varieties that mature before the heat arrives.

Top Varieties That Thrive Here

• Red LaSoda – The classic Texas red potato; reliable and heat‑tolerant.
• Yukon Gold – Creamy, buttery, and matures early.
• Kennebec – Great all‑purpose potato with strong disease resistance.
• Red Pontiac – Fast‑growing and forgiving for beginners.
• Irish Cobbler – Excellent early variety for quick harvests.

Avoid long‑season russets—they rarely finish before the heat shuts them down.

🧱 How to Prepare Soil for Potatoes in North Texas

Potatoes love loose, fluffy, well‑drained soil. Heavy clay (which we have plenty of) must be amended.

Ideal Soil Mix

• 50% compost
• 40% raised‑bed soil or sandy loam
• 10% perlite or coarse sand

Target Soil Conditions

• pH: 5.8–6.5
• Depth: 10–12 inches of loose soil
• Drainage: Essential—wet soil causes rot

If planting in‑ground, mound the soil into 8–10 inch ridges to improve drainage.

🧪 Selecting & Preparing Seed Potatoes

Always use certified seed potatoes, not grocery store potatoes (they’re treated to prevent sprouting).

How to Prepare Seed Potatoes

• Cut large potatoes into chunks with 2–3 eyes each
• Let cut pieces dry 24 hours to callus
• Plant whole if smaller than a golf ball

This prevents rot and gives each plant a strong start.

🌱 How to Plant Potatoes in North Texas

• Planting depth: 4 inches deep
• Spacing: 10–12 inches apart
• Row spacing: 24–30 inches
• Orientation: Eyes facing upward

Cover lightly at first—more soil will be added as the plants grow.

🧺 Hilling: The Secret to Bigger Harvests

As potato plants reach 6–8 inches tall, mound soil around the stems, covering the lower leaves.

Repeat every 1–2 weeks until the hill is 10–12 inches tall.

Hilling:

• Protects tubers from sunlight
• Encourages more tuber formation
• Helps control weeds

💧 Watering Potatoes in Texas Heat

Potatoes need consistent moisture, especially during tuber formation.

• Water 2–3 times per week in spring
• Keep soil moist but never soggy
• Reduce watering once plants begin to yellow

Mulch heavily to keep soil cool and reduce evaporation.

🌿 Fertilizing Potatoes

Potatoes are moderate feeders.

Before Planting

• Mix in 2–3 inches of compost
• Add a balanced organic fertilizer (like 10‑10‑10 or Espoma Garden‑Tone)

During Growth

• Side‑dress with nitrogen once plants reach 6 inches
• Avoid over‑fertilizing—too much nitrogen = lots of leaves, few potatoes

🐛 Common Potato Pests in North Texas

Colorado Potato Beetles

• Hand‑pick adults and larvae
• Use neem oil or spinosad if needed

Aphids

• Spray with soapy water
• Encourage ladybugs

Flea Beetles

• Use row covers early in the season

Fire Ants

• Disturb hills and use mound treatments around—but not on—plants

Healthy soil and early planting reduce most pest pressure.

🌾 When & How to Harvest Potatoes

New Potatoes

• Harvest 60–70 days after planting
• Gently dig around the plant edges

Full‑Size Potatoes

• Wait until vines yellow and die back
• Stop watering 1–2 weeks before harvest
• Use a garden fork to lift from the side, not directly on top

Let potatoes cure in a shaded, ventilated area for 7–10 days.

🧊 How to Store Potatoes Long‑Term

After curing:

• Store at 45–55°F
• Keep in darkness
• Use mesh bags, crates, or paper sacks
• Never refrigerate—this converts starch to sugar

Properly stored potatoes last 2–4 months.

🥔 How to Preserve Potatoes

Freezing

• Blanch diced potatoes 3–5 minutes
• Freeze on a tray, then bag

Dehydrating

• Slice thin
• Dry until crisp
• Store in airtight jars

Canning

• Pressure‑can only (low‑acid food)
• Follow USDA guidelines

Root Cellaring

• Works well in garages or closets if temps stay cool

🌟 Final Tips for Potato Success in North Texas

• Plant early—heat is your biggest enemy
• Choose fast‑maturing varieties
• Keep soil loose and well‑drained
• Hill consistently
• Water deeply but avoid soggy soil
• Harvest before the heat of June
