Learn how to grow potatoes from seed the right way — with expert advice, planting tips, and answers to common questions. A must-read guide for beginners and seasoned gardeners alike!

Why Grow Your Own Potatoes?

Growing your own potatoes is easy, rewarding, and incredibly tasty. Whether you’re planting in garden rows, raised beds, or containers, potatoes are a resilient and high-yielding crop perfect for any level of gardening experience.

At Piedmont Farm and Garden, we provide top-quality, non-GMO seed potatoes and expert support to help you grow a successful harvest from planting to storage.

When to Plant Seed Potatoes

Timing is everything when it comes to planting seed potatoes. Aim to plant:

  • 4–6 weeks before the last expected frost
  • When soil temperatures reach 55–65°F
  • In loose, well-drained soil, never overly wet

No eyes yet? No problem! Place seed potatoes in a warm, dry place — like a pantry or sunny window — to encourage sprouting.

A 5-pound bag of seed potatoes typically covers a 50-foot row, making it easy to plan your garden layout.

How to Prepare and Plant Seed Potatoes

Step 1: Cut & Cure

  • Cut larger seed potatoes into 1" cubes, each with at least one eye
  • Let them dry for 24 hours to form a protective callous before planting

Step 2: Create Rows

  • Space rows 36"–42" apart for airflow and bushy growth
  • Dig shallow trenches 6–8 inches deep

Step 3: Planting

  • Place seed pieces eyes-up, 12–14 inches apart
  • Cover with 3–4 inches of soil (don’t fill the trench completely yet)
  • Apply organic fertilizer like Espoma Garden-tone over the top

Sprouts should emerge within 1–2 weeks depending on soil warmth

Hilling Potatoes

Once sprouts reach 6–8 inches tall, begin hilling:

  • Mound soil from each side of the trench toward the plant
  • Cover about halfway up the stems (but never bury the entire plant)

Repeat hilling every 1–2 weeks as the plant grows. This promotes tuber growth and prevents sunlight exposure (which causes green, inedible potatoes).

Growing Season Care

✔ Watering

  • Keep soil evenly moist, not soggy
  • 1–2 inches of water per week is ideal

✔ Mulching

  • Use mulch to retain moisture, suppress weeds, and regulate soil temperature

✔ Fertilizing

  • Apply balanced fertilizer or compost mid-season
  • Avoid high-nitrogen fertilizers, which promote leaves over tubers

✔ Pest & Disease Management

  • Watch for potato beetles, aphids, and wireworms
  • Use organic pest control or beneficial insects
  • Remove and destroy infected plants promptly if blight or rot appears

Harvesting Potatoes

Potatoes are typically ready 8–10 weeks after planting, once the vines begin to yellow and die back.

To Harvest:

  • Gently dig around the base with a spade or fork
  • Avoid bruising or cutting the tubers
  • Let tubers dry a few hours in the shade before storing

Tip: Always test a few potatoes from different spots before digging up the entire row.

Storing & Using Your Potatoes

✔ Curing

Cure harvested potatoes in a dark, warm, ventilated space for 1–2 weeks to toughen the skins for storage.

✔ Storage Conditions

  • Cool (45–55°F), dark, and humid
  • Avoid light exposure (causes greening)
  • Never refrigerate — it turns starch into sugar, affecting flavor and texture

✔ Culinary Uses

Potatoes are one of the most versatile vegetables:

  • Mashed – Creamy and comforting
  • Roasted – Crispy edges, fluffy centers
  • Baked – Perfect for stuffing or slicing
  • Fried – Homemade fries or hash browns
  • In Soups & Stews – Adds texture and richness

Frequently Asked Questions (FAQs)

Q: Can I grow potatoes in containers or raised beds?

Yes! Use a large container or 12" deep raised bed with loose soil and proper drainage. Great for small spaces.

Q: Can I plant grocery store potatoes?

Not recommended. Most are treated with sprout inhibitors and may carry diseases. Always use certified seed potatoes.

Q: How do I prevent green potatoes?

Keep tubers fully covered with soil or mulch during growth. Sunlight exposure causes greening and bitterness.

Q: How long does it take to grow potatoes?

Most varieties are ready in 90–120 days, depending on the type and weather conditions.
