How Do You Plant Potatoes? A Beginner's Guide
Learn how to plant potatoes in your garden or containers for a bountiful harvest. This guide covers everything from preparing seed potatoes to harvesting, perfect for home growers.
Quick Summary
Planting potatoes involves preparing 'seed potatoes' with 'eyes,' choosing a sunny location with well-drained soil, and burying them at the correct depth. With proper care, including consistent watering and hilling, you can enjoy a fresh, abundant harvest from your own garden or containers.

🛒 What You Need
- Certified seed potatoes
- Shovel or garden trowel
- Well-drained soil or potting mix
- Compost or well-rotted manure
- Watering can or hose
- Large grow bags or containers (optional)
📋 Steps
1. Prepare Your Seed Potatoes
Begin with certified disease-free seed potatoes. If they are large, cut them into pieces, ensuring each piece has at least one or two 'eyes' (sprouts) and is about 1.5 to 2 ounces in weight. Allow the cut pieces to 'cure' for 1-2 days in a warm, humid spot so the cut surfaces form a protective skin, which helps prevent rot.
2. Choose Your Planting Location
Potatoes thrive in full sun, meaning at least 6-8 hours of direct sunlight per day. Select a spot in your garden that receives ample light and has good air circulation. If planting in containers, ensure they are large enough – at least 15-gallon capacity for grow bags or similar sized pots.
3. Prepare the Soil
Potatoes prefer loose, well-drained, slightly acidic soil (pH 5.0-6.0) rich in organic matter. Amend your garden soil with 2-4 inches of compost or well-rotted manure, digging it in to a depth of about 8-12 inches. This improves drainage, aeration, and provides essential nutrients for strong growth.

4. Dig Trenches or Holes
For garden planting, dig trenches about 6-8 inches deep and 12-18 inches wide. Space these trenches 2-3 feet apart to allow for hilling and good air circulation. If planting in individual holes, make them 6-8 inches deep and about 12 inches apart.
5. Plant the Seed Potatoes
Place your prepared seed potato pieces into the trenches or holes with the cut side down and the 'eyes' facing upwards. Space individual pieces about 10-12 inches apart within the trenches. This spacing gives each plant enough room to develop a good root system and produce tubers.
6. Cover and Water
Gently cover the seed potatoes with about 3-4 inches of loose soil. Avoid burying them too deeply initially. After covering, water the area thoroughly but gently to settle the soil around the seed potatoes. Consistent moisture is crucial for germination and early growth.
7. Hill Your Potatoes as They Grow
Once the potato plants emerge and reach about 6-8 inches tall, begin 'hilling' them. This involves mounding additional soil, compost, or straw around the base of the plants, covering all but the top few inches of foliage. Repeat this process every few weeks as the plants grow, which protects developing tubers from sunlight (preventing greening) and encourages more potatoes to form along the buried stem.
💡 Tips & Tricks
- Rotate Crops Annually: To prevent disease buildup in the soil, avoid planting potatoes in the same spot for at least 3-4 years.
- Consistent Moisture is Key: Potatoes need steady moisture, especially during flowering and tuber development. Aim for 1-2 inches of water per week, either from rain or irrigation.
- Mulch for Moisture and Weed Control: Apply a layer of straw or other organic mulch around your potato plants to help retain soil moisture, suppress weeds, and keep soil temperatures even.

⚠️ Warnings
- ⚠️ Do Not Plant Store-Bought Potatoes: Supermarket potatoes may be treated with sprout inhibitors and can carry diseases that could infect your garden soil. Always use certified seed potatoes.
- ⚠️ Green Potatoes Are Toxic: Tubers exposed to sunlight turn green and produce solanine, a toxic compound. Always hill your potatoes to keep them covered, and discard any green parts of harvested potatoes.

❓ Frequently Asked Questions
How do you plant potatoes at home?
To plant potatoes at home, start with certified seed potatoes, either whole or cut into pieces with 'eyes.' Plant them in well-drained, sunny soil or large containers, burying them 6-8 inches deep. Ensure consistent watering and 'hill' the plants as they grow to encourage tuber formation.
What's the best way to plant potatoes in bags or containers?
For bags or containers, choose a minimum 15-gallon fabric grow bag or large pot. Fill the bottom with 4-6 inches of good potting mix, place 2-3 seed potato pieces, and cover with 3-4 inches of mix. As the plant grows, continue to add more potting mix or compost, leaving only the top leaves exposed, until the container is full.
Can I plant red potatoes the same way as other varieties?
Yes, red potatoes, like 'Red Norland' or 'Red Pontiac,' are planted using the exact same methods as white or yellow varieties. Prepare your red seed potatoes, choose a sunny location, amend the soil, and follow the standard planting, watering, and hilling steps for a successful harvest.
When is the best time to plant potatoes?
The ideal time to plant potatoes is in early spring, about 2-4 weeks before the last expected frost date, once the soil has warmed to at least 45°F (7°C). In warmer climates, you might even be able to plant a second crop in late summer for a fall harvest.
How deep should you plant seed potatoes?
Initially, plant seed potatoes about 6-8 inches deep in trenches or individual holes. As the plants grow, you will gradually add more soil or compost around them through a process called 'hilling,' eventually burying most of the stem to encourage more tubers to form.
How long does it take for potatoes to grow?
Potatoes typically take 70 to 120 days to mature, depending on the variety. Early-season varieties are ready in about 70-90 days, while mid-season and late-season varieties can take 90-120 days or more. You can usually harvest 'new potatoes' earlier for a smaller yield.
What does 'hilling' potatoes mean and why is it important?
Hilling is the process of mounding soil, compost, or straw around the base of potato plants as they grow. This practice is crucial because it protects developing tubers from sunlight, which prevents them from turning green and toxic, and it also encourages the plant to produce more potatoes along the buried stem.
