How Do You Grow Potatoes? A Simple Guide
Learn how to grow potatoes successfully in your garden or containers. This guide covers everything from chitting seed potatoes to harvesting a bountiful crop at home.
Quick Summary
Growing potatoes is a rewarding experience that yields delicious results, whether you have a large garden or just a small patio. You can easily cultivate them from special "seed potatoes" in various settings, including garden beds, containers, or even grow bags.

🛒 What You Need
- Certified seed potatoes
- Well-draining soil
- Shovel or trowel
- Garden space, large containers (10-15 gallon), grow bags, or buckets
- Organic compost or aged manure
- Water source
📋 Steps
Prepare Your Seed Potatoes (Chitting)
Before planting, it's beneficial to "chit" your seed potatoes. This involves allowing them to sprout indoors for 2-4 weeks. Place them in a cool, bright spot (not direct sun), such as a windowsill or garage. This process encourages stronger, earlier growth once planted, giving your plants a head start.
Choose Your Growing Method and Location
Decide whether you'll be planting directly in a garden bed or using containers. For garden beds, select a sunny spot with at least 6-8 hours of direct sunlight daily. If using containers, choose large pots, grow bags, or buckets (at least 10-15 gallons) with drainage holes, as potatoes need ample space for tuber development.
Prepare the Soil
Potatoes thrive in loose, well-draining, slightly acidic soil rich in organic matter. Amend your garden soil with 2-4 inches of compost or aged manure, mixing it thoroughly to a depth of 8-12 inches. For containers, use a high-quality potting mix blended with compost to ensure good drainage and fertility.

Plant the Seed Potatoes
Cut larger seed potatoes into pieces, ensuring each piece has at least one or two "eyes" (sprouts). Let the cut pieces dry for a day or two to form a protective callus. Plant these pieces or whole small seed potatoes 4-6 inches deep and 10-12 inches apart in rows 2-3 feet apart, or 2-3 per large container.
Practice Hilling (Mounding Soil)
As your potato plants grow to about 6-8 inches tall, begin "hilling." This involves mounding soil or compost around the base of the plant, covering the lower leaves. Repeat this process every 2-3 weeks as the plants grow, ensuring that no tubers are exposed to sunlight, which turns them green and toxic.
Water and Fertilize Regularly
Potatoes need consistent moisture, especially during flowering and tuber development. Water deeply when the top inch of soil feels dry, aiming for about 1-2 inches of water per week. Avoid overwatering, which can lead to rot. A balanced organic fertilizer can be applied when plants are 6-8 inches tall and again when they begin to flower.
Harvest Your Crop
“New" potatoes can be gently harvested when plants begin to flower, typically 7-10 weeks after planting. For mature potatoes, wait until the foliage has completely yellowed and died back, usually 12-16 weeks after planting. Carefully dig around the plant with a pitchfork, being careful not to pierce the tubers, and allow them to cure in a cool, dark place for a few days before storing.
💡 Tips & Tricks
- Ensure your potato plants receive at least 6-8 hours of direct sunlight daily for optimal growth and tuber development.
- Rotate your potato crops each year to a different part of the garden to help prevent soil-borne diseases and pests.
- Use straw or mulch around the base of plants after hilling to retain moisture, suppress weeds, and regulate soil temperature.

⚠️ Warnings
- ⚠️ Do not consume any potato tubers that have turned green, as this indicates the presence of solanine, a toxic compound. Cut off and discard any green parts, or discard the entire potato if widely green.

❓ Frequently Asked Questions
How do you grow potatoes?
You grow potatoes by planting certified seed potatoes in well-draining soil in a sunny location. Key steps include preparing the seed potatoes, regular watering, and mounding soil around the growing plants (hilling) to protect developing tubers from sunlight.
How to grow potatoes from potatoes?
To grow potatoes from potatoes, you'll need special "seed potatoes," which are disease-free tubers specifically for planting. You can cut larger seed potatoes into pieces, ensuring each piece has at least one or two "eyes" (sprouts), and then plant these pieces directly into the soil.
How to grow potatoes in a container?
To grow potatoes in a container, choose a large pot, grow bag, or bucket (at least 10-15 gallons) with good drainage. Fill the bottom with 4-6 inches of potting mix, plant your seed potatoes, and then progressively add more soil or compost as the plant grows (hilling) until the container is full.
How to grow potatoes from eyes?
Growing potatoes from eyes involves cutting a seed potato into pieces, each containing at least one or two prominent "eyes" or sprouts. These eyes are the points from which new potato plants will emerge. Allow the cut pieces to dry for a day or two before planting to prevent rot.
When is the best time to plant potatoes?
The best time to plant potatoes is typically in early spring, about 2-4 weeks before your region's last expected frost date, once the soil has warmed up and is workable. This allows them to establish before the peak heat of summer.
How long does it take to grow potatoes?
Potatoes generally take between 70 to 120 days to mature, depending on the variety. "New" potatoes can be harvested earlier, around 7-10 weeks after planting, while full-sized tubers require the plant's foliage to die back, usually 12-16 weeks.
What kind of soil do potatoes prefer?
Potatoes prefer loose, well-draining, and slightly acidic soil with a pH between 5.0 and 6.0. They thrive in soil rich in organic matter, so amending your garden bed or potting mix with compost or aged manure is highly beneficial.
