How To Grow Potatoes In A Container

Growing potatoes in a container is an excellent alternative for those with limited garden space.

Container gardening provides a versatile solution for urban dwellers and anyone facing space constraints. By opting for containers, you can control growing conditions, ensuring optimal soil quality, moisture levels, and sunlight exposure.

This method also facilitates easier monitoring of pests and diseases, reducing the risk of crop damage. The compact nature of container-grown potatoes enables gardeners of all levels to enjoy the satisfaction of homegrown produce.

This hands-on experience not only fulfills adults but also offers valuable learning opportunities for children, fostering their connection with nature and teaching them essential skills about food cultivation and responsibility.

Let’s explore the art of growing potatoes in containers and discover how this method can transform even the smallest spaces into flourishing gardens brimming with flavor and nourishment.

Seed Potatoes

Certain varieties of seed potatoes thrive in container environments:

  • Yukon Gold: Medium-sized potatoes with a creamy texture and buttery flavor.
  • Red Pontiac: Red-skinned potatoes boasting smooth white flesh.
  • Fingerling: Small, finger-shaped potatoes with colorful skins and firm flesh.
  • Russet: Large, brown-skinned potatoes with starchy white flesh.
  • Adirondack Blue: Distinctive blue-skinned and blue-fleshed potatoes.

Cut seed potatoes into pieces, ensuring each has at least two eyes or growth nodes. These are vital for shoot emergence and robust growth post-planting. Allow the cut pieces to air dry for several days to form a protective callus, which helps prevent rot and disease.


Potting Mix

Choose high-quality, fast-draining soil. Mix commercial potting soil with compost in a 1:1 ratio for essential nutrients. Avoid garden soil to prevent pathogen and weed seed contamination.

Add an organic, slow-release fertilizer with a balanced ratio, such as 10-10-10 or 5-5-5, to support healthy growth. Aim for a slightly acidic pH of 5.0 to 6.0, and ensure your container receives at least 8 hours of sunlight daily.

Select a container with ample drainage holes and made from food-safe materials. Provide approximately 2.5 gallons of space per potato plant. Opt for containers between 2 and 3 feet deep to accommodate the roots adequately.

Fabric potato grow bags offer versatility and excellent drainage. Plastic buckets and bins are viable options but require drainage holes.

Avoid containers made from materials like old tires due to potential chemical contamination. Instead, consider alternatives like wooden half-barrels, plastic storage tubs, burlap sacks, or canvas tote bags.

Fill the container with 4 to 6 inches of potting soil blended with compost and fertilizer, leaving space at the top for hilling later. Space potato pieces 10 inches apart with eyes facing up, covering them with 3 to 4 inches of potting mix.

Ensure consistent watering to maintain even soil moisture throughout the growing season.

Care for Potatoes In A Container

Here are main requirements for taking care of potatoes in a container:

  • Ensure your container receives at least eight hours of full sun daily.
  • Use potting soil blended with compost and fertilizer to ensure proper drainage and nutrients.
  • Space seed potatoes about 10 inches apart and leave 4 inches of space from the sides.
  • Provide about 1 to 2 inches of water per week.
  • Add soil around them every 2 to 3 weeks to encourage tuber formation and prevent greening.



Potatoes need at least 8 hours of full sun daily. Adequate sunlight promotes photosynthesis, prevents leggy growth, and ensures healthy foliage and tuber development.

If grown in partial shade, potato plants may become leggy and produce smaller yields.



Use well-draining soil blended with compost and fertilizer. Ensure the pH of the soil falls within the range of 5.0 to 6.0, as potatoes thrive in slightly acidic conditions. This optimal pH level promotes nutrient uptake and healthy growth.



Potatoes require about 1 to 2 inches of water per week. Water them in the morning and maintain consistent soil moisture, avoiding both dryness and soggy conditions.

Test soil moisture by using your finger; if the top 1 to 2 inches feel dry, it’s time to water. Alternatively, consider installing a drip irrigation system for efficient watering.


Temperature and Humidity

Container-grown potatoes thrive in zones 3-9 and temperatures between 60-70°F (15-21°C). Moderate humidity levels are ideal, avoiding extremes that can lead to fungal diseases or poor plant health.



Once your potato plants reach approximately 6 inches in height, gently mound soil around the base of the stems to begin the hilling process. Take care not to damage the plants as you add soil. Gradually cover about one-third of the plant, including the lower leaves.

Repeat this process periodically as the plants grow, stop when the soil reaches the top of the container. Hilling encourages additional tuber formation along the buried stems, optimizing your potato harvest.



Incorporate organic, slow-release fertilizer into the potting mix to support healthy growth without the risk of burning the plants. Besides, you can use a diluted liquid fertilizer like fish emulsion applied every couple of weeks as your potatoes mature.

Pests and Diseases

Container-grown potatoes are vulnerable to pests like aphids, potato beetles, and slugs, as well as diseases like late blight, which causes black, moldy foliage. Check undersides of leaves for beetle eggs and larvae. Infestations and diseases can stunt growth and reduce yield.

Control them with organic methods like hand-picking and neem oil application. Maintaining soil drainage is vital for preventing outbreaks and ensuring a healthy harvest.

Common Problems


Overwatering or poor drainage can lead to rot, causing soggy soil and diminished plant health. Ensure proper drainage in the container and avoid overwatering. Use a well-draining potting mix and allow the soil to dry slightly between waterings.


Wilting and Poor Production

Frequent soil dryness can result in wilting and reduced potato production. Monitor soil moisture regularly and water consistently to keep the soil evenly moist. Consider adding mulch to help retain moisture.


Nutrient Deficiency

Stunted growth may occur due to nutrient deficiency. Use liquid fertilizer with each watering to provide essential nutrients to the plants. Follow the fertilizer manufacturer’s instructions for proper application.

Tuber Greening

Direct sunlight exposure on potato tubers can cause them to turn green. Make sure plants receive full sun while shielding tubers from direct sunlight using mulch or hilling up soil around the base of the plants.



Wait until the potato plants have flowered and the foliage begins to yellow and die back. This typically occurs 70-90 days after planting, depending on the variety.

Gather a garden fork or shovel and a container for collecting potatoes. Gently dig around the base of the plants, taking care not to damage the tubers. Lift the plants and shake off excess soil to reveal the potatoes.




Allow harvested potatoes to cure in a cool, dark, ventilated area for 1-2 weeks to toughen the skin. Store cured potatoes in a cool, dark place with good airflow, avoiding refrigeration.

Use breathable containers like paper bags or wooden crates, avoiding plastic. Regularly inspect stored potatoes for spoilage, removing any damaged ones promptly.


Growing potatoes in containers is a fantastic solution for those with limited gardening space. With some simple steps, anyone can enjoy the satisfaction of harvesting their own fresh, homegrown potatoes.
