How to Grow Potatoes in Pots

To grow potatoes in pots, plant two to three seed potatoes in a container of at least 10 gallons, starting with 4 to 6 inches of soil, then hill more soil up around the stems as they grow until the pot is nearly full. Keep the mix consistently moist, feed every two to three weeks, place the container in full sun, and harvest when the foliage yellows. Container potatoes are ideal for patios, balconies and short-season climates where the soil warms faster in a pot than in the ground.

Growing in containers gives you clean, easy harvests — you just tip the pot out — and sidesteps soil pests and diseases. The tradeoff is that pots dry out fast and yields per container are modest, so the technique rewards attention to watering and hilling. Here is the full method.

Choosing the right container

Depth is the priority because potatoes form tubers along the buried portion of the stem, so the more stem you can hill, the more room for tubers.

Whatever you use must have drainage holes — waterlogged soil rots seed potatoes and tubers. Fabric grow bags are popular because they drain and air-prune roots naturally; a five-gallon bucket works if you drill several holes in the base. Dark containers warm the soil faster in cool climates, which is one of the real advantages of container growing over open ground for early crops.

Soil mix and drainage

Fill with a light, free-draining medium: a quality potting mix blended roughly half-and-half with compost gives fertility plus drainage. Do not use heavy garden soil in pots — it compacts, holds water and suffocates the tubers. A slightly acidic mix (pH 5.0 to 6.0) also helps suppress scab, the rough skin blemish common in alkaline soils. Adding a handful of perlite improves drainage in bottom-heavy mixes.

Preparing and planting seed potatoes

Use certified seed potatoes, not grocery-store tubers, which may carry disease and sprout inhibitors. Chitting (pre-sprouting) gives a head start — see the method in when to plant potatoes.

1. Add 4 to 6 inches of mix to the bottom of the container.
2. Set two to three seed potatoes on the surface, sprouts facing up, spaced evenly. Cut large tubers into pieces with at least two eyes each and let the cut faces cure for a day before planting.
3. Cover with 3 to 4 inches of mix and water gently to settle it.
4. Place in full sun, 6 to 8 hours minimum. Timing follows the same soil-temperature rule as ground planting: 45 to 50°F, though pots warm sooner.

The hilling method for potatoes in pots

This is the step that separates a good container crop from a disappointing one. Instead of hilling soil into a mound as you would in a bed, you progressively fill the container.

1. When shoots reach 6 to 8 inches above the soil, add enough mix or compost to bury the lower two-thirds, leaving the top few inches of leaves exposed.
2. Repeat every couple of weeks as the shoots grow, until the container is filled to within an inch or two of the rim.
3. Stop hilling once the pot is full, then let the plant grow, flower and eventually die back.

Each layer of buried stem produces new tubers, so diligent hilling directly increases yield. Never let developing tubers reach the surface and turn green — green potatoes contain solanine and should not be eaten.

Watering and feeding potatoes in pots

Containers are unforgiving about water. In summer heat a full potato pot can need water daily; check by pushing a finger 2 inches into the mix and watering whenever it feels dry. Aim for consistently moist, never waterlogged — swings between dry and soaked cause hollow, cracked or knobbly tubers. Watering deeply until it runs from the drainage holes is the reliable approach; our full guidance is in how often to water potatoes.

Potatoes in pots exhaust their mix quickly, so feed every two to three weeks once shoots are established, using a fertilizer that leans toward potassium to favor tubers over foliage. Owners consistently favor formulations aimed at root and tuber crops; the ranked field is in best fertilizer for potatoes, using the method in how we rank.

Best varieties for containers and expected yield

Early and second-early varieties suit containers best because they mature faster, size up in a shorter window, and let you turn a pot around for a second crop.

• Earlies (great for pots): 'Yukon Gold', 'Red Norland', 'Caribe' — ready 70 to 90 days.
• Second earlies: 'Kennebec', 'Gold Rush' — reliable and productive.
• Fingerlings: 'Russian Banana', 'French Fingerling' — excellent flavor, well suited to bags.

Expect roughly 2 to 5 pounds from a well-managed 10- to 15-gallon container. Yields per pot are lower than ground beds, so run several bags if you want a meaningful harvest.

A second crop and reusing the mix

One advantage of container growing is how easily you can stagger crops. Because pots warm faster than open ground, you can start an early batch sooner, and in zones 7 and warmer you can plant a second crop of early potatoes in midsummer for a fall harvest, lifting them before the first frost. Chit (pre-sprout) the seed potatoes first, as midsummer mix can be warm enough to slow emergence.

Do not simply replant into the same exhausted mix. After harvest, empty the container, mix the spent medium roughly half-and-half with fresh compost, and never grow potatoes in the same mix two seasons running, since soil-borne diseases and pests build up. Better still, rotate: use last year's potato mix for a light feeder like lettuce or beans, and give the potatoes a fresh batch. This simple rotation keeps container disease pressure low without the space a garden rotation requires.

Harvesting and container problems

For new potatoes, harvest a few weeks after flowering by reaching into the mix. For full-size storage potatoes, wait until the foliage yellows and dies back, stop watering for a week to firm the skins, then tip the whole container out onto a tarp and sort through the mix.
