Potatoes are the highest-yielding vegetable a balcony or patio gardener can grow in containers. A single 20 gallon fabric pot, planted with the right seed potatoes and hilled correctly, can produce 6 to 12 pounds of finished potatoes in one season. After comparing the most common picks from rigid plastic to fabric to specialty stacking planters, these five stood out for depth, airflow, and harvest access.

Smart Pots 20-Gallon Fabric - Best Overall
Check current price on Amazon →
The Smart Pots 20-gallon fabric pot is the segment standard for container potatoes. Twenty gallons of soil volume supports 4 to 6 seed potatoes with room for progressive hilling, the felt fabric walls air-prune feeder roots, and the breathable construction prevents the waterlogged anaerobic soil that triggers tuber rot in rigid containers.
The reinforced handles on the larger sizes handle the 80 plus pounds of wet soil when fully loaded. Harvest is as simple as cutting the side seam or tipping the bag onto a tarp; there is no digging required. Trade-off: fabric dries faster than rigid plastic, so daily summer watering is standard. For first-time container potato growers, this is the pick that delivers a meaningful harvest from a single bag.
Vivosun 5-Pack Tall Smart Pots - Best Value Pack
Check current price on Amazon →
The Vivosun 5-pack of 7-gallon tall smart pots distributes the crop across multiple containers rather than concentrating it in one. Five 7-gallon pots produce roughly the same total yield as one 25-gallon pot, with the practical advantage that varietal trials, succession plantings, and disease risk are spread across five separate containers.
The taller-than-wide proportion is the right shape for progressive hilling. Trade-off: five pots take more total patio space than one large one, and each pot needs its own watering schedule. Best for gardeners who want to grow multiple varieties (a fingerling, a russet, a red) in the same season without dedicating a single large container to one type, or who want to rotate plantings every few weeks for a longer harvest window.
Garden Stacker Potato Planter - Best Stackable
Check current price on Amazon →
The Garden Stacker potato planter is a rigid plastic system with removable stacking tiers that allow access to the lower layers without disturbing the upper plants. Lift a side panel to harvest a few new potatoes mid-season, then replace it to let the rest of the crop keep developing. The total volume is around 15 gallons across the stacked tiers.
The rigid plastic holds moisture better than fabric, which reduces watering frequency. Trade-off: rigid plastic does not air-prune roots, so the harvest leans heavier and watery rather than the firmer textures fabric produces. The stacker concept also overpromises; potatoes form along the buried stem in standard fashion regardless of the tier system. Best for gardeners who want clean, visible access to the crop mid-season and prefer a tidy rigid container on the patio.
Bloem Modica 14" - Best Decorative
Check current price on Amazon →
The Bloem Modica 14 inch is the right pick for gardeners who want the option to grow potatoes without the patio looking like a vegetable production line. The 14 inch resin pot holds roughly 8 gallons of soil, which supports 2 to 3 seed potatoes with progressive hilling, and the matte exterior matches typical patio furniture and decorative planters.
The integrated drainage and saucer simplify watering on a finished deck where runoff is a concern. Trade-off: 8 gallons is the bottom of the productive range; total yield per pot is 2 to 4 pounds rather than the 6 to 12 of a fabric 20-gallon. Best for mixed-use patios where the container does double duty as a decorative element and a working vegetable planter, or for growing a smaller variety like fingerlings.
Geopot 25 Gallon - Best Large Yield
Check current price on Amazon →
The Geopot 25 gallon is the top of the practical range for container potatoes. Twenty-five gallons supports 6 to 8 seed potatoes with full hilling, the heavy-duty geofabric resists puncture and tearing through multiple seasons, and the depth allows the longest possible buried stem for maximum tuber set.
A single 25 gallon Geopot is capable of producing 10 to 15 pounds of finished potatoes in a strong season, which is enough to actually contribute to a household pantry rather than a single meal. Trade-off: the fully loaded pot weighs over 100 pounds and is not realistically portable. Best for serious patio and small-yard growers who have a sunny permanent location and want maximum yield from a single container investment.
How to choose a potato container
Volume drives yield. Each plant wants 2.5 to 3 gallons of soil. A 20 gallon pot is the practical sweet spot for most households.
Depth over width. Potatoes form along the buried stem when hilled. Tall narrow pots yield more per square foot than wide shallow ones.
Fabric beats rigid. Air-pruned roots, breathable walls, and easy tip-out harvest all favor fabric pots over rigid plastic for potatoes specifically.
Plan for hilling. Start with 4 to 6 inches of soil and add more progressively as the stem grows. A pot that cannot be filled in stages does not produce hilled-crop yield.
Best varieties for container growing
Determinate (early-season) varieties set their tubers in a concentrated layer and are the best match for containers. Yukon Gold, Red Norland, and Russet Norkotah all produce a strong container yield in 70 to 90 days and do not require the multiple hilling layers that indeterminate (late-season) varieties demand. Fingerling varieties like Russian Banana and Magic Molly are particularly well suited to containers because their compact tuber size avoids the misshapen growth that crowded large-tuber varieties produce.
Avoid the late-season main-crop russets sold for storage growing; they want a long season and deep in-ground beds rather than the constrained root volume of a 20 gallon pot. The seed potatoes themselves matter as much as the variety. Certified seed potatoes from a reputable supplier produce far healthier plants than grocery store potatoes, which are often treated with sprout inhibitors and may carry virus and disease from commercial fields.
Pre-sprouting (also called chitting) the seed potatoes for two to four weeks in a cool bright room before planting accelerates the first growth and adds two to three weeks to the effective season. This matters in cooler climates where the frost-free window is short. Cut larger seed potatoes into chunks with at least two eyes each, let the cut surfaces dry for 24 to 48 hours before planting, and plant 4 inches deep with eyes facing up.

Frequently asked questions
How big does a container need to be for potatoes?+
Each potato plant needs roughly 2.5 to 3 gallons of soil volume to produce a worthwhile crop. A 20 gallon container fits 4 to 6 seed potatoes comfortably, a 10 gallon container fits 2 to 3, and a 5 gallon container fits a single plant. Depth matters more than width because potatoes form along the buried stem; 14 to 18 inches of depth allows full hilling. Tall narrow planters yield more per square foot of patio than wide shallow ones.
How many potatoes can I grow in one container?+
Plan for one seed potato per 2.5 gallons of container volume. A 20 gallon fabric pot supports 4 to 6 plants, each producing 1 to 2 pounds of finished potatoes in a good season for 6 to 12 pounds total. Crowding more plants in does not increase yield; it reduces tuber size and increases disease pressure. Determinate varieties yield more in containers than indeterminate ones because they set tubers in a single concentrated layer rather than along a long stem.
Do I need to hill potatoes in a container?+
Yes, hilling is what makes container potatoes worthwhile. Start with 4 to 6 inches of soil at the bottom, plant the seed potato, and as the stem grows add more soil to bury all but the top 2 to 3 inches of foliage. Repeat every 2 to 3 weeks until the container is full. Each hilling encourages additional tubers to form along the buried stem. A 20 gallon container that is hilled three times produces roughly double the yield of one filled to the top at planting.
When are container potatoes ready to harvest?+
New potatoes can be harvested 2 to 3 weeks after the plants flower, typically 60 to 70 days after planting. Mature storage potatoes are ready when the foliage yellows and dies back, usually 90 to 120 days after planting. Stop watering once the foliage starts to die so the skins toughen. Tip the container onto a tarp to harvest; this is one of the major advantages of container growing over in-ground rows.
Can potatoes grow in a 5 gallon bucket?+
Yes, a single seed potato in a 5 gallon bucket produces 1 to 2 pounds of harvest if the bucket has drilled drainage holes and is hilled progressively. The bucket size limits yield per plant, but multiple buckets on a patio can produce a respectable total. Drill at least eight quarter-inch holes in the bottom and another four around the lower sides for drainage and air pruning. Food-grade buckets are required for any container that holds soil for food crops.
