Whether you have a small balcony, patio, or just a corner of your backyard, grow bags offer a portable, low-maintenance solution for cultivating spuds. In this blog, we’ll walk you through the simple steps to grow potatoes in grow bags, share practical tips, and help you enjoy a delicious harvest. Let’s dig in!
Grow bags are fabric containers designed for gardening, offering unique advantages for growing potatoes:
Space Efficiency: Perfect for small spaces like balconies, patios, or urban gardens.
Easy Harvesting: No shovel needed—simply reach in or tip the bag to collect your potatoes.
Healthy Roots: The breathable fabric promotes air pruning, preventing root-bound plants.
Reusable and Portable: Move them to catch the sun or reuse them for multiple seasons.
With minimal setup and care, grow bags can yield a surprising amount of potatoes. Let’s get started!

1. Choose the Right Grow Bags
Opt for fabric grow bags with a capacity of 5–10 gallons (20–40 liters) for potatoes. Look for sturdy handles and good drainage holes to prevent waterlogging. You can find these at garden centers or online.
Tip: A 10-gallon bag can typically support 3–5 potato plants, depending on the variety.
2. Pick Your Potato Variety
Select seed potatoes based on your taste and climate. Popular choices include:
Yukon Gold: Buttery and great for mashing or roasting.
Russet: Perfect for baking or fries.
Fingerling: Small, flavorful, and ideal for salads.
Purchase certified disease-free seed potatoes from a nursery or garden supplier. Avoid using supermarket potatoes, as they’re often treated to prevent sprouting.
Tip: Check with local gardeners or extension services for varieties that thrive in your area.
3. Prepare the Seed Potatoes
If your seed potatoes are large, cut them into chunks, ensuring each piece has 1–2 “eyes” (the small sprouts).
Let the cut pieces sit in a cool, dry place for 1–2 days to form a callus, which helps prevent rot.
Tip: Small seed potatoes (golf ball-sized or smaller) can be planted whole.
4. Set Up the Grow Bag
Location: Place the grow bag in a spot that gets 6–8 hours of sunlight daily.
Soil Mix: Fill the bottom 4–6 inches of the bag with a mix of 60% potting soil, 30% compost, and 10% sand or perlite for drainage. Potatoes prefer slightly acidic soil (pH 5.5–6.5).
Fertilizer: Mix in a balanced, slow-release organic fertilizer or well-rotted compost to provide nutrients.
Tip: Ensure the soil is loose and fluffy to allow tubers to form easily.
5. Plant the Potatoes
Place 3–5 seed potato chunks on the soil, eyes facing up, spaced evenly.
Cover with 3–4 inches of soil mix.
Water gently until the soil is moist but not soggy.
As the plants grow, they’ll produce tubers above the seed potatoes. You’ll need to “hill” them by adding more soil to cover the stems, encouraging more tuber growth.
6. Care and Maintenance
Watering: Keep the soil consistently moist, checking daily as grow bags dry out faster than ground soil. Avoid overwatering to prevent rot.
Hilling: When the plants reach 6–8 inches tall, add 3–4 inches of soil mix to cover all but the top leaves. Repeat every 2–3 weeks until the bag is nearly full.
Pests and Diseases: Watch for pests like potato beetles or signs of blight (yellowing leaves with brown spots). Use organic solutions like neem oil or hand-pick beetles if you spot them.
Tip: If you notice issues, take a photo and research solutions online or consult a local gardening group for advice.
7. Harvest Your Potatoes
Growing Potatoes in Grow Bags are ready to harvest when the foliage turns yellow and dies back, usually 10–20 weeks after planting, depending on the variety.
New Potatoes: For small, tender potatoes, harvest 2–3 weeks after the plants flower by gently reaching into the bag.
Mature Potatoes: Wait until the foliage dies back completely, then tip the bag onto a tarp or dig through the soil to collect your crop.
Cure mature potatoes in a cool, dark, well-ventilated place for 1–2 weeks to toughen the skin for longer storage.
Tip: Store potatoes in a breathable sack in a cool, dark place to prevent sprouting or greening.
Bonus Tips for Success
Timing: Plant potatoes in early spring (or late winter in mild climates) when soil temperatures are above 45°F (7°C). In warmer regions, you can plant a second crop in late summer for a fall harvest.
Rotate Crops: If reusing grow bags, avoid planting potatoes in the same soil two years in a row to prevent disease buildup.
Companion Planting: Grow potatoes alongside beans or marigolds to deter pests naturally.
