There are few gardening moments as magical as the potato harvest. It’s a true treasure hunt, digging through the earth to unearth a bounty of fresh, firm, homegrown tubers. The idea of it is fantastic. The reality of it, however, is what stops many gardeners in their tracks. It traditionally requires digging trenches, “hilling” with piles of dirt, and, worst of all, the back-breaking work of digging up the harvest with a fork, inevitably spearing half your crop. This, combined with the need for a large garden plot, makes potatoes a “no-go” for many.
But what if you could have that magical harvest without a single shovel? What if you could grow a 10-pound bounty on your sunny patio or apartment balcony? Welcome to the wonderful, revolutionary world of a “no-dig” garden. Learning how to grow potatoes in containers is a game-changer for the modern gardener, and it’s not just possible—it’s often better than growing them in the ground.
This guide will walk you through every simple step, from choosing your “seed” to the giddy satisfaction of dumping out your pot and revealing a cascade of perfect, homegrown potatoes.
Why Grow Potatoes in Containers? The No-Dig Advantage
This method isn’t just a novelty; it solves the biggest problems associated with growing potatoes. For a beginner, it’s the absolute best way to guarantee a successful, manageable crop.
- No Garden Plot Needed: This is the most obvious benefit. If you have a sunny spot on a deck, patio, or balcony, you can grow potatoes in containers. It opens up this staple crop to urban gardeners and small-space dwellers.
- The Easiest Harvest of Your Life: This is the real magic. Forget digging. Forget the pitchfork. The harvest consists of laying a tarp on the ground, turning the container over, and dumping it out. The potatoes tumble out, clean and undamaged.
- Perfect Soil Conditions: Potatoes need loose, well-drained, acidic soil to thrive. In-ground, you might be fighting heavy clay or rocky soil. In a container, you get to be the architect, creating the Best Soil for Container Vegetables: Crafting the Perfect Potting Mix for a Bountiful Harvest.
- No Digging or Tilling: This method requires zero tilling. It’s a perfect “no-dig” system that saves your back and protects the soil structure.
- Pest & Disease Control: It’s much easier to spot and manage pests like the Colorado potato beetle when they’re at eye level. Furthermore, growing in a container with fresh soil eliminates the risk of soil-borne diseases (like potato scab) that might be lurking in your garden beds.
Step 1: Get Your “Seed” Potatoes (And What Not to Plant)
Your first critical step is sourcing your “seeds.” This is a major beginner pitfall.
Do NOT Plant Potatoes from the Grocery Store
It seems logical: find a potato in your pantry that’s sprouting and plant it, right? This is a mistake. Potatoes from the grocery store are almost always treated with a chemical “sprout inhibitor” to keep them from growing in the aisles (and in your pantry). This means they will struggle to grow, if they grow at all. Furthermore, they are not “certified” and can introduce devastating diseases, like potato blight, to your soil.
What You Need: Certified Seed Potatoes
You must buy “certified seed potatoes” from a local garden center or an online nursery. These are potatoes that are grown specifically for planting.
- They are certified disease-free.
- They are not treated with sprout inhibitors.
- They are sold in dozens of varieties, allowing you to grow exciting types you’ll never see in a store (like ‘Purple Majesty’ or ‘French Fingerling’).
“Chitting” Your Potatoes (A Highly Recommended Step)
“Chitting” is simply the process of encouraging your seed potatoes to sprout before you plant them. It gives them a powerful head start.
- Start 2-4 weeks before you plan to plant.
- Place your seed potatoes in a bright, cool (but not freezing) location. A sunny windowsill or a spot in a 60°F (15°C) garage is perfect.
- Place them “eye” side up. An old egg carton is the perfect tool for this—place one potato in each cup.
- Be patient. In a week or two, you’ll see short, thick, purplish-green sprouts emerge from the “eyes.” This is what you want! You’re looking for 1/2-inch to 1-inch long, sturdy sprouts. (Long, pale, white sprouts mean it’s too dark).
How to Cut Your Seed Potatoes
You don’t need to plant the entire potato. You can, and should, cut your seed potatoes into smaller pieces, which drastically increases your yield per pound.
- The Rule: Make sure each piece you cut has at least two “eyes” (the little divots where sprouts form).
- Size: Cut the potato into pieces roughly the size of a golf ball or large ice cube.
- Cure: After cutting, let the pieces sit out at room temperature for 2-3 days. This allows the cut surfaces to “scab over” and dry, which prevents them from rotting in the soil.
Step 2: Choosing the Perfect Potato Container
When you grow potatoes in containers, the container itself is your most important tool.
Size Matters: Go Big and Deep
Potatoes are a “root” crop (technically a “tuber” crop), but the potatoes themselves actually grow off the buried stem, above the seed piece. This means you need a container that is deep to allow for “hilling” (more on that in a moment).
- The Minimum: A 5-gallon bucket is the absolute minimum for 1-2 potato plants.
- The Ideal: Bigger is always better. A 15-20 gallon container (like a large fabric pot or a storage tote) is fantastic. A half-whiskey-barrel is a beast.
- The Goal: You need at least 18-24 inches of depth to work with.
The Most Critical Feature: Drainage
This is non-negotiable. Potatoes will rot in soggy, waterlogged soil. Your container must have ample, large drainage holes.
- If you’re using a 5-gallon bucket, drill at least 5-6 half-inch holes in the bottom.
- If you’re using a large plastic storage tote, use a drill or a hot screwdriver to melt a dozen holes in the bottom.
- Fabric grow bags are ideal because they have “air-pruning” and perfect drainage built-in.
Popular Container Options
- Fabric Grow Bags: My personal favorite. They’re cheap, they store flat in winter, they’re lightweight, and they prevent overwatering.
- 5-Gallon Buckets: Often free from bakeries or delis. Make sure they are “food safe” (look for the #2, #4, or #5 recycling symbols).
- Large Plastic Totes: A 18-gallon tote is a perfect mini-potato-bed.
- “Potato Bags”: These are grow bags with a “Velcro window” at the bottom. This is a bit of a gimmick. It’s fun to “rob” a few new potatoes, but the real harvest happens at the end of the season by dumping the whole bag.
Step 3: The “Hilling” Method Explained
This is the most important concept in all of potato growing, and it’s the entire secret to why container growing works so well.
The Potato Fact: Potatoes (the tubers you eat) do not grow from the roots. They grow on special stems called “stolons” that emerge from the main stem, above the seed piece you planted.
This means you must continually bury the stem as the plant grows. This is called “hilling.” In a container, you’re just layering soil instead of piling it up.
Step 4: How to Plant and Layer Your Potatoes
Here is the simple, step-by-step planting process.
- Get Your Soil: Fill your container with 4-6 inches of your prepared soil mix (see below). Do not fill the container to the top.
- Plant Your Potatoes: Place your “chitted” and “cured” seed potato pieces on top of this soil layer. Space them out, “eye” side up.
- In a 5-gallon bucket: Plant 2-3 pieces.
- In a 15-gallon grow bag: Plant 4-5 pieces.
- Cover: Cover your seed potatoes with another 3-4 inches of soil.
- Water: Water them in well, so the soil is thoroughly moist but not soaking.
- Wait: In 1-2 weeks, you’ll see the first green leafy shoots emerge from the soil.
The “Hilling” Process in Action
This is what you’ll do for the next 6-8 weeks.
- Let it Grow: Let the green potato plant grow until it’s about 6-8 inches tall.
- Add More Soil: Now, add another 4-5 inches of your soil mix to the container. Gently pour it in around the plants, burying the stem until only the top 2-3 inches of leaves are showing.
- Repeat: Let the plant grow again. When it’s another 6-8 inches tall, repeat the process. Add more soil, burying the stem, leaving just the top leaves.
- Continue: Keep doing this “layering” process until you have filled your container to the top.
Every time you bury the stem, you are telling the plant, “This is underground now! Grow potatoes here!” You are creating a 12-18 inch-long “potato factory” on the stem.
How to Care for Your Potato Containers
Once your hilling is done, your job is just basic maintenance.
Sunlight: Full Sun is Best
Potatoes are a “full sun” crop. They need a minimum of 6-8 hours of direct, intense sunlight to power the photosynthesis that creates the tubers. Find the sunniest spot on your patio or in your yard. A Garden Sun Map: How to Maximize Sunlight for Your Vegetables can help you identify this.
Watering: The Container Gardener’s #1 Job
This is the most important part of container care.
- In-ground plants: can seek out water with deep roots.
- Container plants: are 100% reliant on you.
- The Rule: Potatoes need consistent moisture, especially when they are forming tubers. Do not let the container dry out completely. This can lead to a low yield or “potato scab.”
- The Test: Stick your finger 2 inches into the soil. If it’s dry, water deeply until water comes out of the drainage holes. If it’s moist, check again tomorrow. In the heat of summer, you will likely need to water every single day.
Fertilizing Your Hungry Potatoes
You are asking a 2’x2′ space to produce 10 pounds of food. It needs fuel.
- Good Soil: Start with a good potting mix that has compost in it.
- Feed Them: After the plants have flowered, they are actively forming tubers. This is when you should feed them. Use a balanced Organic Fertilizer for Vegetables or one that is high in potassium (the “K” in N-P-K), like a “tomato fertilizer.” Avoid high-nitrogen fertilizers, which will give you all leaves and no potatoes.
Troubleshooting: Pests and Problems
The main benefit of container growing is that pest pressure is low, but you should know what to look for.
- Colorado Potato Beetle: This is the #1 potato pest. It’s a yellow-and-black striped beetle. In a container, the solution is easy: hand-pick them and drop them in a jar of soapy water.
- Potato Blight: This is a serious fungal disease (the cause of the Irish Potato Famine). It’s less common in containers with fresh soil, but you should still practice Eco-Friendly Pest Control by watering only the soil, not the leaves, to keep them dry.
- Green Potatoes: If your potatoes are exposed to sunlight, they will turn green. This green skin contains “solanine,” which is toxic. This is another huge benefit of the “hilling” method—it keeps all your tubers in the dark, where they belong.
The Grand Finale: Harvesting Your Potato Treasure
This is the part you’ve been waiting for.
When to Know Your Potatoes Are Ready
Your potato plant will tell you exactly when it’s done.
- The Plant Dies: In late summer or early fall, the green, leafy plant will turn yellow, then brown, and it will fall over and die. This is normal. This is your signal.
- What it Means: The plant’s life cycle is over. It has finished sending all its energy down into the tubers.
- Wait (Optional): After the plant has died, you can leave the potatoes in the soil for another 1-2 weeks. This helps “cure” the skins and makes them last longer in storage. Do not water during this time.
The “Dump”: The Easiest Harvest You’ll Ever Have
- Get a Tarp: Lay down a large tarp, an old sheet, or just do it on your lawn.
- Turn it Over: Grab your potato container, haul it to the tarp, and dump it over.
- The Treasure Hunt: Sift through the loose, fluffy soil with your hands. It’s the most satisfying harvest in all of gardening. You will find dozens of potatoes, clean, undamaged, and ready to eat.
Storing Your Bounty
- “New” Potatoes: If you can’t wait, you can gently dig into the side of the bag mid-season to “rob” a few small, tender “new” potatoes.
- Curing: For your main harvest, gently brush the dirt off (do not wash them!). Let them sit in a cool, dark, dry place for 1-2 weeks. This is called “curing” and it toughens the skin for long-term storage. Our guide to Harvest Storage Tips has more detail.
- Storage: Keep them in a cool, dark, and well-ventilated place (like a pantry or basement). A cardboard box with holes works great. Never store potatoes in the refrigerator.
A New Way to Garden
Learning to grow potatoes in containers is more than just a space-saving hack; it’s a fundamental shift in how you can approach food production. It takes a crop that was once intimidating, back-breaking, and space-hungry and turns it into a simple, accessible, and incredibly rewarding project for any gardener. That moment when you tip over the bag and see your harvest pour out is pure, unadulterated joy—a joy that every gardener, regardless of their space, deserves to experience.
