How To Easily Grow Potatoes in Containers Following These 8 Steps

Growing potatoes in containers is a smart and rewarding way to produce your own fresh, organic spuds—especially if you have limited garden space.

Whether you’re working with a small patio, balcony, rooftop, or even a sunny doorstep, container-grown potatoes offer an efficient and manageable alternative to traditional in-ground planting.

Potatoes are a hardy, easy-to-grow vegetable that don’t require much attention beyond the basics.

By using the right container, soil, and planting technique, you can enjoy a healthy crop of delicious potatoes with minimal effort.

Best of all, container gardening helps you avoid soil-borne diseases, control pests more easily, and harvest without digging through heavy soil.

In this detailed guide, you’ll learn exactly how to grow potatoes in containers by following 8 easy, step-by-step instructions—perfect for beginners and seasoned gardeners alike.

Why Grow Potatoes in Containers?

Before diving into the steps, it’s worth highlighting the benefits of growing potatoes in containers:

• Ideal for small spaces like balconies, patios, or urban settings

• Better pest control, especially from underground invaders like wireworms and nematodes

• Fewer weeds and reduced competition for nutrients

• Easy harvesting—just tip the container and collect your potatoes

• Cleaner, more uniform tubers that develop in a controlled environment

• Extended growing season by moving containers to warm or sunny spots as needed

Step 1: Choose the Right Container

When growing potatoes, the container you use matters. Potatoes need room for their roots and tubers to expand downward, so depth and drainage are key.

Ideal container types:

• Large buckets (5-10 gallons or more)

• Grow bags (specially made for potatoes or vegetables)

• Plastic storage tubs

• Wooden crates or barrels

• Fabric pots

Minimum container size:

• At least 16 inches deep

• At least 12 inches wide

Make sure the container has adequate drainage holes. If you’re repurposing a bucket or bin, drill several holes at the bottom to avoid waterlogging, which can rot your crop.

Step 2: Select the Right Potato Variety

You can grow just about any potato in a container, but early and mid-season varieties tend to perform best. These types mature faster and are less susceptible to diseases.

Best potato varieties for containers:

• Yukon Gold

• Red Pontiac

• Fingerling

• Charlotte

• Norland

• Annabelle

• Kennebec

Avoid planting store-bought potatoes unless labeled as seed potatoes—they’re often treated with sprout inhibitors. Instead, buy certified disease-free seed potatoes from garden centers or trusted online nurseries.

Step 3: Prepare the Seed Potatoes

Once you have your seed potatoes, prepare them for planting by chitting—a process that encourages strong sprout development.

How to chit seed potatoes:

1. Place the seed potatoes in a cool, bright space (not direct sun).

2. Allow them to sit for 1–2 weeks until small green or purple sprouts emerge.

3. If potatoes are large (more than a chicken egg), cut them into chunks with at least one “eye” per piece. Let the cut sides dry for a day to prevent rot.

This step promotes healthier, faster-growing plants with a higher yield.

Step 4: Prepare the Soil Mix

Potatoes grow best in light, loose, and nutrient-rich soil. For containers, using a well-draining soil mix is essential to prevent water buildup and root rot.

Ideal soil mix:

• 2 parts high-quality potting mix

• 1 part compost or well-rotted manure

• 1 part perlite or sand (for improved drainage)

Avoid using heavy garden soil. You can also add a slow-release organic fertilizer high in phosphorus and potassium to encourage root and tuber development.

Step 5: Plant the Seed Potatoes

Now it’s time to plant. But unlike many vegetables, potatoes are planted in layers as they grow. You start with a small amount of soil and gradually add more as the plant matures—a process known as “hilling.”

Planting steps:

1. Fill your container with 4–6 inches of soil.

2. Place the seed potatoes sprout-side up, spacing them about 8 inches apart. For smaller containers, 2–3 seed potatoes is plenty.

3. Cover with another 3–4 inches of soil.

4. Water gently but thoroughly.

Avoid overwatering at this stage—keep the soil just moist, not soggy.

Step 6: Hill the Soil as the Plants Grow

As the potato plants grow, you’ll need to add more soil to keep the tubers covered and encourage more to develop along the buried stems.

Hilling process:

• When the green shoots are 6–8 inches tall, add 3–4 inches of soil or straw, covering the bottom leaves.

• Repeat the process every time the plants grow another 6 inches.

• Continue hilling until the container is nearly full.

This step is crucial. If tubers are exposed to sunlight, they turn green and develop solanine, which is toxic.

Step 7: Water and Feed Consistently

Potatoes in containers need regular watering since the soil dries out faster than in-ground beds. Consistent moisture is key to healthy growth.

Watering tips:

• Water deeply and allow excess to drain.

• Check soil daily in hot weather.

• Keep soil evenly moist, but avoid overwatering.

Fertilizer tips:

• Add an organic liquid fertilizer every 2–3 weeks.

• Choose a low-nitrogen, high-potassium mix to boost tuber production.

• Stop fertilizing once the plants start flowering.

Step 8: Harvest Your Potatoes

After flowering, your potatoes will be ready for harvest in 10 to 12 weeks (for early varieties). Once the foliage turns yellow and dies back, it’s time to collect your crop.

Harvesting steps:

• Stop watering 1–2 weeks before harvest to help the skins toughen.

• Gently tip over the container and sift through the soil.

• Collect all tubers, from baby potatoes to full-sized ones.

• Let the potatoes air dry in a shady, well-ventilated space.

Avoid washing the potatoes until you’re ready to eat them. For storage, keep them in a cool, dark, and dry place.

Bonus: Tips for Success

• Rotate potato varieties each season to avoid soil-borne diseases.

• Use straw or shredded leaves for hilling if you want a lighter medium.

• Avoid growing potatoes in the same container two seasons in a row without replacing the soil.

• Protect young shoots from frost by covering the container with cloth or fleece during cold snaps.

Growing potatoes in containers is one of the easiest and most satisfying ways to produce your own fresh food—especially in small spaces.

With just a few seed potatoes, a large pot, and regular care, you can harvest a bountiful supply of nutritious, homegrown potatoes in just a few months.
