Step-by-Step Guide: How to Grow Potatoes in Boxes

If you have limited space or poor soil quality, growing potatoes in boxes can be a great solution. This method allows you to grow your own potatoes even if you don’t have a large garden or a dedicated vegetable patch. Plus, it’s a fun and rewarding project that can be enjoyed by both experienced gardeners and beginners.

Growing potatoes in boxes offers several advantages. First, it allows you to control the soil quality, ensuring that your potatoes receive the nutrients they need to thrive. Second, it helps prevent the spread of diseases and pests, as the boxes create a barrier between your potatoes and the surrounding soil. Lastly, it makes harvesting easier, as you can simply lift the boxes to reveal your bountiful potato crop.

To get started, you’ll need some sturdy boxes or containers. Wooden boxes or plastic containers with drainage holes work well. Make sure they are deep enough to accommodate the growth of your potatoes. Next, fill the boxes with a nutrient-rich soil mix. A combination of compost, potting soil, and sand is ideal for potatoes.

Once your boxes are filled with soil, it’s time to plant your potatoes. Choose seed potatoes that are certified disease-free and have sprouts or “eyes” on them. Cut the seed potatoes into smaller pieces, making sure each piece has at least one sprout. Plant the seed potatoes about 4-6 inches deep in the soil, with the sprouts facing up. Space them about 12 inches apart to allow room for growth.

As your potatoes grow, make sure to water them regularly, keeping the soil moist but not waterlogged. You can also add a layer of straw or mulch on top of the soil to help retain moisture and suppress weeds. As the plants grow taller, you can add more soil or straw to the boxes to encourage the growth of more potatoes along the stem.

Harvesting your potatoes is the most exciting part of the process. Once the plants start to flower and the foliage begins to turn yellow and die back, it’s time to harvest. Carefully lift the boxes and sift through the soil to find your potatoes. Be gentle to avoid damaging the potatoes, and remove any that are damaged or diseased.

Now that you know how to grow potatoes in boxes, you can enjoy a bountiful harvest of your own homegrown potatoes. Whether you’re a seasoned gardener or a beginner, this method is a simple and effective way to grow potatoes in a small space. So grab some boxes, get your hands dirty, and start growing your own delicious potatoes!

Choosing the Right Boxes

When it comes to growing potatoes in boxes, choosing the right boxes is crucial for the success of your potato crop. Here are a few factors to consider when selecting the boxes:


The size of the boxes is an important consideration. Ideally, you should choose boxes that are at least 2 feet deep to allow for proper root development. The width and length of the boxes will depend on the available space you have for gardening.


The material of the boxes is another important factor to consider. You can use a variety of materials such as wood, plastic, or even metal. However, it’s important to choose a material that is sturdy and will not rot or degrade over time. Wood boxes are a popular choice as they are durable and provide good insulation for the potatoes.

Tip: Avoid using boxes made from treated wood, as the chemicals used in the treatment process can leach into the soil and affect the growth of your potatoes.


Proper drainage is essential for the health of your potato plants. Make sure the boxes you choose have drainage holes at the bottom to prevent waterlogging. Excess moisture can lead to root rot and other diseases, so it’s important to ensure good drainage.


Consider the accessibility of the boxes when choosing them for growing potatoes. You will need to regularly check on your plants, harvest the potatoes, and add more soil as the plants grow. Boxes that are too large or difficult to access may make these tasks challenging.

By considering these factors and choosing the right boxes, you can create an ideal growing environment for your potatoes and maximize your harvest.

Preparing the Boxes

Before you can start growing potatoes in boxes, you need to properly prepare the boxes. Here are the steps you should follow:

1. Choose the right boxes: Select boxes that are at least 2 feet deep and wide enough to accommodate the number of potato plants you plan to grow. Make sure the boxes have drainage holes at the bottom to prevent waterlogging.

2. Clean the boxes: Thoroughly clean the boxes to remove any dirt or debris. This will help prevent the spread of diseases and pests.

3. Line the boxes: Line the boxes with a layer of newspaper or cardboard. This will help retain moisture and prevent the soil from falling out of the drainage holes.

4. Fill the boxes: Fill the boxes with a well-draining potting mix or a mixture of compost, peat moss, and perlite. Leave about 4 inches of space at the top of the box to allow for watering.

5. Add fertilizer: Mix in a slow-release fertilizer or organic matter into the soil to provide nutrients for the potato plants.

6. Water the soil: Before planting the potatoes, water the soil in the boxes thoroughly. This will ensure that the soil is evenly moist and ready for planting.

7. Place the boxes: Choose a sunny location for the boxes, as potatoes require at least 6-8 hours of direct sunlight per day. Make sure the boxes are stable and level to prevent them from tipping over.

By following these steps to prepare the boxes, you will create an ideal environment for growing potatoes and increase your chances of a successful harvest.

Planting and Growing

Planting and growing potatoes in boxes is a great way to maximize your potato harvest, even if you have limited space. Here are the steps to successfully plant and grow potatoes in boxes:

1. Choose the Right Box

When selecting a box for growing potatoes, make sure it is at least 18 inches deep to allow for proper root development. The box should also have drainage holes to prevent waterlogging.

2. Prepare the Soil

Fill the box with a well-draining potting mix or a mixture of compost and soil. Potatoes prefer slightly acidic soil with a pH level of 5.0 to 6.0.

3. Chit the Potatoes

Chitting is the process of allowing the potatoes to sprout before planting. Place the seed potatoes in a cool, well-lit area for a few weeks until they develop small sprouts.

4. Plant the Potatoes

Place the chitted potatoes in the soil with the sprouts facing upwards. Space the potatoes about 6 inches apart to allow room for growth. Cover the potatoes with 3-4 inches of soil.

5. Water and Fertilize

Keep the soil consistently moist but not waterlogged. Water the potatoes regularly, especially during dry periods. Fertilize the plants every 2-3 weeks with a balanced fertilizer to promote healthy growth.

6. Hill the Potatoes

As the potato plants grow, mound additional soil around the stems to encourage tuber development. This process, known as hilling, helps prevent the potatoes from turning green and increases the yield.

7. Monitor for Pests and Diseases

Regularly inspect the potato plants for signs of pests or diseases, such as potato beetles or late blight. If any issues are detected, take appropriate measures to control and prevent further damage.

8. Harvest the Potatoes

Potatoes are ready to harvest when the foliage turns yellow and dies back. Carefully dig up the potatoes using a garden fork or shovel. Allow them to dry for a few hours before storing them in a cool, dark place.

3-4 inches 6 inches apart 5.0-6.0 Consistently moist Every 2-3 weeks


Harvesting potatoes from your box garden is an exciting and rewarding experience. Here are some steps to help you successfully harvest your potatoes:

1. Timing

It is important to know when to harvest your potatoes. Typically, potatoes are ready to be harvested when the plants have died back and the foliage has turned yellow or brown. This usually occurs about 2-3 weeks after the plants have finished flowering.

2. Preparation

Prior to harvesting, gently remove any remaining foliage from the plants. This will make it easier to access the potatoes in the boxes.

3. Emptying the Boxes

Step-by-Step Guide: How to Grow Potatoes in Boxes

Start by carefully emptying the contents of your boxes onto a clean tarp or sheet. Use a garden fork or your hands to gently sift through the soil and locate the potatoes.

4. Harvesting Potatoes

When you find a potato, gently lift it out of the soil. Be careful not to damage the potatoes or bruise them. If the potatoes are still attached to the plant, gently detach them.

5. Sorting and Storing

Once you have harvested all the potatoes, sort them by size and condition. Discard any damaged or diseased potatoes. Store the healthy potatoes in a cool, dark, and well-ventilated area to prevent them from sprouting.

By following these steps, you can enjoy a bountiful harvest of delicious homegrown potatoes from your box garden!
