How to grow potatoes

Growing potatoes is a rewarding and satisfying experience for gardeners of all levels. Whether you have a large backyard or a small patio, potatoes can be grown successfully in a variety of settings. This comprehensive guide will provide you with step-by-step instructions on how to grow potatoes, from selecting the right potato variety to harvesting and storing your crop. By following these guidelines, you’ll be well-equipped to cultivate delicious, homegrown potatoes that will delight your taste buds.

Choosing Potato Varieties:

Selecting the right potato variety is crucial for a successful potato harvest. There are countless potato varieties available, each with its own unique characteristics. Some popular potato types include russet potatoes, red potatoes, and Yukon Gold potatoes. Consider factors such as taste preference, cooking methods, and the specific growing conditions in your area when choosing your potato variety.

Preparing the Soil

Potatoes thrive in well-drained, loose soil that is rich in organic matter. Begin by clearing the planting area of any weeds or grass. Loosen the soil to a depth of at least 8 to 10 inches using a garden fork or tiller. Incorporate compost or well-rotted manure into the soil to improve its fertility and moisture-holding capacity. Aim for a slightly acidic soil pH level between 5.0 and 6.5.

Planting Potatoes

Potatoes are typically grown from seed potatoes, which are small tubers specifically grown for planting. To prepare your seed potatoes for planting, cut them into smaller pieces, ensuring that each piece contains at least one or two eyes (the small indentations from which sprouts emerge). Allow the cut pieces to dry for a day or two before planting to prevent rotting.

Plant your seed potatoes in trenches or holes, spaced about 12 to 15 inches apart, with the eyes facing upward. The depth of planting will depend on the potato variety and your climate. In general, plant them about 4 to 6 inches deep. Cover the seed potatoes with soil and water thoroughly.

Caring for Potato Plants

As your potato plants begin to grow, it’s essential to provide them with the care they need to thrive. Here are some important aspects to consider:


Potatoes require consistent moisture throughout the growing season. Ensure that the soil remains evenly moist but not waterlogged. Aim to provide about 1 to 2 inches of water per week, either through rainfall or irrigation.


Potatoes benefit from regular feeding. Apply a balanced fertilizer or compost during planting and side-dress with additional fertilizer once the plants have emerged. Follow the manufacturer’s instructions for application rates.


As the potato plants grow, they will develop stems and leaves above the ground. To encourage tuber development and protect the tubers from sunlight, hill up the soil around the base of the plants. This can be done by mounding soil or adding mulch around the stems, leaving only the top leaves exposed.

Weed Control:

Keep the potato bed free from weeds, as they can compete with the plants for nutrients and moisture. Regularly remove weeds by hand or use mulch to suppress weed growth.

Pest and Disease Management

Potatoes can be susceptible to various pests and diseases. Here are a few common issues and preventive measures:


These small, sap-sucking insects can damage potato plants. Use insecticidal soap or neem oil to control aphid populations. Introducing beneficial insects like ladybugs can also help in aphid control.

Potato Beetles:

These beetles can defoliate potato plants if left unchecked. Handpick and destroy adult beetles and their larvae. If the infestation is severe, consider using organic insecticides labeled for potato beetle control.

Late Blight:

Late blight is a fungal disease that can cause significant damage to potato plants. To prevent late blight, choose disease-resistant potato varieties and practice proper spacing and ventilation to promote airflow. Remove and destroy any infected plants to prevent the spread of the disease.


Scab is a bacterial disease that causes rough, scaly patches on potato tubers. Plant scab-resistant varieties and maintain consistent soil moisture levels to reduce the risk of scab. Crop rotation and avoiding acidic soil can also help prevent scabs.

Harvesting Potatoes

Potatoes can be harvested when the foliage turns yellow and begins to die back. Carefully dig up the plants using a fork or shovel, being cautious not to damage the tubers. Brush off any excess soil and allow the potatoes to cure for a few hours in a cool, dry place. This will toughen the skin and improve their storage potential.

Storing Potatoes

To store potatoes successfully, follow these guidelines:


After harvesting, cure the potatoes for about two weeks at a temperature of around 45 to 60°F (7 to 15°C) and high humidity. This process allows the skins to further harden, extending their storage life.

Storage Conditions:

Store cured potatoes in a cool, dark, and well-ventilated area. The ideal storage temperature is between 35 and 40°F (2 to 4°C) with a relative humidity of around 90 percent. Avoid storing potatoes near fruits, as they release ethylene gas, which can cause potatoes to sprout.

Storage Containers:

Use breathable containers such as burlap or paper bags, wooden crates, or mesh bags for potato storage. Avoid plastic bags or airtight containers, as they can trap moisture and promote rot.

Regular Inspection:

Periodically check stored potatoes for any signs of spoilage or sprouting. Remove any damaged or rotten potatoes to prevent the spread of decay.

Troubleshooting Common Issues

Here are solutions to some common potato-growing problems:


Potatoes exposed to light turn green and develop a bitter taste. Store harvested potatoes in a dark environment to prevent greening.


Soft rot or black rot can affect potatoes during storage. Proper curing, ventilation and regular inspection help prevent rot. Remove any affected potatoes promptly.

Hollow Heart:

A hollow heart is a physiological disorder that causes a hollow cavity in the center of the potato. It is often the result of rapid growth due to fluctuating moisture levels or excessive nitrogen fertilization. Maintain consistent moisture levels and avoid excessive nitrogen application.

Fun Potato Facts:

Potatoes are the fourth most consumed food crop in the world, after rice, wheat, and corn.

The Incas were the first to cultivate potatoes over 7,000 years ago in the Andes Mountains.

The world’s largest potato weighed in at 18 pounds and 4 ounces (8.28 kilograms).

Potatoes are a rich source of vitamin C, potassium, and dietary fiber.

The potato is the leading vegetable crop in the United States.
