Identifying Sprouted Potatoes

When planting sprouted potatoes, it’s essential to select the right ones for the best chance of successful growth. Look for potatoes with firm, healthy sprouts that are around 1-2 inches long. Avoid potatoes with shriveled or mushy sprouts, as they may not grow well. If you’re unsure about the sprouts, you can also perform a simple test to check the viability of the sprouted potatoes.

To test a sprouted potato’s viability, fill a glass or jar with water and suspend the potato in the water using toothpicks. The sprouts should be above the water while the rest of the potato is submerged. Place the glass in a warm, sunny spot and observe the sprouts for a few days. If the sprouts continue to grow and develop, the potato is likely viable for planting. If there is no growth or the sprouts deteriorate, it’s best to discard the potato and choose another one.

Preparing The Planting Area

Before planting your sprouted potatoes, it’s important to prepare the planting area to provide the best conditions for their growth. Choose a location that receives full sunlight for at least six to eight hours a day. Additionally, ensure that the soil in the chosen area is well-draining to prevent waterlogging, which can lead to rotting of the potatoes. Avoid compacted or clayey soils, as they can hinder proper root development and tuber formation.

If you’re planting potatoes in the ground, prepare the soil by loosening it to a depth of at least 8-10 inches. Remove any debris, such as rocks or roots, and incorporate organic matter, such as compost or well-rotted manure, to improve soil structure and fertility. For container planting, choose a large container with drainage holes at the bottom to allow excess water to escape.

Selecting A Suitable Time For Planting

Potatoes are sensitive to frost, so it’s crucial to plant them after the last frost date in your region. For many areas, this means planting in the early spring, once the soil has started to warm up. To determine the average last frost date in your area, consult a local gardening guide or a reliable online source. Planting too early can expose the young plants to potential frost damage, while planting too late may result in a shortened growing season and reduced yields.

Choosing The Right Type Of Soil

The type of soil you plant your sprouted potatoes in can significantly impact their growth and productivity. Potatoes thrive in loose, well-draining soil with a slightly acidic pH ranging from 5.8 to 6.5. Sandy loam and loamy soils are generally well-suited for potato cultivation, as they provide good aeration and drainage while retaining adequate moisture for the plants.

Before planting, you can conduct a soil test to assess the pH and nutrient levels of the soil. Soil testing kits are readily available at garden centers, or you can send a soil sample to a professional testing facility for more detailed analysis. Based on the test results, you can amend the soil with organic matter, lime to raise pH if necessary, or elemental sulfur to lower pH, ensuring that the planting site provides an optimal growing environment for your potatoes.

Planting The Sprouted Potatoes

Now that you have identified suitable sprouted potatoes and prepared the planting area and soil, it’s time to plant the sprouted potatoes.

  1. Cutting the Potatoes: If the sprouted potatoes are large, you can cut them into smaller pieces to plant. Each piece should contain at least one healthy sprout, also known as an "eye." The ideal size for planting chunks is around 1.5 to 2 inches in diameter, and each piece should have 1–2 sprouts for best results.

  2. Drying the Cut Potatoes: After cutting, allow the potato chunks to dry and form a protective layer over the cut surfaces. This process, known as "suberization," helps prevent rotting and disease by sealing the wounds and reducing the risk of infection.

  3. Planting the Potatoes: Once the cut potatoes have dried, it’s time to plant them. Dig furrows or individual planting holes around 3–4 inches deep and spaced 12–15 inches apart in rows, for ground planting. For container planting, fill the container with 6–8 inches of soil and place the potato pieces on top, then cover with an additional 3–4 inches of soil.

  4. Covering with Soil: Gently cover the planted potato pieces with soil, ensuring that the sprouts are facing upward. Firm the soil lightly to secure the potatoes in place.

  5. Watering: After planting, water the soil thoroughly to encourage the initial growth of the potato plants. Keep the soil consistently moist but not waterlogged to support healthy sprout development and root establishment.

Caring For The Plants

Once your sprouted potatoes are planted, it’s essential to provide appropriate care to ensure their optimal growth and development.

  1. Hilling: As the potato plants grow, they will produce stems with foliage above the soil surface. To protect the developing tubers from being exposed to sunlight and turning green, it’s important to hill the plants by mounding soil around the stems. Begin hilling when the plants are around 6–8 inches tall, and continue to mound soil gradually around the stems throughout the growing season.

  2. Watering: Potatoes require consistent moisture for healthy growth, especially during the tuber formation stage. While it’s important to avoid waterlogging, ensure that the soil remains evenly moist by providing regular, deep watering, particularly during dry periods.

  3. Fertilizing: Depending on the initial soil fertility and the growth stage of the plants, you may need to provide supplemental fertilization. A balanced fertilizer with a higher potassium content, such as a 5-10-10 formulation, can support tuber development. Apply the fertilizer according to the manufacturer’s instructions, typically as a side-dressing around the plants when they are actively growing.

  4. Pest and Disease Management: Monitor the potato plants for signs of pest infestations or disease, such as potato beetles, aphids, or fungal infections. Consider using organic or targeted interventions to manage any issues that arise, such as handpicking pests, applying beneficial insect releases, or using natural fungicides.

  5. Harvesting: The time to harvest your potatoes will depend on the variety you planted and your growing conditions. You can start harvesting new potatoes when the plants begin to flower, typically 7–8 weeks after planting. For mature potatoes, wait until the tops of the plants have died back, then carefully dig up the tubers, taking care not to damage them.

Planting sprouted potatoes can be an exciting and rewarding experience, resulting in a bountiful harvest of fresh, homegrown tubers. By selecting healthy sprouted potatoes, preparing the planting area and soil, and providing proper care throughout the growing season, you can enjoy a successful potato crop in your own garden. Whether you choose to plant them in the ground or in containers, the process of growing potatoes from sprouted spuds offers a hands-on opportunity to connect with the natural cycle of plant growth and cultivation.

Caring For The Planted Potatoes

Planting potatoes that have sprouted is a great way to utilize those potatoes that have been sitting in your pantry for too long. When a potato sprouts, it means it is ready to grow and planting it can lead to a bountiful harvest.

To begin with, it is important to prepare the soil prior to planting the sprouted potatoes. Potatoes thrive in loose, well-drained soil that is rich in organic matter. You can start by adding compost or well-rotted manure to the soil to improve its fertility and structure.

Once the soil is prepared, dig a trench or create raised beds where you will plant the sprouted potatoes. Ensure that the trench or bed is wide and deep enough to accommodate the tubers comfortably. Ideally, the depth should be around 4-6 inches (10-15 cm).

Now it’s time to place the sprouted potatoes in the prepared trench or bed. Make sure to plant them with the sprouts facing upwards and space them approximately 12-15 inches (30-38 cm) apart. This spacing will allow the growing plants to receive sufficient sunlight and have enough room for the tubers to develop underground.

Cover the sprouted potatoes with a layer of soil, leaving a small mound or ridge on top. As the plants grow, you can continue to add soil around the stems to encourage more tuber formation and protect them from direct sunlight, which can cause them to turn green.

Watering Requirements For Growing Potatoes

Watering is crucial for the healthy growth of potatoes. After planting, it is essential to keep the soil consistently moist but not soggy. Water the plants thoroughly immediately after planting and then regularly throughout the growing season.

A good rule of thumb is to provide about 1-2 inches (2.5-5 cm) of water per week, either through rainfall or irrigation. However, it is important to monitor the soil moisture level and adjust the watering accordingly. Overwatering can lead to root rot, while underwatering can result in stunted growth and reduced yields.

Mulching can be beneficial in potato cultivation, as it helps to conserve moisture, suppress weeds, and maintain an even soil temperature. Apply a layer of organic mulch, such as straw or wood chips, around the plants, ensuring that the sprouts are still exposed.

Protecting The Sprouted Potatoes From Pests And Diseases

Potatoes can be vulnerable to several pests and diseases, but with proper care, you can minimize the risk and protect your crop. Here are some common pests and diseases to be aware of and preventive measures you can take:

  1. Potato beetles: Colorado potato beetles can be a common pest in potato cultivation. Monitor your plants regularly and remove any visible beetles or larvae by hand. If the infestation is severe, you can consider using insecticidal soap or organic insecticides labeled for potato beetles.

  2. Aphids: Aphids are small, sap-sucking insects that can cause damage to potato plants. Regularly inspect your plants for aphids and control them by spraying a strong stream of water or using insecticidal soap.

  3. Late blight: Late blight is a fungal disease that can devastate potato crops. To prevent late blight, choose disease-resistant potato varieties and ensure proper spacing between plants for good air circulation. If late blight is present in your area, consider applying fungicides labeled for late blight prevention.

  4. Early blight: Early blight is another fungal disease that affects potatoes. It manifests as dark spots on the leaves and can lead to defoliation. To prevent early blight, avoid overhead watering, as moisture on the leaves creates favorable conditions for the disease. Apply fungicides labeled for early blight prevention if necessary.

Regularly inspecting your plants and taking immediate action at the first sign of pests or diseases is crucial to prevent further damage and ensure a healthy crop.

Harvesting And Storing The Potatoes

The time to harvest your potatoes will vary depending on the variety you planted. Early or new potatoes can be harvested as soon as the plants start to flower, usually around 2-3 months after planting. These potatoes are small and tender with thin skins. Mature potatoes, on the other hand, can be harvested when the plants have died back and the skins have set, typically 3-4 months after planting.

To harvest your potatoes, gently loosen the soil around the plants with a garden fork or your hands. Be careful not to damage the tubers as you dig them up. Start harvesting from the outer edges of the bed and work your way towards the center.

Once harvested, brush off any excess soil and allow the potatoes to cure in a cool, dark, and well-ventilated area for 1-2 weeks. During this curing period, the skins will thicken, and the potatoes will become less prone to bruising and rotting.

After curing, sort the potatoes and remove any damaged or diseased ones. Store the good-quality potatoes in a cool, dry, and dark place, such as a cellar or basement. Avoid storing them near onions or apples, as these can hasten sprouting.


Planting potatoes that have sprouted is a great way to make use of those potatoes that may otherwise go to waste. By following the steps outlined in this article, you can successfully plant and care for sprouted potatoes to enjoy a bountiful harvest. Remember to prepare the soil, provide adequate water, protect against pests and diseases, and properly harvest and store the potatoes. With proper care and attention, you can reap the rewards of your efforts with a delicious and homegrown potato crop.
