* **Purple Potatoes:** These potatoes have a striking purple color and a slightly nutty flavor. They’re rich in antioxidants and can be used in a variety of dishes.

Consider the maturity date of the potato variety. Early-season potatoes mature in about 70-80 days, mid-season potatoes in 90-100 days, and late-season potatoes in 110-120 days. Choose varieties that are well-suited to your growing season.

Sourcing Seed Potatoes

“Seed potatoes” are not actually seeds, but rather small potatoes or pieces of potatoes that are used to grow new plants. It’s crucial to use certified seed potatoes, as they are disease-free and will produce a healthier and more productive crop.

* **Where to Buy:** Purchase seed potatoes from reputable garden centers, nurseries, or online seed suppliers. Avoid using potatoes from the grocery store, as they may be treated with sprout inhibitors and may carry diseases.
* **Choosing Seed Potatoes:** Select seed potatoes that are firm, healthy, and free from blemishes or signs of disease. Look for potatoes with several “eyes,” which are the small buds from which new shoots will emerge. Size matters too; medium sized potatoes (about the size of an egg) are typically ideal.

Preparing Seed Potatoes: Chitting

“Chitting” is the process of encouraging seed potatoes to sprout before planting. This gives them a head start and can lead to an earlier harvest. It’s an optional step, but highly recommended, especially in cooler climates.

* **How to Chit:**
1. Place the seed potatoes in a cool, bright, frost-free location for 4-6 weeks before planting.
2. Arrange the potatoes in a single layer in egg cartons or trays, with the eyes facing upwards.
3. The potatoes will begin to develop short, green sprouts. These sprouts are what will eventually become the stems of the potato plants.

Preparing the Soil

Potatoes require well-drained, fertile soil with a slightly acidic pH (around 6.0-6.5). Proper soil preparation is essential for a successful potato crop.

* **Soil Testing:** Conduct a soil test to determine the pH and nutrient levels of your soil. This will help you determine what amendments are needed.
* **Amending the Soil:**
* **Organic Matter:** Incorporate plenty of organic matter, such as compost, well-rotted manure, or leaf mold, into the soil. This will improve drainage, aeration, and fertility.
* **Fertilizer:** Potatoes are heavy feeders, so they benefit from a balanced fertilizer. A fertilizer with a ratio of 10-10-10 or 14-14-14 is a good choice. Apply the fertilizer according to the package directions.
* **Sulfur:** If your soil is alkaline, you can lower the pH by adding sulfur.
* **Tilling:** Till the soil to a depth of at least 12 inches to create a loose and well-drained planting bed. Remove any rocks, roots, or other debris that could impede root growth.

Planting Potatoes

The timing of planting depends on your climate and the variety of potato you’re growing. In general, potatoes should be planted in early spring, after the last frost. The soil temperature should be at least 45°F (7°C).

* **Cutting Seed Potatoes:** If you’re using large seed potatoes, you can cut them into smaller pieces, each containing at least one or two eyes. Allow the cut pieces to dry for a day or two before planting to prevent rotting. Dust the cut surfaces with garden sulfur to further prevent rot.
* **Planting Method:**
1. Dig trenches that are 6-8 inches deep and 2-3 feet apart.
2. Place the seed potatoes in the trenches, with the eyes facing upwards, spacing them 12-15 inches apart.
3. Cover the seed potatoes with soil.

Hilling Potatoes

“Hilling” is the process of mounding soil around the base of the potato plants as they grow. This encourages the formation of more potatoes along the stems.

* **How to Hill:**
1. When the potato plants are about 6-8 inches tall, use a hoe or shovel to draw soil up around the stems, creating a small mound.
2. Repeat this process every 2-3 weeks, as the plants continue to grow. The final hill should be about 12 inches high.
3. Alternatively, you can use straw, hay, or compost to hill the potatoes. This method is particularly useful in areas with heavy clay soil.

Watering and Fertilizing

Potatoes need consistent moisture, especially during tuber formation. Water deeply and regularly, especially during dry spells.

* **Watering:** Water the potato plants when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to rot.
* **Fertilizing:** Side-dress the potato plants with a nitrogen-rich fertilizer every 4-6 weeks. This will help promote healthy growth and tuber development. Options include fish emulsion or a balanced granular fertilizer.

Controlling Pests and Diseases

Potatoes are susceptible to a variety of pests and diseases. Monitor your plants regularly and take action promptly if you notice any problems.

* **Common Pests:**
* **Colorado Potato Beetle:** These beetles can defoliate potato plants. Handpick them off the plants or use an insecticide.
* **Potato Flea Beetle:** These small beetles can damage the leaves of potato plants. Use an insecticide or row covers to protect the plants.
* **Aphids:** These small insects can suck the sap from potato plants. Use insecticidal soap or neem oil to control them.
* **Potato Leafhopper:** These insects can cause the leaves of potato plants to curl and turn yellow. Use an insecticide or row covers to protect the plants.
* **Wireworms:** These soil-dwelling larvae can damage potato tubers. Use beneficial nematodes or till the soil to expose them to predators.
* **Common Diseases:**
* **Early Blight:** This fungal disease causes dark spots on the leaves of potato plants. Use a fungicide or remove infected leaves.
* **Late Blight:** This fungal disease can quickly destroy potato plants. Use a fungicide or plant resistant varieties.
* **Scab:** This bacterial disease causes rough, corky lesions on potato tubers. Plant resistant varieties and avoid overwatering.
* **Fusarium Wilt:** This fungal disease causes potato plants to wilt and die. Plant resistant varieties and practice crop rotation.

Consider using organic pest control methods whenever possible. These methods are less harmful to the environment and to beneficial insects.

Harvesting Potatoes

The timing of harvest depends on the variety of potato and your personal preferences. Early-season potatoes can be harvested as soon as they reach a usable size. Late-season potatoes should be harvested after the foliage has died back.

* **Determining Maturity:** To check for maturity, dig up a test potato. If the skin is thick and doesn’t rub off easily, the potatoes are ready to harvest.
* **Harvesting Technique:**
1. Use a garden fork or shovel to carefully dig up the potatoes.
2. Be careful not to damage the tubers.
3. Gently brush off the excess soil.
4. Allow the potatoes to dry in a cool, dark, well-ventilated place for a few days. This will help to cure the skins and prevent rotting.

Storing Potatoes

Proper storage is essential for extending the shelf life of your potatoes.

* **Storage Conditions:** Store potatoes in a cool, dark, dry, and well-ventilated place. The ideal temperature is between 40°F (4°C) and 50°F (10°C).
* **Storage Containers:** Store potatoes in burlap sacks, paper bags, or ventilated plastic bins. Avoid storing them in airtight containers.
* **Storage Tips:**
* Remove any damaged or diseased potatoes before storing.
* Do not wash the potatoes before storing.
* Store potatoes away from apples and onions, as these fruits and vegetables release ethylene gas, which can cause potatoes to sprout.
* Check the potatoes regularly for signs of rot or sprouting.

Troubleshooting Common Problems

Even with the best planning, problems can sometimes arise when growing potatoes. Here are some common issues and how to address them:

* **Small Potatoes:** This can be caused by overcrowding, poor soil fertility, or insufficient watering. Space the plants further apart, amend the soil with compost and fertilizer, and water regularly.
* **Green Potatoes:** Potatoes that are exposed to sunlight will turn green and produce a toxic compound called solanine. Hill the potatoes properly to keep them covered with soil.
* **Rotting Potatoes:** This can be caused by overwatering, poor drainage, or disease. Improve drainage by amending the soil with organic matter and avoid overwatering. Use disease-resistant varieties.
* **Potato Scab:** This is a common disease that causes rough, corky lesions on the potato tubers. Plant resistant varieties, avoid overwatering, and maintain a slightly acidic soil pH.
* **Pest Infestations:** Monitor your plants regularly for pests and take action promptly. Use organic pest control methods whenever possible.
