Planting and Growing Purple Potatoes: Essential Care Guide

Now that you’ve chosen your favorite types of purple potatoes, let’s talk about getting them into the ground. Growing potatoes is incredibly satisfying, and with a few types of purple potatoes best practices, you’ll be well on your way to a colorful harvest.

This types of purple potatoes care guide covers everything from soil prep to ongoing maintenance.

Choosing Your Spot and Preparing the Soil

Potatoes love sunshine! Pick a spot in your garden that receives at least 6-8 hours of direct sunlight daily. Good drainage is also crucial to prevent rot.

Purple potatoes thrive in loose, fertile, slightly acidic soil (pH 5.0-6.0). Amend heavy clay soils with compost or well-rotted manure to improve drainage and fertility. A soil test can help you determine what amendments are needed.

Chitting Your Seed Potatoes

Before planting, “chit” your seed potatoes. This means allowing them to sprout indoors in a cool, bright spot for a few weeks before planting. This gives them a head start and can lead to earlier, larger yields.

Simply place your seed potatoes in a single layer in an egg carton or shallow tray. You’ll see short, stout green or purple sprouts emerge from the “eyes.”

The Planting Process

  1. Cut Seed Potatoes: If your seed potatoes are large, cut them into pieces, ensuring each piece has at least 1-2 “eyes” (sprouts). Let the cut pieces dry for a day or two to form a protective callous.
  2. Dig Trenches or Hills: Dig trenches about 6-8 inches deep and 3 feet apart. If you prefer hilling, you can plant them in individual holes.
  3. Planting Depth and Spacing: Plant your chitted or cut seed potato pieces 10-12 inches apart in the trench, with the eyes facing upwards.
  4. Cover: Cover them with about 4 inches of soil.
  5. Hilling: As the plants grow to about 6-8 inches tall, begin “hilling.” Gently mound soil around the stems, leaving only the top few inches of foliage exposed. Repeat this process every couple of weeks until the plants are about a foot high. Hilling protects the developing tubers from sunlight (which can turn them green and toxic) and encourages more potatoes to form.

Watering and Fertilizing

Consistent moisture is key for healthy potato development. Aim for about 1 inch of water per week, either from rain or irrigation, especially during flowering and tuber formation.

Avoid overhead watering late in the day, as this can encourage fungal diseases. Fertilize with a balanced organic fertilizer at planting time, and consider a boost of phosphorus and potassium when the plants start to flower to encourage tuber growth.

Pest and Disease Management

Even with the best care, potatoes can encounter pests and diseases. Regular monitoring is your best defense.

  • Colorado Potato Beetles: Hand-pick these striped beetles and their reddish-orange larvae.
  • Aphids: A strong spray of water or insecticidal soap can manage aphid populations.
  • Late Blight: This serious fungal disease can wipe out a crop. Choose resistant varieties if available and ensure good air circulation. Remove and destroy infected plants immediately.
  • Scab: Often caused by high soil pH. Ensure your soil is slightly acidic and avoid over-fertilizing with fresh manure.

Harvesting and Enjoying Your Purple Potato Bounty

The moment you’ve been waiting for! Knowing how to types of purple potatoes for harvest and storage will ensure you get the most out of your hard work.

Knowing When to Harvest

Purple potatoes are typically ready for harvest when the plant’s foliage begins to yellow and die back, usually 90-120 days after planting, depending on the variety.

For “new” potatoes (smaller, tender tubers), you can gently dig around the plant about 2-3 weeks after flowering begins, carefully removing a few without disturbing the main plant.

Curing and Storing Your Harvest

Once the foliage has completely died back, wait about two weeks before harvesting. This allows the potato skins to thicken, improving their storage life.

  1. Dig Carefully: Use a digging fork or spade, starting a foot or so away from the plant stem to avoid piercing the tubers. Loosen the soil and gently lift the entire plant, brushing off excess dirt.
  2. Cure: After harvest, “cure” your potatoes by spreading them in a single layer in a cool, dark, well-ventilated area (around 50-60°F / 10-15°C) for 1-2 weeks. This helps heal any minor wounds and further toughen the skins.
  3. Store: Store cured purple potatoes in a cool (40-50°F / 4-10°C), dark, humid place with good air circulation. Burlap sacks, wooden crates, or perforated plastic bins work well. Avoid storing them in the refrigerator, as this can convert starches to sugars and affect texture.

Culinary Delights with Purple Potatoes

Purple potatoes are incredibly versatile in the kitchen. Their striking color makes them perfect for adding visual interest to any meal.

  • Roasting: Toss with olive oil, rosemary, salt, and pepper for a simple, vibrant side dish.
  • Mashing: Create a beautiful, colorful mash. Be mindful that some varieties might turn slightly blue when mashed with an acidic ingredient like lemon juice.
  • Salads: Their firm texture holds up well in potato salads.
  • Chips & Fries: Slice thinly for homemade purple potato chips or cut into wedges for baked fries.
  • Soups & Stews: Add chunks to hearty dishes for a nutritious boost.

To preserve their vibrant color, try steaming or microwaving them instead of boiling for long periods. A splash of vinegar or lemon juice during cooking can also help stabilize the anthocyanins, though this can sometimes affect the color, turning it slightly bluer.

Troubleshooting Common Problems with Purple Potato Growing

Even seasoned gardeners face challenges. Knowing how to address common problems with types of purple potatoes will help you keep your plants healthy and productive.

Scab and Other Fungal Issues

Potato scab (common scab) causes rough, corky spots on the potato skin. It’s often worse in alkaline soils. To prevent it, maintain a slightly acidic soil pH (5.0-6.0) and avoid fresh manure, which can raise pH.

Late blight is a more serious fungal issue. Look for water-soaked lesions on leaves and stems. Remove and destroy infected plants immediately and consider preventative organic fungicides if blight is common in your area.

Pest Attacks: Colorado Potato Beetles and Aphids

These are the most common potato pests. For Colorado Potato Beetles, consistent hand-picking (and crushing) of adults, larvae, and egg masses is effective in smaller gardens. For aphids, a strong spray of water can dislodge them, or you can use insecticidal soap.

Poor Yields or Small Tubers

If your purple potatoes aren’t as abundant or large as you’d hoped, several factors could be at play:

  • Insufficient Sun: Ensure your plants get at least 6-8 hours of direct sun.
  • Inconsistent Watering: Dry spells, especially during tuber formation, can lead to small potatoes.
  • Lack of Nutrients: Potatoes are heavy feeders. Ensure your soil is fertile and provide a balanced fertilizer.
  • Improper Hilling: Not hilling enough means fewer tubers develop or they get sun-scorched.
  • Too Much Nitrogen: While nitrogen promotes leafy growth, too much can inhibit tuber development. Use a balanced fertilizer.

Color Fading During Cooking

While purple potatoes generally hold their color well, some varieties or cooking methods can cause fading or a shift in hue. To maintain vibrancy:

  • Steam or Microwave: These methods expose the potatoes to less water and heat, preserving more pigment.
  • Cook Quickly: Don’t overcook them.
  • Acidic Environment: A tiny splash of vinegar or lemon juice in the cooking water can sometimes help stabilize the color, but experiment as it can also shift the color towards blue.

Sustainable and Eco-Friendly Practices for Purple Potato Growers

At Greeny Gardener, we believe in nurturing our gardens and the planet. Adopting sustainable types of purple potatoes growing methods isn’t just good for the environment; it often leads to healthier plants and better yields.

Embrace these eco-friendly types of purple potatoes practices for a thriving, responsible garden.

Crop Rotation

Potatoes belong to the nightshade family. To prevent disease buildup in the soil, avoid planting potatoes (or tomatoes, peppers, eggplants) in the same spot for at least 3-4 years. Rotate with other plant families like legumes or brassicas.

Companion Planting

Certain plants can help deter pests or improve potato growth. Plant marigolds to repel nematodes, or beans and peas to fix nitrogen in the soil (though plant them a little distance away as beans can stunt potato growth if too close).

Organic Pest Control

Instead of chemical pesticides, rely on organic solutions like hand-picking pests, using insecticidal soaps, or encouraging natural predators (e.g., ladybugs, lacewings) by providing habitat.

Water Conservation

Use mulch (straw, shredded leaves) around your potato plants. Mulch helps retain soil moisture, suppress weeds, and keep soil temperatures consistent, reducing the need for frequent watering.

Composting

Feed your soil with nutrient-rich compost. This improves soil structure, fertility, and microbial life, reducing the need for synthetic fertilizers. Your potato plants will thank you!
