Growing Blue Potato: Tips for Success

Choosing the Right Variety

Blue potatoes are a delightful twist on the traditional spud, both in color and flavor. Look for varieties like 'Adirondack Blue' or 'All Blue' for the best results.

Get certified seed potatoes. It reduces the risk of disease and ensures a healthier crop.

The 'Adirondack Blue' variety is known for its vibrant blue color that remains even after cooking.

Preparing the Soil

Blue potatoes thrive in well-draining, fertile soil with a pH of 5.5 to 6.5. Adding compost or aged manure will improve soil structure and nutrient content.

I've found that using raised beds or mounds works wonders to keep the tubers well-drained and healthy.

  • Till the soil to loosen it up to a depth of 10-12 inches.
  • Mix in organic matter like compost or well-rotted manure.


Plant your seed potatoes in the spring, once the soil temperature reaches at least 50°F. Cut the seed potatoes into pieces, ensuring each piece has at least one "eye" or sprout.

Plant them about 4 inches deep and 12 inches apart in rows. Cover them lightly with soil initially.

For optimal growth, ensure your potatoes receive at least 6 hours of direct sunlight daily.

Watering and Care

Blue potatoes need consistent moisture, but they hate soggy soil. I water mine deeply once a week, making sure the soil is moist but not waterlogged.

Mulching the soil with straw or grass clippings helps retain moisture and keeps weeds at bay.

  1. Water at the base of the plants to avoid wetting the foliage.
  2. Check soil moisture regularly and adjust watering as needed.


A balanced organic fertilizer works well for blue potatoes. I usually opt for a 5-10-10 formula, applied in small doses throughout the growing season.

Potatoes are heavy feeders. Regular, light applications of fertilizer promote robust growth and larger tubers.


Your blue potatoes will be ready to harvest about 90-110 days after planting. When the vines begin to die back, it's a good sign they're nearing maturity.

Gently dig around the plants to unearth the tubers. Let them cure in a cool, dark place for a couple of weeks before use.


Store harvested blue potatoes in a cool, dark, and humid environment. Ideal storage temperatures range from 40-45°F.

A burlap sack or perforated bin helps control humidity and prevents rot.

Properly stored, blue potatoes can last up to 6 months, providing you with a colorful staple through the winter.

Growing blue potatoes at home is not only easy but also deeply rewarding. Whether you're a seasoned gardener or new to the game, these tips will help you enjoy a bountiful and beautiful harvest. Happy gardening!
