Introduction to the Purple Majesty potatoes

Purple Majesty is one of the most popular purple potato varieties. These specialty potatoes are known as one of the best-tasting purple types and are known for keeping their rich hue when cooked. The pigment in these potatoes is due to antioxidants in the flesh, including anthocyanin and carotenoids.

Purple Majesty potatoes are high in Vitamin C, rich in antioxidants, and low in fat. They can be baked, boiled, or fried to give them a wonderful taste and texture for the table.

When to plant your seed potatoes?

Plant your seed potatoes outdoors a few weeks before the local last frost date. Here are some rule-of-thumb guidelines in terms of planting month by USDA plant hardiness zone:

  • Zone 10+: January
  • Zone 9: early February
  • Zone 8: late February
  • Zone 7: early March
  • Zone 6: late March
  • Zone 5: early April
  • Zone 4: late April
  • Zone 3: early May
  • Zone 2-: late May

If you’d like to be extra safe (and avoid having to cover baby plants if there is a late frost), wait until after the last frost before planting.

Preparing seed potatoes for planting

Seed potatoes are usually cut up into several pieces prior to planting (unless they are “mini tubers” and are only about 1-2 ounces each). Cut up your seed potatoes into a few pieces each so that each piece has 2-3 “eyes” (sprout holes). Set the cut potatoes out to dry.

You can also “chit” your seed potato pieces before planting. This entails keeping them indoors in a cool dry location for about 3-4 weeks and letting them sprout before planting. Keep them out of direct sunlight and plant the seed potatoes when the sprouts are a couple of inches long.

How to plant Purple Majesty potatoes?

Purple Majesty Potatoes can be planted in both gardens and containers. Choose an area that gets full sun. These potatoes need well-drained soil that is high in organic matter. Purple Majesty Potatoes are usually planted 2-4 weeks before the average last spring frost date in the local area.

When planting purple majesty potatoes, space the seed potatoes about 12 inches apart. Place the pieces in the ground so that the top of the tuber is about 3-6 inches below the soil surface. The sprouts should be pointed upwards. Replace about 3″ of soil after planting. Be sure to water well after planting.

Once the stems reach about 6″ above the ground, it’s time to start hilling your potatoes. This means using soil to keep the tubers from being exposed to light. Pile dirt up against the stems, leaving only a few inches of stem and foliage above the soil.

Watering requirements for Purple Majesty potatoes

Purple Majesty Potatoes need to be watered regularly, especially during the hot summer months. The soil should be kept moist, but not soggy. A good rule of thumb is to water once a week, or when the top 2-3 inches of soil are dry. They will likely require more water in overly hot temperatures and when grown in smaller containers. Drip irrigation or soaker hose watering is preferable to overhead watering with a sprinkler.

Fertilizing Purple Majesty potatoes

When it comes to fertilizing purple majesty potatoes, it’s best to use a balanced fertilizer that’s not too high in nitrogen. You can apply the fertilizer when you first plant the potatoes, and then again about 2-3 weeks later. Be sure to follow the instructions on the label, and avoid over-fertilizing purple majesty potatoes, as this can cause the tubers to become too large and misshapen. Some good options for purple majesty potato fertilizer include organic compost or manure, fish emulsion, or a balanced granular fertilizer.

Harvesting Purple Majesty potatoes

purple majesty potatoes are typically ready to harvest about 2-3 months after planting when the leaves of the plant begin to turn yellow and die back. To harvest the potatoes, carefully dig around the plant with a shovel or spade, being careful not to damage the tubers. Once you’ve dug up the potatoes, you can either leave them out in the sun to dry for a few hours before storing them or place them directly into shorter term storage.

Diseases affecting Purple Majesty potatoes

While purple majesty potatoes are generally somewhat resistant to disease, there are a few common diseases that can affect plants. These include early blight, late blight, and verticillium wilt. Early blight is characterized by brown or black spots on the leaves of the plant, while late blight causes the leaves to turn yellow and die. Verticillium wilt is a fungal disease that can cause the purple majesty potato plants to wilt and die.

To prevent these diseases from affecting your purple majesty potatoes, it’s important to practice good crop rotation and avoid planting the tubers in areas where other diseased plants have been growing. You should also water the plants regularly, use only high-quality seeds and plant material, and take care to remove any infected leaves or tubers as soon as possible.

Additionally, applying a thick layer of mulch around the plants can help to keep them healthier and more resistant to disease. With proper care and maintenance, you can grow healthy purple majesty potatoes that are free from common diseases.
