How to Grow Potatoes 05:02

Joe Lamp'l shows how to plant, grow and harvest potatoes.

Yellow flesh potatoes, which get their color from a natural plant pigment called anthoxanthin, are much more popular in Europe than in America but are becoming more widely grown for their color, firm texture, and luscious flavor. Like blue and purple varieties, they are loaded with antioxidants, making them a healthier choice than white-flesh varieties. Yellow potatoes also tend to be somewhat sweeter and require less flavorings than the starchier white varieties.

Yellow Potato Varieties

Yukon Gold is by far the most popular yellow potato. The medium to large oval tubers have a thin gold skin and light yellow flesh, and the eyes sometimes have a pinkish color. Other yellow varieties include the heirloom Yellow Finn with its unique pear shape, Delta Gold, Bintje, and Saginaw Gold

Charlotte is a relatively small, round yellow potato with creamy yellow skin and light yellow flesh. Peanut Fingerling is a small, teardrop-shaped potato with a nutty flavor. Its early harvest makes it ideal for climates with short cool seasons, or for growing in containers.

Growing Yellow Potatoes

Yellow potato plants need seven or eight hours of sunshine, well-drained moist soil, and good fertility. Plant potatoes during cool weather when there is no danger of a freeze but when temperatures remain below the mid-80s: higher temperatures reduce tuber formation.

Find “seed” potatoes online, but be sure to order early while supplies last. Cut seed potatoes into small pieces, each with one or two small leaf bud “eyes.” Plant three inches deep and a foot or so apart in rows, hills, raised beds, or containers. Work in an all-purpose fertilizer before planting and add an extra bit around the sides of plants a month after plants start growing.

Potato tubers grow on short stolons on lower stems, which can turn green if exposed to sunlight. Avoid this and its bitter flavors and the buildup of a poisonous plant alkaloid called solanine by piling soil or thick mulch around small plants, repeating as needed until six or eight inches of lower stems are buried.

Harvesting Potatoes

Small “early” tubers can be dug by hand about three months after planting, but for larger, mature tubers wait another month or when plants begin to turn yellow. Dig carefully to avoid cuts and bruises, gently brushing off soil instead of washing which can lead to decay during storage.

Store mature tubers in a cool, dry, dark area for a few weeks to three or four months, checking regularly for shriveling and decay.
