Seed Potatoes: Getting the most out of your purchase

Planting Potato seed

Pre-planting treatment, proper timing, and plant spacing should be understood before planting.

Pre-sprouting

4-6 weeks prior to planting seed potatoes, place them in a warm dark area. 2 weeks later expose them to light. This will cause the eyes to sprout. The sprouted potatoes are ready to plant. This step is not necessary but will lead to better success.

How to plant potato seeds:

Plant seed potatoes as cut pieces or whole potatoes two inches deep, space 12 inches apart with rows spaced 30-36" apart.

When to plant potato seeds

Plant when soil temperature is 50 degrees . This is often 2-3 weeks before your last frost. Planting in cold wet soil will slow growth or rot the tubers.

Where to plant potato seeds

Potatoes can be grown in the ground, containers, grow bags or raised beds.

Grow in full sun. Fertile well-drained soil is preferred. Slightly acidic soil is helpful; however, they are adaptable to a wide range of growing conditions.

How to grow and care for your potato plants

Fertilizing potatoes

Fertilize potatoes when they begin to grow and again when they bloom.

Hilling Potatoes

Start hilling plants when they are 8-10 inches tall. Repeat every few weeks until 8 inches of soil is mounded. If not hilling, mulch to protect tubers from being exposed to sunlight.

Weeding

Light cultivation, hilling and mulching help keep weed growth suppressed and increase yield.

Watering

After plants emerge keep your crop consistently moist until plants start to turn yellow. Discontinue after that.

Harvesting potatoes

For new potatoes, gently dig around the plants starting 60 days after plant emerges from soil. Harvest at golf ball size. For Storage, dig potatoes 2 weeks after foliage dies back.

Storage

Store in cool, humid location and dark location.

Controlling pest and disease

Successful pest and disease control starts with purchasing only "Certified Seed Potatoes", tilling in or removing the previous year's debris, rotating crop planting areas and keeping the garden weed free.

Colorado potato beetles are common pest and can be controlled with several products Gurney's offers. Gurney's super-lite insect barrier keeps insects off the plants. Oil Away Supreme suffocates the beetle eggs before they hatch. Pyola and Shield-All will kill adults and larvae. Surround at Home Crop Protectant creates a particulate barrier that pest find irritating. Most of these products work for other potato pest like flea beetles, leaf hoppers and aphids.
