Here are my tips for growing great potatoes:

Site, soil type:

Potatoes like soil that has medium fertility; not extremely high, nor void of nutrients.

Use light soil to give tubers freedom to grow.

Grow in full sun.

Planting requirements:

Potatoes can be planted at 40 degree air temperature or three weeks before last frost.   Plant three inches deep, 12 inches apart.

Plant pieces or whole potatoes that have at least two eyes.

If cutting potato pieces, leave them in a warm place to dry for 2-3 days.  This prevents rot in the ground.

Nutrition/Fertilizer needs:

Apply fertilizer that is low in nitrogen and high in phosphorus like rock phosphate.  Rock phosphate is available to the plants faster than bone meal (which also has phosphorus).

Overfeeding results in “hollow heart”, holes in the center of the potatoes.

Water needs:

Keep moist.  More water means more tubers.

Other tips:

Mulch potatoes.  Add leaves or straw as plants grow, starting when they are about six inches tall.  Mulch discourages weeds, retains moisture, and will give more potato producing real estate since potatoes grow up from the seed.     Mulch also prevents potatoes from turning green.  Green potatoes are toxic.  Green results from exposure to light.

Pre-sprouting (chitting) gives potatoes a head start.  Put potatoes in flats up to two tubers deep.  Put in a warm bright place for up to two weeks.  Sprouts will start growing and will produce tiny green leaves near the tuber.  Then plant as usual.

A soil Ph below 6 will discourage scab.  However, scab doesn’t affect edibility or flavor of potatoes.

Although not routinely recommended, I have successfully saved and subsequently grown my own seed potatoes.

Red Gold is a potato variety that I consider perfect.  It tastes wonderful, produces early, and has a very high yield.

This table at Fedco/Moose Tubers gives excellent information on potato varieties.
