How to Grow Potato Plants


Potato plants are an easy-to-grow plant, adaptable to many different soil types. Potato plants do prefer a soil with a pH between 5.2 to 5.5, as this prevents potato scab, according to the University of New Hampshire Cooperative Extension. Potatoes are planted early in the year, between March and early April. Mid-season varieties are planted as late as the first of July.

Step 1

Purchase seed potatoes from your local garden center and place them in a cool place until two weeks before planting recommends UNH Extension. Put the potatoes out in normal light, high humidity and at room temperature to "green sprout" them, turning the seed every four to five days to develop even sprouts.

Step 2

Cut tubers from the potatoes that are 1 1/2 to 2 inches in diameter. Cut the tuber so that it has at least one sprout, or "eye".

Step 3

Till your seed bed to a depth of 8 to 10 inches recommends Ohio State University to ensure proper growth. Fertilize the soil with a 10-10-10 (nitrogen-phosphorus-potassium) fertilizer at 3 pounds per 100 square feet, and work it into the soil.

Step 4

Plant the tubers 10 to 12 inches apart between 1 and 3 inches deep recommends the Illinois Cooperative Extension. Space the rows 24 to 36 inches apart. Add a layer of mulch on top of the covered potatoes to ensure warmth is kept in the soil.

Step 5

Mound soil around sprouting potato plants by hoeing the soil towards the plants according to Illinois Cooperative Extension. Soil may be piled between 4 to 6 inches by the summer to prevent sun-scorched tubers.
