When & How to Plant Seed Potatoes

Overview

Potatoes planted in the spring can yield a bountiful harvest of tubers in the fall. Properly stored, potatoes keep well and can be the accompaniment to or basis for many satisfying meals. Potatoes are grown from seed potatoes--potatoes which are beginning to sprout. You can plant potatoes from a bag you purchase at the grocery store, but you'll get the best results by planting potatoes sold specifically for seed.

Step 1

Test the temperature of your garden soil. If the soil is above 40 degrees it is safe to plant potatoes. Potatoes need a long growing season, so plant as early in the spring as possible.

Step 2

Dig a shallow trench in the garden, about 4inches deep and wide enough to accommodate the seed potatoes. Space trenches 3 feet apart.

Step 3

Apply a line of fertilizer or compost in the trench and mix it with the soil. Use a fertilizer for potatoes or a rich compost.

Step 4

Plant whole potatoes or cut each potato into several chunks with a knife, each piece containing two or three eyes. Lay them in the trench about 12 inches apart and mound soil over the potatoes about two inches deep .

Step 5

Water regularly, keeping the soil moist but not soggy. As plants emerge from the soil, continue to mound soil with a hoe around the plant stem.

Step 6

Harvest potatoes two weeks after the plants begin to wither and yellow in the fall.
