In order to plant potatoes in the home garden, seed potatoes must first be purchased and made ready for planting. Potatoes are one of the few plants that are not grown from seed, but instead, grown from potatoes saved from the last harvest. Once put into the ground, potatoes take about 100 days to mature and are ready to dig up when the vines die back and turn brown.
Make a trench in the prepared garden space approximately 4 inches deep. This will be the first row for your potatoes.
Create subsequent rows 24 to 36 inches apart.
Sow one seed potato every 12 inches in the trenches.
Cover the potatoes, using the hoe, with the dirt removed from the trench. Potatoes do best when planted 4 inches deep.
