Sow and Plant
Grow from sprouting potatoes or seed potatoes, cut into chunks so that each piece has 2 growing "eyes," or sprouts. Let the cut pieces dry for a day before planting 3 inches deep.
Our Garden Planning Tool can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes
Try different types with waxy texture, good with salads. Keep potatoes mulched to protect shallow tubers from sun, which turns them green and bitter.
|
Harvesting
When the plants begin to bloom, feel under the mulch for little new potatoes. Harvest often as the plants begin to die back. Gather potatoes on a cloudy day, and cover them to protect them from exposure to light.
|
Troubleshooting
Yellow-and-black Colorado potato beetles lay eggs on leaf undersides, which hatch into fat red leaf- and flower-eating larvae. Use row covers to exclude them or hand pick off.
