How do I know when to dig potatoes?
When to Harvest Potatoes. For winter storage, it's best to let the plant and the weather tell you when to harvest potatoes. Wait until the tops of the vines have died before you begin harvesting. Potatoes are tubers and you want your plant to store as much of that flavorful starch as possible.
Wait until all the foliage of the plant has withered and died back before harvesting mature potatoes. After the foliage has died, dig up a potato from one or two plants and rub the skin of the potato with your fingers. The skin of a potato that is ready for harvest won't scrub off easily.
- Before planting, Sarah and Danielle cut the potatoes into chunks, with at least two “eyes” (buds) per piece. Then they dig a planting trench 6 inches deep, fill the trench with 3 inches of compost, and place the seed potatoes in the trench cut side down, 6 to 8 inches apart.
- Potatoes can be grown anywhere from sea level to 13,000 feet. The growing time for red potatoes can be from 70 to 120 days, depending on the variety you choose to plant and what size you like your potatoes. There are early, medium- and late-maturing varieties.
- Potatoes may be planted as soon as the ground can be worked in the early spring, but keep soil temperatures in mind. Potato plants will not begin to grow until the soil temperature has reached 45 degrees F. The soil should be moist, but not water-logged.
