Growing Potatoes From Potatoes. ... However, if you have some potatoes that are beginning to sprout (the "eyes" have swollen, whitish shoots beginning to develop), simply plant a piece of the sprouting potato in the ground or in a roomy pot covered with 3 inches of soil.

Potatoes always do best in full sun. They are aggressively rooting plants, and we find that they will produce the best crop when planted in a light, loose, well-drained soil. Potatoes prefer a slightly acid soil with a PH of 5.0 to 7.0. Fortunately potatoes are very adaptable and will almost always produce a respectable crop, even when the soil conditions and growing seasons are less than perfect.

Cutting Potatoes Before Planting

A week or two before your planting date, set your seed potatoes in an area where they will be exposed to light and temperatures between 60-70 degrees F. This will begin the sprouting process. A day or two before planting, use a sharp, clean knife to slice the larger seed potatoes into smaller pieces. Each piece should be approximately 2 inches square, and must contain at least 1 or 2 eyes or buds. Plant smaller potatoes whole. A good rule of thumb is to plant potatoes whole if they are smaller in size than a golf ball. In a day or so your seed will form a thick callous over the cuts, which will help prevent rotting.

We find that potatoes are best grown in rows. To begin with, dig a trench that is 6-8 inches deep. Plant each piece of potato (cut side down, with the eyes pointing up) every 12-15 inches, with the rows spaced 3 feet apart. seedsavers

Potato seed is what gardeners call small pieces of cut-up whole potato tubers, each with a growing bud that will form a new potato plant.

Before planting, cut whole seed potatoes into pieces a little larger than a large egg, each with one or two “eye” buds on them. If possible, spread them out to dry indoors for a day or two to let the cut areas heal over to prevent rotting in cold, wet soils. diynetwork
