Easy to Grow: SOIL PREPARATION - potatoes grow in just average soil, so a great deal of soil preparation is not really needed. However the addition of some compost or a little peat moss is beneficial. Avoid using fresh manure or lime in the soil where potatoes are to be grown, as it tends to cause scab on the potatoes. The addition of either 5-10-10 or 10-20-20 fertilizer is beneficial. Mix the fertilizer into the planting soil, prior to planting. Till or spade the soil to a depth of ten or twelve inches. Dependably productive, shows good resistance to bothersome scab.
Planting Instructions: CUTTING POTATOES - if the seed potatoes are small to medium sized, plant the whole potato. If they are large sized, you can cut them in half, or quarter them. Each section should have two or three 'growth eyes'. After cutting, let the cut surface callus-over before planting them. SPACING - potatoes can be grown in many different ways. If you have lots of room the cut pieces can be spaced about a foot apart in rows which are spaced two to three feet apart. Then cover with about an inch of soil. Pull in additional soil as the plants develop. Always be certain the surface tubers are covered with soil. Hilling or mounding is another method of growing potatoes. Three or four pieces of potatoes are planted on a mound of soil, pulling in additional soil as the potatoes develop.
WATERING – Black or hollow centers on potatoes is often caused by over-watering. Irregular watering causes irregular shaped or knobby potatoes. As a guideline, water potatoes (thoroughly) weekly during warmer summer weather.
HARVESTING – When the vine dies and falls over, it is time to harvest your blue potatoes. You will want to dig around the plant with a pitchfork carefully so as not to break or puncture the tubers. After harvesting, the blue potatoes can be stored in burlap sacks, baskets, or boxes, and feel free to brush off the excess soil. Your freshly harvested potatoes can be stored at a temperature of 50-60 degrees for a period of two weeks in order to cure them.
When to Plant Outdoors: Select a sunny location and plant in early spring in the soil.
