Planting Instructions: Select a sunny location and plant in early spring in the soil. Plant when the soil is workable.
1. Till the soil to a depth of ten or twelve inches.
2. Place one seed potato into the tilled dirt 4-6" deep. Plant this cultivar in a broad well-shaped hill to control late season greening. Then cover with soil.
3. Pull in additional soil as the plants develop. Always be certain the surface tubers are covered with soil. Water potatoes (thoroughly).
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. Resists late blight. Heavy yields in midseason. Mini-tubers have 3-5 eyes each. Plant now, or store in a cool, dry place until you are ready to plant. They'll keep for weeks. NO CUTTING REQUIRED. Just plant one eye per hill.

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 - New young potatoes are harvested when peas are ripe or as the potato plants begin to flower. For storage of full sized potatoes harvest them when the vines turn yellow or have died-back. STORAGE - Keep them in the dark, in a spot where temperatures are about 40 degrees.
Pests or Diseases: All selections compete fair against weeds especially compared to standard Norkotah. They are not sensitive to any major herbicides. Standard insect control measures generally are effective. Three to five fungicide applications may be necessary to control foliar early blight.
Tuberization/bulking: Tuber set is light to medium, high in the hill. Greening may be a problem without good hill management. Tuber bulking occurs in a short interval during early to mid-season at an extremely rapid rate. Russet "Norkotah" is moderately resistant to blackspot and resistant to growth cracks, second growth and hollow heart. Tubers can become large late in the season, so close monitoring is necessary after early August.
