Planting Potato

Prefers well-drained, light, deep, loose soil, high in organic matter with a pH of 4.8 - 5.5. Potatoes grow best by planting seed potatoes 4 to 6 inches deep and 1 foot apart with 2 to 3 feet between rows; plant cut sides of seed potatoes down and their eyes up. Large potatoes can be cut up to use as seeds it you leave 2 or 3 eyes per piece. When plants are a foot high, mound up soil around them to increase yield, smother weeds and prevent greening.

Growing Potato

Potatoes grow best with plentiful consistent moisture; if dry spell, irrigate heavily then allow the soil to dry out some before routine watering begins again. Mulching around plants will help prevent sun damage and keep the moisture consistent. Apply a fertilizer that is low in nitrogen and high in phosphorus.

Harvesting and Storing Potato

Harvest new potatoes 2 months after planting; eat soon as they will not keep well. Harvest standard varieties when the foliage and vines have dried down or the tubers are full size. Leave the potatoes in a shady spot to dry for a few hours before storing them in a dark place, this allows the skin to set and increase storage ability.

Potato Insect and Disease Information

Hand pick Colorado potato beetles off the plants. Aphids and leaf hoppers can be removed with a hard stream of water; this is best done in early morning to allow maximum time for foliage to dry. Blight and fungus can be controlled avoiding wetting the plant foliage when watering, practice crop rotation, properly space plants for better airflow and eliminate weeds to allow better daytime drying.

Potato Yield Information

Standard potatoes will yield about 10 times the amount planted.
