Crop Culture
Potatoes are a versatile and staple crop that prefer cool, well-drained soil with a pH of 5.0-6.0. They require full sun and consistent moisture. Before planting, enrich the soil with compost or a balanced fertilizer. Avoid using fresh manure or high-nitrogen fertilizers, as they can promote foliage growth at the expense of tubers.
Potatoes are typically grown from seed potatoes, which are small potato tubers or pieces of tubers, each with one or two eyes (buds).
Planting
Cut seed potatoes into pieces, each with at least one eye. Let the cut pieces dry for a day or two before planting to prevent rot. Plant them about 3-4 inches deep and 12 inches apart in rows spaced 24-36 inches apart. As the plants grow, hill soil around the stems to cover the developing tubers and prevent them from being exposed to sunlight.

Diseases, Insects, and Weeds
Common pests include Colorado potato beetles and aphids. Diseases like potato blight, scab, and rot can be problematic. Use appropriate organic or chemical controls for pests and practice crop rotation to prevent diseases. Mulching helps in weed control and conserving soil moisture.
Harvesting
Potatoes can be harvested when the foliage begins to die back. For new potatoes, harvest a few tubers earlier when the plants are flowering. Carefully dig around the plants to avoid damaging the tubers. After harvesting, let the potatoes cure for a few days in a cool, dark place to toughen up their skins.
Storage and Preservation
Store cured potatoes in a cool, dark, and well-ventilated place. Properly stored, potatoes can last several months. Avoid storing potatoes near onions, as they can hasten spoilage.
