Hilling is an essential technique in potato cultivation. This involves gathering soil around the base of the plants to promote tuber growth and minimize exposure to sunlight.
When to Hill
Begin hilling when your potato plants reach about 6-8 inches in height. Perform this process a couple of times during the growing season.
How to Hill
Use a hoe or your hands to mound soil around the base of the plants, creating a ridge. This protects developing tubers and encourages them to grow larger.
Harvesting Your Potatoes
After diligently caring for your potato plants, the time will eventually come to collect the fruits of your labor.
Signs of Maturity
Potatoes can be harvested at different times depending on your preference:
- New Potatoes: For younger, smaller potatoes, wait until the plants are flowering. These can be harvested in about 60-70 days.
- Mature Potatoes: For larger, storage-worthy potatoes, wait until the plants have died back and the leaves have turned yellow. This typically occurs 90-120 days after planting.
How to Harvest
- Prepare Your Tools: Use a garden fork or spade to loosen the soil around your potato plants.
- Gently Lift: Carefully lift the plants, starting from the outer edges and working your way in. Take care not to damage the tubers.
- Cleaning: Brush off excess soil but avoid washing them, as moisture can lead to rot during storage.
Storing Your Harvest
Once your potatoes are harvested, proper storage is key to enjoying them long-term.
Storage Conditions
- Cool and Dark Space: Store potatoes in a dark, cool, and dry area, ideally between 45-50°F (7-10°C). A basement or cellar often works best.
- Air Circulation: Use burlap or paper bags instead of plastic to allow for airflow, preventing moisture build-up.
Monitoring Your Storage Potatoes
Regularly check for any signs of spoilage or sprouting and remove affected potatoes promptly to maintain the quality of your stored crop.
