Caring for Potato Plants

Watering & Mulching Potatoes

Watering Needs: Keep soil moist but not soggy.
Mulching Benefits:
- Helps retain moisture.
- Prevents weeds and stabilizes soil temperature.

Fertilizing for Higher Yields

Best Fertilizers:
- Organic compost for slow-release nutrients.
- Balanced 10-10-10 fertilizer during early growth.
When to Fertilize:
- Before planting: Mix compost into the soil.
- After sprouting: Apply nitrogen-rich fertilizer.

Hilling Potatoes: What It Is & Why It Matters

Step-by-Step Hilling Guide:
1. When plants reach 6 inches, add soil around stems.
2. Repeat every 2 weeks until plants bloom.
Hilling Benefits:
- Protects tubers from sunlight.
- Encourages more root growth and higher yield.

Harvesting Potatoes

When to Harvest Potatoes

Early Potatoes: Harvest in 10-12 weeks (small, tender potatoes).
Main Crop Potatoes: Harvest in 15-20 weeks (full-size, long-storing potatoes).

How to Harvest Potatoes Without Damaging Them

Use a garden fork and carefully lift soil.
For containers, gently dump the soil and collect potatoes.

Storing & Curing Potatoes for Long Shelf Life

How to Cure Potatoes After Harvesting

Why Curing is Important: Helps potatoes develop a thicker skin for storage.
Best Curing Conditions:
- Store in cool (50°F/10°C), dark place for 1-2 weeks.

Best Ways to Store Potatoes

Ideal Temperature & Humidity:
- 40-50°F (4-10°C) with 90% humidity.
Avoiding Sprouting & Rotting:
- Store in paper bags or mesh baskets.
- Keep away from onions and fruits (release gases that speed sprouting).
