Pest management: Potato cultural tips, pests, and diseases
When to plant: February–April (possibly May)
- Potatoes usually mature 90—120 days after planting (depending on the variety).
- You can harvest a few at a time and leave the rest until you are ready to eat them. When you "rob" potatoes—for smaller, more tender potatoes—be careful not to damage the plant.
- Harvest remaining potatoes when the plants wilt and turn brown.
- As the plants grow, mound the soil around the plants until at least 6" of the plants are covered.
- Maintain soil cover for tubers as they expand. Tubers exposed to light may have bitter-tasting green areas and should not be eaten.
- Potatoes are sensitive to soil moisture. Maintain a consistent soil moisture as much as possible.
