How to Manage Pests

Pests in Gardens and Landscapes

Watering potatoes

Examine your soil visually and with your hands to determine the need for additional water. Potatoes are shallow rooted and need light, frequent watering at least once a week with drip or furrow irrigation during the growing season to maintain uniform moisture content in the soil.

Proper irrigation will keep your plants vigorous. If soil is alternately wet and dry, the potatoes can become rough and knobby.
