How to Manage Pests

Pests in Gardens and Landscapes

Watering lettuce

Lettuce crops can be grown under drip, sprinkler, or furrow irrigation. Examine your soil visually and with your hands to determine the need for additional water. Water deeply by drip or furrow irrigation to encourage deep rooting. If you allow water to seep through only to the top few inches of your soil, root growth will be stunted. Keep adequate moisture in the deeper soil layers even when plants are small. Deep moisture is harder to replace later in the growing season without overirrigating.

Proper irrigation will keep your plants vigorous and help protect them from thrips damage.
