How to Manage Pests

Pests in Gardens and Landscapes

Watering tomatoes

Examine your soil visually and with your hands to determine the need for additional water. Water deeply by drip, furrow, or sprinkler irrigation to encourage deep rooting. However, avoid wetting the foliage or fruit with overhead watering. If you allow water to seep through to the top few inches of your soil only, root growth will be stunted and, in some crops, may cause blossom drop. 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 and sunburn.
