How to Manage Pests

Pests in Gardens and Landscapes

Overwatering

Leaves on plants that have been overwatered become yellow and drop. Trees may later become predisposed to root and crown rots.

Solutions

Maintain a good irrigation program. Allow soil to dry partially before watering. Then irrigate to wet soil at least 2 feet deep. Trees may need irrigation about every 7 to 14 days during the summer, depending on soil type and weather conditions. Don't plant ferns, annual flowers, or plants that need lots of water around trees. Be sure to keep the trunk dry.
