How to Manage Pests
Pests in Gardens and Landscapes
Leaves on plants that have been overwatered become yellow and drop. Trees may later become predisposed
to root and crown rots.
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.
