July

• Early morning is the best time to water gardens and lawns. Water deeply and infrequently.
• Treat for root weevil adults when new feeding damage (notching) is present on foliage.*
• Treat for scale insects emerging from eggs as crawlers. Sticky honeydew and black sooty mold are signs of scale infestation. Look for scale on camellias, holly, maple and rhododendron.*
• Watch for signs of spider mites on arborvitae hedges and spruces. Look for: dusty-looking foliage, loss of green color, and presence of tiny mites. A good preventative is to hose off your plants with water on a weekly basis. Treat with soap or oil when damage is noticed.*

August

• Make compost of lawn clippings and garden plants that are ready to be recycled.
• Control yellow jackets and wasps with traps and lures or by treating nests.*
• Fall webworm webbing appears in ornamentals and shade trees, prune out nests and destroy, or, if necessary, treat.*
• Monitor garden irrigation closely so crops and ornamentals don't dry out.

September

• Plant lawns until October 15 in western Oregon.
