MITES CAN ATTACK YOUR SHRUBS

The Photinia above is healthy and below it has spider mites


Spider Mites frequently attack Photinia, Boxwood, and Italian Cypress. They can be very hard to see on the leaf. Many times you can shake them off a leaf and onto a white sheet of paper. This makes them easier to see. If you want to verify that is is not just dust, squash a few specks on the paper and try to smear them across the page. A red streak across the page pretty much confirms the spider mites. The leaf above shows the symptomatic, yellow or bronze speckled look on the leaves . Some experts claim a level of control with a hard spray of water to knock the spider mites off the leaves. Oils or a combination of oils and professionally applied insecticides are the most effective measures.
