|We have several large Cleyera shrubs. A couple have had their leaves turn brown and fall off. One shrub appears dead and an adjacent one is doing the same thing.
Any idea what is happening to them !!
|Cleyera can sometimes be infested with southern red spider mites. These tiny pests feed by sucking out the plant's sap, causing the leaves to turn a stippled yellowish, then eventually turn brown and dry up. They are most active in the spring and fall, becoming inactive in the heat of summer. If you hold a piece of white paper below some leaves and tap on them, you may see the tiny mites moving around on the paper. Also you often see fine webbing between the leaves on heavily infested plants. If these mites have caused the damage, you may not see evidence of them at this point since they are not very active now. The time to treat for them is at the end of the summer as they become more active again. Spray with insecticidal soap three times at 7-10 day intervals.|
