What are they? Spider mites are tiny pests that feed on may plants by sucking juices from leaves and buds.
Symptoms: Often times, the foilage will be yellowing, especially in evergreens. They can also produce a speckeled, salt and pepper appearance on leaves, along with a distortion to leaves and flowers. Spider mites are very tiny, making it difficult to see them. Although, webbing can occur but in most cases the damage itself is what’s noticed.
Recommended Treatment: A good tree/shrub program is ideal in limiting the damage spider mites can cause. This would include the spring and fall fertilization for overall health and vigor of the tree; along with two insect and disease applications.
