Eastern Tent Caterpillar is often destructive to apples, crabapples and cotoneaster – all members of the Rose family. Reese, our Plant Health Care Manager, is on the lookout for telltale signs of this pest in the landscape and is prepared to spot spray with Bt, Bacillis thuringiensis, a selective insecticide approved for organic programs. You may see tent-like webbing and loss of leaves near the tips of branches, a sure sign of a caterpillar infestation. Let Kim know and we can arrange for your Plant Health Care visit.
Hydrangea Leaf Tier loves to stitch the new leaves of ‘Annabelle’ hydrangea together and cocoon inside. We open the leaves and blast the plant with a spray of insecticidal soap to combat this pest.
A complimentary method of control is our soil amending program in the fall. Insects don’t like to dwell in a soil with the Phosphorus levels in balance and are much less numerous!
