Q.Would very aggressive pruning in July on a 93 degree day on Cotoneaster (hedge type) destroy the plant?
Our landscaper here in NW IL did a very aggressive pruning on the Cotoneasters in our community on a July 94 degree day. The plants into the fall were very sorry looking. They said wait til spring they will be fine. Well it’s spring and most of them are dry and dead looking. Can you shed some light on this please
We recommend pruning early in spring, though pruning of dead or diseased branches can be done anytime.
