hi I'm Lou Mayer is a certified arborist and today we're talking trees clients often ask us what can we do over the winter to protect our trees and shrubs for the oncoming season that question often leads into a discussion on dormant oils certain insects will lay their eggs in the fall on certain trees and shrubs those eggs will overwinter and in the spring larvae will emerge if left unmanaged over time these larvae can cause significant damage to the trees and shrubs in your landscape applying dormant oil will help control overwintering insect populations by coding the insects spirals effectively smothering future larvae but the oils are less toxic to beneficial insects such as ladybugs as well as birds and mammals dormant oil is an easy and cost-effective solution but there are a few things to keep in mind when considering it as an option one timing dormant oils should not be applied
