I have sprayed small cedars with Crossbow. It appears to affect them, but the sap comes out and seals the tree and then they recover. Any suggestions on how to eradicate them completely?
When trying to control trees that are well established, it often is best to either do a soil drench into the root system with the product, make cuts into the trunk and apply the product directly to the cuts, or cut the tree itself down and apply the product directly and immediately to the freshly cut stump. You may need to use higher application rates to get full control on more established and hardy plant species.
