That's much too risky. The ivy will quickly draw the Roundup deep into it's roots where it will be deposited in close proximity to the tree roots, whereby it will severely damage if not kill the tree. How do you know this? When a plant is growing strongly roundup is drawn down into the plant after it is applied to from the leaves, this is docmentated as part of the way it works and the reason using it on dormant plants is largely a waste of time . Where did you get the bit about it crossing from the ivy roots to the tree roots via the soil? David Does the ivy use the tree sap when it attaches itself so tenaciously to the tree ? IE. is it parasitic ? |
