I have a LARGE ash tree (40" diameter) which has concrete around 1/4 of the base. Will the treatment be effective if I can only apply around 2/3s of the base?
It is best if Bayer Advanced 12 Month Tree and Shrub is used around the entire tree. However, if you cannot apply around the tree, it can be just be applied to the area that is accessible.
