using Noxall on Bracken fern near ornamental cherry tree #307066
Asked March 14, 2016, 5:51 PM EDT
I would like to permanently kill and remove all the bracken fern in my Garden that has many rocks. I used noxall a few months ago carefully avoiding the ornamental cherry; so far I don't see any new shoots but I want to confirm that there won't be any. I do not want to harm the ornamental cherry tree or Holly or rhododendron. Ultimately the reason for doing this, is to plant this area with more azaleas and/or hydrangeas. I understand that I may need to wait Another year before planting them if I use noxall again. Should I use Knox all again or is there another product that would permanently kill the ferns?
