I have Tauntoni yews(Taxus Tauntoni) and Browni yews which keep turning
yellow & brown and dying whereas the daisies in the same area seem to be
florishing and spreading like weeds. Is this because of the local soil
condition. Do the yews need more acidity? Would some fertilizing help?
I live in Michigan, the soil is clayey and the area gets plenty of sun
Any help is appreciated.
