Frost Proof Gardenia
I have 3 frost proof gardenias planted (approx. ) 3 years ago near my back entrance. This year for no apparent reason, one of the shrubs looks like it is dying. The other two are fine. The one that is dying looks like one whole side of it is drying up and the leaves turned yellow and are falling off. These plants did wonderful up until this year. What have I done to kill my shrub?
