Help with my August Beauty Gardenia
I planted an August Beauty Gardenia last spring. It did extremely well. Grew large and lush, perfectly green leaves. Now that winter is halfway through season, I have noticed brown on the leaves starting in stripes straight up the middle of the leaf. Then the browning moves outward throughout the entire leaf. Is this winter damage or more that I should worry about???? The whole plant seems to be affected by this..I covered the soil with straw in late fall. I haven't fertilized the gardenia with anything acidic..and it did great through Spring and Summer/Fall.
