How important is acidic soil with Annabelle?
I seem to have mixed success with Hydrangeas and, while I think this has more to do with watering incorrectly, I'm also wondering about our highly alkaline soil. The threads here seem to talk about lowering pH as a way to change the color of the bloom. Is it a mistake to even try to grow an hydrangea like "Annabelle" in alkaline soil? I have amended the soil and will try some aluminum sulfate, but wonder if I can alter the soil enough to expect success?
