Acidic Soil for Heuchera
I have just planted 5 Heuchera and have six more coming in Sept. I thought I had done the research, but just noticed on "Hosta Direct" they recommend soil PH to be 5.8-6.2, Mildly Acidic. My soil is right at 7. I have amended clay soil, with lots of compost, do you think I need to add an acidifier to my soil before I plant the rest?
