Need acidic soil for Fargesias bamboo?
Hi everyone, first time posting and first time bamboo grower. It's in the 40s here at night and I just received about 10 rhizomes of Fargesias, unknown sub. Lady said hers grow to 12' and she's only about 100 miles west of me. Anyway, they look to be in really good shape. I was reading somewhere that they prefer acidic soil, so I checked my soil and it's pH is about 6 and some places 6.5. What do I add to make it more acidic, or do I really need to? I'm planning on setting the rhizomes later this afternoon when the temps are closer to 60 degrees. As an FYI - these are the first plants to go in my yard and I really need them to hide the not so pretty view of my neighbors homes.
