newbie potted blueberry question about fertilizer
I have one potted blueberry bush from last year that is all budded up and doing well. Still hasn't leafed out but lots of green on the branches. Just bought another a few days ago. I remember reading somewhere on here that you can give them a mixture of water and white vinegar to help with their ph requirements instead of a fertilizer...could someone tell me a little more about this? Like how much white vinegar-to-water ratio and how often I should do this? Thank you!
