I ordered these Satsuki bare rooted and they came in great shape and health. I potted them immediately into a mix of Landscaper’s Pride, expanded shale, play sand, and perlite. I tested the sand and expanded shale in a cup of white vinegar to see if they would dissolve and thankfully they did not. If they did they could make the soil more alkaline, which I definitely want to stay away from.
