Beni Maiko grows to about the same height and spread, perhaps just a little smaller, as Acer palmatum dissectum 'Ornatum' which I bought the other day. I need to try and protect it from scorching wind but it will tolerate partial shade or sun, apparently. It got knocked about a little bit at the garden centre and long roots were hanging out of the bottom of the pot. I repotted it, disturbing the roots as little as possible, in MiracleGro All Purpose. I know a lot of websites recommend using John Innes but the truth of the matter is that the bags are so heavy, I cannot handle them. I occasionally, only very occasionally, mix loamy garden soil with MiracleGro.
