I have a maple tree in the front yard that the boys planted as a Mother's Day present about thirty years ago. I am going to take several cuttings and grow a tree for each of them and one for us just in case we move sometime. I am not sure the exact species, but definitely not Trident or any kind of Japanese maple. It does not have the red stems I associate with red maple and it turns glorious yellow in the fall, so whatever that would be.
The guide to propagating from cuttings on the Empire here says to use a layer of pumice and then "Bonsai soil" which is sort of non-specific. Is that Akadama and the usual mix of lava rock? It doesn't seem that that would be what the cutting needs to grow roots. Other online sources give about every combination of potting soil, peat moss, sand, perlite, etc., you can imagine, but I sort of want to go with what the Empire recommends, or rather what people here actually do.
What soil mix have you used that has grown lots of cuttings, particularly maple? If you wanted 5 cuttings to live, how many would you make?
