Overall, I think it is pretty clear that while they are planted in a nursery can of a decent size or in the ground- an organic, rich potting medium like nursery potting soil (Miracle Grow, Pro Mix, or whatever you prefer) is fine and probably going to produce the most rapid growth and development. The size of the pot you plant them in will a fret the rate that they grow as well. I will note that only one of them has died, and it was one of the ones planted in a coarser pumice/lava/akadama mix. I am doing a comparison with trident maple seedlings, planted in a variety of "soils" (ranging from potting soil/perlite to turface/grit/bark and pumice/lava/akadama) but as Dave noted, the sample size is pretty small. I haven't seen any significant problems with the root systems after doing this for several years. Does it give me more growth than using a bonsai soil and heavy fertilizer? I have no idea, I do it mainly because it's cheaper. I amend this as needed with standard potting soil for some plants, or more perlite for others. I've stated in other threads that I've had good results using a mix based on a standard bagged nursery container "mix", which isn't really soil but a combination of peat, bark and perlite. However.a mix of potting soil and perlite might give approximately the same porosity? Bark soil conditioner is somewhat more coarse than standard potting soil, right? I haven't been able to find the stuff locally but it sounds like it's just somewhat composted fine bark.so it must start out at least a little more coarse than potting soil.
