Good point Brian,

I say "for me" also.

For what it's worth, I have been in the nursery business for over 30 years and into bonsai for over 20. I HAVE done the experiments because I have the space and the material. I reached my conclusions with cuttings growing side by side in all manner of various concoctions.

Ideally, "for me" in S. Florida, I find I need to water too much (especially in summer) to use only Turface and found that about 60% works best as stated.

In Maine, I use closer to a 75% mix with equal (summertime) results.

I also found that foliar feeding (north and south) is highly under estimated. Certain ferts sprayed right on the leaves (especially the undersides) are taken in directly and produce very good results.

Cheers,
