I have a field grown tree coming from a reputable mail order dealer that I’ve used before.
I’d appreciate suggestions for a soil mix for a Dawn Redwood. I seem to read conflicting information in various places. It appears to like acidic soils- should I include any Kanuma in the mix?
I have many soil components my garage: Akadama, Kanuma, Turface, OptiSorb (never used this), Red Lava, Pumice and Bark.
Just unsure of percentages of Lava, Pumice and other components!
