For drainage layers and newly collected trees
(yamadori). This substrate can be used as a drainage layer in larger bonsai
pots alongside the regular B4Me soil mix, or as an ideal yamadori soil mix, particularly
for hard to root UK native species such as hawthorn, pine, blackthorn and
especially Yew.
Based on my years of collecting and recovering yamadori, large grain pumice is
ideal for encouraging the survival of newly collected trees and has the necessary
blend of aeration and water retention for vigorous rootgrowth.
Contains a large percentage of washed large grain pumice, with additional
expanded clay, bark and BioChar/Activated Charcoal for growing bonsai, designed
by professional bonsai artist Harry Harrington based on many years of
experience.
Grain size 8mm-15mm. Can be used straight from
the bag without sieving, however, I would recommend mixing the soil a little
further in case of settlement during shipping.
Contains a large percentage of washed large
grain pumice, with additional expanded clay, bark and BioChar/Activated
Charcoal with added beneficial bacteria guarding against root rot and
encouraging strong and healthy roots. I would strongly recommend the addition
of around 10% finely chopped live sphagnum moss (not included!).
DO NOT SIEVE FOR FINES
