Ratio for Gritty Mix with only granite/turface
Hello All -
I know I will have to be careful about fertilizing but I am curious:
If I would like to make gritty mix which contains only the screened granite and screened turface so I don't have to worry about the breakdown of the bark.
To retain the about the same water retention/aeration characteristics as the standard gritty mix containing 1:1:1 bark:turface:grit should I -
make a 1:1 ratio of turface to grit or
some other ratio of turface to grit?
