potting mixtures
any advise on potting mixtures,I have read in the RHS encyclopedia use 3
parts bark chippings,1 pt perlite,1 pt fine charcoal.Can the charcoal be
ordinary barbeque charcoal washed,can the bark chippings be the sort you get
from garden centres (for mulching)or does it have to be sterilized?
thanks keith
