Treating Radiata Pine bark for potting mixes
I usually post on the bromeliad forums, but not being able to get an answer to my question I'm now asking for help from orchid growers.
Does anyone know what the professionals use to treat new Radiata Pine bark with before using it in orchid mixes.
I know it's best to use old bark in preference to new as I've been told the new bark is too high in acid and resins.
I also know you can buy bark which is pre-treated to overcome this problem but I can't find out what its treated with.
Can anyone help with an answer.
Thanks in advance
