Treating new pine bark
Does anyone know what the professionals use to treat new pine bark with before using it in brom mixes.
I know it's best to use old in preference to new bark as I'm told the new bark is too high in acid and resins. I also know you can buy bark which is treated to overcome this problem but I can't find out what its treated with.
Can anyone help with an answer.
Thanks in advance, all the best, Nev.
