I have a cherry plum tree that was RAVAGED by bark beetles last year and is now dead. So I was getting ready to cut it down and it dawned on me, omg this bark is PERFECT! So I used a knife to pry 2 buckets full of bark off the tree. Here is my question. What perparation is required before using bark? does it need to be soaked to leech out the tanins in the bark? Baked? Bleached? It is all fairly thin bark, about 1/4" thick.
