Our handy friend has cut down 5 trees all out of hand at over 60ft in my neighbours garden. Is there any use for the wood there are tons of trunks along with the canopy which we are busy shredding through a small shredder. I understand we can't burn the wood on wood burning stove due to toxins in the sap. The canopy and small branches are shredded (or in the process) but been told this is too acidic to use as mulch. Are there any other suggestions please.
