Hi...I am in Missoula...Three large...large...large! green cottonwoods were blown over( rooted) in my yard a few weeks back(79mph winds and wet spring). Not wanting these beautiful trees to be turned into firewood I have been searching for the best outcome for them and stumbled upon permies.com....insert( halaluya's and angelic harp music). Obviously the answer will be to use them in a hugelkulture type way. My question is do i need to cut them down to smaller pieces...did I mention they are quite large? haha! This task seems over whelming......but i know its possible.......thank you for your help+information.
