By now all knows that willowbranches are easily rooted. But have never seen if a large trunk could develop roots.
Sadly I didn´t took any pictures of the 5 logs i got from the large branch.
I puted them on water for a time until i saw small white tips of roots comming out from the barch-piece that was submerged in the water. Only 2 grew new branches from the better places. The other I planted back in the ground, to become new trees. I gave one away and the last i saved for myself.
Some carving will be required in the future but for now it will grow freely.
