Shiiiiiit....
Nature's little bonsai artists?
That is part one. Watch all 3.
In one of them, cows, goats, or other muntjac like creatures are brought up as a huge positive in the creation of killer Ass deciduous Yamadori.
Sounds like a bloody gold mine!
Oh and this.....
Of rooting chunks of willow.
I see people dunk em in water and it works but you get roots everywhere.
Waste of time and energy.
I would drill a piece of dollar store cutting board to the base, so the roots go straight out, and rig the thing to float with only that first half inch in the water...
Or hell, sphagnum up around the whole cut and keep that Just soaking.
I'm thinking a couple pieces of Styrofoam and some boards....dirtbag shit.
But you'll get strong Ass roots where you need em, nice ones too.
