Wisteria grows like mad so I guess there is gonna be a lot of cutting around it in the summer.
And after flowering I will do some minor carving on the lower trunk.
Once it´s alive and taken care of properly its safe to play with it I´d say, I see it in our garden where the mother tree grows like weed sprouting from the ground and trunk as well every few weeks
Not really, temperatures are around 0°C at night, supposed to get warmer next week to about 6 at night, but I store this wisteria in unheated room in my house and it is warmer there than outside.
I will probably wait another month before I move it outside (depending on weather).
