So I’ve was “gifted” a potted wisteria. I say “gifted” but I’d was rather me taking it of someone’s (who didn’t want it cus they couldn’t take proper care) hand in the hope of being able to make a bonsai of it. The tree is young and has seen some rough times. The trunk is split. Foliage seems unhealthy but has new growth. It seems to not have very good drainage but I was told it was transplanted to this pot from the ground this summer.
So my question is what steps do you think I should take to make this in to a healthy bonsai. I don’t have a wisteria myself and never cared for one but seems a fun experiment.
