Having seen some of the Wisteria bonsai’s on my last visit to Japan a few years ago, had been on the lookout for a big trunk, I do have one wisteria which I salvaged from a dig site but that would take ages to put on the amount of girth I was after, nevertheless it continues to grow as a vine where I have let it loose

. Anyway, I found this ad on Marketplace where all it said was they had some plants to give away, went to see what was available and surprise surprise there was this nice strong wisteria which had twined its way up onto a balcony. Got in there around 1 on the afternoon yesterday and by 2:30 I was done, after an hour and a half of back breaking digging I had a pretty strong Wisteria in my hands. Not quite sure about the colour or variety as the owners were just razing the place down after buying it in the not so distant pst, but wisteria it is and as I did t have a pot big enough to hold it ended up getting a 128 litre storage container from Bunnings

two bags of garden soil, two bags of potting mix and one bag of coarse sand. With some help from my little or now not so little helper, got it all planted up. Now the wait for spring.
I had read somewhere that I had to seal wisteria cuts bigger than a pencil as otherwise the heartwood tots, can someone in Melbourne suggest where I can get such a thing and if it is needed?
Any suggestions on potential shaping also much appreciated, I am thinking of it being a big bonsai at a meter or more. Have cut the main trunk at a thick area with reverse taper as it had some branches, plan is to cut it off once the tree grows which should help with the taper as the branch under it is much narrower.
