Wisteria - amethyst falls
Im in the uk and bought a small roughly 6inch plant off ebay that arrived in december, i left it on my kitchen windowsill and just gave it a small amount of water once a week, now it has grown to about 2 feet tall. Not sure if i should have kept it outside now but need advice on what to do now.

I would put it outside during the day and bring it in at night for a week to harden it off. If you have a prolonged hard frost I would keep it in all day. It is hardy but the new growth is not. Does the label say if it is Wistera frutescens or sinensis/japonica? Amethyst Falls is normally the American version, frutescens.

Yes the lable says it is a strain of the american version frutescens ( in small letters )

Thanks guys. When do i prune it? Autumn?

No, when it's mature, it'll need pruning twice a year - in Jan/Feb and July/August.
The RHS site has excellent step-by-step advice on how to prune Wisteria.
Welcome to GoY, by the way. :-)
