Wisteria - Pruning

Hello. I was lucky enough to receive a large, 6ft tall Wisteria Sinensis Prolific Blue as a gift recently. I want to grow it in a pot and have planted it up in a 50 litre pot.
I know and understand that they are quite hungry plants and require feeding well, especially in a pot. Also, that regular watering is important. However, I am unsure as to pruning. I would be grateful for advice on when and how to do this.

You need to decide on a framework - standard or espaliered - and suitable supports before you start any pruning as the eventual shape will be a determining factor. Wisteria eventually grow their own framework as the stems mature and harden and become like tree trunks and branches so it needs tying to, rather than twining round, any support which needs to be strong enough to cope.
Here is a guide to pruning which needs doing twice ayear to promote good growth and maximum flowering - https://www.rhs.org.uk/plants/wisteria/pruning-guide
Planting composts only have food for max 90 days so yes, you'll need a generous handful or two of slow release fertiliser every spring and occasional liquid feeds - rose, tomato or seaweed - between regular waterings. The best place for it is in the ground and it will need watering while it gets established and in any dry spells in future springs and summers. Deep watering once a week is better than a daily dribble as it willpenetrate deeper and encourage the rotts to go down rather than stay near the surface and fry in hot weather.
