Winter Pruning Wisteria
January or February is a good time to winter prune your wisteria. This will give you a chance to 'train' the plant where you want it for the summer, will encourage the plant to bloom, and should not damage the plant as it is 'dormant' at this time of year.
Start by removing dead or diseased wood from the plant. Then remove any branches that may be crossing and rubbing against one another.
Cut back sideshoots to two buds (you should be able to see the small buds). If required, tie shoots to support frameworks or onto a trellis.
The RHS recommends that no more than 25% of the total framework should be removed in any one year, otherwise the plant will grow lots of leaves and less flowers. If you need to remove more, do it over a number of years. Always use sharp and clean secatuers.
Pruning over winter will encourage good flowering in summer. Enjoy your garden
