Q.my Wisteria is dying
In June I pruned the plant which is about eight years old and had the most blooms ever. But after blooms finished new leaves have wilted and the plant seems to be dead. I have watered it regularly. Could a cold wind have scorched it, as we live on the coast and do get strong winds at times. But plant has never reacted in this way before.

It is possible, if it is cold at this time. After pruning, they can be a bit sensitive. Overwatering will not be good for it though. Only water if the soil is dry down to about 5 inches or so or when it has not rained for weeks. They are somewhat drought tolerant. Overwatering will cause infection.
It will be best to wait until spring to take action, as then you will know whether it is actually injured or if it just needed to recover from the pruning.
