Wilting leaves on my wisteria
Hello My white flower wisteria has never had flowers and has always had shriveled wiltering leaves. It is green and sprouts new shoots etc, but its leaves always shrivel. Can you tell me why? It has been planted for about 6 years now and I have given it plenty of fertilizers etc, but it still has this problem. It gets morning sun not afternoon.

Have you inspected the vines for insects such as aphids or scale? They are sucking insects and damage can include curling leaves.
Regarding the no flowers, it may be getting too much fertilizer or not enough sun. Since they are aggressive vines, they don't need much fertilizer if any. Also too much nitrogen will prevent blooms. Full sun yields the most blooms.
Was your plant grown from seeds or cuttings? If so, it can take years to bloom.
