Q.Pussy willow
I have a mature pussy willow in my garden. Midsummer last year the leaves turned brown and dropped off prematurely. Now March and no catkins have appeared. There are a few branches that look like new growth but very few. Should I cut it right back to where there is new growth or is it too late and I have lost it completely? In West Yorkshire.
That is a strange event for an established Pussy Willow.
Did you have a dry period? Lack of moisture could be the reason.
I certainly would go ahead and prune done the plant, a hard prune.
Check the moisture level in the soil. If your having dry weather, I would also apply some hardwood mulch to help with moisture control.
