Checked out one of my wisterias today, which is giving me concern. It was on the garage wall when we bought this house in 1972. Over time I trained it over the pergola I built between the garage and our koi pool.
But it eventually came to look more like the Lock Ness Monster and bits started to die off in 2016.
The problem was that the main root was rotting.
So I took some drastic action and removed all the dead wood. I had to re-make the end of the bed.
This left me with one long branch that traveled along the top of the fence between the garage and the house and half covered this pergola, meeting up in the middle with one growing up from the other end.
There were enough layered parts of this to train over the pool pergola last year.
But sadly there seems to be no life in any of it so far this year and there's rot at the base of the one main branch left. Our other four wisterias are doing well.
I'm going to have to make a decision about it if there's no growth showing in a month (I'm pretty sure it's dead, but my wife wants "to give it a chance").
I'm not that bothered, the wisteria on the back of the house can be encouraged to grow along the full length. I'd been pruning it off before.
I'll probable grow about three clematis up this garage wall instead.
Shame, but nothing lasts for ever does it?
