Hebe Renovation query
In our jungle of a back garden, we have inherited a massive, 2m+ high Hebe salicfolia.
At the moment it's in flower and looks lovely, except there's a big...hole? in the side of it. So now it kind of looks like the Death Star.
I made my husband look into the hole to make sure it wasn't a wasp nest or something (I'm brave like that! ), but he said he couldn't see anything. So what I'm thinking is it probably is falling apart under it's own weight?
Do you think it's worth trying to renovate it? Prune it back really hard this year and see what happens? It's too big for the garden anyway, so it will need to be cut back... Or do I cut my losses, and just scrap the whole plant?
