Q.Lavender bush
We have this huge lavender bush that is getting a bit too big. I don’t want to get rid of it. All the nice leaves and flowers are at the ends of all the branches, on the inside of the bush, it’s very dry and woody. When and how can I trim it so it grows out even better?
Thanks!

Pruning regularly will help prevent the Lavender from becoming woody.
You can rejuvenate a woody plant with some effort.
