Hi, we have just bought a new house with a big overgrown garden. It coUldnt be more different from my old little garden that comprised mainly of perennial flowers. There are lots of well established but overgrown shrubs that I don't know what to do with.
I am after some tips on the best way to prune a lilac at this time of year it has over 30 stems and is approaching 20 feet tall. It's huge. I was thinking of cutting 1/3 of it to the ground. I've just been out to look at it and this might be tricky as the stems are really close to each other.
Any advise would be great.
