Hi all
First post so apologies if my question is a little daft.

As I am off for a few days, and the weather is looking decent, am I OK giving some of the shrubs I have acquired a decent prune. They are very well established (20 years or so) but have been left for a couple of years and so are quite over grown.

If I do not do it now then I may not get chance again till Easter
Thanks
Lee
