Hi guys!
I'm a complete gardening novice 
and I'm a little worried about killing this very old rose bush so I wanted to get some advice before I tackle it. I gave it a light prune this spring but having done a little research I think I need to take it to the ground over the next two years????
It was my grandmother rose it's pushing 50 we think. I really want to salvage it and bring it back to life.
Any tips on how I might go about this? Without killing it!
