Why do we prune shrub roses?
Dear Garden Folk
I have 2 lovely shrub roses by the name of 'Lovely Fairy' (not The Fairy)
I know that by to cutting back dead and diseased canes the goodness in the plant is rerouted to the healthy canes. I also know to cut back flowers that have come and for the same reason
But, I also know (I think I know) that cutting her back will change, not only change her shape but also invigorate her and what I donÃ¢ÂÂt know is how/why this happens
Share with me.
Thanks so much!
