Shrub rose falling over
I have three of these that were here when I bought my house last fall. I think they're some sort of shrub rose.
It's hard to see in the picture, but the right half of the plant is starting to lean pretty significantly forward. Looks otherwise healthy, so I suspect it's just gotten too heavy to quickly to support it's own weight. I didn't prune it this winter.
What's the best thing to do? Prune back heavily even though it's pretty active? Add some sort of support?
