I found a rose at the nursery last fall with a nice trunk and good nebari.
I cut about 1/2 the foliage back this spring and will do so again after this growing season.
I didn't want to prune too hard while the roots recovered.
After I prune it again, the foliage should be much more in scale with the trunk.
I think its good to have a rose bonsai to act as a bug sink.
The bugs tend to stay away from everything else and just focus on the rose.
It's fine by me... then I only have to spray 1 "tree".
