Bottle brush bush - Thin out new shoots or not?
Surrey, United Kingdom
I had a mature bottle brush bush, but the severe frost last winter killed it. I cut it down in about May, leaving the stump in the ground. There are now (August) about 16 new shoots growing out of the stump, between 1' and 2' tall. They look healthy!
The old plant had just 2 main trunks. Should I leave all the new growth, or thin out the shoots so that it concentrates its energy?
