Cutting Back Perennial Salvia
I have two to three year old perennial Salvia with blue spires. They have grown tall and are falling over by its own weight. Should I cut them back or separate them? They are also attracting about ten bumble bees per plant, so it's difficult to work with them. Any ideas would be appreciated.
If the plants were mine, I'd either prune or separate. Pruning would probably be easiest. Can you burn either dry leaves or twine string to make smoke, thus discouraging the bbees while you work. They are valuable pollinators, don't kill them!
