After first bloom, can you cut back salvia significantly since new growth is sprouting up from the roots at the base?

Question

I dead head after first bloom and typically they will bloom again. Just wondering if plant will continue to grow up from the base if I cut them back to the point where new growth is appearing.

Answer 1

Yes, they will spread, and keep forming new growth from the base. You can trim back to promote this newer growth. They may be a little late to flower, but it will improve the health of the plant.
