Russian sage (Perovskia)

Question

Should I cut this back after the summer? How far?

Answer 1

Russian sage should be cut back just before leafing out next spring. You will be able to see buds starting to swell. Cut back to 6 inches, making sure there are several live buds left on the stem. Large, budless stems should be cut to the ground. Since it can get tall and a bit floppy, some recommend cutting again to 6 inches when the plant is 12 inches tall. The trimmings are good deer/rabbit repellant. I place them over emerging tulips.
