How to Prune a Russian Sage Plant

Overview

Russian sage is a perennial with light blue flowers and soft grayish-green leaves. This perennial plant is prized for its flowers in mid-summer and for its aromatic foliage. It is serviceable in the garden as a tall border plant or mass planting--or it can be used to form a small hedge. Russian sage does not require much care, and is easily pruned. The correct time to prune Russian sage is after the first hard freeze in the fall. Pruning may also be done in early spring before any new growth has started. Perennials are at their best when they are pruned with care. Pruning stimulates plant growth and enhances blooms. Russian sage should be pruned every year.

Step 1

Place gloves on hands.

Step 2

Clear dead leaves and garbage from around plant. Comb through the plant base with your fingers to remove any dead leaves. Larger perennials tend to collect leaves and garbage. Cleaning them out before pruning insures that you can see where you are cutting.

Step 3

Cut the stems 12 to 18 inches from ground level. Work in small sections until the entire plant is cut back. Sections should be no bigger than 6 square inches. Cut woody, thick stems one or two at a time. Trim the outside stems first, working towards the middle of the plant. Stop trimming when the entire plant is cut back uniformly.

Step 4

Remove and discard any stems that have fallen back into the plant base. The clippings can be placed in a compost bin or burned.
