How to take care of Russian sage

Russian sage is a fragrant perennial that can grow up to 4 feet tall and 3 feet wide. July through September, the Russian sage shrub displays small lavender blue flowers the full length of thin silver colored arching stems. This woody shrub is cold hardy to USDA zone 5. Caring for Russian sage through pruning, especially if the shrub is overgrown, can be handled in the spring.

Plant Russian sage in full sun anytime of the year though spring and fall are optimal. Choose a location where the soil drains well. Russian sage will benefit from at least 10 percent organic material mixed in with the soil when planting. Set multiple plants at least 24 inches apart. Water well after planting and then about every 10 days unless it rains. Apply about 2 inches of mulch such as pine chips.

Allow Russian sage to grow during the year unassisted. Fertilizing the shrub is not necessary, but an all-purpose water-soluble fertilizer can be applied if desired. 

Cut the stems of Russian sage to within 6 inches of the ground each year in early spring.
