When And How To Prune Endless Summer Hydrangea And Russian Sage
Question From: Livonia, Michigan, United States
Q: Advise on trimming the following plants in the spring...Endless Summer Hydrangea and the Russian Sage...last spring my Landscaper cut back the stems to about 6" above the soil. All of the flowers on the Hydrangea were close to the lowest leave ring or level??? The Russian Sage were slow in coming up but took off and have been in full flower since the beginning of August!
Endless Summer Hydrangeas do not need pruning unless you want to shorten the shrub. They should be pruned no later than the end of August. I cut my Russian Sage back to about 8 to 12 inches when new growth just begins to appear. It is a late starter. Best And Happy Yardening, Nancy.
