Title: Transplanting a young lilac
Answered by: Guy Thompson
Mr. Smarty Plants specializes in plants native to the U.S. Your lilac, Syringa, is not a native, although it is very widely grown in American gardens, especially in colder regions, since it needs winter dormancy in order to bloom profusely. My best guess it for you to wait, if posslble, for the leaves to drop as colder weather arrives. It can be safely transplanted at that time. If you must move the plant while still in leaf, stop watering it now to promote dormancy. Dig it up with as much soil as you can manage and place it in a large pot. Water it with rooting hormone. Leave it outside to allow cold weather to force it into full dormancy. Don't let the soil become completely dry until you can transplant it back into the soil at its new destination.
Lilacs do best in slightly alkaline soil. If your soil is acidic, mix a little lime into the soil when you place to lilac back into the ground.
