I have had this lilac bush in my backyard for over 25 years. Last year during a very windy storm one piece of the main trunk broke off. Now this spring there is new green growth coming out of the broken piece. Will this new growth turn into new branchs in the year to come. Not sure if lilacs have a life span and this one is just on the way out.
My question is....do I leave all the new green growth..will it eventually fill out this lilac plant again. At the moment the lilac looks very lop sided...hoping it will look better in a few years.
