Lilac is not leafing
Our lilac bushes were totally covered with beautiful fragrant blooms this year but now that the blooms are gone the bushes don't seem to be leafing out. One bush has what looks to be a new (this year) leafy growth coming up the center, towering over the main plant but the rest of the leafing is sparse. How long should it be between blooming and full leafing?
