Can I cut my dwarf lilac bushes back to 10 (?) inches from the ground in the fall?

Question

My dwarf Korean lilacs are about 10 years old and getting quite bushy. I am never going to do the 1/3 a year kind of pruning. So can I just cut them way back this fall? If so how far back?

Answer 1

Yes, you can definitely cut back the entire thing for restorative pruning! Early spring is the best time for this, and you can cut down to about 8 or 10 inches from the ground.
