Q.

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

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?

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.
