Lilac Has Last Year’s Flowers

Question

All of last year’s lilac blooms are visible and dried out. I did not prune out the blooms last year, but I did the previous year. I do have new growth and some flowers coming through. Is it too late to prune the old flowers from the bush? When should I do this?

Answer 1

You can cut the old blooms off now. It won't hurt to let them stay, but they are unsightly.
