The best time for pruning lilac bushes is right after their flowering has ceased.

This allows new shoots plenty of time to develop the next season of blooms. Pruning lilacs too late can kill young developing buds. Jul 08, If you can't stand the look of your old lilac or you just want a quicker approach, you can take the drastic measure of cutting back the entire plant to about 6 to 8 inches above the ground in the early spring.

Fertilize the plant with compost or a balanced fertilizer to prompt new growth. As soon as the lilac bush's flowers are dead, trim each flower stem back to the leaves, removing all trace of the flowers.

I think it needs more sun but I did not know that they bloom on new wood.

This step stops the lilac from using its energy to make seeds. Shrub lilacs and bush lilacs are short and compact. Tree lilacs can grow up to 25 feet ( m.) high and have a tree-like appearance, but their many stems tend to get them classified as bushes. They are not technically trees, but they get big enough that you can treat them as if they are.

Timing is the Decisive Factor in Pruning Lilacs. If you want to have your blooms next year, it is crucial to prune in those first few weeks after blooming ends.

Ideally, this is when you would do maintenance pruning each year. But I get so lazy busy, I end up with a ten foot bush with ten blooms on top.
