How to trim lilac flowers to make them look beautiful

When is the right time to prune lilacs?

Lilac pruning is generally done before budding in spring, usually before potting. The pruned branches can be propagated by cuttings.

Tips for pruning lilacs

Thinning: Thinning should be done after the leaves fall every year, mainly to remove diseased and insect-infested branches, dead branches, weak branches, inner branches, overlapping branches, and leggy branches that affect growth and appearance; all small side branches under the main branches need to be cut off; old large branches should also be cut off to keep uniform gaps between the remaining main branches and a moderate density.

Shortening: Shortening is a light pruning, mainly to prune plants that do not need to be kept for seeds, thin out the overly dense branches in the inner part, increase ventilation and light transmittance, and accelerate the germination of new branches and the formation of flower buds.

Pruning branches and leaves: Lilacs require a high degree of thinning. Diseased and insect-infested branches, weak branches, overlapping branches, and leggy branches should be pruned after the leaves fall each year. The top buds should be topped when they differentiate into flower buds.
