How to prune lilac

When to prune lilacs

Lilac needs to be pruned in the spring every year, and some dense branches, dead branches and diseased branches need to be cut off. After 3-4 years of cultivation, the branches need to be pruned significantly, and the trunk should be cut 30 cm from the ground. In this way, it will bloom luxuriantly in the next year. Another pruning is required during the growing season to facilitate the differentiation of flower buds.

How to prune lilac branches

Lilac is dormant in winter, so the stems and leaves at the bottom need to be cut off, and the old flower heads need to be cut off after they begin to wither. After flowering, some stems and leaves that have grown too long or overgrown need to be trimmed immediately to a suitable height, which is more conducive to its growth.

Cuttings of lilac pruning branches

Lilac should be propagated by cuttings one month after flowering. It requires suitable soil and relatively sturdy branches as cuttings. It needs to be soaked in clean water for a day before propagation to allow it to have sufficient moisture. A humid environment is needed during the propagation. It will take root about 20 days after propagation.

Lilac pruning and shaping

When caring for lilac, some flower stems that have grown too long need to be cut off so that it can have a more beautiful shape. In addition, some diseased and insect-infested branches and dead branches should be pruned in time, which can not only reduce nutrient consumption, but also ensure good growth. In addition, the dead flowers should be cut off in time after flowering.

How to prune lilac to make it grow faster

During the growing period of lilac, the tillers should be removed in time, and the new shoots should be kept within 60 cm. In addition, the overly long branches should be appropriately pruned, and more upright new shoots should be retained, because upright new shoots are conducive to the accumulation of nutrients and can also differentiate flower buds in summer.

How to prune lilac to make it bloom

Lilac needs to be budded before flowering to control the number of leaf buds. It needs to be shaped and pruned before germination to remove dense branches, thin branches, diseased and insect-infested branches, so that the crown can be ventilated and light-permeable, and to promote the flowering of new shoots in the crown. After germination, 2 to 3 sprouting leaf buds should be left on the lower part of the branches, and the flower buds should be retained to allow them to bloom.

Tips for pruning lilac
