Cut lilac - pruning the lilac bush

Lilac tree - wood

Lilac trees or shrubs can be found in many native gardens. In the summer, they delight their viewers in various shades of purple or white, because there are up to 30 different species. An intoxicating scent emanates all of these easy-care trees. Lilac bushes actually bloom best when they are allowed to grow wild. But not always can be dispensed with a pruning. If proper cutting is done on the lilac tree, it will continue to bloom abundantly.

Pruning of different species

Even though there are up to 30 different species of lilac bushes that unfold their flowers in a wide variety of colors, the steps required for a successful pruning are the same for all. Most gardening enthusiasts in the local latitudes enjoy the common lilac, also called Syringa vulgaris, which blooms in white or purple. But there are other types of white over light yellow to light or dark violet. But no matter which lilac is in your own garden, it actually comes without a cut and unfolds its full beauty in wild growth. But the home garden does not always offer enough space and then has to be cut back. But this also succeeds, without the lilac bush to prevent its bloom.
Tip: Lilac is very well suited as a cut flower in the vase. Ideally in the morning cut off so many stems with flowers at an angle, as desired. Leaves are removed for the vase, so that they do not waste unnecessary power and the flower stays beautiful longer.

Ideal time

The lilac bush in its own garden can also receive an annual pruning if it can not get too big due to lack of space. The best time for this is:
  • in late spring or early summer right after flowering
  • then it is already warm enough that the interfaces can dry quickly
  • otherwise fungal attack could threaten
  • if a lilac has to be cut radically due to obsolescence, this can be done year round

Matching tool

Depending on which cut is to be made, the right tool is also needed here. Care should be taken that it is always cleaned and disinfected before work. This prevents germs or bacteria from entering the plant through the interfaces, which could damage it. For this purpose, appropriate disinfectants from the well-stocked trade or even pure alcohol from the pharmacy can be used. The following tool is required:
  • sharp scissors to cut the flowers and soft shoots
  • sharp saw when cut into hard wood
  • a ladder when the tree or bush has grown very tall
Tip: Make sure you have a sharp tool when pruning the lilac bush! Because the tool is out of focus, can cause injury to the cut point. The shoots and old branches must always be cut smoothly and not fraying, otherwise germs and bacteria can penetrate faster into the interface, as this then can not heal well.

Pruning after flowering

An annual pruning after flowering is for the reason of advantage, since the lilac bush after the cut again looks handsome. However, this type of lilac cutting does not have anything to do with a greater flowering power next year, it's a purely visual matter. Also, if you do not want to find many new lilacs in your garden next year, cut off the withered flowers, because otherwise the seeds formed can spread through the wind throughout the garden to the neighbors. For this cut, the procedure is as follows:
  • About a week after the bloom, remove the dried inflorescences
  • The dried flowers above the leaves are removed directly, the shoots remain standing
  • dried, old and dead shoots can also be removed directly at this time
Tip: If the old flowers and at the same time old, withered shoots are removed every year, the hobby gardener otherwise has little work with the lilac. Because in this way, this receives a beautiful shape, the growth can be kept in the frame. Thus, a small annual cut is associated with less work than if a lilac that has become too large due to wild growth has to be cut altogether.

Pruning for reduction

If the lilac bush at its location has become too large, it must be cut back so far that other plants in its vicinity are not hindered in its growth. Even if the branches already grow to the neighbors or on the street, must be traded by a pruning of the lilac bush. The procedure is as follows:
  • Lilac always blooms only on two-year shoots
  • therefore, the flowering may be less after a pruning
  • However, this can also be prevented by the ideal cut
  • Lilac is cut only partially each year
  • For this purpose, one- or two-year-old shoots are left standing on the bush
  • older wood can be removed
  • Always cut directly on a branch crotch
  • leave no stubs

Pruning in case of obsolescence

Lilac bushes and trees can reach a ripe old age. However, it may happen that an old bush no longer shows any flowers. In such a case, the lilac can be rescued by a radical cut:
  • the lilac is ideally cut back to about a meter in the summer, when it is warm enough
  • This pruning can also be done all year round
  • so new shoots can form from below next spring
  • do not cut them back in the next few years
Tip: After the pruning of an obsolescence of the lilac, the hobby gardener needs a lot of patience, because it can take up to two years, until the bush has grown again lush. But it is definitely worth not removing the lilac from the garden just because it has grown old.
A lilac bush in the garden enriches the whole environment with its beguiling scent and its graceful flowers. Especially for hobby gardeners with little time, the easy-care lilac is well suited. Because a cut must always be made only if it is too big. Otherwise, the lilac tree also enjoys no cut every year to new ones with a lush flowering. Especially wild shrubs have the most flowers. However, if you spend a little time each year in the early summer months, you can call it a beautifully formed and flowering lilac shrub or tree.

Worth knowing soon

Since lilac is one of the more tender shrubs, it is important that you use a very sharp cutting tool. If the blade is too dull, it would hurt the bark, which in turn would provide an ideal breeding ground for germs and pathogens. In addition, it would be quite handy if you had a pruning shears at hand. This would simplify the pruning of the stronger branches a lot. And so you perform the pruning:
  1. Remove all sick, dead and old shoots.
  2. Afterwards cut all withered flower shoots. It should remain about three eyes.
  3. Do not cut too much, because otherwise the blooms will probably stay out in the coming season.
  4. When cutting back, make sure you have a uniform growth pattern so that you retain the overall image of the lilac and do not mutilate it.
  5. Also cut all the shoots that are on the trunk of the lilac.

sectional circumference

  • Since lilac often grows very high and wide, it sometimes has to be blended more radically for reasons of space.
  • For this pruning, leave only branches up to a meter high.
  • However, you should not be surprised after such a cut, because the lilac will produce no flowers for at least one season.
  • Such radical editing should therefore only be carried out if absolutely necessary.
  • Therefore, make sure in advance, before you plant a lilac, whether the space is sufficient for this.
Tip: You can also use lilac as a hedgerow plant. But please note from the outset that the individual plants have enough space between them to avoid a radical cut. Because only a blooming lilac brings radiant splendor and a delicate scent into your garden.
