The lilac blooms mainly in May and is one of the typical spring plants. With its wonderful fragrance and great color, it presents its full splendor in home gardens.

The lilac has been avoided by many gardeners in the past few years because the charm of the cottage garden did not fit into the modern ambience of new gardens. Today the lilac adorns various gardens. Because in recent years, numerous new lilac varieties have come onto the market that not only impress with their unique fragrance, but also with new colors and a long flowering period. Basically, the lilac is one of the olive trees and likes to stand in the sun or in the partial shade of a windy place in the garden. We have put together an overview of what you should consider when planting, cutting and propagating lilac.

This is what the lilac looks like

Over time, the lilac, a deciduous shrub, grows into a large shrub or rarely into a small tree. Depending on the type of lilac, the size varies greatly between one and up to seven meters. The shape of the leaves ranges from oval and round to egg or heart-shaped.

The overall appearance is very compact and upright. The flower buds are at the ends of the branches that formed in the previous year and open depending on the region between the end of April and mid-May. The opened flowers then exude their floral scent. The flowering period is over at the beginning of June. Then the lilac forms fruit capsules with seeds.

Lilacs and varieties

The lilac was brought to the Viennese court by an Austrian from Turkey in 1565 and from there it entered the gardens of Central Europe. Towards the end of the 19th century, a large variety of different varieties emerged mainly through breeding in a French tree nursery. There are now varieties of noble lilac with improved properties. Not only are they more compact and robust, their flowers often have two colors.

Today there are more than 20 species and over 100 varieties. When making a purchase decision, you shouldn't just look at the beautiful flowers. Because many lilac bushes can be many meters high, which looks unattractive in small gardens.

a) The lilac (Syringa vulgaris)

The noble lilac is a deciduous, upright growing shrub and grows to an average of three to four meters, some varieties even up to six meters high. Its flowers appear from mid-May and have the typical floral lilac scent.

b) The hyacinth lilac (Syringa hyacinthiflora)

The flowers of the hyacinth lilac appear earlier than the lilac. Their overall appearance is often bushy and rich.

b) The Hungarian lilac (Syringa josiflexa josikaea)

The Hungarian lilac is about 2.5 meters high and has long, strongly fragrant individual flowers. The unopened flowers are particularly beautiful. This type of lilac is also very suitable for smaller gardens or for keeping in pots.

c) The Canadian lilac (Syringa x prestoniae and Syringa x josiflexa)

This type of lilac is particularly resistant to extreme winter hardiness. It only begins to bloom two to three weeks after the lilac and exudes its own special fragrance. The Canadian lilac can reach a total height of 2.5 meters. This lilac is also particularly suitable for smaller gardens or for keeping pots.

d) The royal lilac (Syringa chinensis)

The royal lilac is one of the most beautiful types of lilac and over time it forms round bushes up to four meters high. Overall, this type of lilac is very undemanding and can also be used as a windbreak hedge.

The right location and soil for the lilac

In general, all lilacs prefer a sunny spot and even tolerate dry heat. You can also put the lilac in the shade, but there is no dense crown and significantly fewer flowers. Noble lilacs are also particularly windproof and are therefore often used as a wind-protecting hedge in northern Germany.

When it comes to the right floor, the lilac is quite tolerant overall and can also cope with less favorable floors. The lilac does not tolerate soil compaction or waterlogging at all. Depending on the type of lilac, the needs of the lilac behave very differently. While noble lilac prefers a nutritious, rather dry clay soil with a high lime content, Preston lilac, for example, grows best on lime-poor and moist soils.

How to care for the lilac

The lilac is a very easy to care for plant that does not need irrigation in dry summers. The lilac only needs additional nutrients in the form of fertilizer horn chips if it is planted on sandy soils. Optionally, you can improve the storage capacity for water and nutrients by adding a thin layer of ripe compost to the tree slice in spring.

Cut lilac

Already in the previous year the lilac was forming its flower buds. Only at the end of May should you cut the lilac back a little so as not to senselessly reduce the bloom. When cutting, all faded panicles should be removed if possible. This prevents the formation of seeds and stimulates the lilac to form new buds.

a) The right cut to maintain the flowers

Immediately after flowering, the withered flowers can be cut off with secateurs. However, make sure that no young shoots are injured. Because these are already forming flower buds for the coming season.

But even without pruning, lilacs form new flowers into old age. Over time, however, older branches will age and inside the crown the side branches will die. As a result, the shrub becomes bare from the inside out over the years, and the crown branches outward. To prevent this, about every third flower shoot should be cut back a little more after flowering.

Tip: If you simply cut off a nice bouquet every now and then during flowering, the old age can automatically be avoided.

b) Rejuvenate old lilacs by pruning

You can breathe new life into old shrubs by cutting back the main branches to a length of 40 to 60 centimeters. It is best to spread the taper cut over a period of two to three years. In this way you avoid the complete failure of a flower.

c) Raising young lilacs with pruning

If you want to grow a lilac as a single-stemmed tree, all secondary branches and side shoots must be removed from young plants.

Multiply lilac

You can grow new young plants from your favorite lilac using various methods:

a) Root runners

The easiest way to propagate the lilac is through the roots. Especially the noble lilac trains plenty of it. Simply prick the foothills with a spade in spring or autumn and plant them in another desired location.

However, this procedure does not work with all noble varieties, such as the "Memory of Ludwig Späth". The reason for this is that this variety is often propagated by young seedlings of the wild species, the root of which then carries the flower colors and properties of wild lilac.

b) In vitro propagation

That is why the so-called in-vitro propagation has prevailed in recent years. With this method, new plants are grown from very small pieces of tissue on a special nutrient medium. The advantage here is that the offspring are root-safe and thus the foothills can also reproduce correctly.

c) Multiplication of stickwood

This method is particularly suitable for the Hungarian lilac. You cut off pieces of pencil length from young shoots. These should end with a pair of buds at the top and bottom. On the lower side, a narrow, about two centimeter long strip of bark is cut off. Then you put the stick in the bed of loose and humus rich soil and cover the whole with a fleece tunnel.

d) cuttings

Especially weak growing dwarf lilac and the Preston hybrid is almost exclusively propagated by cuttings. The head or partial cuttings are cut off in May or June with at least three leaf nodes. Then remove the three lower leaves and put them in a mixture of growing soil, sand and algae lime.

e) Sow lilac

The propagation of lilac by sowing is a simple method. For this purpose, dry fruit stalks are harvested in October, shaken out in a bucket and the seeds are separated from the other components of the fruit with a sieve. Then you sow the seeds in the seed box with seed soil. You can leave the box outside in the shade until the following year. Make sure that the earth does not dry out. Only in January will the nursery box be covered and placed in an unheated greenhouse. The seeds then start to germinate there. The seedlings can be pricked into pots in spring and then placed in autumn.

These pests and diseases can harm your lilac

The lilac leafminer or lilac moth is a typical pest that can appear on the lilac bush. The infestation can be recognized on brown leaves in May. Usually picking the larvae by hand can help. Aphids or mildew can also occur. But these diseases don't do much harm.
