So you can multiply your lilac yourself

The Content Of The Article:

The easiest way to multiply lilac by root shoots. Above all, the wild species of the noble lilac (Syringa vulgaris) makes plenty of it. The shoots are struck with the spade in autumn or spring and replanted at the desired location. For noble varieties such as 'memory of Ludwig Sp├Ąth' or 'Charles Jolie', however, this method does not always produce the desired result. Reason: The varieties are often propagated by upgrading to young seedlings of the wild species - therefore, the Wurzelausl├Ąufer wear the flower colors and properties of wild lilac. In recent years, however, has increasingly prevailed in the varieties of noble lilac, the so-called in vitro propagation. In the laboratory, tiny new pieces of tissue from the dividing tissue are used on a special nutrient medium to grow new plants. The advantage of this method is that the offspring are rootless - and then can propagate naturally over footholds also sortenecht. Experience so far, however, shows that in the laboratory cloned noble lilac form only a very small extent Wurzelausl├Ąufer.

Walk on spade

Multiply lilac

By foothills lilac is the easiest to multiply. Simply prick them in the fall with a sharp spade (left), pull them out of the ground (right) and plant them in another place

Simple, but a lot of failure: plywood

The propagation through plywood is another very simple method. It is suitable for the Chinese lilac (Syringa x chinensis), the bow lilac (Syringa reflexa) and the Hungarian lilac (Syringa josikaea). The noble lilac, however, the success rate is very low. Even under optimal conditions, only every tenth plywood grows. Anyone who wants to multiply the precious lilac from the wood of pegs should cut off pencil-length pieces as early as the autumn after leaf fall from well-developed annual shoots, which end up with a pair of buds at the top and bottom. At the bottom, a so-called wound cut is made laterally by separating a narrow bark strip about two centimeters long. Then the stick wood is placed in a half-shady bed with loose, very humus-rich soil and covered with a fleece tunnel. Incidentally, the best growth rates are shown by the annual shoots of young lilac cultivars propagated by in vitro culture (see above).

Preston lilac 'Elinor'

Preston lilacs such as 'Elinor' (Syringa x prestoniae) are propagated mainly by cuttings, some varieties also by Steckholz

Multiply lilac by cuttings

The propagation of cuttings is possible with all varieties for which the plywood method is also suitable. Low-growing dwarf lilacs such as Syringa x meyeri 'Palibin', Syringa microphylla and the Preston hybrids (Syringa x prestoniae) are usually propagated exclusively by cuttings. In the case of the noble lilac, however, the method of cutting is also very difficult and works best again with young mother plants from in vitro culture. In all lilacs head or partial cuttings with at least three leaf knots are cut from the uncultivated shoots already in May / June at the time of flowering. The lower leaves are removed and the cuttings wounded laterally. It is plugged into a permeable potting soil-sand mixture, which should be enriched with some algal lime. Even under foil or in the covered and heated cultivation box, the rooting of precious lilac takes a long time and the rooted cuttings do not drift until the next year.

Dwarf lilacs

Dwarf lilacs such as Syringa x meyeri 'Palibin' can be picked from cuttings

Sow lilac

Sowing lilac is relatively easy: Harvest the dry fruit stalks in October, shake them in a bucket and separate the fine seeds with a sieve from the remaining fruit components. Then they are sown in seed boxes with potting soil, left open until next year in a shady, cool place outside, and careful that the soil does not dry out. In January, the boxes are then covered and placed in an unheated greenhouse, where the seeds germinate quite reliably. The young seedlings can be piked in pots in the spring and planted in the autumn.

Note that the noble varieties of the various lilacs as well as the hybrids can not be propagated by sowing properly. The result can only be seen after a few years, when the seed-propagated plants flower for the first time. With a bit of luck, you have also created a new variety with a particularly beautiful flower.

Propagation through refinement

This propagation method used to be common in the cultivars of the noble lilac. However, it is increasingly displaced by the in vitro culture, because it can thereby achieve root-correct plants, which also form hardly foothills.In July, the various varieties are refined by grafting on one to two-year-old, pencil-like seedlings of the wild species, which were already planted outdoors in the autumn. With the seedling documents all buds should be removed already in the late winter up to the height of the later processing station. Alternatively, the refinement by copulation in late winter is possible. For this purpose, you can also use rootstones of the Hungarian lilac (Syringa josikaea) as rootstock, as it does not form so many roots. The refinements are then planted out in the open just below a non-woven tunnel.
