Special conversation about own-rooted varietal lilacs. Unfortunately, common lilac varieties reproduce very poorly by cuttings. An adult lilac bush at a certain age begins to produce shoots, which are varietal. And this is a great boon for the gardener: it becomes possible to plant a whole lilac garden, especially if there are several varieties. How to deal with young growth?
It is necessary to closely monitor the growth of shoots in early summer: as soon as they grow up to 10-15 cm, they are watered, dug up and cut off from the mother bush. As a rule, they have few roots, while you can cut root cuttings, they can have a certain number of thin suction roots, they are also planted for growing in furrows.
But it so happens that the stems of the shoots have time to lignify and form a good lobe of roots, such a plant should also be planted for growing, it will quickly reach the size required for planting in a permanent place. Furrows are prepared in advance for planting shoots in a fairly bright place, but a lacy shadow under the crowns of trees is also acceptable.

It is useful to fill the furrows with compost, and complete long-acting AVA fertilizer with nitrogen will not interfere (one teaspoon per meter of the furrow is mixed with soil - this is enough for the whole season). The separated growth with a part of the rhizome is laid out in furrows, watered abundantly and covered with earth, tightly squeezing the root for tight retention in the soil. From above they mulch with loose earth, even dry. There will be enough moisture inside the planting for at least a week - until the next visit to the garden.
If the weather is very hot, it is worth shading the planting overgrown with lilacs with lutrasil, newspaper, gauze, net - whatever you have at hand. After all, the separated plant parts have practically no suction roots, and it is necessary to create comfortable conditions for them, water the first time once a week and then mulch with mowed grass, sawdust, dry soil - any loose material to preserve soil moisture and speedy root formation. Overgrowing plants can be pinched off so that the wood has time to mature by winter, but usually the shoots do not grow too quickly in the first season.
In the spring of the second year, young lilacs are fed with full fertilizer (Kemira, nitroammofosk, AVA with nitrogen). In case of insufficient growth, feeding is repeated, but since the end of June, nitrogen is not added. By this time, the growth of lilacs ends. In the middle of summer, it will be appropriate to apply AVA powder or granules around the perimeter of the bush for the successful wintering of lilacs. With adequate nutrition, the death of seedlings during the winter practically does not happen.

In the second year of life in the planted shoots, the tops are trimmed and the shoots are pinched off to form a branched crown. In what form you will grow lilacs - you decide. It can be formed in a bush (multi-stem) or standard form (in one trunk and with a branched crown, which is created by repeatedly pinching the growing shoots). I will only note that the standard form of lilac is less common, but this is one of the most elegant solo plants in the garden.
With a large amount of source material, it is quite possible to form both bush and standard specimens - there will be a place for everyone. In a permanent place, coppice lilacs are planted in the second - third year of cultivation. For successful flowering, lilac needs a bright, high place (groundwater at a distance of 0.8–1 m from the earth's surface), fertile soil. Put 0.5-1 tbsp in the landing pit. spoon of AVA granules and humus, compost.
Green cuttings - the most difficult method of propagation - need to be described in detail.
