Preparing for breeding
Cuttings are cut from young shoots. It is important that the tree is healthy and flexible. The best time for slicing is spring. Cuttings can be harvested during and after flowering. It should be cut early in the morning from the middle of the crown. It is desirable that there are 2-3 short internodes on the branch.
Cuttings harvested from thick branches do not root. When cutting cuttings, you need to make sure that there are 2 buds on one cuttings. It should be cut at a distance of about 0.5 cm from the lower kidney and above 1 cm from the upper kidney.
The length of the cutting should be about 10-14 cm. It is important to know that 70-80% of annual shoots of the total should not be cut off. It is not recommended to cut cuttings from the same shoot. The leaves from the lower node must be removed.
The cut must be at an oblique angle, and be right at the top. For this purpose, a sharpened knife or pruner should be used, so that tissue can be less injured. Shorten the leaf plates by half. After cutting, it is recommended to place the cuttings in the Epin-extra stimulator for 16-20 hours. Further, when planting, the cuttings must be rinsed under running water.
Necessary conditions for growing lilacs
Lilac is a thermophilic plant that grows well in areas with adequate lighting. The shrub grows, so you need to plant in a free area. If you plant it in the shade, then you will not have to expect lush flowers. In such a place, the lilac will stretch upwards and bloom weakly.
If the place is swampy or periodically low-lying areas are flooded, then this is not a suitable place for planting shrubs. The plant will not grow. Lilac does not like drafts and stagnant moisture, this must be taken into account when growing. The site must be protected from cold winds.
For normal growth and development of the shrub, the soil must be fertile and moderately moist, as well as acidity close to neutral. Planting lilacs on heavy and acidic soils should be avoided. If the soil is acidic, then it can be neutralized using dolomite flour or ash. In this case, all the time it will be necessary to check the reaction of the soil.
In addition, it is important to take into account the groundwater level - no closer than 1.5 m from the surface. Lilacs need to provide good drainage. If you create the necessary conditions for lilac, then it will develop well, bloom every year and do not require special care.
Planting cuttings: technology
For good rooting, cuttings are best planted in a greenhouse. If there is no greenhouse, then you can get by with plastic bottles with a capacity of 5 liters. It is important to prepare the soil for planting: peat is mixed with sand in a 1: 1 ratio. If the sand is replaced with perlite, then moisture will be better retained and the soil will "breathe".
The prepared place for planting the cuttings should be well shed with a fungicide solution. As a result, fungal infections of the cuttings can be avoided. The use of stimulants is recommended, as the cuttings do not take root well.
The procedure for planting a lilac stalk: make a depression in the soil, place the stalk and deepen the lower node. The distance between each cuttings should be about 5 cm. First, a drainage layer of rubble or expanded clay should be laid on the bottom, then rotted manure and a soil mixture on top.
Next, cover the cuttings with plastic or plastic bottles. The cuttings are covered with a translucent cloth between the two layers of the film. This is necessary for shading the cuttings. When properly planted, they will only emerge after 40-60 days.
Lilac care after planting cuttings
After planting, spray the cuttings with a spray bottle. It is important to ensure that the cuttings do not dry out, so they should be sprayed 2-3 times a day. It is also necessary to ensure the appropriate humidity - 100%. The optimum temperature for rooting cuttings is 23-26 degrees. It is important not to forget to ventilate the cuttings.
In order to prevent the formation of mold on the leaves, it is recommended to spray it with a solution of potassium permanganate once a week. If the cuttings are rooted, then they can be planted in a school. For late rooting, it is better to leave the cuttings in the cuttings. A separate bed should be located in a lighted and quiet area of the garden with fertile soil. Rooted cuttings should be planted at a distance of 25-35 cm.
To grow young seedlings, you should choose a warm place. After rooting, airing is carried out for several hours in the evening. After a month, the airing is increased and gradually the shelter is completely removed. For the winter, young plants must be covered with a layer of dry leaves or peat.
In the fall, you may notice darkening of the leaves, but this should not be feared. The main thing is that the kidneys are alive. Lilac bloom can be expected in 4-5 years. You should regularly water, feed and loosen the soil of the seedlings. Sanitary pruning should be done every spring. This is a mandatory procedure, otherwise the shoots will weaken. Pruning should also be done after flowering.
Remove inflorescences, small and thin shoots. You can not break off the shrub, so you can damage the buds, which will not bloom next year. Every year with the onset of spring, it is recommended to feed the lilacs with nitrogen fertilizers. You can also use ash and organic fertilizers and apply them during the budding period. Phosphorus-potassium fertilizers should be applied in the fall every 2-3 years. These are the most essential requirements for caring for lilacs.
