What to do if the lilac in the garden does not bloom

Lilac is the favorite of many gardeners, as with proper care it can please the eye with its bright and lush flowering. The color palette of lilacs can be either light violet or dark violet with white veins. Moreover, the flowers of lilac are white. But what if the lilac does not bloom? The reasons for this failure in the processes of growth and development of the bush, we will understand in this article.

Selection of seedlings

It is necessary to choose planting material with special care, since it will depend on him how many years your lilac will bloom.

Today, there are many ways to breed this lush shrub, but microclonal reproduction is considered the most common method. This method involves the separation from the parent bush top. Further, professional gardeners rooted the top and spread in the markets.

The microclonal method of reproduction is rather complicated, but at the same time, entrepreneurs love it very much, since with this type of reproduction it is possible to obtain a large number of copies in a minimum time. But there is a problem for the consumer.People who buy microclonal saplings often ask questions about why lilac does not bloom if it is already 3 years old or more.

The fact is that such shoots may bloom for the first time only in the fifth or sixth year of life, therefore it is better not to buy them.

The best seedling will be grafted lilac, which will begin to bloom in the second or third year after planting. Experts say that common lilac (grafted) will be the best planting material / Such a shrub can normally grow, grow and bloom for decades. Try to buy planting material only from trusted vendors who have authentic documentation, etc.

Sometimes the reason that the lilac does not bloom can be the wrong planting technology. That is why experienced gardeners devote a lot of time to planting and prepare for it in advance.

Need to choose the right landing site.: well lit by sunlight, protected from drafts and groundwater.

The landing pit needs to be properly processed: its depth should be 40-50 cm, drainage should be done at the bottom (a layer of fine crushed stone with a thickness of 7-10 cm). In addition, take care of fertilizers, which should be the optimal amount - 30 g of superphosphate, 20 kg of humus and 300 g of wood ash. Especially careful to be with nitrogenous fertilizers (we will tell about it a little below).

Soil type

One of the main reasons why lilac stops blooming is the wrong type of soil. It should be noted that this shrub will not be able to normally grow and bloom every year if it is planted on heavy clay soil.

Lilac loves dry type of soil with moderate acidity (6.5-7.5 pH) and mediocre humidity. You should not plant this plant in highly marshy, heavy or overmoistened soil types. Groundwater level at the landing site should be no higher than 1.6 m. The place where lilac grows should not be submerged during periods of melting snow and high rainfall.

The soil for planting should be dry, with an optimal amount of macro and micronutrients. It will be good if, before planting, you pass the ground from the landing site to an examination in the laboratory.

Specialists should establish the level of all necessary minerals in the soil.According to the result of the examination, you will be able to draw conclusions about which elements are in excess and which are in short supply. And if there is no suitable type of soil in your area, then it is better to remove the soil layer (square meter to a depth of 50 cm) and fill in a land suitable for lilac with all the necessary minerals.

In such conditions, with proper care and with regular dressings, the shrub will bloom for many years.

Insufficient lighting

If this lush shrub does not receive enough sunlight in the spring-summer period, then it may not bloom.

Lilac should receive a large amount of solar energy at the moment when it begins to bloom. Therefore, the best place on the site for landing lilacs will be the western or eastern side. It should be noted that in the south of the shrub is better not to plant, as the scorching rays of the sun can cause the young shoots of lilac to dry.

A bad place for normal growth and flowering of shrubs is considered to be the area where spruces and pines grow.They are evergreens and create a lot of shade, so the lilacs may not bloom at all.

Also try not to plant a shrub in a dense garden or between densely standing buildings that create regular shade.

Feed errors

If you follow the wrong technology feeding lilac bush, the flowering process can not wait. A lush crown, large shrub size, enlarged leaves and many young shoots are the first signs that there is a surplus of trace elements of nitrogen in the soil. Nitrogen provokes accelerated growth of plant tissues, while lilac will increase in growth and spend all the nutrients to develop new shoots and leaves, and the flowering process will be absent.

In such cases, you need to stop feeding the soil with nitrogenous fertilizers. Bring urea and ammonium nitrate only once every 2-3 years.

If you have data on the analysis of your soil, then analyze it and draw the appropriate conclusions.With a large excess of nitrogen in the soil, it is necessary to improve its quality. You can carefully remove the top layer of soil and replace it with soil that is poor in nitrogen but rich in superphosphate. In addition, it should be noted that if the soil has a surplus of nitrogen, it is prohibited to feed the plant with humus, chernozem or rotted manure (these fertilizers also contain a proportion of nitrogenous trace elements).

Pruning

For a normal flowering process, the lilac bush should be regularly cut and rejuvenated. If this is not done, then, as in the case of nitrogenous fertilizers, the bush will acquire large sizes, and it simply will not have enough minerals for the flowering process. In addition, an incorrectly pruned (or not pruned at all) lilac bush looks wild and ugly, there is no harmony and pomp in it.

It is necessary to cut the bush in early spring, before the first buds begin to bloom. Shrubs can be formed by two main methods: a bush (ball) or a tree.

To form a bush in the shape of a ball, all shoots should be cut at a height of 12-15 cm from the first bud. After 3-4 years you need to remove all the shoots and leave 10-12 lignified branches, which in a short period of time will give a large number of new shoots - bright and lush blooming.

In order to form a lilac shrub in the form of a tree (also called this type of bouquet), it is necessary to remove all the shoots from large branches, leaving only one, the largest shoot. About 5-6 rows of buds are left on this shoot, and the rest is removed. In addition, do not forget to regularly dig out of the ground and remove the root shoots.

After their removal, the soil around the bush is dug up to a depth of 7-10 cm. The process of pruning a lilac bush is of paramount importance, as a well-groomed and trimmed bush will annually delight you with its lush flowering.

Diseases and pests

Struck by various diseases lilac will not bloom, and this is a fact. Indeed, in the process of defeating a bush by pests, the normal metabolism is disturbed, therefore the leaves begin to dry out and curl. In addition, you can notice dried and twisted inflorescences, which are the first sign of damage to the lilac bush. Usually lilac blooms for 2-3 years after planting, but only if the gardener properly cares for her. However, no matter what disease the shrub is affected, this can be immediately noticed.

The most common lilac diseases are:

1. Whisk (refers to microplasma diseases).
2. Fungal infections: powdery mildew (white spots on the leaves), phyllostiktosis (brown spots appear on the bush), bacterial rot (affects young shoots, as a result of which they begin to rot), heterosporia (holes appear on the leaves)
3. Viral diseases: ring spot or mottled, chlorotic leaf spot.

If you saw on your lilac bush any of the signs of the above diseases, then know that the shrub most likely does not bloom because of pathogenic microorganisms. But besides them, lilac bush can attack larger insects:

• Rosa Cicadas;
• acacia spatula;
• leaf weevil;
• lilac tick;
• molt-motley.

At the first detection of the affected parts of the shrub, you must immediately remove them and burn. Also, as a preventive goal, you need to handle lilac shrub with special chemicals. To protect the shrub from viral lesions will help such means: "Spark", "Aktara", "Fufanon", etc. Spraying the bush for the purpose of prevention is carried out before the start of flowering.

Lilac must be processed twice, relying on the instructions for use of the drug. The second treatment should be 5-7 days after the first.

Effective means in the fight against fungal lesions are: solution of copper or iron vitriol, copper oxychloride, Bordeaux liquid, etc. Processing should be carried out before flowering or after the shrub has dropped all the leaves (late autumn).

Chlorium oxide copper can be treated immediately after flowering shrub (carefully spray each of the leaves and shoots).

No need to despair if this year the lilac did not please you with a lush and fragrant flowering, because you need to learn from your mistakes.Carefully read all the reasons given in this article for why lilac did not bloom, eliminate them, and next year your shrub will surely give you lush flower stalks.
