How and how to feed the thuja correctly?

Tui are evergreen conifers, so beloved by the owners of cottages and private houses. Some of their varieties are often used to create hedges that hide dwellings from prying eyes and protect them from the wind. When providing quality care for these plants, you can be sure of the density of their crown. Fertilizers play an important role for the growth and development of an evergreen pet.

Absolutely any plant for full development requires a balanced diet. Thuya is no exception here.

Unfortunately, the soil cannot maintain its fertility indefinitely. With each season, the concentration of macro- and microelements in it invariably decreases - some are washed out together with groundwater, and the other is absorbed by the root system of plants. As a result, it turns out that trees and shrubs do not receive the nutrients they need in sufficient quantities, they begin to wither and may even die.

It is easy to recognize the deficiency of certain elements. With a lack of magnesium in thuja, the crown top turns yellow, yellowness begins with a deficiency of potassium, with a lack of iron in the soil on some branches, the needles become whitish. The reduced presence of nitrogen in the soil leads to signs of chlorosis, that is, discoloration of the ephedra, in addition, the growth of new shoots during the growing season is sharply reduced. If the young needles at the ends of the branches turn brown-purple, then this means that your green pet needs to be fed with phosphorus.

Thuja are usually fed in three cases:

• when planting in poor soil in order to saturate with micronutrients;
• to improve the general level of the agricultural background;
• after planting thuja in the spring or when carrying out an autumn transplant.

Thuja must be fed after transplanting - usually this happens in spring or autumn. For a coniferous tree, you need to choose a sunny place or an area with a little partial shade. Despite the fact that thuja is considered a rather unpretentious plant, nevertheless they need to be planted in well-drained and as fertile land as possible. It will be very good if the soil is pre-fertilized with a leafy, sod or humus substrate. In addition, a little sand is additionally introduced into the ground to improve soil permeability and improve root nutrition.

Just before boarding at the bottom of the pit, wood ash should be poured - about 3 kg, as well as 500 g of nitroammophoska or superphosphate.

Immediately after landing the ground must be watered with Epin's solution, for this, 1 ampoule is diluted in 1 liter of water, after which the soil is mulched with crushed pine bark - this retains all the necessary moisture in the summer, and protects the seedling from freezing in winter.

If you plant thuja in poor soil, then you can additionally carry out top dressing in 10-14 days. In this case, fertilizers containing phosphorus and potassium are usually used. In the first year, you do not need to feed the young thuja anymore, otherwise the fragile tree may simply die.

If the plants show signs of disease, then it is possible to carry out spot top dressing in summer, but with the onset of September, fertilization is not done - this will prevent the thuja from preparing for the cold season and in the end will only harm.

The only exception would be mandatory application of complex fertilizers during autumn planting - usually special preparations for conifers, complex formulations and growth biostimulants are suitable for this.

If the land in which the thuja grows is too poor, then some gardeners go for a little trick - they carry out relatively safe fertilizing by means of ordinary soil filling. As a rule, compost and bone meal are used for this in combination with peat. This technique allows you to nourish the ground around the tree with nutrients - they are very easily perceived by thuja and at the same time do not stimulate the increased formation of new shoots at the very end of the growing season.

If necessary, they often resort to liming saline soil.

Fertilizers for thuja should be chosen taking into account such important factors as the general condition of the plant, its age and soil characteristics. Saturation with nutrients is:

• low - less than 1% humus;
• low-income - from 2 to 3% humus;
• medium-income - from 3 to 4% of humus;
• high - 5% humus and more.

To feed their green pets, they usually resort to several types of fertilizers.

1. Complex mixtures for ephedra. They promote high growth and provide a beautiful crown appearance. Experts recommend using such mixtures for feeding thuja, since these plants often tolerate all other nutrient mixtures and finished preparations very poorly.
2. Organic... To nourish the earth with useful substances, gardeners often use peat, all kinds of composts, and manure. As an alternative, so-called green manure or green fertilizers are used - they are optimal for improving the level of the agrophone, do not cause plant growth after the end of the growing season, and therefore do not harm young and adult thujas.
3. Potash... All kinds of potassium salts and potassium chloride have proven to be excellent for feeding all types of coniferous shrubs and trees, including thuja. Lack of potassium in the ground often leads to the fact that trees begin to weaken and completely lose their attractive appearance, and over time, the dying off of the apical shoots begins. It is a widespread and readily available type of fertilizer that is commonly used to optimize crop growth.
4. Nitrogen. These fertilizers are applied before transplanting in those situations when the seedlings are weakened or lagging behind in growth. Nitrogen contributes to the accelerated growth of thuja, therefore, for plants in open ground, it can only be used in spring, but for potted plants, nitrogenous preparations will be ideal winter dressings.
5. Microfertilizers. Such compositions are used for spot feeding with boron, manganese, molybdenum, cobalt, as well as zinc and other useful trace elements, if the soil was not treated with all the necessary micronutrients before planting. Typically, this treatment is carried out in the second year of the plant's life.
6. Bacterial drugs. They are used exclusively in soils with low humus.

Tui require proper feeding, especially at a young age.The fact is that these plants are capable of extracting all the necessary nutrients from the earth only in adulthood - after their root system is finally formed. But even then, your green pets need to be fed from time to time throughout their lives - otherwise they will wither from the gradual depletion of the soil. True, this will have to be done less often than in the stage of active growth.

The first feeding of thuja is done during planting, no other fertilizers are applied this year. The second feeding should be carried out only next spring - in March or April. At this moment, thuja needs a wide variety of useful substances:

• nitrogen;
• magnesium;
• phosphorus;
• calcium;
• potassium;
• iron.

Usually, spring fertilization is carried out with the use of ammonium nitrate, superphosphate, urea, as well as potassium and magnesium mineral complexes of prolonged action. It will be very useful during this period bone flourwhich is considered a good source of calcium.

If the conifers have hardly endured the winter frosts and have suffered from snow and wind, then it is necessary to apply rooting stimulants - Agrecol and Kornevin drugs show themselves best of all.

Using granular formulations fertilizers are distributed around the tree so as not to approach the thuja trunk closer than 15-20 cm, but at the same time and not go beyond the crown projection.

Using water-soluble formulations, for example, superphosphate or ammonium nitrate, they must be diluted in water in full accordance with the instructions on the package.

In the summer, feeding is carried out only in a situation if the land is too poor and the leaves turn yellow. At the same time, biohumuses are used, as well as specialized complexes that simultaneously feed the soil and protect the tree from fungal spores. Experts recommend using the formulations Fitosporin-K and Fitosporin-M (the last letters mean potassium and magnesium, respectively).

Additionally, in the summer, it will be necessary to protect the thuja from the scorching sun and heat. To do this, in the evening, the tree is sprayed with water with the addition of Epin or Zircon. Foliar dressing usually begins in the last decade of April with an interval of every 2-3 weeks.

In conclusion, let us dwell on the main mistakes that plant breeders often make when fertilizing their thujas.

1. Top dressing of ephedra in autumn and winter. It must be remembered that in such a situation, feeding will lead to increased formation of new shoots at the end of the growing season. This will deplete the thuja, and with the onset of winter, it will remain exhausted and, most likely, will not be able to withstand the low temperatures.
2. The use of a large amount of fertilizer. Some people believe that if a seedling grows too slowly, then it lacks mineral and organic substances and therefore needs to be fed. However, this opinion is fundamentally wrong, since the reasons for stunting can be the result of a variety of factors, for example, a lack of sunlight. But an excess of fertilizers leads to the death of roots and the death of the plant, and the death of thuja from excessive fertilizing occurs much more often and faster than from a lack of them.
3. Watering errors. Before applying fertilizer, it is imperative to water the soil abundantly - if the soil is dry, then a solution of mineral substances can lead to a chemical burn of the roots.
