Cowboy for coniferous. CARE FOR SWOWERS IN SUMMER

Ponds in the garden

Why do fertilizers for coniferous and decisive are different? Decorative coniferous plants Do not have a sheet plate like deciduous. They do not need to often feed them, because they do not need to spend a lot of energy to build leaves in spring or for large fruits. Also, most of the coniferous plants usually grow slower than their deciduous relatives.

Furinations and spring fertilizers for coniferous plants are needed only for annual growth, which many and so small.

If you are just going to decorate your garden with coniferous plants, but do not know where they can be found, we recommend paying attention to nursery Ecoplant.. There is a very large assortment of high quality coniferous plants. This can be seen if you go to the nursery site through the banner in the upper left corner of the page.

Spring feeding and fertilizer for coniferous plants. Dates of deposit.
Coniferous plants usually feed 2 times a year - in spring and autumn. In spring feeders (mineral) there may be a very small amount of nitrogen. In the fall of nitrogen, it is impossible to apply!

Early spring, when snow comes down and the soil will dry a little, then make feeding. If this is a compost layer 5-10 cm., Mixed with the upper layer of the soil, then spring feeding quite enough.

Mineral and biohamus fertilizers can be made 2 times for the spring-summer period. The first time after return freezers, and the second time in early June.

What you can not feed and fertilize coniferous plants?
It is impossible coniferous plants in the spring to feed what it fell. For example, you have a feeding for deciduous flowering shrubs or nitrogen feeding, all sorts of azophoski - in no case do not raw them under coniferous plants! It is better to leave coniferous growing on ordinary soil than to overgrown, and then they can die.

It is impossible to feed the manure, especially fresh! If this happened, then wait for the next: adult coniferous plants will hurt for a long time, they will have rooted roots. And young coniferous or dwarfs can die in general - the manure can burn them root system.


Fresh manure contains a lot of nitrogen, this is the cause of a detrimental effect on your coniferous plants.

You can make a slightly coniferous plants well affected, three-year dry humidations. For this, they sprinkle the rolling circle and loosen the soil slightly. But in the case of the appearance of unhealthy yellowness and passing the lower branches, it should be removed - shovel the top layer of the Earth, and then pour a mixture of ordinary sand with sand.

The plants themselves then need to be well pouring to wash the remaining of substances that have adopted on the plant. But you understand, it is better not to risk if you are not sure that it does not contain nitrogen.

Why nitrogen so badly affects coniferous plants?
Nitrogen feeding and fertilizers can cause not only the yellowing of the needles. Most often it can be taken with sollar Burn. Also, nitrogenous fertilizers cause rapid growth of new shoots, which before the winter do not have time to grow.

Young, not overwhelmed shoots at the first frosts just die. And over the Summer, the conifer loses a lot of strength, using a resource for the ripening of young twigs, which again adversely affects the plant itself - the braking of the main growth.

The best fertilizers for coniferous plants are mineral fertilizers, biohumus and compost.

What is the advantage of mineral feeding?
Mineral feeding is best acquired in specialized stores, where you will not be quenched. When buying, be sure to pay attention to the composition, Magnesium must be present in fertilizer.


Magnesium in structure is similar to the natural pigment of chlorophyll, and it is necessary for the normal flow of photosynthesis in the needles.

In fertilizers for conifers there should be enough minerals - phosphorus, potassium, iron, magnesium, potassium, sulfur, calcium and a bit of nitrogen. From trace elements - manganese, copper, zinc, molybdenum, boron, etc.
Otherwise, during a shortage of them, chlorosis can develop - the whims of the needles, but more rapidly passing.

Now there is a huge amount of and a variety of fertilizers for conifers. Popular - Master, Green Guy (granulated), Rockogumin, Biopon, Giley, Agrekol (Liquid), Arvi, Cristal-Spay, Agronova, Combi, Stimit, Compo, etc. There are many of those on which they simply write - "Complex mineral fertilizer for evergreen plants, spring-summer."

If the needle is yellow and you want to buy fertilizer for conifers from yellowing needles, that first carefully review the plant. It may be that the needle is yellow from fungal diseases (spit, rust)! And you will fertilize and hope for recovery. First, do not make thickened planting of coniferous plants, do not put in the shade, and at the end of winter and in the spring, act from the bright sun. Then you do not have to buy what you do not need.

If you do not want to buy specials for conifers, then Take advantage of dolomite flour. It just contains an optimal amount of magnesium so that your coniferous plants always have a healthy and bright needles. But then other microelements of the plant should receive from compost or biohumus.

But the dolomite flour is deoxidizing the earth, therefore, follow the acid that the pH level for conifer was suitable.

Supporting coniferous plants with biohumus.
Biohumus is very good fertilizerAnd they probably can not spoil coniferous plants. Biohumus is land, compost, which worms reworled. This substrate can be bought or get yourself if you start cereferma or vermicomposter. One who is not afraid of worms can quietly devote them and get verma, biohumus and worms for the beds.


Most often, biohumus is bred by water for root feeding, as well as biohumus it is advisable to keep in the shade. In addition to the necessary minerals and trace elements, it still contains a huge number of living microorganisms that have favorably affect the development of plants. Direct Sun microorganisms do not like. Therefore, if you are biohumus just put in a rolling circle, then you will lose half of its value.

Thanks to biohamus feeding of coniferous plants, you will always have healthy, lush trees and bushes. They will increase resistance to any diseases and invasions of pests.

Compost for feeding coniferous plants.
Compost is also a good fertilizer, and it can be done yourself. To get a good compost, you need to mix organic waste, only in the mixture -1 part of nitrogenous organic organics to 25 parts of carbon. A total of 1 cubic meter of heaps should be 1, so compost will not overheat. It periodically needs to be turned over and shedding with water, and even better shed a dissolved biohumus to rather settle with useful microorganisms.


Such compost is well supported by coniferous plants. It is necessary to decompose in the coil zone with a layer of 5-10 cm. And immediately inspire that the coniferous plants receive not only the necessary microelements, minerals, but also the soil microorganisms with them are beneficial.

When and how to disclose conifers from the shelter in the spring? The vaccination of coniferous plants.

Interesting I. unusual varieties coniferous plants.

In the spring, more than ever plants are required feeding. Emitting from winter hibernation, they with new forces begin to grow and for this they need a lot nutrients. And coniferous trees, as well as shrubs here is no exception. How to properly feed coniferous plants in the spring? We will try to answer this question in this article.

First, in no case should not fertilize the coniferous clean manure. Such an excess will simply find it free to burn the root system and destroy the plant. By the way, the raw dung cannot fertilize not only coniferous, but any other garden trees and shrubs. For fertilizer is used only by humus (dung, overwhelming for 3-4 years) and only diluted in water. Many gardeners make the infusion of a cowboy (diluted in water a cow manure) and water so

"Potion" poor plants. I still do not advise you to correct my green pets on such trials, and for feeding use mineral fertilizers.

If we talk directly, then coniferically does not really need a lot of fertilizer, as they do not drop a chew in winter, and in the spring they do not need a lot building material For increasing the green mass, as needed by leaf full trees.

It would be nice if the feeders were balanced precisely for coniferous plants. And be sure to take into account

the composition of the soil on your site. For example, coniferous trees simply do not tolerate a large amount of nitrogen in the soil. This substance stimulates the formation of new gains, but unfortunately, with rapid growth, shoots do not always have time to ripen, which negatively affects their wintering. Most often, such shoots simply die in winter. And if they are some miracle remain alive, without a doubt in the spring and summer, they will strike with chlorosis and other diseases.

That is why pure nitrogen and fertilizers with a high content of nitrogen are better excluded when tuning conifer.

For photosynthesis conifers, magnesium is simply necessary, the atom (as scholars found out) is the kernel of the chlorophyll molecule. The dolomite flour contains magnesium in the desired proportion, and this feeder remarkably affects the photosynthesis of conifers.

The trace elements are very important for the harmonious development of new shoots and chewing, without proper quantity in the soil in the soil in the trees and shrubs, chlorosis begins (whitewashing or picking up.

Feed the coniferous trees and shrubs followed twice a year: in the spring before the beginning of the growing season and in the fall, when the trees go on peace.

Coniferous shrubs and trees are an original and special decoration in the gardens. Recently, the use of green plants is in particular demand for design layouts near the water bodies, creating living ingreders and others. The advantage of conifers over deciduous trees is their durability and reliability. You can enjoy the beauty of colors only a short period during the summer, and enjoy the green and fresh smell of resin coniferous - in winter, in the spring, autumn and summer.

Plant fertilizer: General requirements

Gardeners are often wondering how and how to feed the boys. Many believe that this type of plants does not need to be tuned, due to their sustainability and longevity. After all, the needles grow in the forests and fewer and do not need any human care. but experienced gardeners It is strongly recommended to hold this procedure in order to prevent coniferous diseases. First of all, it is necessary to draw attention to the fact that the procedures for making fertilizer for conifers should be carried out mainly for young plants that have a rapid root root system and strengthened branches.



Features of the life of coniferous breeds

Roughs are unpretentious plantsThey do not require sufficient moisture, light, heat. Feeding performs exceptional function - the growth of the tree. But at the same time, gardeners need to be remembered about their features and sensitivity to chemical and organic fertilizers. It is known that they do not tolerate a large number of nitrogen substances in the soil, responding to it chlorose or the ignition of individual parts.
It does not have much sensitivity to photosynthesis, so it constantly needs the limestone of the Earth (it is better to use dolomite flour). It should also be remembered that the soil should contain as many trace elements as possible, such as potassium, phosphorus, magnesium, etc.

How to improve yield?

We constantly write letters in which lovers of gardeners are experiencing that because of the cold summer this year, poor crops of potatoes, tomatoes, cucumbers, and other vegetables. Last year, we published tips on this. But unfortunately, many were not listened, but some were still applied. Here is a report from our readers, we want to advise plant growth biostimulants that will help increase the harvest to 50-70%.

Compost: Traditional Fertilizer Method

The traditional fertilizer used by the same generation of gardeners and agronomists is compost. Consider best fertilizer For evergreen shrubs. Compost is a forest soil simulator for plants, so they like it. The feeding is carried out by blasting the rolling circle around the tree or shrub, after which the treated earth is sprinkled with a compost (the fertilizer layer should be about 10 cm). After the operation, it is necessary to slightly mix the ground with the compost to provide roots with nutrients.

At the moment, garden shops are ready to offer many types of this fertilizer (among the most common biode, holes). Fertilizer should be made in spring.

Undercalinking conifers: Basic Rules

Biogumus fertilizers

One of the most popular fertilizers - biohumus is an excellent feeding. To date, this substance can be found in different forms: in the form of fluid, granules, powder, etc. If the gardener is dealing with liquids, then the instruction in which the exact proportionality of the dilution of the substance is prescribed is prescribed. After dilution, it is necessary to make small longitudinal wells parallel to plants, where the liquid is poured, after which the ground is buried.
Granulated and powdered fertilizers are entered on the principle of compost: the spreading of fertilizer on the rich circle, after which it is mixed with the soil. The process occurs in two stages: the first is carried out in early spring (As a rule, in April, during the filling of wood by juice of the tree) and the second - at the beginning of summer. In the fall, this fertilizer is extremely not desirable, due to the fears of growth of shoots, which will not be able to fully formed to the cold. The most common fertilizers with biohumus elements are: GreenWorld, Pokon, OMA (granules) and Bona Forte and GreenWorld (liquid fertilizers).

Application of sprays



On the shelves of garden shops you can see special sprays to improve the appearance of evergreen. In addition, their composition contains special trace elements that are necessary for trees. The feeding in this case will be carried out not through the root system, but through a cheva. Plant treatment with spray is carried out in spring and summer, it is desirable in early time day.

Mulching procedure

Experienced gardeners when careing coniferous trees Use not only feeding with fertilizers, but also special material "Mulch" (most actively applied in the USA). The types of "mulch" may be inorganic substances (stones, pebbles, rubbing) and organic (elements of natural decay: sawdust, hay, humus).

Mulch performs a lot of useful functions for plants. It prevents the loss of humidity in the soil, protects the root system from the summer heat, from the growth of various weeds, soil erosion. In addition, a positive climate is created for the functioning of bacteria, as well as the looseness of the Earth. This procedure can be carried out manually to gardeners or with the help of a special automated, designed for this type of work, technology.

Additional procedures

When feeding the trees fertilizers, a number of additional events should also be carried out. First of all, it should be told about watering. Calculation of water consumption: up to 200 liters per plant. Roughs must be abundantly watering in the autumn period, since in winter plants need large amounts of moisture.

It should be remembered that the moisture, first of all, is needed by Tias and Fir. Sprinkle is carried out in the fall and spring to eliminate dirt on the needles. When a tree is young, you need to fight weeds, as they are carriers of diseases can absorb moisture. There should also be procedures for shallow loosenings, trimming of damaged and measurement processes and tapping in order to protect against negative weather conditions.

Unwanted nutrition for coniferous trees.

As already mentioned, the main enemy for evergreen plants is nitrogen. In this regard, it is necessary to exclude all fertilizers containing this element for coniferous.

The main one of these fertilizers is manure whose composition is overflowing with nitrogen content. Making it in the soil will provide a "burning" of the entire root system, both young and age conifers. Also, manure can lead to the formation of shoots, the growth and development of which does not always end in the winter period, as a result of which immature growths simply die due to cold weather. Manure can only be used in the form of a humor (three-year period), and it is not entered, but sprinkles on the ground around the plant. Such a procedure is carried out in spring.

And a little about the secrets of the author

Have you ever experienced unbearable joint pains? And you do not care what you know what:

  • the inability to move easily and comfortably;
  • discomfort with rages and descents on the stairs;
  • unpleasant crunch, clicks are not on your own accord;
  • pain during or after exercise;
  • inflammation in the field of joints and swelling;
  • caught and sometimes unbearable new joint pains ...

And now answer the question: does it suit you? Does such pain be tolerated? And how much money did you "merge" for ineffective treatment? Right - it's time to finish with this! Agree? That is why we decided to publish an exclusive interview with Oleg Gazmanov, in which he revealed the secrets of getting rid of pain in the joints, arthritis and arthrosis.

ATTENTION, only today!

When the cold is retreating and the next vegetative period begins, the fantastic conifer is very important, because the base is laid in the spring for the development of plants throughout the warm season.

  • What is better for coniferous plants - organic or minerals?
  • How to make feeding?
  • How to understand that conifer lacks fertilizers?
  • The most balanced fertilizer complexes
  • 1 What is better for coniferous plants - organic or minerals?

    First of all, let's understand why fertilizers need plants. Decorative deciduous exclusively for the development of foliage from the kidneys and aging new shoots, that is, for the permanent annual renewal of the crown. The fruit cultures of the feeding are also needed for spice fruits, firewood or berries, and you should not forget about all the same leaves with processes and blooming flowers at a certain period.

    That is, such trees without making balanced additives in the soil almost certainly developed if it does not stop, it will slow down. Coniferous types of foliage do not change, and therefore need to be fed to a much lesser extent. Therefore, it should be understood that it is to offer them and in what quantity. The manure in pure form is clearly not suitable for plants, and anyone, since it contains too much nitrate and nitrogen, the overdose of which is adversely affect the roots. Today, many farmers are actively used by the Korovyan, that is, the same fresh manure, but diluted with water.

    Cow duty with water

    Of course, the concentration of most substances in such a solution is strongly reduced, but still it is not the most the best way For garden crops, and even more so for coniferous plants. For the latter, biohumus is best suited, that is, an organic substrate, recycled with rainworms. In general, it is recommended to use compost as the organic, that is, the dung mass over several years. As for the mineral feeding, how it was already said, it is better to do without nitrogen-containing complexes, when it comes to conifers.

    What is harmful to them nitrogen? First of all, the fact that it encourages shoots to grow rapidly, moreover, the young needles are very dragging, but at the same time he absolutely does not have time to ripen over the growing season. As a result, young inappropriate branches after the onset of cold weather are frozen and fall, or forever remain brown, which is very spoil appearance Tree. It is better to prefer fertilizers containing magnesium. The thing is that the needle that replaces the foliage is much better adapted for photosynthesis processes, which without a large number of magnesium flows very slowly.

    2 How to make feeding right?

    As a rule, such fertilizer trees are needed only in the first years until they fix it. Due to the long life of coniferous species, 10 years after landing, they must be fed. It is usually done twice a year, in the spring and at the end of the summer (or early autumn). At the beginning of the vegetative period, only mineral fertilizers are needed, and it is allowed in minor quantities and nitrogen, for the accelerated growth of the tree during the warm season.


    Mineral fertilizers for conifers

    Also, the spring is accepted in the process of soil looser (in order to improve the flow of moisture and air in it) to add the organic, but exclusively compost. It is mixed with a fertile layer, no more than 3 centimeters thick. So that the trees are not accustomed to abundant feeding and at the same time received a complete complex of nutrients during the season, the soil fertilizer can be reduced by 2 times, and add the second half in June.

    In winter, photosynthesis in coniferous plants practically does not proceed, so they almost do not need magnesium. Consequently, in the fall, it is possible to make the same complex of minerals as in the spring, but it is recommended to make focus on potassium, which strengthens the root system. Thanks to such a supplement, trees and shrubs will be easier to suffer severe cold. At the same time, in order to stretch the assimilation of the feeding, it is possible to make a granular complex in the rolling circle of early autumn, so that, together with watering and absorbing rainwater, the necessary substances gradually entered the roots.

    External signs are clearly distinguishable, especially with acute lack of minerals. Moreover, even a shortage of nitrogen in the soil may noticeably affect the plant: in this case, very slow growth will be discovered, including the development of the barrel in the thickness, the branches will be quite rare, the needles are faded. With an extremely small amount of phosphorus, the picture is somewhat different: the development of a seedling is also slowed down, but the needle is very short, sometimes even twisted, tips can be from yellow to purple-brown color.


    Lack of nitrogen in the needle shrub

    If there is not enough potassium, the needles initially becomes a flexible, with a yellow, with brittle endings, and after 2 years it becomes a drone and dies (more notarily these processes proceed in well-lit crown sections). As already mentioned, in addition to the listed elements of coniferous plants, magnesium is needed so that photosynthesis contribute to the nutrition of trees. If in the soil there will be a lack of this mineral, the chevings will become yellow, and in a few years the color will reach the golden, because of what the trees will look dry.

    Insufficient supply of a plant with calcium will affect it no less harmful: resin will be allocated on the trunk and branches, especially at the base of the kidneys, and in time, the elite of the crown will begin to die. When little sulfur, the needles turn yellow and develop poorly, because of what is usually very short. Worst of all, if there is not enough boron, in this case the winter-hardiness of the plant, as well as drought resistance, strongly decreases, a tree or bush may not survive a hot summer or a cold winter.

    4 Most balanced fertilizer complexes

    What is a comprehensive feeding? Judging by the title is a fertilizer that contains a large number of trace elements. Ideally, there must be at least 12 to provide coniferous plants with all necessary for their livelihoods. Such can be attributed, for example, a complex Green Guy or Rockogumin complex. Some manufacturers do not care about beautiful namesAnd they write simply "Complete feeding for conifers for spring (or autumn)."

    However, you need to choose such fertilizers very carefully, they must contain a minimum of nitrogen and maximum magnesium, also desirable the presence of manganese.


    Magnesium fertilizer for coniferous plants

    In some cases, you can get by adding individual elements And even substances containing them. In particular, nitrogen and many other minerals are quite enough in the compost, but it is necessary to use it carefully, and at the first signs of exceeding the norm necessarily extend a fertilized soil layer from the rolling circle. As a rule, the signal becomes a change in the color of the needles, it acquires a yellowish or even browned hue that spring among the greenery will be especially noticeable. In exchange, you immediately put on the sand with an admixture of clay and provide trees, cobbled minerals, abundant watering.

    You can use a dolomite flour, but it should be remembered that it reduces the soil acidity, the balance can break sharply. In general, many trace elements are part of chemicals permissible for feeding. For example, nitrogen is contained in ammonia Selitra and ammonium sulcine. Moreover, the first fertilizer is recommended for Suglinka, as well as on the podzol, especially where acidity is increased, and the second is suitable for chernozem. Superphosphates, as it should be, are the source of phosphorus, and potassium salts are potassium.

    When the cold is retreating and the next vegetative period begins, the fantastic conifer is very important, because the base is laid in the spring for the development of plants throughout the warm season.

    As a rule, such fertilizer trees are needed only in the first years until they fix it. Due to the long life of coniferous species, 10 years after landing, they must be picked up.

At the beginning of the vegetative period, only mineral fertilizers are needed, and it is allowed in minor quantities and nitrogen, for the accelerated growth of the tree during the warm season.
