How to feed an apple tree during and after flowering?
Every year, apple trees in summer cottages delight their caring gardeners with a tasty and nutritious harvest. With proper care, you can provide yourself with apple blanks for the whole winter. The quantity and quality of apples depends on the right variety, weather conditions, the place where the tree is planted and proper care for it. The last factor involves timely pruning, watering and applying various fertilizers to the soil.
Why do we need top dressing and what are they?
You need to feed the apple tree systematically.
By introducing top dressing into the land on which the culture grows, a person achieves the following goals:
- improves soil quality;
- promotes the formation of ovaries;
- maintains a high yield of apples;
- helps to improve the quality of fruits;
- enhances culture immunity.
A gardener interested in the harvest feeds his offspring 4 times, and each such feeding has its own mission and purpose.
- The first fertilization is carried out in the spring from the third week of March to the third week of April. During this period, leaves form on the tree. The tree is awakening from its winter sleep, and it needs nutrients to return to its working form. At this time, it is important not to oversaturate the soil with nitrogen, which is more for the growth of branches, and not for the formation of ovaries. In cold regions, this top dressing is performed in May.
- The second feeding takes place in June.Here, more than ever, the apple tree needs potassium, phosphorus, as well as trace elements necessary for the formation of flower buds.
- From August to September, the first autumn dressing awaits the tree. Not all gardeners fertilize the soil under the apple tree in August. But timely top dressing is certainly needed at this time, so that the tree has time to take all the nutrients before the onset of cold weather.
- The last fertilization is carried out from September to October. Again, in the autumn, many do not pay attention to their wards, but experienced gardeners still recommend feeding apple trees in the fall. Fertilizers will help the trees to better endure frosts, and by spring they will still have a supply of necessary substances that apple trees will need.
There are 2 types of fertilizer application.
- Root fertilization occurs after watering the apple tree. Having saturated the tree with water in the amount of 15 liters for a five-year-old tree and 30 liters for a ten-year-old tree, fertilizers are distributed near the tree trunk and then the soil is mulched with peat.
- The foliar method of fertilizing differs from the first one in that mineral substances are applied directly to the leaves of the apple tree using a sprayer. Thus, they quickly penetrate the plant and enrich it. But this type of fertilizer must be carried out a month before harvest.
Spraying apple trees is most often used as an additional top dressing, as well as protection against many diseases and parasites. It is necessary that the liquid gets not only on the crown, but also on the skeletal branches. Spraying is performed 3 times - before the appearance of flowers, during flowering, and then a month after it. And also use solutions with manganese, zinc, potassium and boron.If you buy a means for feeding apple trees in specialized stores, then you need to carefully study the composition (it should not contain chlorine compounds).
Ash, which contains potassium and phosphorus, is also used for foliar feeding of fruit crops. First, a glass of ash is diluted in 2 liters of non-hot water, and then this mother liquor is mixed in a ten-liter bucket of water. Apple trees are sprayed with organic matter. To do this, mix 500 g of slurry and 1 bucket of water. Often a teaspoon of urea is added to this solution and the tree is sprayed with this solution in the spring.
Types of fertilizers
At different times, apple trees need different substances. During the flowering period, they need phosphorus and nitrogen. Closer to the appearance of the ovaries, potassium will be needed. And a young seedling 2–3 years old does not need fertilizers. The apple tree is not picky about the compositions. She will appreciate both organic top dressing, and she will also like the mineral one.
You can choose any option, for example:
- ammonium nitrate;
- urea;
- manure;
- nitroammophoska.
Important! You have to be careful when using nitrogen. Incorrect dosage can lead to damage to the tree. Subsequently, this can be deprived not only of the fruit, but of the whole tree.
All fertilizers by composition are divided into organic and mineral. If you fertilize apple trees exclusively with organic matter, then the choice is quite wide. Such top dressing is useful during the formation of ovaries.
Most experienced gardeners choose from several top dressing options.
- Bird droppings contain nitrogen. It is used dry along with sand to protect the root system of the tree. It is laid 40 cm deep into the ground in a circle at a distance of 50 cm from the tree trunk.
- Mullein. Mullein feeding is rich in humus, which fills the roots of the tree with the most necessary.The best result for the apple tree gives a liquid version of this fertilizer. But it is not suitable for young growth, as it can ruin young roots.
- Horse dung applied to the soil in liquid form in the autumn.
- Compost is rich in potassium and phosphorus. It has a large concentration of various kinds of vegetation (leaves, grass, weeds, etc.) and vegetable debris.
Mineral fertilizers as top dressing also bring many benefits to apple trees. True, they have both supporters and opponents. Some gardeners believe that mineral dressings are unsafe for both apple trees and humans. This fact cannot be refuted. Since, without observing the dosages, it is possible, indeed, to cause irreparable harm to the culture. But if you follow all the instructions, then the negative consequences can be minimized.
You can determine which mineral is missing in a tree by the following signs:
- small leaves with weak pigment indicates a lack of nitrogen;
- reddish spots on dull leaves indicate a phosphorus deficiency;
- the edges of the leaves twisted down and the bluish-green color will indicate that the tree lacks potassium compounds.
It is worth considering the properties of each mineral in more detail.
- Nitrogen has a positive effect on the growth of new branches and strengthens the roots of the tree, but it cannot be used to feed seedlings, as it can burn the entire root system of a young apple tree. Nitrogen-containing fertilizers are ammonium sulfate, ammonium nitrate, urea.
- You can increase the yield by applying fertilizers based on phosphorus. These include phosphorus flour and superphosphate.
- Potassium compounds in top dressing form the resistance of fruit-bearing trees to various diseases.Immunity is increased by such top dressing as potassium salt and potassium sulphate.
There are also complex balanced fertilizers, which contain several mineral products at once.
- Nitrophos is a complex of mineral compounds, which includes phosphorus and nitrogen. It is used as the main fertilizer in the autumn and spring periods.
- Nitrophoska - This is a fertilizer that, in addition to nitrogen, potassium and phosphorus, contains iron, boron and magnesium. It is used in spring and autumn as the main food, and in summer as a top dressing.
- crystallin is a composite of nitrogen, potassium and phosphorus compounds. It is used as top dressing, which instantly penetrates the soil (only for top dressing of apple trees in spring).
- Ammophos - This is a top dressing, which consists of a large number of phosphorus compounds. Ammophos feed the crop as the main food in spring and autumn.
- Nitroammophoska is a mineral fertilizer that improves the quality of the soil in autumn or is used as the main nutrition in liquid form in the spring. In autumn, fertilizer is used to feed trees.
Important! Nitrogen fertilizers are used in the spring to increase the number of new shoots. And they also stimulate the flowering process well. And from the middle of summer, the tree needs potash fertilizers for the ripening of buds and the formation of fruits.
Peat compost is another complex fertilizer that combines both mineral and organic components.
It is prepared according to the following scheme:
- in a box with garden soil, a layer of peat up to 50 cm thick is laid out and covered with a ten-centimeter layer of waste vegetables and vegetation without seeds;
- having compacted the top layer, this “pie” is left to compost for 1–2 years;
- peat in combination with nitrogen-phosphorus compounds enriches and restores the soil thanks to useful substances.
Ash is also used as fertilizer for the soil under fruit trees. It reduces the acidity of the soil and enriches it with potassium and calcium. This fertilizer is safe due to the absence of harmful nitrates, which are found in some mineral fertilizers, as they can accumulate in the soil and then in the fruits. To prepare such top dressing, you will need ash (2 kg) and a bucket of water. After mixing, you need to infuse the solution for about 24 hours, then irrigate in dry weather at the rate of 2 liters per 1 tree. The ideal period for applying such fertilizers is spring. With the help of such nutrition, you can increase the yield, improve the quality and taste of apples.
Schedule
To improve fruiting, strengthen the roots and the general immunity of the tree, fertilizers must be introduced according to a schedule that shows what time of the year it is necessary to feed, with what fertilizer, in what volume. For different regions, the timing of applying fertilizers to the soil is different. For example, in the autumn in the Moscow region, apple trees are fertilized later than in the Urals or Siberia. In this regard, it is necessary to take into account all factors, including weather, which undoubtedly affect the processes of assimilation of nutrients by apple trees obtained by feeding.
Fertilizers are applied according to the following schedule:
- the first top dressing - before opening the kidneys;
- the second top dressing - with an increase in the ovaries up to 2 cm in diameter;
- the third dressing - a month after the appearance of flowers;
- the fourth dressing - after picking apples.
Landing
When planting a seedling, you will need components such as:
- 1 kg of ash per 1 seedling;
- 1 bucket of humus per 10 liters;
- 3 buckets of 5 liters of compost;
- 3 buckets of peat.
All ingredients are mixed and laid out in the holes in which the seedlings are seated. Under no circumstances should seedlings be fed with mineral fertilizer.
This top dressing is allowed only in the 2nd or 3rd year of the tree's life.
Before, during and after flowering
After the snow has melted, the apple tree fertilize with the help of sprayers with the following compositions:
- for one-year-old trees, ammonium nitrate is used 20 g per 10 liters of water;
- for an adult apple tree - ammonium nitrate 40 g per 10 liters of water;
- potassium sulfate 5 g per 5 liters of water (for a tree of any age).
Peat, bird droppings, and manure are the best options for top dressing for a fruit-bearing tree in the spring. Raw materials in proportions of 1: 3 must be mixed with water and then infused for 2 weeks, shaking occasionally. The present solution will need to be diluted with a bucket of water and feed the apple tree. Mineral fertilizers help the gardener cope with many fungal diseases of trees. So, for the prevention of fungus in the spring, as well as before the appearance of flowers, 3% ammonium nitrate is used in a volume of 30 g per bucket of water. During the growing season, ammonium sulfate 3% in a volume of 20 g per bucket of water can help with this ailment.
During the flowering period, root dressing is usually used. They are fed most often with complex mineral compounds.
To do this, take the following ingredients:
- 400 g of potassium sulfate;
- 500 g of superphosphate;
- 250 g of urea;
- 100 liters of water.
This mixture is infused for about a week. When using it for 1 apple tree, 4 buckets of the mixture are needed. And also, if possible, 5 kg of mullein or 2.5 kg of bird droppings are added here.
And also often use the following compositions:
- 1 liter of water and 1 g of superphosphate;
- 1 liter of water and 6 g of potassium sulfate;
- 1 liter of water and 50 g of urea;
- 1 bucket of water and 5 kg of mullein;
- 1 bucket of water and 2 kg of chicken manure.
Urea as a fertilizer is used both in irrigation and for spraying. Mix 20 g of dry urea with 10 liters of water, then spray the branches with this solution. For this method of feeding, the agrochemical "Kemira" 20 g per 1 bucket of water is also used.
Important! Before top dressing, water the near-stem circle abundantly.
During fruit ripening
For feeding the fruit tree after flowering use the following compositions:
- 1 g of sodium humate and 50 g of nitrophoska per 10 liters of water at the rate of 3 buckets of the mixture per 1 apple tree;
- top dressing from the infusion of grass on the water in proportions of 1: 10; it is insisted for 20 days and used 20 liters of infusion under 1 tree.
If you use foliar top dressing, then the following products are best suited for spraying:
- urea 50g per bucket of water;
- infused with warm water for at least a day, ash 200g per bucket of water.
Such top dressing is carried out in the morning or evening hours, when the sun is still low, so the risk of leaf burn is minimal. It is possible to process with this solution not only the crown, but also branches with a tree trunk. Before the procedure, it is necessary to check the concentration of the solution on 1 branch.
If after a day some changes appeared on the leaves, then the concentration is high, the solution must be diluted to reduce it.
autumn
Top dressing of apple trees in autumn is carried out in late August or early September. In autumn, nitrogen fertilizers are not applied, which provoke the growth of new branches. Phosphorus and potassium are minerals that are essential for wood before the winter cold. If there are leaves on the tree, foliar top dressing is carried out by spraying them with a solution of superphosphate at the rate of 150 g per bucket of water.If the root method is used, then fertilizers, more often manure, are scattered on the near-stem circle and the soil is dug up to a depth of 20 cm. It is recommended to use only stale manure and in no case fresh. Two buckets of manure is enough for 1 apple tree. After digging, you should water the soil so that the nutrients get to the root system of the tree faster.
In early October, additional top dressing is introduced, for example, a solution of slurry. To prepare it, the barrel is filled with manure by one third and filled with water, stirring occasionally for 3 days. Having diluted the slurry in proportions of 1: 5 with water, the soil under the tree is watered with this solution.
The following means are also used to feed trees in the fall:
- ash;
- phosphorus flour;
- potassium sulfate;
- bone flour.
Bone meal contains calcium, which gives the fruits their flavor. It begins its work after 8 months, so it is necessary to introduce bone meal after picking apples, and just in time for spring, calcium will begin to work on shaping the taste of future apples. Bone meal is used once every three years. Infrequently, but you can also find the use of fishmeal as a nutritious raw material. This flour works on the damaged root system and deacidifies the soil. It also has a lot of phosphorus, potassium and nitrogen. Ash enriches the soil with potassium, but it cannot be applied along with nitrogen and compost, since it neutralizes their effect.
Important! To protect the roots from frost, the soil is mulched with needles, nutshells and straw.
Fertilizer specifics
When feeding an apple tree, it is necessary to understand that the feeding of a young and adult plant is different. The roots of young trees can be easily injured by the wrong dosage of the drugs used in top dressing.Improper use of it leads to damage and further death of the plant.
For seedlings and young trees
The fertilizer that is put into the planting hole can be enough for 3 years, since the apple tree finds its own food in different layers of the earth. However, this only works on fertile soils. If the soil is watered, top dressing will have to be introduced every year. The first fertilizers for young trees are introduced 2 years after planting. Before this, it is necessary to water the soil well, put fertilizer on the near-stem circle at a distance of 25 cm and loosen the soil. In no case should you scatter top dressing near the tree trunk - you can simply burn the roots of the seedling.
Mineral fertilizers are contraindicated for young apple trees, they begin to be introduced later.
For adult plants
After 3 years, when the root system has formed, top dressing begins to be buried in the near-stem circle to a depth of 40 cm. To do this, they dig circular grooves near the tree trunk or arrange for 1 square. m, 2 or 3 wells up to 40 cm deep, which are filled with a nutrient solution. Mature trees are fertilized with both organic and mineral raw materials. A combination of these two options gives the best result. If you add peat and phosphorus to manure, then such top dressing will bear fruit. If a mixture of superphosphate with manure is used as a fertilizer, then the yield will be higher than after feeding with the same fertilizers separately. Therefore, for mature trees, composite fertilizers from organic matter and minerals are the best top dressing, since thanks to it the yield increases several times.
gardening tips
To solve problems in time, You need to keep a close eye on changes such as:
- if the leaves turn pale or turn yellow, this is due to a lack of nitrogen;
- dark brown stripes indicate a lack of potassium;
- darkening of the leaves signals a deficiency of phosphorus;
- iron deficiency can lead to chlorosis;
- folding leaves into rosettes indicates a lack of zinc;
- yellow leaves with red veins are an indicator of a lack of boron.
Any visible changes can lead to a decrease in yield, the number of apples decreases, they become small and tasteless. If there was no time for root dressing in the spring, you should try to carry it out in the summer with a sprayer to instantly nourish the tree with useful minerals. This option of fertilizing is assimilated within 2-3 days.
In order not to ruin your trees, and every year to get an excellent harvest of apples, you must follow the following rules:
- the first dressing is done before the flowering of the tree;
- during the growing season, it is quite enough to fertilize the soil 3 or 4 times or by the foliar method;
- between top dressing there should be a period of at least 10-14 days;
- root dressing is applied only to the near-trunk circle at a distance of 60 cm from the trunk of an adult tree, so as not to burn the roots of the apple tree; the outer diameter should be no more than the projection of the crown on the ground;
- a month before harvesting, all manipulations for fertilizing both the root and foliar methods are completed;
- always consider the age of the tree before deciding to fertilize;
- the high efficiency of the fertilizer is determined by its correct application to the near-stem circle.
There are many options for increasing the yield of apple trees, but fertilization is one of the most effective.If the gardener wants his apple tree to bear fruit every year, it is in his hands to choose the right feeding schedule and choose all the ingredients for the full nutrition of the plant. The result of such care will be a beautiful fruit-bearing tree that will delight you with delicious apples and a beautiful color.
