Features of feeding apple trees in summer

The key to an excellent harvest is top dressing, which is carried out in compliance with the frequency and application rates. Apple trees simply need a large amount of minerals, especially during the laying of flower buds. What and how to properly feed the trees in the summer, we'll talk in this article.

plant needs

The apple tree is a rather tender plant, especially at a young age. Feeding without special need will only bring harm. In general, if there is not enough nutrition for apple trees, it is noticeable even to the naked eye. If the trees do not have enough nitrogen, the foliage becomes small, faded. When there is little phosphorus, the leaves become bronze in color, and a clear lack of iron is characterized by yellowness of the leaves, a complete loss of color.

When trees lack calcium, the leaves will curl and fall, and a lack of copper causes dark spots on the leaves. Foliar top dressing will correct the situation and saturate the trees with the necessary and useful substances. But maximum success can be achieved if the application methods are alternated and root dressings are also used.

Now a little more about the lack of other substances. So, the signs of magnesium deficiency:

  • the leaves become crimson or lemon in color, while the edges and veins are green;
  • young leaves look like a mosaic.

In the case of a lack of boron:

  • leaves begin to die off from the edges;
  • few ovaries, flowering is also weak;
  • the fruits take on an ugly shape;
  • inside the apple there are corked areas;
  • the top of the branches dries up.

These are clear signs that the tree is experiencing "boric hunger". It is especially common in acidic soil.

If the trees are low on potassium:

  • foliage is bent down;
  • all branches are thin, weak;
  • There are many flowers on the apple tree, and the fruits are hard and bitter.

By and large, apple trees need both mineral and organic fertilizers. As organics are used:

  • compost;
  • mullein;
  • chicken manure;
  • horse dung.

If we talk separately about mineral fertilizers, then the biggest need for apple trees of various varieties is phosphorus, nitrogen and potassium.

From the category of phosphoric, gardeners are of great interest in superphosphate + phosphorus flour, and from the category of nitrogen - urea. The most common source of potassium is potassium salt, potassium sulfate.

Universal vitamin cocktails, which are widely represented in retail chains in different cities, are also successfully used. They immediately contain a complex of micro and macro elements.

This type can include:

  • ammophos - combines phosphorus and nitrogen compounds;
  • nitrophoska - contains a huge amount of substances, such as nitrogen, potassium, copper, boron;
  • nitrophos - perfectly absorbed, contains compounds of nitrogen and phosphorus.

In the second half of the summer period, only substances of the phosphorus-potassium type are needed. They are necessary for the growth and proper development of future bulk and tasty apples.

And now let's go directly to the methods and options for fertilizing. Let us also turn to folk recipes, which, by the way, are relevant for many gardeners, as they have a milder effect.

What can you feed a tree?

Summer top dressing of apple trees brings great benefits, so it should not be underestimated. The main difference between such dressings and spring ones is that it is allowed to apply not only nitrogen-type fertilizers, but also potassium salt, as well as phosphorus fertilizers.

If the summer turned out to be quite hot, then top dressing can be made several times. The main condition is to observe the interval between fertilization, which is 10-14 days.

So, let's start with folk recipes. The first is top dressing using ash. This tool will allow the apple tree to effectively bear fruit.

We take 1 cup of wood ash and dilute it in two liters of hot water. We mix it all, wait until the ash is completely dissolved. After that, we increase the volume of the mixture to 10 liters and carefully spray the crown. Such top dressing can be carried out during the entire period when apples ripen. Do not forget only about the ten-day interval between applications. Completely stop fertilizing 30 days before picking apples.

You can use the following recipe: we take 1 kg of superphosphate, 800 g of potassium sulfate, 500 g of urea and dissolve all this in a 200-liter barrel of water. Let this mixture sit for about a week. The average consumption of the mixture is 4 buckets for watering one tree. In order not to burn the entire root system of apple trees, pre-irrigate with clean water. But in the rain, such top dressing is not carried out, the weather should be dry.

You need to understand that when choosing fertilizers, you should take into account the composition of the soil and the age of the apple trees in your garden. In the southern regions, where there is initially a lot of organic matter in the soil, one should not overdo it with the introduction of compost and humus.If you live in the northern region, then you should not use fertilizers containing chlorine, this will harm both the soil and the apple trees.

The next fertilizer option is a solution of bird droppings or mullein. To properly prepare it, take a large container (the most suitable is a 200-liter barrel) and fill it with water. Then dissolve 5 liters of bird droppings in water. On average, this volume is enough to feed 5-6 apple trees.

Feed the trees in the evening or early in the morning so that the nutrients do not evaporate ahead of time. Feeding is carried out as follows:

  • the trunk circle of an apple tree is shed with a bucket of water;
  • then the tree is watered with the prepared solution at a distance of 0.5 meters from the trunk;
  • re-spill the near-stem circle with water.

At the very beginning of summer, apple trees need minerals. Therefore, in June, fertilizers should be applied, which contain potassium and phosphorus. You can use the following recipe: dilute 1 tablespoon of potassium sulfate in a ten-liter bucket of water. The crown of the trees is sprayed with this solution, so that the foliage on both sides is processed.

Also great for top dressing and the well-known boric acid. The recipe is simple: add 2-3 mg of boric acid crystals to a ten-liter bucket and mix well.

On average, after 2 weeks you can feed the apple trees with nitrogen. For this, urea is quite suitable. The solution can be used in two versions:

  • if the summer is hot and there is a drought, it is better to spray the crown with a solution;
  • if the weather is rainy, then root dressing will give a greater effect, in this case, the near-trunk circle is simply shed with fertilizer.

In order not to harm the apple trees while feeding with urea, you can conduct a kind of test.One branch is sprayed with the prepared solution and left for several days. If the foliage is the same color and does not fall off, you can safely spray the trees. If the color of the foliage becomes different, you need to reduce the concentration of fertilizer.

Feeding in July will also bring significant benefits. During this period, we use potash and phosphate fertilizers. If it's hot outside, spray the crown with a vitamin composition. It is also possible to introduce mixtures with a nitrogen content, only observing the interval, which was already mentioned earlier.

During fruiting, trees can be fed with sodium mixtures. During the ripening period of apples, this is very important. Carries it out according to the following recipe: take 1 kilogram of nitrophoska, 1 tbsp. a spoonful of sodium humate. Dissolve all this in a 200-liter barrel of water. In the evening, pour the near-stem circles of apple trees with the resulting solution.

A good result is given by top dressing with the so-called "green" fertilizer, that is, an infusion of various herbs.

In August, apple trees can be fed with both organic and mineral-type fertilizers. During this period, organics are laid around the trunk:

  • if the trees are young, then stepping back from the trunk by 40 cm;
  • if the apple trees are old (over 15 years old), then 1 meter from the trunk.

A bucket of organic matter is applied to one young tree, two buckets should be used for older trees. It will be great if you put fertilizer under the mulching materials.

As for nitrogen fertilizers, it is generally better not to use them in August. This is due to the fact that the branches can begin to grow actively, by the first frost they will be weak and simply freeze out.

Be sure to make sure that in the summer the soil under the apple trees is a little wet, but overflow is not allowed. Moisture is needed so that minerals dissolve well, since it is difficult for apple trees to take moisture from a great depth.

For lovers of organic gardening, the use of various green manure as a fertilizer will be very relevant. It looks like this: the soil is dug up, in the process, freshly mowed green manure is embedded in it. This allows apple trees to get nitrogen and other nutrients.

It is worth mentioning one more substance for top dressing. This is bone meal. It contains a lot of calcium, phosphorus and a small dose of nitrogen. Bone meal is usually applied as soon as the crop is harvested.

This substance decays for a long time, 6-8 months. It turns out that if you make it after picking apples, by the spring period the necessary elements will completely enter the soil.

Bone meal should be applied once every three years. At the same time, the near-stem circle of the tree is dug up and 200 g of bone meal is applied to one apple tree.

You can also use fishmeal, it perfectly restores the damaged root system of apple trees, but we must not forget that it deoxidizes the soil.

Terms and rules of fertilization

If we talk specifically about the timing in which fertilizers should be applied, then the schedule looks like this: if you planted young apple trees, then in the first year they, in principle, do not need to be fed. But in the second year after planting, you need to start fertilizing.

The first time you need to feed the trees in your garden is in mid or late April. It is during this period that the first green foliage usually appears on apple trees.

Re-fertilize at the very beginning of flowering. The third time the trees are fed on the 15th of June. Trees are maximally saturated with potassium and nitrogen. Most often, the foliar method is used, but in the heat it is permissible to use watering.

At the end of August, apple trees are fed for the last time. Fertilizers at this time saturate the trees with minerals and significantly improve the quality of the soil.

As for the rules for entering, they are simple. If it is hot outside, then it is better to water the trees in the evening so that the moisture does not evaporate too quickly. There is also a kind of fertilizer application scheme that you should pay attention to:

  • before fertilizing, the soil is watered with clean water;
  • fertilizer solution is distributed over already moistened soil;
  • water again with clean water.

Foliar top dressing produce a thicket as an emergency measure. It is usually used if apple trees bear fruit very abundantly. Keep in mind that it is strictly forbidden to spray apple trees with fertilizer if less than 3 weeks are left before fruit picking.

Those who grow columnar apple trees should be aware that these trees need vitamins and minerals somewhat more than others, since these varieties produce many fruits that require nutrition on a small number of branches.

There are gardeners who fertilize after harvest. The effectiveness of this top dressing is still a big question, but many agree that it will definitely not bring harm.

Now consider the necessary dosages that should be observed during feeding.

Dosage

Zinc

Zinc sulfate

10 g/10 l water

Nitrogen

5g/10 l water

Phosphorus

Copper

Vitriol copper

Approx. 5 g/10 l of water

Fertilizers should be applied taking into account the age of the trees, soil type, weather conditions.For example, if the soil contains a large amount of clay, then it is better to apply minerals under the root using irrigation. On such soil, top dressing can be applied only once.

If the soil in your garden is closer to chernozem, then it is better to spray apple trees with solutions of trace elements, and water them with organic matter only if there are signs of a fungal disease.

If the trees are less than three years old, then you can feed them with dry fertilizers. The granules are placed near the trunk circles, and then, with the help of a rake, they are shallowly instilled.

When the root system is fully formed, fertilizers must be applied to a depth of 30-40 cm. For this purpose, small grooves are made, fertilizers are laid in them.

Wells of appropriate depth can also be used. A hollow pipe is inserted into each well, and a vitamin solution is poured into it. For 1 sq. meter of soil on average need 2 wells.

Tips from experienced gardeners

Beginning gardeners most often make several common mistakes:

  • do not observe the interval between fertilization;
  • carry out top dressing more often 5 times a year;
  • the first time they feed the apple tree after flowering, and not before it begins.

To avoid problems with yields or “overfeeding” with fertilizers, it is necessary to strictly observe the terms and dosages of application.

Also, inexperienced gardeners should be aware that 30 days before picking apples, any top dressing must be stopped.

Timely introduced "vitamin cocktails" for apple trees will provide a large harvest of strong and healthy fruits. It is necessary to fight not only with pests and diseases, but also to replenish the gradually depleted supply of nutrients in the soil. But with what to fertilize your favorite seedlings, everyone chooses for themselves, fortunately, the choice is now really huge.
