All about feeding apple trees in autumn

Any fruit tree needs feeding. Fertilizers improve the immunity of crops, improve the quality of the soil. For apple trees, one of the most important dressings is autumn. The features of fertilizers for this period should be known to all summer residents growing apple trees on the site.

During the spring and summer seasons, the apple tree absorbs many nutrients from the soil, therefore, by the fall, the soil often becomes depleted. It is impossible to allow a tree to go to rest on such a soil.

In addition, top dressing before winter has the following positive aspects:

• the tree survives the winter much easier;
• he has increased immunity;
• the plant begins to bear fruit more abundantly;
• the apple tree is less attacked by pests.

It is very important to choose the right time for the autumn feeding, because if the soil freezes, it will be not only impractical to add something to it, but even dangerous. It is best to do fertilization a couple of weeks after harvesting: during this period, the apple tree begins to form suction roots. This means that the feeding will be fully assimilated.

When choosing the timing of feeding, you also need to focus on the region of your residence. So, in most areas, they begin to prepare the tree for winter in the first half of September. If the gardener lives in Siberia, as well as in the Urals, then autumn feeding will have to be applied in the summer - in the second half of August. Summer residents from the southern regions can wait until October. The main thing is that at least 3-4 weeks remain before frost.

Before feeding trees, they must be carefully examined. If lichens appear on the trunks, then it is very important to clean them off with a disinfected tool. They do the same with the bark lagging behind the tree. Sections and wounds must be treated with copper sulfate. Then a garden var is applied to them.

All dressings are divided into two large groups: organic and mineral. It is worthwhile to familiarize yourself with these categories in more detail.

You can fertilize apple trees for good wintering with the following mineral compositions.

• Phosphoric. This includes superphosphate and its double variety. If the trees lack this particular element, then yellow spots with a green tint will appear on the leaf plates. Such foliage will quickly wither and fall off. Phosphorus must be dosed. Enough 30 grams per square meter.
• Potash. You can determine that apple trees need potassium by their fruits. If it is not enough, they quickly begin to shrink. For such dressings, you can use potassium sulfate or potassium magnesium, which is even more useful. In both cases, take 30 grams per square meter.

There are a few other useful tips worth considering.

• Sometimes apple trees lack boron. This is a very important element for them. Lack of boron causes foliage to thicken, darken and subsequently fall off.To improve the situation, you need to stir 10 grams of boric acid in a bucket of liquid, and then spray the apple trees.
• In order to have a good harvest next year, trees can be fed with nitrophos or nitroammophos. The first drug is taken in an amount of 50 grams, the second - 200. The agent is not dissolved, they just need to sprinkle the earth, and then dig it up.
• Phosphorus and potassium must be added correctly. Around the perimeter of the trunk circle, you need to dig about 6 holes, and then put fertilizers in them. Then the top dressing should be mixed with the substrate and the latter should be abundantly irrigated. The holes are dug in, a layer of turf is laid out on top. In addition, foliar feeding can be done with phosphorus. Take 0.1 kg of superphosphate, dissolve in 10 liters of water, then spray the crown.
• Autumn fertilizers can be combined with preventive crop treatments. Usually trees are treated with Bordeaux liquid. Its concentration should be 3%.

Organic matter saturates the soil, restores its useful qualities. However, it should be borne in mind that organic matter decomposes for a long time. The decay period of such fertilizers is about 5 years, so it is a big mistake to apply them annually. At a high concentration in the soil, organic matter will begin to become moldy, due to which apple trees can get sick with a fungus. It is worth updating such dressings every 4 years, not more often.

In the fall, you can add rotten manure, compost and humus compositions. But fresh manure, chicken and mullein are not given in any case. The fact is that such dressings contain a lot of nitrogen, and the apple tree does not need it in the fall. On the contrary, it will be harmful. If there is a large amount of nitrogen in the soil in the coming season, the apple tree will acquire abundant delicious foliage, but it may not give any fruit at all.

When applying organic fertilizing, you need to take into account the age of apple crops. If the tree is less than 7 years old, 2 kilograms of the selected product per square meter will be enough for it. Plants that are 7 to 12 years old are already given 4 kg. After 12 and up to 20 years, the dose is increased to 6 kilograms. If the tree is even older, it will need at least 8 kg of organic matter.

What else can you do:

• mulch the near-trunk circle with peat;
• add 300 grams of wood ash (if potassium is needed).

Also, some gardeners can use certain folk remedies to increase yields. For example, the soil can be sprinkled with bone meal or shed with a yeast-based dressing.

There are two ways to apply dressings in the fall. Let's consider both.

This method involves the introduction of fertilizers directly into the trunk circle, but not clearly under the root, but along the perimeter. Before applying, the soil is spilled abundantly, because otherwise the fertilizer may burn the roots of the apple trees. Root dressing can be applied in two ways.

• It is necessary to spread fertilizers around the perimeter of the trunk circle, and then dig up the soil so that the fertilizing mixes with it. Then the substrate is watered again and peat mulch is placed on it.
• In the second case, grooves are dug 0.2 m deep, fertilizers are poured there. Top dressing should be mixed with soil. Dig in, irrigate abundantly. It is important to take into account that the dug furrows should be at a distance of 0.6 m from the tree itself.

This method is relevant, but it is extremely rare in the fall. The fact is that the method gives a quick result, but it will not last too long. Foliar dressing is nothing more than spraying. The selected fertilizer is diluted in water in accordance with the instructions, and then applied to the crown, branches and the soil itself under the tree. Thus, it is possible to quickly make up for the lack of any substance or heal the plant.

Even inexperienced gardeners know that any fertilizing must be applied correctly. After all, if you make the wrong dose, then they will not help the plants, but only harm. However, it is necessary to take into account not only dosages, but also other features.

It is very important to take into account the variety of apple trees, since some varieties require a certain approach to themselves. For example, dwarf varieties. Due to their small growth, they naturally require less fertilizer than a large tall apple tree. If you want to apply autumn top dressing to the soil, then reduce the amount of fertilizer by about 30%.

You should also be careful with columnar varieties. Their roots lie very close to the surface. Therefore, deep digging is strictly prohibited here. Fertilizers need to be scattered on the surface, and then only slightly dug up the substrate. Do not forget to irrigate the ground with plenty of water.

When a planting hole is being prepared for an apple tree, fertilizers are always applied to it. Top dressing made during planting lasts for 2-3 years for the trees. They are not fertilized at all during this period.... The introduction of nutrients in the fall begins from the fourth season, after the harvest.

But the age of the culture must also be taken into account. A young apple tree needs less fertilizer than an adult one. Young trees are considered when they are 4-8 years old. For such apple trees, the standard dose of fertilizers should be divided by 2. Moreover, it is best to use not dry granules with digging, but liquid mixtures.

Young trees take organic matter well. If you decide to add a dry composition, then take into account the size of the trunk circle. In a young apple tree, it is small, so fertilizers are placed further away so that they do not come into contact with the roots.

As for old and adult apple trees, their dosage can be increased up to two times, especially if the lack of any element is clearly visible.
