It is unlikely that there is at least one household plot on which this unpretentious and unusually productive tree would not grow. Due to their ease of care, apple trees grow in almost any region of Russia. But not every gardener pays due attention to them in the fall. Most are limited to harvesting and gardening. Few people know that, in addition to the obligatory annual work, it is necessary to help the trees accumulate nutrients and prepare for winter. And feeding the apple trees in the fall will help in this.
Why fertilize an apple tree in autumn
If you want to get bountiful harvests in the coming years, help the fruit trees to recuperate. Contrary to popular belief, they need to be fed not only in spring and summer. Fall fertilization is equally important. Fertilizing apple trees in autumn has its advantages:
- Restoring the balance of nutrients after abundant fruiting;
- Preparing apple trees for winter;
- Strengthening the root system;
- Increased frost resistance;
- Increased resistance of fruit trees.
The most important is the autumn feeding of apple trees in the northern regions with long winters and severe frosts.
When to fertilize
It is very important to feed the fruit trees on time. You need to fertilize apple trees immediately after carrying out standard work in the garden - pruning and whitewashing. It is advisable to combine this process with pre-winter watering. In this case, all applied fertilizers will be absorbed to the maximum extent.
You need to finish feeding until mid-late September, depending on the region of growth. Consider a very important point when determining the timing: for the complete dissolution of fertilizers and their assimilation, apple trees will need at least 3-4 weeks. Water the trees abundantly throughout this period. If autumn is generous with precipitation, in this case watering the apple trees is not required.
Preparing trees
Before fertilizing under the apple trees, you need to put things in order in the garden. Collect all debris and leaves after harvest. It is advisable to remove it from the site and burn it in order to prevent the spread of diseases, as well as to destroy numerous insects and their offspring.
After the autumn pruning of trees, do not forget to process the saw cut with garden pitch.
Make mandatory spraying of apple trees in the fall to eliminate pests and prevent disease.
In the autumn, after harvesting, you can use more concentrated and powerful solutions for processing without fear of harming the trees.
If you do not want to use chemistry-based means for the prevention and control of pests and diseases, you can use solutions prepared yourself. Folk remedies will help you with this. Various infusions and decoctions protect trees no worse than chemical compounds bought in a store.
Only after that you can start the autumn feeding, taking into account the climatic features of your region.After the measures taken, at least 3-4 weeks should pass before frost hits and snow falls. The colder the soil, the slower the apple root system absorbs mineral fertilizers.
How to fertilize
When choosing fertilizers, you need to focus not only on the seasonality of work. An important role is played by the age of apple trees, their variety and, of course, the chemical composition of the soil. How to feed an apple tree in autumn? How to calculate the correct dosage depending on the variety and age of the trees? In what weather should these events be held? You will find answers to these and many other questions in this article.
In the fall, apple trees need to be fertilized with fertilizers based on phosphorus and potassium. From nitrogen fertilizers in the autumn period must be abandoned, so as not to provoke the formation and growth of young shoots. They will not survive the winter and are guaranteed to freeze. And their appearance and active growth will significantly weaken your apple trees before the onset of frost and they will most likely freeze out.
How to fertilize apple trees, depending on the composition of the soil
Before you deposit autumn fertilization under apple trees, you need to pay attention to the level of acidity of the soil in your area. Increased indicators of acidity or alkalinity of the soil, even with careful and timely care, immediately affect fruiting. Outwardly healthy and abundantly flowering apple tree bears very poorly.
If the acidity level exceeds the norm, then the soil needs to be deacidified. To do this, add to the root zone and along the perimeter of the crown:
- A piece of chalk;
- Slaked lime (fluff);
- Wood ash;
- Dolomite flour.
Of all the above fertilizers, gardeners deservedly consider wood ash to be an ideal top dressing. It not only perfectly normalizes the acid balance, but also enriches the soil with potassium and phosphorus.
Any of the elements you have chosen must be scattered around the apple tree and carefully dig up the top layer of soil with a pitchfork. You should not go too deep when digging, so as not to damage the roots of the tree.
With increased alkaline values, the composition of the soil can be normalized with sawdust or peat.
Mineral fertilizers: dosage and application rules
In the fall, when the growing season comes to an end, apple trees most of all need potassium-phosphorus fertilizing. Fertilizing is best done in dry weather.
Make shallow grooves around the perimeter of the crown. Pour the necessary amount of fertilizer into them and carefully level the ground. Water the apple trees liberally. In the absence of precipitation, do not forget to water the trees at least 2-3 times a week so that the fertilizers applied are completely dissolved.
For one apple tree you will need:
- Potash fertilizers - 15-20 grams per m²;
- Phosphate fertilizers - 40-50 grams per m² of the trunk circle.
Consider the age of your trees when fertilizing. An overdose is just as dangerous as a lack of nutrients.
Organic fertilizers: how much and how to apply correctly
At all times, humus, humus and manure are rightfully considered the best fertilizers of organic origin. Gardeners advise to introduce organic matter not only near the trunk circle, but also on the entire area occupied by the roots. You can determine the area of soil that needs to be fertilized in the summer. At noon, the shadow from the crown of the apple tree outlines the approximate area of root growth.
There are two methods for feeding apple trees in the fall:
- Foliar;
- Root.
Organic fertilizers can be fed to young apple trees in the fall when planting. In this case, the root system will not suffer, and the seedlings will take over much faster and have time to gain strength and nutrients before the onset of winter.
Mix well rotted organic matter in a 1: 1 ratio. Place some of this mixture on the bottom of the planting pit. Dig in the seedling with the rest of the soil and water it abundantly.
Foliar dressing
In the first case, fertilizer, diluted in the prescribed amount of water, is applied to the apple tree trunk by spraying. Before fertilizing apple trees in this way, it is advisable to clear the trunks of cracked bark, growths, lichens, moss. All damaged areas must be treated with garden varnish immediately after cleaning.
For foliar feeding, you can use a 5% solution of copper sulfate. Prepared solution spray the bark of the apple tree... In this case, the trees will receive additional nutrition and will be protected from lichen.
Also, urea is perfect as a top dressing, which must be diluted in water at the rate of 2 tbsp. l. 10 liters. The resulting spray solution must be used to treat the trunks to a height of 1.5-1.8 m.
Foliar dressing should be carried out in cloudy, calm weather. It is advisable that in the next day - two there was no precipitation. Otherwise, all your labors will be washed away by the rains.
It is necessary to spray the apple trees in early to mid-September, when the juice is still actively moving in the trunks. Later work would be impractical.
Root feeding of apple trees
Root feeding is the most common method used by almost all summer residents and gardeners to increase the yield of fruit trees. Its difference lies in the fact that organic fertilizers are applied not at the apple tree trunk, but at a distance of 50-60 cm from it along the crown perimeter. It is in this area that thin roots are located, which perfectly absorb fertilizers.
Organic fertilization method:
- To prevent diseases (rot, scab), spray the apple trees with a 2% solution of copper sulfate.
- Spread fertilizer at a distance of 50-60 cm from the trunk.
- Use a pitchfork to carefully dig up the soil. No need to dig the soil under the apple trees too deep so as not to damage the root system - 15-20 cm will be quite enough.
- Cover the trunk circle with moss, sawdust or peat.
Whichever method of fertilizing apple trees in the fall you choose, remember that any organic fertilizer should be well rotted and decomposed. Otherwise, you will cause irreparable damage to your apple trees.
Features of fertilization depending on the age of apple trees
With any method and type of fertilization, it is important to know that young seedlings need much less mineral and nutrients than large, fruit-bearing trees.
For feeding a young, from 1 to 4 years old, apple tree, 10-15 kg of manure or humus will be enough. But an adult tree will already need at least 50-60 kg of organic matter.
When applying mineral fertilizers, the dosage should be increased gradually, in accordance with the age of the trees.
So, to feed a 2-year-old apple tree with superphosphate, you will need 200 grams of fertilizer, and for a tree aged 10 years or more, at least 500 grams.
Dig shallow, 15-20 cm holes around the young apple tree at an equal distance from each other. Pour the prescribed amount of top dressing into them evenly, dividing the total dose into equal parts. Cover the holes with soil and water the trees abundantly.
Fertilizer volume depending on the variety
The apple variety is of great importance in the choice and dosage of fertilizers. This takes into account not only the age and height of the tree, but also the characteristics of the growth and location of the root system.
For example, when fertilizing dwarf or undersized apple trees, the dosage must be reduced by 25-30%.
The root system of columnar apple trees is located very close to the surface of the earth. This circumstance must be taken into account when applying fertilizers. Conventional feeding technology for such trees and seedlings is unacceptable due to the high risk of root damage.Therefore, columnar apple trees are fertilized with top dressing in liquid form, or simply scattered a dry mixture of fertilizers around the tree, gently mixed with the top layer of earth and watered abundantly.
Fruit trees can grow in one place for several decades. During the period of abundant fruiting, the soil gives them all the nutrients. Their lack immediately affects not only the yield. When the soil becomes impoverished, the trees often get sick and soon completely die. Therefore, feeding, as one of the stages of caring for an apple tree in autumn, is of no small importance.
