In the fall, in all gardens, in all areas, active preparation for winter begins. Gardeners still have a lot of work to do, one of their important tasks is feeding fruit trees and shrubs. Our tips site will tell you what fertilizers, how, when and in what quantities you need to apply for fruit in the fall.
It is customary to fertilize fruit trees and shrubs in the garden three times a year: in spring, before flowering, after harvesting and in autumn, when the growth of shoots slows down and the plant accumulates nutrients in the roots for the winter. Fall dressing aims to help the tree survive the winter, cope with the cold, and start blooming in spring..
Important! If you expect that the fertilizers applied in the fall will remain until spring and help the tree “wake up” – you are wrong. Everything that you add to the soil in September and early October will be safely washed out with water during the melting of snow and the first spring rains.
Let’s immediately highlight three basic rules for autumn feeding of fruits:
- Do not delay fertilization! Very soon the vegetation processes will end, the tree simply does not have time to assimilate the nutrients, and they will be wasted. Or even worse – fertilizers will provoke the continuation of the growing season, the plant will not have time to “fall asleep” before the cold weather. And this is fraught with freezing. Apply fertilizers for fruit in September, in the southern regions – until mid-October, while the weather is still good, dry.
- Remember that nitrogen stimulates vegetation processes! Therefore, leave nitrogen fertilizers for spring feeding, when they will definitely be needed and useful for fruit.
- In autumn, it is advisable to apply fertilizers dry, for digging or by loosening the soil. Useful substances will dissolve in the soil gradually, reaching the roots of plants. Leave liquid fertilizers for the spring too.
In autumn, gardeners recommend using the following fertilizers:
- Wood ash. It does not contain chlorine and nitrogen, which is important for autumn feeding. Ash will improve the structure of the soil and prevent acidification. Under an adult tree, you need at least half a bucket of wood ash, which is covered with soil from above so that it does not wash off with water.
- Phosphoric. They are aimed at the development of the root system, which is very useful for fruit plants in autumn. Phosphorus fertilizers are applied to a depth of 8 to 20 centimeters (depending on the size of the tree or bush). Under a tree you need 30 grams of fertilizer, under a bush – up to 20 grams.
- Potash. Help plants to endure winter frosts. Such fertilizers are applied to the loosened and previously watered soil. You need about 10 grams per square meter. Do not forget to cover the scattered fertilizer with soil later..
- Kalimagnesian. Also potash fertilizer, but with the addition of magnesium. Helps improve soil structure and fertility. In general, it is recommended to apply this type of fertilizer in liquid form, so many experts advise using it in the spring. Or at the end of August – beginning of September, no later.
- Combined, universal fertilizers. They are most often used if it is decided to plant seedlings in the fall. Always check the dosage on the fertilizer package..
Of course, the introduction of humus and compost in the fall will not interfere with fruit plants. Just dig up the soil around the trunk, in the area of its crown, mixing humus or compost with soil to a depth of 20 centimeters.
Important! We strongly recommend applying potash and phosphate fertilizers at the same time – together they work much more efficiently.
By the way, some gardeners refuse to dig the land in order to apply fertilizers. They dig 8-10 holes up to 20 centimeters deep in the near-trunk circle and pour dry fertilizers there, then simply burying the hole. Also an effective way to deliver nutrients closer to the plant roots.
We will give you time-tested and many gardeners’ recipes for feeding different types of fruit:
- Apple trees and pears will require 8 kilograms of compost or humus if the tree is not yet 10 years old. If there is already, we increase the dose to 20 or even 30 kilograms for trees over 20 years old. We also add up to 20 grams of potassium sulfate and about 25 grams of superphosphate.
- For currants, gooseberries and raspberries, you need 12 kilograms of humus or compost (for each bush), plus up to 30 grams of superphosphate and the same amount of potassium sulfate.
- For cherries and plums, the dose of potassium sulfate is reduced to 10 grams, superphosphate – to 20 grams. And experts recommend making humus and compost for these fruit trees diluted 1:10, just pour water and then half a liter under each tree into the already loosened soil.
Important! Experienced summer residents alternate fertilization. One fall, only compost, rotted manure, is applied, and the next year – only mineral fertilizers. This approach shows good results..
Do not neglect the autumn feeding of fruits if you want to get good yields and help the plants overwinter. And do not forget that the following works are still waiting for you in the garden in autumn:
- Whitewashing the trunks of all trees in the winter.
- Autumn pruning of fruit.
- It is advisable to mulch the trunks after fertilization so that the nutrients remain in the soil longer, and the roots are reliably protected from severe frosts.
