Shrub and tree cherries in the garden grow in one place for several decades. Fertilizing cherries in the fall is important for the plant. Let's try to understand its features.

Why do you need to feed?
The end of the growing season and the approaching dormant season is a crucial time for gardeners. Cherry trees need some help before winter comes and some must-do activities. Top dressing is one of them. Indeed, during the growing season, the plant actively absorbed both organic and mineral substances from the soil.
In addition, some of the nutrients were washed out of the ground by natural precipitation and additional irrigation, and some were simply destroyed over time. Here are the main reasons for feeding in the fall:
- restoration of soil fertility after fruiting
- disease prevention
- preparing wood for winter frosts
- strengthening vegetative and generative kidneys
Cherry is one of the plants that blooms quite early, so the supply of nutrients should already be in the soil by the time the flowers bloom. After all, abundant flowering is the key to a good harvest. In addition, autumn feeding will help the growth and development of cherries in the next growing season.
The success of autumn fertilization depends on the correct timing for this event.
When to fertilize cherries?
The timing of autumn dressings is important for cherries because too late the introduction of nutrients will not have time to bring great benefits to the tree. Indeed, closer to winter, the plant stops feeding and the movement of juices and it will go "hungry" in the winter. Too early feeding will also not be very effective, since some of the nutrients may simply be destroyed, and some will be misused by the cherry, since the tree is still actively feeding and growing.
When choosing the optimal timing for fertilizing cherries in the fall, it is imperative to take into account the local climatic and weather characteristics. In some regions, where the autumn period is very short and the freezing of the soil occurs early, the so-called autumn feeding should be completed by the end of August.
However, in most areas with a temperate climate, this event begins in early September and must be completed by September 21-25.
If the climate is characterized by a long and warm autumn, then you can feed the cherries until the first days of October. Important! In the first two years after planting, cherries do not need autumn feeding. In order for the fertilizing to bring the maximum benefit to the cherries and become the key to the future harvest, the plants need to take preparatory measures.
How to prepare a plant?
Before fertilizing, you need to inspect the tree and remove dried, damaged branches. If the diameter of the branches to be removed is too large, then treat the place of cuts with special compounds. After that, from the near-trunk circle, with a diameter slightly larger than the diameter of the crown, all weeds are torn out or removed manually.
You need to work with a hoe very carefully, already at a depth of about 20 cm, cherry trees can have roots. As soon as the trunk circle is free of weeds and plant debris, it is necessary to loosen the soil. The depth of loosening should not be more than 15 cm. A mandatory measure before applying top dressing is abundant watering of the trees.
Under each tree or bush, you need to pour at least 5-6 buckets of water if their age is from 3 to 6 years. If the plants are older than seven years, then the amount of water increases to 8 - 10 buckets. The water should soak well all the soil in the root area. When watering trees growing on a slope, you need to slightly increase the irrigation rate with the expectation that part of the water will flow down. Watering should be done 1-2 days before fertilizing.
Basic feeding rules
To get the most out of your cherries, there are a few basic rules to follow.
Important! When starting to fertilize cherry trees in autumn, you need to take into account that nitrogen fertilizers cannot be applied in the fall. Its excess can disrupt the normal entry of plants during winter dormancy. In order to increase the content of minerals in the soil in the fall, it is necessary to apply phosphorus and potassium fertilizers under the cherry.
Video on the correct care for cherries:
Ideally, the rate of application of mineral fertilizers should be calculated after laboratory studies of the garden soil. In the absence of such an opportunity, the introduction of fertilizing under trees aged 4-11 years is recommended in the following quantities:
- superphosphate in the trunk circle 300 g
- calcium chloride - 180 g
If cherries are over 11 years old, then the amount of fertilizer is increased to 450 g and 250 g, respectively. Fertilizers are applied both in liquid and dry form. The soil under the tree is either spilled with a fertilizer solution, or they are evenly scattered over the entire area. Important! Potash and phosphorus fertilizers are not applied to trees younger than three years old inclusive.
Cherry trees are responsive to calcium input. Its source for plants is crushed chalk. It is most correct to add up to 1.0 - 1.5 kg of chalk along the outer circumference of the trunk circle. Before that, the chalk can be poured with water to the state of a liquid chatterbox and pour it over the tree in a circle.
Important! The introduction of chalk should not be confused with liming the soil. If the gardener is against the use of chemically obtained fertilizers, then the introduction of wood ash will be a good mineral support for cherries. It can be applied while loosening the soil.
The depth of ash embedding in the ground is up to 10 cm. For an adult cherry, about one and a half kg of wood ash per square meter is enough. m. Iron deficiency can be compensated by autumn spraying and whitewashing of trunks with a solution of ferrous sulfate.
From the fourth year of life, cherries can be fed with organics in the fall. This plant is very fond of rotted manure or compost. The frequency of introducing organic matter in the fall is once every three years. The norm is one bucket per sq. square meter. Compliance with the above rules will be the key to a safe wintering and future good flowering and an excellent harvest.
