Feeding apple trees has its own nuances. You need to know that young and mature apple trees need different nutrition. It is these differences that we will consider.
The feeding of young apple trees begins from the first year after planting: root - in early spring, foliar - later (one in May, one in June). For root dressing in a bucket of water (10 l), 50 g of urea is diluted (2 tbsp. Tablespoons). Under each young tree, 15 liters of mortar (one and a half buckets) are poured. For foliar feeding, it is better to purchase ready-made liquid preparations, such as Effekton, Sodium Humate (a tablespoon of fertilizer in a bucket of water). To feed a young apple tree, 2 liters of the resulting solution will be required.
Starting next year, young (not yet fruiting apple trees) are additionally fed with phosphorus and potassium in September (two buckets of water are poured under one young tree in which 4 tbsp. Of phosphorus-potassium preparation are previously dissolved).
The root top dressing of apple trees is carried out with a deviation of 60 cm from the tree (not under the trunk). Do not forget about the location of the roots. Similarly, top dressing of
colon-shaped apple trees (strong-growing) should take place. Fertilizing adult apple trees should be carried out throughout the entire growing season (four times per season). For the first feeding, experienced gardeners recommend using urea (500 g) and humus (5 buckets). This composition crumbles around a tree (already bearing fruit) in the second half of April.
The second feeding of apple trees is carried out when the buds appeared (the beginning of flowering). In the absence of rains (or if there are few), top dressing is introduced in a liquid state. A 200-liter barrel will require potassium sulfate (800 g), superphosphate (kilogram packaging), bird droppings (5 l) or slurry (10 l). The last components can be completely replaced with urea (about 500 g) or the drug "Effekton" (two bottles). All this is mixed and left for a week. The feeding rate is 40 liters for one fruiting tree. When watering, you should step back at least 50 cm from the stem (trunk). Before feeding and after the tree is watered.
A third top dressing will be required in the fruit loading phase. In a two hundred liter barrel, sodium humate (20 g) and nitrophoska (1 kg) are diluted. Consumption per tree - 3 buckets.
The fourth top dressing is needed already in the fall (carried out after harvesting). If the rainy autumn, top dressing can be applied in a dry form - 300 g each of superphosphate and sodium sulfate. If there is little rain, the same amount of fertilizer is diluted with water.
Mature apple trees and foliar top dressing are very fond of. It is carried out with a urea solution three times per season. The first time they spray it when the apple tree is just starting to bloom. Between dressings should be a break of three weeks. To obtain a solution, two tablespoons of urea are bred in a bucket of water. Not only the leaves are wetted, but also the skeletal branches, and the trunk.
But this does not end the feeding of apple trees. Additionally, it is not bad to spray with such microelements as zinc, molybdenum, manganese, boron, copper, magnesium. The listed elements are contained in the composition of mineral fertilizers, such as Kemira (20 g of composition per bucket of water). Wood ash is also very useful (a glass of ash is poured with boiling water, then the total volume is brought up to 10 l).
