What fertilizer is good for cherry trees?

What fertilizer to use for cherry trees

The main fertilizer applied to cherry is organic fertilizer, which is used as base fertilizer. You can use compost, fermented manure, manure, biogas fertilizer, green manure, mud fertilizer, cake fertilizer and other farmyard manures. You can also use commercial organic fertilizers and organic compound fertilizers.

The quick-acting fertilizers used for cherries are mainly chemical fertilizers, which are used to meet the specific fertilizer needs of cherries at specific growth and development stages. They are mainly composed of phosphorus, nitrogen and potassium. Commonly used ones are diammonium phosphate, ammonium sulfate, urea, potassium sulfate and various multi-compound fertilizers.

Top dressing : For cherry top dressing in spring, high-potassium fertilizer should be applied. Applying five-in-one amino acid liquid fertilizer + high-potassium plant fertilizer can promote the growth and development of the root system and increase fruit enlargement.

How to fertilize cherry trees

Cherries pay attention to early topdressing. Fruit trees should be fertilized in time before budding and in the early stage of fruit development, mainly with quick-acting nitrogen fertilizer, and the second time with special fertilizer for fruit trees.

Cherry trees are different from other fruit trees. They cannot be fertilized in spring, so they need a large amount of water-soluble fertilizer. One acre uses 10 kg of water-soluble fertilizer. Drip irrigation is generally the best method to use, so that watering will be more even.

Spring fertilization

The time for fertilizing cherries in spring is around March 20th. When fertilizing cherries, do not use high-nitrogen fertilizers, but high-potassium fertilizers, which can improve the color of the fruit and increase the sweetness of the fruit.

Summer fertilization

In summer, cherries are fertilized with flushing fertilizers. If there is insufficient rainfall in June, the temperature is high, and the soil moisture evaporates rapidly, it is easy to cause fertilizer damage if water is not replenished in time after flushing fertilizers.

Fall Fertilization

The key to applying basal fertilizer in autumn is scientific fertilization. It is generally applied from September to late October, before the leaves fall. Early application of basal fertilizer is conducive to the maturation of fertilizer and increases the nutrient reserves in the tree.

Winter fertilization

When fertilizing cherry trees in winter, the young trees are in the crown expansion stage. During the period of vigorous nutritional growth, nitrogen fertilizer is used mainly, supplemented with an appropriate amount of phosphorus fertilizer to promote the formation of the crown.

Points to note when fertilizing cherry trees

1. If too much fertilizer is applied to cherry trees, the trees will become weak, and when the trees become weak, root rot will easily occur. When fertilizing, pay attention to the reasonable application of organic fertilizer, improve soil structure, and enhance soil permeability.

2. The leaves of cherry trees may be damaged by excessive fertilizer or excessive concentration, which is manifested by the appearance of dry brown on the tips of new leaves. Fertilization should be stopped immediately and the leaves need to be washed with plenty of water.

3. Cherries are very photophilic. When the lighting conditions are good, the trees grow healthily and the fruit set rate is relatively high, so they need to be exposed to sunlight in a timely manner after fertilizing.
