What fertilizer to use for pear trees

When fertilizing pear trees, nitrogen and potassium are the most important, followed by calcium and less phosphorus. The tree's absorption of nitrogen, phosphorus and potassium has different characteristics in each growth period of the year. From spring budding to flowering and fruiting, it needs a large amount of nitrogen, potassium and phosphorus.

How to fertilize pear trees

The base fertilizer for pear trees is usually applied in autumn. At this time, organic fertilizer is the main type of fertilizer. The amount and method of fertilizer for young trees and mature branches are different, so it is necessary to have a reasonable grasp of this.

Top dressing of pear trees can be divided into three to four times, and different fertilizers can be applied at different growth stages. Young seedlings can be fertilized during the budding period, the new shoot growth period, and after the new shoots stop growing. Each time of fertilization is mainly based on quick-acting nitrogen fertilizer, while adult fertilizers are mainly applied before flowering fertilizer and fruit-wrapping fertilizer.

Spring fertilization

Pear trees consume a lot of nutrients during budding, flowering and new shoot growth in spring, so topdressing is necessary before budding. After the flowers fall and until the young fruits begin to swell, the new shoots begin to grow rapidly and require a large amount of fertilizer, so topdressing can be done again, mainly applying urea and appropriately adding potassium fertilizer.

Summer fertilization

Between May and June in summer, before the flower buds differentiate, pear trees should be topdressed with special fertilizers mainly containing phosphorus and potassium and supplemented with nitrogen. This can provide the fruit with sufficient nutrients and promote flowering.

Fall Fertilization

Base fertilizer needs to be applied in autumn. The fertilization period for pear trees varies from country to country, but it is not advisable to apply too much fertilizer in autumn, otherwise the aboveground part will grow excessively, which will reduce the tree's stored nutrients and make it susceptible to frost damage.

Winter fertilization

Fertilizers should be mainly farmyard manure containing more organic matter. Commonly used fertilizers include manure, compost, cake fertilizer, green manure and soil manure, which are applied after decomposition. Micro-fertilizers should also be applied in a targeted manner.

Points to note when fertilizing pear trees

1. The fertilizers applied are different at different growth stages of the pear tree. During the entire growth stage of the pear tree, the demand for nitrogen fertilizer and potassium fertilizer is the highest, followed by calcium fertilizer and boron fertilizer, and the demand for phosphorus fertilizer is relatively low.

2. Fertilizer damage to pear trees can be said to be a physiological disease of pear trees caused by fertilization. Therefore, when the pear trees are over-fertilized or raw fertilizers are applied, the fruits need to be watered in large quantities.

3. Pear trees are a light-loving species, so after fertilizing, they need to be exposed to sunlight in time, but strong sunlight at noon should be avoided. It is best to choose to fertilize in the evening on a sunny day.
