What fertilizer is good for black pine

Overview of black pine fertilization

Black pine is a plant of the genus Pinus in the Pinaceae family, also known as white bud pine. It likes light, is resistant to drought and barrenness, but is not resistant to waterlogging or cold. It is suitable for growing in sandy soil with deep soil layer, loose soil and humus. It has strong disease and insect resistance, grows slowly and has a long lifespan.

Generally speaking, if you want the black pine to grow taller, you can apply phosphorus fertilizer to it, which has a significant effect in promoting growth. Because the black pine does not require much fertilizer, you only need to apply some dilute fertilizer at ordinary times. Excessive fertilization can easily cause fertilizer loss.

What fertilizer is good for black pine

Generally speaking, it is better to apply high-efficiency fertilizer to black pine, because the growth of black pine can be divided into four stages: emergence stage, seedling stage, rapid growth stage and hardening stage, so appropriate fertilization should be carried out mainly in these four stages. When applying fertilizer, the number and amount of fertilization should be determined according to weather conditions.

In addition, it is better to apply compound fertilizer to black pine, which can be done regularly in spring and autumn. Because these two seasons are the period of rapid growth of plants, fertilization at this time can promote its rapid growth.

How to fertilize black pine to make it grow faster

Fertilization for black pine should be mainly with decomposed organic fertilizer and cake fertilizer. Nitrogen fertilizer can be mixed in spring to stimulate the growth of new branches and leaves. Compound fertilizer can be mixed in autumn to enhance the ability to resist cold, but nitrogen fertilizer should not be used alone, otherwise the new branches and leaves will be too delicate and easily affected by frost.

Fertilization in spring: Because spring is the period of vigorous growth of black pine, it is not recommended to prune black pine during normal maintenance at this time. What you need to do is to apply more fertilizer and retain more water to allow it to grow quickly and vigorously.

Autumn fertilization: Autumn fertilization for black pine usually starts in early October each year, about once every 15 days, for two consecutive times, with more phosphorus and potassium fertilizers applied to accumulate nutrients.

Points to note when applying fertilizer to black pine

1. When fertilizing black pine, you should pay attention to the surface of the pot. Don't make it too dry. If it is too dry, applying fertilizer will easily damage the roots. Don't make it too wet either. If it is too wet, the roots cannot absorb it and it will easily rot. It is most appropriate for the potting soil to be neither dry nor wet.

2. Excessive fertilization of black pine is an important reason for its leaves to turn yellow. Therefore, in order to prevent this situation, you need to be careful not to apply too much fertilizer. Once the leaves turn yellow after fertilization, you need to use water to dilute the fertilizer liquid in the potting soil.

3. After fertilizing, black pine requires sufficient light. Only by increasing the light to the plant can the black pine carry out photosynthesis better and stimulate the production of chlorophyll.
