Fertilization technique of bonsai in autumn

The general characteristic of tree growth is that the shoot has been Lignified in spring and summer, and a new root and leaf system has been formed, which increases the assimilation area of trees and accumulates nutrients for autumn shoot and flower bud differentiation. The autumn shoot growth and flower bud differentiation of evergreen trees are carried out at the same time, the competition for nutrient distribution is fierce, vegetative growth is better than reproductive growth, reproductive growth consumption is greater than vegetative growth, and can inhibit each other.

The management of autumn bonsai is an important period, and soil, water, fertilizer and light should be strengthened. Evergreen trees should also pick their hearts to promote the Lignification of autumn branches as soon as possible so as to create conditions for overwintering. Conifers and deciduous trees sprout but not sprout in autumn, so it is necessary to promote their dormancy in late autumn so as not to waste nutrients and affect their smooth overwintering.

Fertilizers should be timely and appropriate, and should be diluted many times in early autumn. Potted friends can use jade fat to be convenient, hygienic, without any unpleasant smell and full of fertility. Less application in the Mid-Autumn Festival and controlled fertilization in late autumn should not promote late autumn shoots. This use of fertilizer can promote early growth of autumn shoots, so that vegetative growth and reproductive growth are carried out at the same time, and there will be many leaves and flowers and fruits in the coming year. If the tree is in good condition and there is more autumn fertilizer, spring flowers may bloom in autumn. My black persimmon and Luohansong have spring flowers and autumn blossoms and autumn fruits for many times. Early application of autumn fertilizer is widely used in fruit production, but tree stump management is more precise, so autumn fertilizer should be applied early.

How to fertilize bonsai? In general, thin fertilizer is applied frequently:

1. Pomegranate, begonia, wisteria, Firethorn, Phyllostachys pubescens and other flowers and bonsai should be fertilized with more phosphorus and potash fertilizer.

2. Five-needle pine, yellow poplar pile, ivy and other foliage bonsai should be based on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer.

3, pine and cypress bonsai, can be self-made bean cake cooked water diluted fertilizer, 3 times a year.

4. Fertilization can be applied in spring, summer and autumn, and stop in winter dormancy.

5. Trees that have just come into the pot cannot be fertilized because their new roots have not yet grown.

6. Liquid fertilizer should not be too thick and must be diluted before it can be used, otherwise it will cause fertilizer damage.

7. Organic fertilizer and cake fertilizer must be fully ripened before they can be used, otherwise they will ferment in the basin soil to produce high temperature and burn the roots.

8. Do not sprinkle liquid fertilizer and water on the leaves as topdressing.

10. Fertilizing is good in sunny days, but not in rainy days and rainy seasons.
