Is fertilization important? Fertilization is very important for bonsai. As we all know, bonsai is basically a shallow pot plant with ornamental value, and there is less pot soil. When stumps grow, the nutrients they can absorb are limited. Except that some stumps inhibit growth, bonsai under normal maintenance should make stumps grow healthily and vigorously. Fertilization is one of the basic tasks. How to do this work well is directly related to the growth of bonsai. I will share with you the scientific fertilization methods from the aspects of fertilization amount, fertilization types and fertilization time.

fertilization rate
When applying fertilizer to stump bonsai, it is necessary to maintain a small amount of fertilization for many times, and the amount of fertilization should be less each time, preferably diluting fertilizer. Some large piles need more fertilization, and some small piles need less fertilization. According to tree species, they like to apply more fertilizer, but they are barren-tolerant and apply less.
Generally speaking, from beginning of spring to beginning of autumn, it is the growing period of stumps. In the meantime, we can apply fertilizer every 10 day, preferably dilute fertilizer water, mixed with 3% fertilizer and 7% water, so that the effect of external fertilization is very good. After autumn, the fertilization cycle is reduced to once every 20 days. Since then, the fertilization cycle has been gradually extended, and fertilization has stopped after winter.

Fertilization type
Stump bonsai needs nutrients that cannot be separated from nitrogen, phosphorus and potassium. Nitrogen fertilizer can promote plants to flourish and have more pregnant buds. Nitrogen-rich fertilizers include bean cake, urea, human and animal manure, etc. Phosphate fertilizer can promote bright colors and huge fruits. Phosphate-rich materials such as aggregate, eggshell, potassium dihydrogen phosphate, etc. The role of potassium fertilizer can make the roots of plants developed, the waterline strong, and the plants firm and not lodging. Commonly used fertilizers rich in potassium, such as plant ash and potassium dihydrogen phosphate.
Knowing the function of the main elements, when applying fertilizer, we should match the types of fertilization according to the characteristics of tree species and the current situation of plant growth. In addition, in each stage of stump growth, the proportion of fertilization types is different, so it needs to be used flexibly. Like the growth period, apply more nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. More phosphorus and potassium fertilizers should be applied in the flowering and fruiting period, and urea should be applied in the late fruiting period to help the fruits mature and increase luster.

Fertilization time
Fertilization time refers to when fertilization is most appropriate. For example, a newly planted or cultivated stump bonsai can't be fertilized because the root system is damaged to varying degrees. Wait until the next spring or early summer, when the roots have resumed to grow vigorously, and then apply fertilizer. For example, after autumn, the growth of stump bonsai slows down, so fertilization should be reduced. Winter basically enters a dormant period, and it is even more impossible to fertilize.
It should also be noted that fertilization is not allowed in rainy days and at noon in summer. Fertilization loses quickly in rainy days, and it will also hurt the roots. Water evaporates quickly at high temperature, and the diluted liquid fertilizer will be too high in concentration because of water evaporation, resulting in root burning. The best fertilization time is cloudy and evening. It should also be noted that when fertilizing, if there are too many weeds in the pot, it is best to pull them out and loosen the soil, which will help the fertilizer to penetrate into the soil as soon as possible and promote the rapid decomposition and absorption of the fertilizer.
I'm Juanzi, a girl from the "greenhouse". I know how to fertilize. If I can fertilize well, I still need to work hard. It is often said that it takes ten years to water and one year to fertilize. So much for the discussion about fertilizing bonsai. Don't forget to give Juanzi one-click three links!
