1、 Fertilization time

1. It is best to apply fertilizer to the iron tree during its growth period. Usually between March and September, liquid fertilizer should be applied to it once a week. The concentration of fertilizer should be low, which is conducive to the more robust growth of plant branches and leaves. Fertilization must be small and repeated, and the amount of fertilization each time can not be too much. If the plant can not absorb it, the phenomenon of rotten roots will occur, which will not only fail to achieve fertilizer effect, but also affect its growth

2. After entering may, we should also apply fertilizer appropriately. At this time, we should apply some compound fertilizer to it. After entering autumn, it is necessary to suspend fertilization, because its growth speed will slow down at this time, so we must reduce fertilization or stop fertilization directly

2、 How to fertilize

When applying fertilizer during its growth, the fertilizer should be applied to the cultivated soil. Do not use too thick fertilizer or raw fertilizer. When applying fertilizer, do not touch the fertilizer with its branches and leaves. Once you touch it, spray some water, otherwise its leaves will turn yellow. Moreover, in the first 1-2 days of fertilization, don't water the plants. Keep the cultivation soil dry, so that the fertilizer efficiency can be higher
