1. Seedling stage: this stage is the beginning of plant growth, which can not be satisfied with only a single fertilizer. Therefore, it is necessary to apply compound fertilizer with balanced nutrition. The interval of fertilization is about once a week.
2. Vigorous growth period: the amount of fertilizer needed in this period has changed, and the content of nitrogen should be reduced. If nitrogen fertilizer is used too much, it will damage the health of the plant, for example, the leaves will be rolled, which will affect the ornamental effect of the flowers.
3. Before flowering: flowering is a period of special need for fertilizer, because flowering needs more nutrients, if not supplemented in time, it will reduce the number of flowering, or not flowering at all. At this time, the fertilizer needed is also phosphate fertilizer and potassium fertilizer, which are conducive to the growth of flower buds.
1. Do not apply fertilizer in summer, winter and flowering period, or sprout lateral branches and wither flowers in advance.
2. Pay attention to "apply thin fertilizer frequently", that is, do not apply too high concentration of fertilizer, otherwise it will cause fertilizer damage, bring a series of damages to the plant, and then apply more fertilizer. But also do not fertilize the times do not too much, the frequency of seven to ten days to apply once.
3. When spraying fertilizer on the leaf surface, pay attention to spraying both sides of the front and the back, do not miss spraying, and spray evenly.
