1、 How to fertilize Forsythia

1. Fertilization in spring and Autumn: spring and autumn are the peak growth seasons of Forsythia suspensa. The demand for fertilizer in these two seasons is relatively high, so fertilization should be carried out in time. Generally, compound fertilizer should be applied every 15 to 20 days to promote the vigorous growth of plants, which may also promote the formation and growth of flower buds

2. Fertilization in winter: Although the temperature in winter is relatively low and the growth speed is slow, appropriate fertilization should also be applied. At this time, fertilization is mainly to apply the rotten cake fertilizer, which should be combined with weeding and soil loosening, which can help it survive the winter and promote better and more flowers in the coming year

2、 Precautions for fertilization of Forsythia suspensa

The temperature in summer is relatively high, so it is necessary to stop fertilizer treatment and can not continue to be applied. It is difficult for plants to absorb fertilizer under high temperature. At this time, if fertilization is easy to burn roots, it will hinder growth. In addition, it is best to apply fertilizer after dilution in the other three seasons, otherwise it is easy to burn the plant

3、 Do you need fertilization for seedling transplantation

Do not apply fertilizer when transplanting Forsythia seedlings. Because just planted, the plant is in a new environment and has not recovered its growth. At this time, fertilization is easy to cause damage to the root system. If you want to fertilize, you should wait until the seedlings resume growth, at least a week later. When applying fertilizer, pay attention to apply it after dilution, so that the seedlings can be absorbed faster and promote rooting
