How to fertilize Forsythia? Do you need to fertilize the transplanted seedlings?

1. How to fertilize Forsythia

1. Fertilization in spring and autumn: Spring and autumn are the peak growth seasons for Forsythia. Its demand for fertilizer is relatively high in these two seasons, so fertilization must be carried out in time. Generally, compound fertilizer should be applied every 15 to 20 days to promote vigorous growth of the 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 rate is slow, it is still necessary to apply fertilizer in moderation. At this time, the main type of fertilizer to be applied is decomposed cake fertilizer, which should be combined with weeding and loosening the soil. This can help it survive the winter and also promote better and more flowering in the coming year.

2. Precautions for fertilizing Forsythia

The temperature is relatively high in summer, so fertilizer treatment should be stopped and should not be continued. It is difficult for plants to absorb fertilizer under high temperature conditions. Applying fertilizer at this time can easily burn the roots and hinder growth. In addition, it is best to dilute the fertilizer before applying it in the other three seasons, otherwise it is easy to burn the plants.

3. Do I need to fertilize the seedlings when I transplant them?

Do not apply fertilizer when transplanting Forsythia seedlings. Because the plants have just been planted, they are in a new environment and have not yet resumed growth. Applying fertilizer at this time can easily cause damage to the root system. If you want to fertilize, you should wait until the seedlings resume growth, at least one week later. When applying fertilizer, be sure to dilute it before applying so that the seedlings can absorb it faster and promote rooting.
