Recently, the editorial department of Jiande received a letter from enthusiastic reader Wang Zengshun. He made a suggestion as to whether the fallen leaves could be used as fertilizer. The contents of the letter are as follows:

Editorial comrades:

I see some unscientific management in the Baisha Park activities every year. The cherry blossoms that fall in the spring, the autumn leaves, the lawn mowing, etc., must be cleared and transported by workers. It is suggested that the garden management department should change the fallen leaves to the roots of the trees, reduce the amount of transportation, and increase the organic fertilizer, so that it can save labor and save.

To this end, the reporter interviewed the head of the Greening Management Division of the Municipal Garden Management Office. According to her, it is not appropriate to use landscaping fertilizers for falling flowers and fallen leaves.

The main reason is that the fallen leaves are too much, which easily affects the permeability of the soil and is not conducive to the growth of plants. In addition, decaying fallen leaves produce heat during the fermentation process, which affects the growth of plant roots. Moreover, the decaying fallen leaves piles are prone to various pests. When the fallen leaves are rotted and fermented, they will produce some unpleasant gas, affecting the morning exercise and leisure in the park. Therefore, in landscaping, it is not used as a green manure for fallen leaves. Finally, Mr. Xin was very grateful to Wang Zengshun for his comments and hoped that the general public would give more suggestions on landscaping.
