The residue left after decoction of Chinese herbal medicine is a good fertilizer for growing flowers. Most traditional Chinese medicines are composed of roots, stems, leaves, flowers, fruits, seeds of plants, limbs, organs, and shells of birds, animals, insects, and fish, as well as some minerals, rich organic matter, and inorganic substances. Nitrogen, phosphorus, potassium and other fertilizers needed for plant growth are found in traditional Chinese medicine residues. Using traditional Chinese medicine dregs as fertilizer to plant flowers can promote growth. Not only will the plants have lush stems and leaves, but the flowers will also bloom particularly beautifully. The main benefits of using traditional Chinese medicine dregs as fertilizer are: (1) Changing the unhygienic phenomenon of dumping medicine dregs indiscriminately in the past. (2) Increase the organic fertilizer required by plants to promote their growth. (3) Turn waste into valuable humus for potted flowers. If you use Chinese medicine residue as flower fertilizer, you must put the Chinese medicine residue into a container such as a jar or a bowl, mix it with soil, add some water, and let it soak for a period of time until the medicine residue rots and turns into humus before use. Generally, the medicinal residue is put into the pot as a base fertilizer, and after the plants are planted, it is covered with a layer of soil. It can be added at any time according to the needs of the plant's growth process, but the medicinal residue fertilizer should be used in an appropriate amount. If it is convenient for residents, it is best to pour the traditional Chinese medicine dregs at the roots of hedges in the flower beds near the house, or at the roots of large trees. In this way, the organic nutrients after the traditional Chinese medicine dregs are weathered and decomposed by wind, sun, and rain will not only increase with the growth of plants, It is gradually absorbed, and the remaining medicinal residue can improve the soil
