The dregs of traditional Chinese medicine eaten by the elderly can also be used as fertilizer. You can mix the dregs with some flower soil and put them in the bag, and then wait for a week or so, waiting for the Chinese medicine to rot, mixing and melting in the soil, then you can use them as flower fertilizer, but you should control the amount well, not too much.
