Plant ash can be used as fertilizer, which is basically the same. Tea is a valuable thing. After burning different plants into ashes, the content of potassium varies greatly. Plant ash produced by high temperature combustion is gray, and potassium is mainly potassium silicate, which has low solubility and poor fertilizer efficiency. When burning at low temperature, plant ash is dark gray, mainly soluble potassium carbonate, with remarkable fertilizer efficiency.

Dry the tea residue in the sun, pay attention to it, and then mix it into the soil to be used as flower fertilizer. This method is cleaner and healthier. Mix tea residue with soil at the ratio of 1:5, pile it up, sprinkle some water, and put it in a container with holes at the bottom for drainage. It can be covered with black plastic bags or other covers and exposed to the sun to increase the temperature and avoid other odors. It is suggested to use brewed tea as flower fertilizer, killing two birds with one stone. Tea is generally alkaline and can be used to synthesize the acidity and alkalinity of soil. Crush the accumulated dry tea leaves, put them in a glass jar, and add water to half of the tea leaves. Fermentation will be faster if it is placed in a place with high temperature at home.

Tea is simpler. Find a sealed container to collect the remaining tea leaves, let them stand and ferment for a day or two, and then they can be used as fertilizer water after dilution. However, it should be noted that it should not be fermented for a long time, and it should be placed for a day or two at most, and the longer the better. If the standing time is too long and bacteria grow, it will not work.

It is troublesome to use tea residue as fertilizer, which can be divided into wet method and dry method. Wet method is to collect the soaked tea residue, and it is necessary to add some acidic substances such as peel vinegar to neutralize the alkalinity of the tea residue, and then put it in a high temperature place for natural fermentation. However, it should be noted that the temperature during fermentation should not be too high, and it is best to sterilize it after it is done. Dry method refers to drying the soaked tea residue in the sun, mixing it with soil in a certain proportion, and then sprinkling water in the sun for fermentation, or laying a layer of tea residue and soil on the idle flowerpot, and so on, and then sprinkling water for fermentation.
