Waste tea from drinking water can be used as fertilizer after being fermented. But waste tea leaves that have not been fermented cannot be used as fertilizer. Because pour into the pot, during the fermentation process will release a lot of heat, which is adverse to the development of the root system of flowers, even the flowers will slowly burn to death.
First of all, tea and soil 1:5 mix, pile up, sprinkle a little water, put in the container will be better (there should be holes to drain), can cover with black plastic bags or other covering, the sun will be better, increase the temperature, avoid other flavor too strong. The compost is added to stabilize the whole medium, and the reaction rate is not so fast. When fermenting, pay attention to the temperature and humidity. It can't be too dry. Water it when it's too dry.
In the summer, the temperature is often too high. If the fermentation is vigorous, the temperature will reach a high temperature of around 60 degrees. The best fermentation temperature is around 40 degrees. Add water to cool down when the temperature is too high. So winter, spring fermentation rate is slow, about two months will be stable to use, summer and autumn, a month. When fermenting, it is often stirred, a little like ploughing vegetables, about once every three or four days.
