At home, we drink beverages like tea or coffee every day. Sometimes we forget to pour out the leftover tea or coffee and just leave it in a cup or kettle. In such cases, some people think of using it to water plants to reduce waste. Can overnight tea be used to water plants? What effect does it have on plants? Let's explore this below.
What is overnight tea?
Overnight tea refers to the leftover tea left in a cup or kettle, usually for a night or longer. Due to the long storage time, the components in the tea leaves gradually dissolve in the water, making the tea more concentrated.
