Do you have expired teas either in loose leaf form or in tea bags? Don’t throw it to the dustbin/trash, I repeat don’t, (that’s if you have plants or a garden anyways).
So put the expired teas (any kind of tea/herbal infusion), add it to the soil and watch your plants grow better.
So basically expired teas are still a little beneficially. You can also use tea bags or tea leaf you have finished steeping/drinking (I almost always for to do this one)
And I don’t know why I woke with a strong craving for a very strong cup of black tea today, lol.
