I heard from a friend that tea leaves act as a great fertilizer. Because of this, I have started a "you must drink a cup of tea everyday." The problem is though is that with every teabag, you must cut it open and get the remains from it. I think that you do the same with tea bags as with coffee grounds; you sprinkle it over your plants. This is supposed to help your plants produce more fruit and/or grow taller. Using tea bags, probably doesn't hurt your plants so it doesn't hurt to try it. I am going to incorporate my tea bags into my compost bin so the soil is richer. Hopefully, this will work!
