Is coffie good for your plant?

Answer 1

It depends on the plant... most plants will love the increase in acidity (watering removes some of the acid from the soil, but fertilizing every time you water is no good). Once or twice a month, throw some used coffee grounds around the plant (on the soil, not the plant itself). Just make sure that you don't put the coffee grounds on plants like tomatoes (they love 'sweet' soil-whenever fertilizing tomatoes, you should also add some pelletized lime to make the soil more alkalytic).
