Question: why are the leaves on my indoor plant turning black?
Answer: Improper watering causes plants leaves to turn black and drop prematurely, but this can happen if you water too much, and can also happen if you water too little. ... Ensure the soil around the plant remains evenly moist at all times, and when the top 1 to 1 1/2 inches of the soil feels dry, you know you're good to water.
