Philodendron Leaves Turning Black
Hello! Here is a picture of a new leaf that has gone black on my Philodendron Split Leaf plant; also, there is a dark spot on another leaf. Can you let me know whats wrong with it? I water it once a week or so, and its in a bright room, but no direct sunlight. Any help would be greatly appreciated!! Thanks! Alice
It looks like your plant has a bacterial plant disease called leaf spot. Cut off the diseased leaves and then wash the scissors in a bleach solution. Put the plant in cool, dry location (no more than 70°) with bright indirect light. Do not mist the plant! Water from below so leaves never get wet. Hopefully this will stop the spread of the disease to any new leaves.
