My Monstera Deliciosa Leaves Are Turning Black At The Edges

Question

The plant is potted, and kept “ damp”, by watering week
Y. It is in a lightship area, but not direct sun light. Some of the edges of the leaves are tuning black, photo attached.
Any ideas ?

Answer 1

Dark edges can be from too much or too little water. Is your pot well drained and all water removed from tray after it drains? They don't like to sit in water. Not enough humidity can also cause brown edges. These plants need high humidity.

Because your plant's spots have the yellow halos, I think it may be a bacterial infection. Remove all the leaves with spots and destroy them. (But not all the leaves.) Then look at the care articles below and see if any of the cultural tips will prevent the spots from returning.
