Unfurling Monstera Leaf Brown. This viney plant is easy to maintain but even the hardy Monstera can develop problems such as brown spotting. Leaf spots leaf blights and tip burns can all mean leaves turning brown on philodendrons.
Be sure to read my blog post on underwatering and overwatering to learn how to properly water a houseplant. If you notice that your Monstera is developing light brown spots or dry crispy edges on the leaves then it may be that you are underwatering your plant. Philodendron leaves turning yellow and brown could also be caused by certain bacterial diseases.
I bought a Monstera Deliciosa and everything seemed fine for the first 3 months.
The new leaf unfurled and was weak and half brown. As this has only started the plant should be able to out grow the problem. If you notice dark brown spots on your monstera leaves this might indicate that your plants roots are rotting due to over-watering. Take care of your Monstera and it will take care of you.
