Monstera Leaves Turning Brown And Yellow. Monstera leaves turning yellow is a common sign that one of these elements is out of balance be it overwatering underwatering prolonged or insufficient exposure to light sources lack of nutritional supplements in the soil base or shock caused from repotting or propagation. If you have one yellow leaf its probably just old.
In general Monstera are pretty resilient and bounce back if the mistake is fixed soon enough. If only the lower leaves have turned yellow brown small spots appeared on them and fresh leaves are dark and small then there is not enough moisture - watering should be increased. I repotted it into a larger pot this past summer and for a while it was doing.
If it is underwatered the smallest of the monstera leaves start to turn yellow and fall off the plant in the case of monstera.
Probably the most common reason your Monstera leaves are turning yellow is from the soil being too dry. Misting the leaves of your Monstera often will increase the humidity. Light brown spots and crispy edges on monstera leaves means the monstera needs more water. These are small and dark brown spots with a yellow border appear in the leaves of the Monstera adansonii.
