Monstera Adansonii Leaves Falling Off. Well you cant really. Bacterial and fungal diseases can cause leaf spots on Monstera.
Some house plant pests specifically spider mites and aphids can cause yellowing leaves. A Monstera that is too young wont fenestrate until it is about three years old. You may notice slowed or even halted growth.
A good hint is smelling something rotting around your plant and if it doesnt have that stench gently remove the soil to inspect the soil.
Those old leaves turn yellow and eventually brown and then fall off or are clipped from the plant. I got this cutting with roots in December. You may notice slowed or even halted growth. The discolored parts may range from white or yellow to a lighter green against the natural green of the leaves.
