Monstera Yellow Spots On Leaves. When spores are carried off and have settled on the leaves they start reproducing. In the winter you can allow your plant to dry out a little more between waterings.
In this case the yellow leaves should be removed and moisture should be reduced. Soil should remain damp but not wet. At the same time rotted roots should be removed and the rest sprinkled with charcoal.
If you notice the lower leaves especially the oldest leaves are turning yellow go ahead and feel the soil.
These are most likely to be small leaves that are closer to the base of the plant. Yellow Monstera leaves can be a sign of overwatering. Consequently exposure to low humidity can make their leaves turn brown. Before giving your Monstera a drink check to make sure it needs water by sticking your finger a few inches down into the soil.
