Monstera Leaf Black Spots. If your Monstera leaves are turning black its time to take action quickly. HI I recently a month or two ago bought my first monstera plant.
The biggest thing that can wreck your monsteras leaves is over or underwatering. Before you diagnose rest assured that you can remove any yellow or brown leaves by simply cutting. The two most common reasons for brown spots on Monstera are.
Relative humidity between 50-60 is best suited for most of the houseplants.
Dark brown spots on monstera leaves is a good indication of the plant getting too much water. Once spots develop the leaves are damaged forever. Your plant isnt doomed or anything but blackening is an indication of issues on the serious side. So monstera tends to need more water than usual.
