Why is my Monstera turning brown?
Keeping this in consideration, should I cut brown leaves off Monstera?
Brown tips can be a sign of overwatering, but if this is indicated you'll get yellow leaves too. If the brown effect appears on its own then it's almost certainly caused by very dry air, cut the dead brown bits off and increase humidity to prevent further damage.
Additionally, what is wrong with my Monstera?
Monstera deliciosa leaves can turn yellow if they are overwatered or undernourished. If this happens, refrain from watering your plant until you feel its soil dry. If the problem persists, repot your monstera in fresh soil. Brown leaf tips or edges can result from dry air and low humidity.
Cheese plants should be watered only when the soil has more or less dried out. Floppy leaves that turn brown are most likely to have been caused by draughts and frequent temperature fluctuations. If this happens, cut off the brown leaves and move the plant to a warmer area.
