Whatever type of monstera plant you have in your home, if it's not taken care of properly and maintained, it can lose its color, and soon you'll find those green leaves turning yellow.

Most plant owners know to look out for under-watering, but there's a whole host of problems that can crop up if the plant's conditions aren't just right.

"Typical causes include overwatering, under-watering, or lack of nutrients," says gardening expert Tony O'Neill. "Excessive direct sunlight can also cause stress leading to yellowing."

To ensure your plant is getting the nutrients it needs, consider opting for natural fertilizers like seaweed and pellets or go for a chemical grow that will quickly address any deficiencies. We like these Indoor Plant Food All-Purpose Fertilizer Pellets from Amazon.
