This Monstera deliciosa had a yellow leaf, that I removed. I think it lacks light. It's a new growth of an old plant.

    Guttation. The plant secretes excess minerals in liquid through pores in the leaves. The water evaporates and leaves blobs of minerals and proteins. It’s harmless

    Its guttation, as noted by the first commenter. Harmless on its own, but it can be a sign of too much water. A yellow leaf is also a sign of too much water.

    Monstera roots need air as well as water, so we aim for damp soil, never wet. This means waiting for the top inch or 2 of soil to dry out between waterings, and don’t let excess water hang out inside or under the pot.

    Highly recommend watering with distilled water if you have “hard water” in your area. Better for the plants, and you’ll see less mineral buildup on the leaves/stems.

    Interesting… other posters are saying this is guttation. I’ve seen guttation, sometimes when I overdo it with the watering, and often when I brush past the pothos I grow out of my aquariums. It’s always just water, not waxy white stuff. Why the difference?

    Edit: “Guttation causes is not generally harmful to the plant. At worst, as the drop of sap dries, it may leave behind a white deposit (coming from minerals and sugars exuded along with the water) or a particle of dried black sap. In nature, bees often seek out these drops for the sugar they contain.” I had to go look because I was curious. So it’s residue left over from guttation I gather. Mine just doesn’t have residue.

  6. Many plants produce certain types epicuticular waxes, thats what you see here. No, its not minerals, its not bugs, it’s just normal thing your plant does 😊
