Monstera seems to have a disease, help identify?
Hello,

I just purchased a new monstera about a month ago, and just recently noticed that the bottom, smaller leaves began turning yellow. Upon further inspection, I noticed many small black spots on the leaf as well (both top and underside). As I look at the additional lower leaves, there are some green ones that have the same black spots but are not yellow. I worry that there’s is a disease  spreading and need advice how to fix before it’s too late!

    Paris Lalicata Hi Chelsea! Would you be able to share a photo of the entire plant, as well as the leaves that also have these black spots but no yellowing?

        Paris Lalicata Hi Chelsea! Since it appears that the rest of the plant is very happy, and healthy I wouldn't be concerned about the one yellowing leaf that dropped. It seems like this could've been caused by an excessive moisture issue that caused the leaf to yellow, as well as plant cells bursting in the leaves (spots). I would ensure that the plant is exposed to plenty of bright indirect light, and allow the soil to dry out between waterings. If the plant has become root bound or hasn't had its soil replenished for about 8 months then I'd recommend repotting it into a container that is 1-2 inches larger as well!

          Chelsea Thanks, Paris! I'm keeping an eye on the other leaves that are still green with brown spots. If they start yellowing, then I'll escalate the issue. For now, I agree that the rest of the plant seems to be pretty happy so I'll leave as is!
