# What’s this black stuff on my zebra plant leaf? There were three…

What’s this black stuff on my zebra plant leaf? There were three little leaves that just recently fell off the very top of the stem. Should I cut this one off, or should I just let it fall on its own?

I got this plant back in August, when it was already leggy, (I could change him, right?!) and we were doing so well. I also have had off and on fungus gnats as well, which I’m treating with mosquito bit/neem oil watering and sticky traps. I don’t mist the leaves.

My peperomia plant next to it also has all of these dried up triangles in the leaves. Is it a pest?

Idk about the zebra plant but I think the pepperomia problem is low humidity.

Unless the leaves didn't use to be that way, then its pry damage from getting bumped or something.
