Help! I have some browning on my monstera adansonii leaves. This is most likely because it was kept in a small pot for way too long. When I repotted, the plant was very root-bound. Since then it has grown several new leaves and looks healthy, but I don't know what to do about the old brown leaves. I trimmed the brown parts off, but the edges turned brown/yellow again. Do I need to cut the entire leaf off and if so, where do I cut? It is the first and only leaf growing from the stem.
