Hi! I bought a monstera deliciosa plant just over 3 months ago, it was quite a small plant, but the seller told me the leaves would most likely start to form the splitting pattern within 2-3 weeks. The plant has since been doing great, it appears to be very healthy and has grown many new leaves, so I assume I am taking care of it correctly. Despite this, it still hasn't developed any split leaves. Any advice as to why this could be? Is there anything I can do to encourage the leaves to split, or was the seller just wrong about the time it would take? Thanks in advance.
