I was given a Montsera(?) cutting and I don’t really know if this leaf is too wrinkled? It’s a minefield trying to read about and understand if I have over or under watered. I just don’t know what this plant actually wants.
My usual approach is to assume I have over watered if a plant looks unhappy, but I don’t know if these bounce back after a period of under watering, if I hold back on watering more now.
Water when it gets wrinkly, but don’t let the soil stay saturated forever it can get root rot. Have you seen the roots at all and how long have you had the plant? If it was potted when you got it, underdeveloped or immature roots could also contribute to rot
