Any suggestions on how to help nurture my striped calathea back to good health? I haven’t had it for very long, maybe a few months, it’s in its original pot I bought it in, it gets partial sun in my bathroom, near shower so also gets some humidity/steam there as it states humidity helps. I try to water in every two weeks or so. Pot has drainage. I’ve moved it closer to the window to get some direct light vs only indirect light. Does it need fertilizer? Should I cut off the yellowing/brown dry leaves? Thank you for helping me with this beautiful gal!
