Calathea Yellowing And Curling Leaves

Question

I have had this calathea since this summer. It has been growing rapidly over summer but it has now started losing leaves. I hadn’t watered it for a couple of weeks while I was away, so the curling leaves made sense. I have been watering it every week since then but now more leaves are curling and the lower leaves are turning yellow.

That can be normal stress damage. I would make sure to water only when the soil is completely dry down to about 3 inches or so, or even down to 1/3 of the way down that container between waterings. The damage should remain pretty stable.

If it continues to worsen, then you can look at other things. Feeding it the proper fertilizers, and killing infections will be the next thing to look at.
