Calathea Setosa problems — and how to fix them
Calathea Setosa (Ctenanthe setosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Brown leaf edges
Low humidity or tap-water minerals/fluoride. Use distilled or rainwater and raise humidity.
Curling or rolled leaves
Underwatering, cold, or dry air; check soil moisture and keep away from draughts and vents.
Yellowing leaves
Overwatering or compacted, poorly draining soil. Let the surface dry and ensure free drainage.
Spider mites
Dry indoor air invites mites under the large leaves. Inspect, rinse foliage, and treat with insecticidal soap if found.
