Calathea Orbifolia problems & how to fix them

Goeppertia orbifolia

Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Calathea Orbifolia problems, what usually causes them, and how to turn things around.

Common problems

Crispy tips (low humidity)

Tap water minerals, low humidity, or fertilizer salts show up fast as brown edges on these big leaves. Brown, dry leaf tips caused by air that is too dry for the plant, common in heated or air-conditioned rooms. Existing crispy tips never turn green again, but with higher humidity new growth should come in clean within a few weeks.

Spider mites

The thin, broad leaves are highly susceptible in dry winter air. Tiny sap-sucking mites that thrive in warm, dry air and leave fine webbing and speckled leaves. Caught early they are very treatable; most plants recover fully within 3-4 weeks of consistent treatment.

Root rot

Constant moisture without drainage or airflow tips it from happy to rotting. A fungal or bacterial infection of the roots, almost always triggered by soil staying wet too long. Caught early, most plants recover within a few weeks after repotting; if most roots are already mushy, recovery is uncertain.

Fungus gnats

The always-moist surface soil is prime gnat breeding ground. Small dark flies that breed in constantly moist potting soil; the adults are harmless but annoying, while larvae can nibble roots of seedlings and weak plants. Very treatable by drying out the soil; expect the flies to fade over 2-3 weeks.

The mistakes that most often kill it

  • Hard tap water and dry air — the leaves brown edge-in until nothing pristine remains.
  • Letting the root ball dry out completely even once.
  • Cold drafts or rooms below 16 C.
