Troubleshooting
Calathea Freddie problems — and how to fix them
Calathea Freddie (Goeppertia concinna 'Freddie') 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.
Crispy brown leaf edges
Usually low humidity or a build-up of minerals, fluoride, chlorine or salts from tap water. Raise humidity above 50% and switch to filtered, distilled or rainwater; trim crisped edges off for looks.
Curling or rolling leaves
A thirst signal, typically from under-watering or air that is too dry. Check that the soil has not dried out completely and increase ambient humidity; leaves usually relax once moisture is restored.
Yellowing leaves
Most often overwatering or soggy, poorly drained soil leading to root rot. Let the top inch dry between waterings, ensure the pot drains freely, and avoid letting it sit in standing water.
Fertiliser / tip burn
Calatheas are easily over-fed. Excess salts brown and brittle the leaf tips. Feed only at half strength in the growing season and flush the soil with plain water until it runs clear if you have overdone it.
Spider mites
Dry indoor air invites spider mites, which cause fine stippling and webbing on the undersides of leaves. Raise humidity, rinse the foliage, and treat with insecticidal soap or neem oil if an infestation takes hold.
Faded patterning or scorched patches
Too much direct sun bleaches the contrast in the foliage and can leave bleached or burnt patches. Move the plant to bright indirect light instead.
