Troubleshooting
Philodendron Black Cardinal problems — and how to fix them
Philodendron Black Cardinal (Philodendron 'Black Cardinal') 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.
Leaves losing their dark colour
Too little light keeps foliage green rather than near-black. Provide brighter indirect light to bring out the deep burgundy-black tones.
Yellowing lower leaves
Usually over-watering, sometimes natural ageing of old leaves. Let the soil dry slightly between waterings and confirm the pot drains freely.
Brown leaf tips and edges
Low humidity, dry soil or fertiliser-salt build-up. Keep moisture even, raise humidity modestly and flush the soil periodically.
Faded, washed-out new leaves
Direct sun bleaches the dark foliage. Move to bright but indirect light to protect the colour.
