Troubleshooting
Philodendron Cobra problems — and how to fix them
Philodendron Cobra (Philodendron 'Cobra') 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.
Reverting to solid green
Insufficient light causes the plant to favour green, chlorophyll-rich leaves. Move to brighter indirect light and prune back fully green growth to encourage variegation.
Browning or burning white sections
All-white variegated zones lack protection and scorch easily. Avoid direct sun and keep humidity up to reduce crispy patches.
Slow growth and small leaves
Normal for highly variegated plants, but worsened by low light or no support. Add a moss pole and improve light to maximise leaf size.
Root rot from overwatering
Variegated leaves transpire less, so the mix dries slowly. Use a chunky, fast-draining blend and wait until the surface dries before watering.
