Troubleshooting
Philodendron Gigas problems — and how to fix them
Philodendron Gigas (Philodendron gigas) 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.
Yellowing leaves
Usually overwatering or soggy mix; also possible with nutrient shortage or over-fertilizing. Check that the top inches dry between waterings and that the pot drains freely.
Brown, crispy leaf edges
A sign of low humidity or letting the plant dry out too far. Raise humidity to 60%+ and keep watering consistent.
Faded or scorched leaf patches
Direct sun bleaches and burns the velvety surface. Move to bright indirect light behind a sheer curtain.
Spider mites and thrips
The large velvety leaves attract sap-sucking pests, especially in dry air. Inspect regularly, wipe leaves, and treat with insecticidal soap or neem if found.
Mealybugs and scale
Appear as white cottony tufts or brown bumps along stems and leaf joints. Dab with diluted alcohol and treat repeatedly until cleared.
Root rot
Caused by dense, waterlogged soil. Use a chunky aroid mix, ensure drainage, and repot into fresh mix if roots turn brown and mushy.
