Troubleshooting
Philodendron Mexicanum problems — and how to fix them
Philodendron Mexicanum (Philodendron mexicanum) 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.
Small leaves without a support
Left unsupported it produces smaller juvenile leaves. Give it a moss pole and bright light to develop large, mature arrow-shaped foliage.
Yellowing leaves
Usually overwatering. Allow the top of the mix to dry between waterings and ensure the pot has free drainage.
Faded leaf colour
Insufficient light dulls the bronze undersides and red petioles. Move to brighter indirect light to intensify the colouring.
Brown leaf tips
Low humidity or salt buildup. Raise humidity and periodically flush the soil with plain water to clear fertiliser salts.
