Philodendron subhastatum problems — and how to fix them
Philodendron subhastatum (Philodendron subhastatum) 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.
Faded red undersides
Too little light mutes the maroon colour. Provide brighter indirect light to restore the bicolour contrast.
Yellowing leaves
Overwatering or poor drainage. Let the top third of the mix dry and ensure the pot drains freely.
Leggy growth
Insufficient light or no support. Give bright indirect light and a moss pole to climb for fuller, larger leaves.
Brown leaf tips
Low humidity or salt buildup. Raise humidity above 60% and flush the soil periodically.
