Troubleshooting
Philodendron Insigne problems — and how to fix them
Philodendron Insigne (Philodendron insigne) 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 remain small and undivided
Juvenile growth or low light keeps leaves simple. Provide brighter indirect light and a tall support so foliage matures to its large, lobed form.
Brown leaf margins
Low humidity or salt buildup. Raise humidity, water with filtered or rainwater if tap is hard, and flush the soil periodically.
Root rot and yellowing leaves
From overwatering or a compacted mix. Switch to a chunky aroid blend, ensure good drainage, and let the surface dry before watering.
Thrips and spider mites
Pests target the large, glossy leaves, especially in dry air. Inspect undersides regularly and treat early with neem or insecticidal soap.
