Troubleshooting
Mauna Loa Peace Lily problems — and how to fix them
Mauna Loa Peace Lily (Spathiphyllum 'Mauna Loa') 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.
Brown leaf tips
Most commonly caused by low humidity, fluoride in tap water, or over-fertilising. Switch to filtered or rainwater, increase humidity, and flush the soil every few months to remove salt build-up.
Failure to bloom
Insufficient light is the primary cause. Move to a brighter spot out of direct sun. Plants also need a brief cooler rest period in autumn (around 16°C) to trigger the next flush of flowers.
Yellow leaves
Overwatering leading to root rot is the most likely culprit. Check the roots — healthy roots are white and firm; rotten roots are brown and mushy. Let the soil dry slightly more between waterings and ensure pots have adequate drainage.
