Troubleshooting
Sensation Peace Lily problems — and how to fix them
Sensation Peace Lily (Spathiphyllum 'Sensation') 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 and edges
Very common on large-leaved cultivars and typically caused by low humidity, fluoride toxicity from tap water, or salt accumulation from over-feeding. Switch to rainwater or filtered water, flush the soil periodically, and increase ambient humidity.
Toppling or instability
The large top-heavy canopy can tip lightweight plastic pots. Use a heavy terracotta or ceramic pot with a wide base, and ensure the compost is suitably firm. Staking is rarely needed if the pot-to-plant ratio is correct.
Mealybugs
White cottony masses in leaf axils and along stems indicate mealybugs. Remove visible colonies with a cotton bud dipped in rubbing alcohol, then spray the whole plant with insecticidal soap or neem solution. Repeat every 7–10 days until clear.
