Troubleshooting
Canna-Leaved Peace Lily problems — and how to fix them
Canna-Leaved Peace Lily (Spathiphyllum cannifolium) 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 often caused by fluoride in tap water or low humidity. Switch to rainwater or filtered water and raise ambient humidity.
No blooms
Usually caused by insufficient light. Move to a brighter location with indirect light and ensure the plant is not over-fed with nitrogen, which promotes leafy growth at the expense of flowers.
Root rot
Caused by consistently wet, poorly aerated soil. Repot into a fresh, well-draining mix and adjust watering frequency.
Pale or yellowing leaves
May signal nutrient deficiency or overwatering. Resume a regular feeding schedule in spring and check drainage.
Spider mites
Can attack in low-humidity conditions. Increase humidity and treat with insecticidal soap spray, covering leaf undersides thoroughly.
