Peace Lily Leaf Spots: Care Issues, Not Just Disease

Peace lily has leaf spots on tips and edges; owner wants to identify type. Expert: peace lilies (Spathiphyllum) get few insects (aphids, spider mites, mealybugs). Diseases (root rot, leaf spot, bacterial soft rot) usually from improper care. Key care: even moisture, good drainage, drain holes. Water weekly typically; less in low light/cool temps; more in bright/warm/growth. Test soil with finger—moist = don’t water. High humidity helps. Hydroponics works. Chlorine-sensitive—let tap water sit or use distilled. Overwater → yellow leaves; underwater → wilt + yellow/brown edges.

Diagnosis Shortcut

• Fix care first—most “diseases” disappear.
• If spots persist, fungicide or repot.
• But 90% are cultural.
