Encouraging Blooms on a Mature Peace Lily

Why No Flowers?

Peace Lilies (Spathiphyllum) bloom sporadically. Varieties differ—some bloom once a year, others more. Greenhouse plants are forced to bloom heavily; home conditions rarely match.

Flowering Checklist

1. Light: Bright indirect. North/east windowsill, uncovered all day.
2. Potbound: They bloom best when roots fill the pot. Do not repot.
3. Water: Thoroughly when surface feels barely dry. They wilt dramatically but recover in 2–4 hours. Avoid wilting.
4. Fertilizer: Half-strength monthly during active growth.
5. Variety: Some cultivars simply bloom less.

Bottom Watering?

Irrelevant to blooming. Top-watering correctly is fine.

Your plant is healthy and green—focus on light and potbound status for flowers.
