Growing Peace Lilies in Water: Bloom Expectations

Peace lilies (Spathiphyllum) are less likely to bloom when grown hydroponically than in soil. Many modern hybrids flower poorly regardless of medium. If you keep yours in water, use a hydroponic fertilizer solution or a complete fertilizer with trace elements at a very dilute rate.

For better flowering, pot the plant in a well‑draining mix, provide bright indirect light, and keep the soil evenly moist.
