Peace Lily Not Flowering? How to Get It to Bloom Again

Most peace lilies stop flowering because they get too little light. Move yours to bright, indirect light and it will usually bloom again within a few months.

Age, season and feeding matter too. A young plant, or one fed a high-nitrogen food, may grow plenty of leaves but no flowers.

Many peace lilies bloom heavily at the store, then stop at home. That is usually not your fault.

Growers often treat plants with a plant hormone called gibberellic acid to force flowers for sale. Once it wears off, the plant blooms on its own natural schedule.

The good news is that a healthy peace lily wants to flower. You just need to give it the right conditions.

Quick Checklist: Why Your Peace Lily Is Not Blooming

Reason	How to tell	Fix
Too little light	Dark green, healthy leaves but no flowers	Move to bright, indirect light
Too young	Plant is under about a year old	Wait; give good light and care
Wrong season	It is fall or winter	Expect blooms in spring and early summer
Too much nitrogen	Lots of lush leaves, no flowers	Switch to a balanced or bloom food
Pot too big	Roots have lots of loose soil around them	Keep it slightly snug when repotting
Stress	Drooping, yellowing or root problems	Fix watering and temperature first

What Helps a Peace Lily Bloom

Light is the big one, and a good feeding routine comes second. These three products cover both.

A grow light for dim rooms

If your plant sits more than a few feet from a window, a small full-spectrum grow light can make the difference. Run it 10 to 12 hours a day.

A balanced indoor plant food

Feed every 6 to 8 weeks in spring and summer at half the label strength. Peace lilies are light feeders, and too much burns the roots.

Check price on Amazon.

A bloom booster, used sparingly

A high-phosphorus bloom food can nudge a mature plant into flowering. Use it at a quarter strength, once or twice in late winter or spring.

Too Little Light: The Main Reason

Peace lilies survive in low light, which is why they are sold as “low-light plants.” But surviving is not the same as flowering.

To bloom, they need bright, indirect light. A spot a few feet from an east or north window is ideal.

Avoid hot direct sun, which scorches the leaves. A sheer curtain works well on a south or west window.

If your home is dark, see plants that do better in dark rooms, or add a grow light.

Age and Season

Young peace lilies focus on growing roots and leaves. Most need to be around a year old before they bloom on their own.

Mature plants usually flower in spring and early summer. Some bloom again in fall, but a quiet winter is normal.

Feeding: Less Nitrogen, a Little More Phosphorus

All-purpose foods high in nitrogen push leafy growth. That can mean a lush plant with no flowers.

Use a balanced food at half strength, and stop feeding in late fall and winter. For more on routines, read how often to fertilize indoor plants.

Watch for crispy brown leaf tips. They are a sign of too much fertilizer, so flush the soil with plain water if you see them.

Pot Size and Repotting

A peace lily that is slightly root-bound often blooms better. Moving it to a much larger pot sends its energy into roots instead.

When you repot, choose a pot just 1 to 2 inches wider. The best time is spring, after flowering.

Stress From Watering or Temperature

A plant that keeps wilting, or sits in cold drafts, will not waste energy on flowers.

Fix the basics first. If your plant keeps flopping, see why a peace lily droops. If the leaves are yellowing, read why peace lily leaves turn yellow.

Is It Normal for Peace Lily Flowers to Turn Green?

Yes. The white “petal” is really a leaf-like spathe, and it naturally fades to green as the flower ages.

Once it turns green or brown, cut the flower stalk off at the base. This keeps the plant tidy and saves its energy for new growth.

A Simple Plan to Get New Blooms

• Late winter: Move the plant to a brighter spot, or add a grow light.
• Early spring: Start feeding at half strength every 6 to 8 weeks. Repot only if badly root-bound.
• Spring to early summer: Keep watering steady and look for new flower stalks rising from the base.
• After blooming: Cut spent flowers at the base and keep up the same care.

Most mature plants respond within 2 to 4 months of better light.

A Note on Pets

Peace lilies contain calcium oxalate crystals. According to the ASPCA, they are toxic to cats and dogs if chewed. Keep them out of reach.
