Peace lilies (Spathiphyllum spp.) are among the most beloved indoor plants thanks to their lush green leaves and striking white bracts that resemble delicate flowers. While their foliage alone adds beauty to any room, most plant owners eagerly await the blooms that make peace lilies stand out. The truth is, peace lilies are not heavy bloomers by nature, and sometimes they need a little extra encouragement to show off their white “flags.”
If your peace lily hasn’t been flowering as much as you’d like, don’t worry—it’s not necessarily unhealthy. It simply means the plant’s energy is focused more on growing leaves than producing blooms. With the right care, though, you can shift that balance and enjoy more frequent blossoms.
Below are 10 proven ways to help your peace lily bloom more often.
1. Provide Optimal Light Conditions
Peace lilies thrive in bright, indirect light. While they can survive in low light, blooms are far less likely without adequate illumination. Place your plant near an east- or north-facing window where it will receive gentle sunlight. If natural light is limited, consider using a grow light for 10–12 hours daily. Avoid direct, harsh sun, which can scorch the leaves.
Tip: A peace lily that only grows leaves but refuses to flower is often craving more light.
2. Master the Art of Watering
Peace lilies love consistently moist soil but dislike soggy conditions. Water when the top inch of soil feels dry. Overwatering can suffocate roots, while underwatering causes stress that prevents blooming. Always use a pot with drainage holes to prevent standing water.
Tip: If your peace lily droops slightly, it’s often a gentle reminder that it needs a drink.
3. Maintain Proper Humidity
Native to tropical rainforests, peace lilies thrive in humidity levels of 50% or higher. Dry indoor air, especially in winter, can discourage blooming. Increase humidity by misting the leaves, placing the pot on a pebble tray with water, or running a humidifier nearby.
4. Feed With the Right Fertilizer
For blooms, your peace lily needs extra phosphorus. Use a balanced liquid houseplant fertilizer (10-10-10) or one with a slightly higher middle number (bloom booster). Feed every 4–6 weeks during the growing season (spring and summer), but stop during fall and winter when the plant naturally rests.
Avoid over-fertilizing—it can burn roots and reduce blooming.
5. Repot When Needed
If your peace lily is rootbound, it may struggle to bloom because all its energy is spent surviving. Check if roots are circling the pot or poking through drainage holes. Repot every 1–2 years into a container 1–2 inches larger with fresh, well-draining soil.
Fresh soil also replenishes nutrients that encourage blooms.
6. Prune and Remove Spent Blooms
Once a peace lily bloom fades, trim it at the base of the stem. This redirects the plant’s energy from maintaining old flowers to producing new ones. Regularly removing yellow or damaged leaves also helps the plant stay strong and healthy.
7. Maintain Ideal Temperatures
Peace lilies prefer warmth—between 65°F and 80°F (18°C–27°C). Avoid placing them near cold drafts, heating vents, or fluctuating temperatures. Stress from extreme cold can stunt both growth and blooming.
Keep the Plant Clean
Dusty leaves reduce the plant’s ability to photosynthesize, limiting the energy needed for flowers. Wipe leaves with a damp cloth every few weeks to keep them shiny and dust-free. A healthy, clean plant has more energy to spare for blooming.
Allow for a Resting Period
Peace lilies often bloom in cycles. After a round of flowers, they may pause to regain strength. Don’t panic if your plant isn’t blooming constantly—it’s natural. During rest periods, continue proper care, and soon you’ll see new bracts forming.
10. Be Patient and Consistent
Perhaps the most overlooked secret to getting blooms is patience. Peace lilies are relatively low-maintenance but bloom on their own schedule. Consistency in light, water, humidity, and fertilizer creates the perfect environment. Over time, your plant will reward you with blooms.
Conclusion
Getting your peace lily to bloom more often is less about tricks and more about balance. Think of it as creating the right “mini rainforest” indoors: steady light, proper moisture, warmth, and a little nutrition. With love and consistent care, your peace lily will reward you with those iconic white blooms that brighten any space.
Remember: A happy peace lily doesn’t just bloom more often—it also purifies your indoor air, making your home healthier and fresher.
