Peace lilies (Spathiphyllum spp.) are famous for their beautiful, glossy green leaves and lovely, elegant white flowers. Because of this, they are incredibly popular among houseplant lovers.
In fact, peace lilies are generally an easy houseplant to care for; however, they do sometimes become a bit tricky to get to flower regularly. Mine rarely flowers, but when it does, I feel like I have accomplished something! I feel like the plant is telling me, “You’re doing alright, you are not killing us.”
I am always on the lookout for some even better tips for care. In this article, I will provide some tricks and tips for getting your peace lily to produce more flowers, as well as some care and maintenance recommendations to help the overall plant health so you can benefit from all the beauty of blooms!
💡 1. Light Them Up: Find the "Goldilocks" Zone
Peace lilies thrive in bright, indirect light. The best location for your peace lily is next to an east- or north-facing window, or in a spot that receives filtered light through a sheer curtain.
While they are famous for surviving in low-light offices, low light is the number one reason a peace lily refuses to bloom. They need energy to produce flowers, and they can't get that energy in the dark.
💡 Pro Tip: If your plant is in a dark corner, slowly move it a few feet closer to a window every week. Sudden changes in light can shock the plant. When watering, it is important not to let them sit in saturated water, so be sure the pot has drainage holes so excess water can escape. Peace lilies love light, and this is important for flowering, so be sure they are getting enough!
🪴 2. The Secret to Blooms: Let Them Get "Root-Bound"
2. The Secret to Blooms: Let Them Get "Root-Bound"
This is the most counter-intuitive tip for new plant parents: Peace lilies actually prefer to be slightly root-bound.
If you plant a small peace lily in a massive pot, it will focus all its energy on growing roots to fill that space. It won't even think about flowering until its roots have completely filled the container.
How to Know if It's Time to Repot:
✅ The roots are visibly growing out of the drainage holes.
✅ The plant is drinking water so fast the soil dries out in a day or two.
✅ The root ball is so dense you can barely see soil when you lift it out.
🌿 The Rule of Thumb: When you do repot, only go up one pot size (about 1-2 inches wider in diameter). Give it just enough room to breathe, but not enough to sprawl.
🧪 3. Feed for Blooms: The Right Fertilizer
If your peace lily has plenty of light and a cozy pot, but still won't bloom, it might be missing the right nutrients.
Many general-purpose plant fertilizers are high in **Nitrogen **(N), which promotes lush, green leafy growth. But to get flowers, your plant needs **Phosphorus **(P).
Nutrient
What It Does
Best For
**Nitrogen **(N)
Fuels leaf and stem growth
Foliage plants, or peace lilies that aren't blooming
**Phosphorus **(P)
Stimulates root development and flower/fruit production
Blooming houseplants, peace lilies ready to flower
**Potassium **(K)
Supports overall plant health and disease resistance
All plants, general vitality
How to feed: Use a balanced, water-soluble houseplant fertilizer (like a 20-20-20) or a specific bloom-booster (like an orchid or African violet fertilizer) diluted to half-strength. Feed it once a month during the spring and summer (the active growing season). Stop fertilizing in the fall and winter.
💧 4. Master the "Drama" of Watering
Peace lilies are famously dramatic. When they are thirsty, they will flop over dramatically, looking completely dead. But give them a good drink, and they will perk right back up in a few hours.
While this makes it easy to know when they need water, you shouldn't let them get to the "drama" stage too often. Repeatedly letting the plant wilt to the point of collapse stresses the roots and can cause the tips of the leaves to turn brown and die.
The Perfect Watering Routine:
✅ Check the soil: Stick your finger an inch into the soil. If it feels dry, it's time to water.
✅ Water thoroughly: Pour water until it runs out the drainage holes.
✅ Empty the saucer: Never let the plant sit in a puddle of water, or the roots will rot.
✅ Use filtered or distilled water: Peace lilies are highly sensitive to chlorine and fluoride in tap water, which causes brown leaf tips. Let tap water sit out overnight before using it to allow the chlorine to evaporate.
🌡️ 5. Mimic Their Tropical Origins
Peace lilies are native to the tropical rainforests of Central and South America. To get them to flower, try to recreate their natural habitat.
Temperature: Keep them in a room between **65°F and 80°F **(18°C - 27°C). Keep them away from cold drafts, air conditioning vents, and radiators.
Humidity: They love moisture in the air. If your home is dry (especially in winter), place the pot on a pebble tray filled with water, group it with other plants, or run a humidifier nearby.
✂️ 6. Deadheading: Redirecting the Plant's Energy
When a peace lily flower finishes its lifecycle, the white "petal" (which is actually a modified leaf called a spathe) will turn green, and eventually brown.
Do not just leave it there.
If the plant is spending energy trying to produce seeds on an old, fading flower, it won't have the energy to push out new ones.
How to Deadhead:
Wait until the white spathe has turned completely green and starts to look slightly brown or papery at the edges.
Take a pair of clean, sharp scissors or pruning shears.
Follow the flower stem all the way down to the base of the plant, near the soil line.
Snip the stem off cleanly at the base.
🌱 Bonus grooming: While you're at it, snip off any yellow or brown leaves at the base, too. This keeps the plant looking beautiful and directs all its energy toward new growth and new blooms.
❓ Frequently Asked Questions
Q: Why did my beautiful white flower turn green?
A: This is completely normal! The white part of the flower is a spathe (a modified leaf). As it ages, it naturally produces chlorophyll and turns green. After it turns green, it will eventually turn brown. Cut it off at the base to encourage new blooms.
Q: Are peace lilies toxic to pets?
A: Yes. Peace lilies contain calcium oxalate crystals. If chewed or ingested by cats or dogs, it can cause severe irritation of the mouth, tongue, and lips, excessive drooling, vomiting, and difficulty swallowing. Keep them out of reach of curious pets. (Note: They are mildly toxic to humans, too, but usually just cause skin irritation or an upset stomach if ingested).
Q: How long do peace lily flowers actually last?
A: A healthy peace lily bloom can last anywhere from one to two months. After that, it will naturally begin to turn green and fade.
Q: Can I put my peace lily outside in the summer?
A: Yes, but be very careful! Place it in a deeply shaded, protected area (like a covered porch). Direct outdoor sunlight will scorch the leaves in minutes, and bringing it back inside might introduce pests.
Q: My plant has lots of leaves but zero flowers. What am I doing wrong?
A: It’s almost certainly one of three things: 1) It's not getting enough bright, indirect light. 2) It's in a pot that is too large. 3) You are giving it too much nitrogen-heavy fertilizer. Adjust these three factors, and you should see a bloom in the next growing season!
💙 A Compassionate Closing Thought
If you are reading this because you are staring at a lush, green, beautiful peace lily that simply refuses to give you a single white flower—please know:
🌿 Your plant is not broken. It is just communicating its needs in the only way it knows how. A lack of flowers doesn't mean you are a bad plant parent; it just means the environment needs a tiny tweak.
🌿 Growth takes time. Nature doesn't operate on our schedules. Your peace lily is growing roots, building strength, and waiting for the exact right moment to share its beauty with you.
🌿 You are doing a good job. The fact that you are researching, learning, and caring enough to ask "how can I help you bloom?" shows how much love you put into your home.
🌿 Enjoy the green. Even when it isn't blooming, your peace lily is purifying your air, softening your space, and bringing life into your room. That is a miracle all on its own.
That moment when a new, pale green nub finally pushes its way up from the soil and unfurls into a brilliant white flower?
It feels like a gift.
It feels like a quiet "thank you" from a living thing you've nurtured.
So adjust the light, check the pot size, and give it a little fertilizer. And then, be patient.
Your peace lily knows you care. And when it's ready, it will bloom.
