Problem: Some peace lilies need a brief “rest” period between bloom cycles to store energy. Constant warmth and moisture year-round may disrupt this natural rhythm.
Solution: In winter or after a bloom cycle:
Slightly reduce watering
Move to a cooler spot with indirect light
Stop fertilizing for 4–6 weeks
This rest period mimics nature and helps trigger another bloom cycle in early spring.
9. Old or Spent Flowers Not Removed
Problem: Leaving spent blooms on the plant can divert energy away from producing new flowers. Dead flowers may also develop mold or sap-sucking pests.
Solution: Deadhead blooms as soon as they begin to fade or turn green. Cut the flower stalk at the base using clean, sharp scissors.
This redirects energy to root and leaf development, supporting the next bloom.
10. Growing a Non-Flowering Hybrid
Problem: Some peace lilies sold commercially – especially compact varieties – are bred for foliage, not flowers. These cultivars may rarely bloom indoors.
Solution: Check the variety:
Standard Spathiphyllum wallisii varieties are most likely to bloom.
Dwarf or miniature hybrids may require near-perfect conditions to flower.
Ask your supplier or nursery about the cultivar. If it hasn’t flowered in years despite good care, consider replacing it with a more bloom-friendly variety.
How to Encourage a Peace Lily to Bloom Again
If you’ve corrected the issues above, your peace lily is likely to bounce back within a few weeks to months.
For even more success, follow these proven bloom-boosting techniques:
1. Provide Consistent Indirect Light
Keep it near a bright window with filtered sun. A peace lily grown in a dark corner will struggle to flower.
2. Feed Monthly in Spring and Summer
Switch to a bloom-promoting fertilizer (higher phosphorus) during the growing season.
3. Increase Humidity
Place the plant near a humidifier or on a pebble tray to mimic its natural environment.
4. Water Properly
Keep soil evenly moist, never soggy or bone dry. Avoid fluoride-heavy tap water if possible – peace lilies are sensitive.
5. Repot Every 1–2 Years
Use fresh soil and a slightly larger pot to give roots more space and nutrients.
Frequently Asked Questions
How long do peace lily flowers last?
Each bloom typically lasts 4–6 weeks. The spathe gradually turns green, then brown, at which point it should be removed.
Should I use distilled water for my peace lily?
Peace lilies are sensitive to fluoride, chlorine, and salts in tap water, which may cause brown tips. Use distilled, rainwater, or filtered water if possible.
Why is my peace lily producing leaves but no flowers?
This is usually due to:
Low light
Lack of fertilizer
Incorrect pot size
Low humidity
Aging plant needing division
Addressing these will help redirect energy toward flowering.
Can peace lilies bloom year-round?
While some indoor peace lilies bloom multiple times a year, most follow a seasonal pattern and bloom mainly in spring and summer when light and warmth increase.
A peace lily that won’t flower is often sending a signal that something in its care routine needs attention. Fortunately, most of the reasons are easy to fix with minor adjustments.
By avoiding these 10 common mistakes – especially low light, inconsistent watering, and lack of nutrients – you’ll create the ideal environment for your peace lily to thrive and bloom.
