Peace lilies (Spathiphyllum spp.) are among the most beloved indoor plants for good reason – their lush green foliage and striking white blooms add elegance to any room, while their ability to thrive in low light makes them a top choice for beginners and seasoned plant lovers alike.
But if you’ve owned a peace lily for more than a few months, you may have noticed something frustrating: those gorgeous blooms don’t last forever, and sometimes, they’re slow to return.
The good news? With the right care – and one powerful blooming trick – you can encourage your peace lily to produce more flowers, more often, and even keep it blooming almost year-round.
Understanding the Peace Lily’s Blooming Cycle
Before we jump into solutions, it’s important to know how peace lilies bloom naturally.
Peace lilies are tropical plants native to the rainforest floors of Central and South America.
In their natural environment, they bloom seasonally – typically during spring and early summer – when light, temperature, and humidity are optimal.
The white “flowers” you see aren’t technically petals, but spathes, a modified leaf that surrounds the plant’s small, spike-like cluster of flowers (the spadix).
Blooming Facts:
Typical bloom period: Spring to early summer
Each bloom can last 6–8 weeks
After blooming, the plant rests before sending up new flowers
Indoor plants may bloom twice a year – but with the right care, this can be increased
Why Your Peace Lily Isn’t Blooming
If your peace lily has stopped producing flowers for months, one or more of these factors could be the cause:
Insufficient Light – Peace lilies can survive in low light, but they need bright, indirect light to produce blooms. Without enough light, they focus on growing leaves instead of flowers.
Overwatering or Underwatering – Both extremes cause stress, which diverts energy away from flowering.
Nutrient Deficiency – If the soil lacks phosphorus – the nutrient responsible for flower production – your plant will produce foliage but few blooms.
Incorrect Temperature – Peace lilies prefer temperatures between 65–80°F (18–27°C). Consistent exposure to cold drafts or excessive heat can delay blooming.
Age of the Plant – Young plants may take time to mature before producing their first flowers.
How to Get Peace Lilies to Bloom More Often
1. Ensure Bright, Indirect Light
While peace lilies tolerate low light, they won’t bloom without sufficient brightness. Their natural environment offers bright but filtered light – think sunlight filtered through jungle foliage.
What to Do:
Place your plant near an east- or north-facing window.
Avoid direct sun, which can scorch the leaves.
If your home has limited natural light, supplement with a full-spectrum grow light for 6–8 hours per day.
Pro Tip: Watch your plant’s leaves – if they’re dark green but no blooms appear, it may need more light.
2. Water Correctly and Maintain Moisture Balance
Peace lilies are sensitive to both drought and overwatering. Either extreme can disrupt blooming.
What to Do:
Water when the top 1–2 inches of soil feel dry.
Use a pot with drainage holes to prevent soggy soil.
Water deeply, allowing excess to drain out.
Humidity Tip: Peace lilies love humidity. Misting, grouping with other plants, or using a pebble tray can boost moisture levels around the plant.
3. Feed Regularly With a Balanced Fertilizer
In nature, peace lilies benefit from nutrient-rich leaf litter. Indoors, they need supplemental feeding to thrive and bloom.
What to Do:
Use a balanced fertilizer (like 20-20-20) diluted to half strength.
Feed every 6–8 weeks during spring and summer.
Pause feeding during fall and winter when growth slows.
Watch Out: Avoid over-fertilizing – salt buildup can harm roots. If you see brown leaf tips, flush the soil with water to wash out excess minerals.
4. Keep Temperatures Warm and Stable
Temperature plays a crucial role in triggering blooming. Sudden drops in temperature can halt flower production.
What to Do:
Maintain a consistent room temperature between 65–80°F (18–27°C).
Avoid drafts, radiators, or cold window sills.
Tip: Use a thermometer in colder months to ensure nighttime temperatures don’t drop below 55°F (13°C).
5. Prune Regularly to Stimulate Growth
