The peace lily is one of the most popular houseplants—and for good reason. The plant can tolerate a decent amount of neglect, making it a good choice for beginner (or simply forgetful) plant owners. It’s also a common choice for a houseplant gift, symbolizing peace, hope, comfort, and sympathy. Perhaps the most compelling reason to own or gift a peace lily plant, however, is that it blooms striking white flowers. So, if you have a peace lily that just won’t bloom, you’re probably feeling pretty disappointed—and wondering why. We asked plant experts for their insight on the reasons why peace lily plants might not bloom and tips on how to fix it.

Reasons Your Peace Lily Isn’t Blooming

In the right conditions, peace lilies can bloom year round, with each bloom lasting one to two months. However, just because your peace lily isn’t blooming, that doesn’t necessarily mean something’s wrong. “Some peace lilies naturally bloom less than others,” says professional gardener Chad Massura. “If your plant is happy but just not blooming, it might need a little extra push to get there.” So, don’t panic if you haven’t seen a white flower pop out of your peace lily for a while—but here are some potential reasons that can help you get to the root of the issue.

Your Plant Isn’t Getting Enough Light

“Not enough light is hands-down the most common reason we see peace lilies refuse to bloom indoors,” horticulturist Justin Hancock says. While peace lilies have earned a reputation for tolerating low light levels, he says the plant still needs a decent amount of consistent light to thrive and bloom.

“If your peace lily is thriving with lush green leaves but no blooms, it’s likely not getting the right ‘signals’ that it’s time for your plant to flower,” Massura says. “The most common reason is not enough light—peace lilies can survive in low light, but they need bright, indirect light to be able to bloom.”

Your Plant Is Rootbound

If your peace lily won’t bloom, be sure to check the bottom of its pot. Hancock says a peace lily that’s rootbound probably won’t bloom well.

Your Plant Is Cold

Just as frigid office temperatures might prevent you from being productive and happy, cold environments can also prevent your peace lily from producing blooms. If your plant is kept in temperatures below 50 degrees Fahrenheit, Hancock says that can prevent it from flowering.

Your Plant Isn’t Getting Watered Consistently

Consistent watering is another important factor in keeping your peace lily happy and healthy enough to produce blooms. “If [your peace lily] isn’t watered consistently, that stress may also inhibit flowering,” Hancock says.

Not Enough Fertilizer

While not as common as the above reasons, Hancock says, soil with low fertility can also be a reason that your peace lily isn’t flowering. “Happily, fertilizing periodically in spring and/or summer can be an easy way to prevent it,” he adds.

Your Plant Is Too Old (or Too Young)

While we may not think of our plants as aging, they do—and age can actually play a role in whether or not your peace lily flowers. For starters, peace lily plants may not bloom until the plant is mature enough, which could take one to three years.

On the other end, a peace lily might be too old to bloom. Your plant might reach an age where it’s still producing new roots and leaves, but will no longer send up new flowers.

How to Get a Peace Lily to Bloom

To get your peace lily to bloom again (or for the first time) it’s important to keep conditions consistent and comfortable for your plant. For starters, Hancock says, you should make sure your peace lily is in a good spot where it’s getting a good amount of light (Massura recommends at least 10 to 12 hours of light per day), keep it in average household temperatures and average to above average humidity levels. All of this plus consistent watering, “and a little fertilizer once or twice a year should be the basics to set you up for successful blooms,” Hancock says.

After all these steps, if your plant still won’t bloom, Massura recommends trying a mild “stress reset,” which involves slightly reducing watering for a few weeks, then resuming normal care.

And if you want your plant to grow faster and produce bigger blooms, Hancock adds that it’s important to repot your plant regularly. “Smaller pot sizes can restrict growth,” he says.
