Why Is My Peace Lily Turning Brown?

If your peace lily flowers are starting to transition to an unappealing brown color, don’t get too down on yourself — it’s actually a pretty common occurrence.

There are a number of reasons and factors that could be contributing to the browning of your pretty peace lily. 

While the leaves of a peace lily can turn brown as well, the cause behind the color change isn’t always for the same reasons as the color change in a peace lily’s flowers. 

Keep reading to discover the most common reasons that your peace lily’s flowers are turning brown. 

#1: It’s Over-Stressed

You might be stressing your peace lily out if:

  • You are repotting it too often
  • You aren’t following suggested watering increments and amounts
  • The soil isn’t great quality
  • It’s not getting enough light
  • It’s not getting enough nutrients

#3: It’s Aging

Are you doing everything right to care for your houseplant and that brownish hue is still creeping in?

It’s possible that may just be a natural part of the aging process, since a peace lily flower doesn’t stay the same color over its lifespan.

In the natural life cycle of the peace lily, the flower:

  1. Starts green
  2. Turns white; and 
  3. Eventually browns as it ages 

So, a brown flower doesn’t always indicate a problem. However, by the time a flower is browning, this means it’s close to dying. It will likely wither soon and possibly fall off.

How Long Can You Expect Your Peace Lily to Live?

Peace lilies can survive, on average, anywhere from three to five years.

Their flowers, once bloomed, on the other hand, only last about 10 days before they brown and likely fall off. 

Be sure not to toss out your peace lily just because its flowers have died; you likely have more years of beauty to enjoy. 

Can You Prolong the Life of Your Peace Lily?

As much as we wish our peace lilies could live forever, they all die eventually.

The good news is that by following the care tips below, you can help extend the flower’s life by a month or two.

5 Care Tips to Keep Your Peace Lily Happy and Healthy

While some houseplants are “set and forget” plants, there are others that require a fair amount of maintenance and attention from you, including the peace lily.

We review their growing requirements to keep in mind to make sure your plant stays happy and healthy.

#1: Watering

You can choose to pot your peace lily in soil or in water; but either way, you should avoid using tap water on them.

Because of chemicals like fluoride found in tap water, leaf browning can occur more frequently, especially at the tips. 

To keep your peace lily’s leaves and flowers happy, only use filtered water. Room temperature water filtered water is even better. 

If you have your peace lily potted in soil, you’ll want to water consistently but not too much. Keep an eye on the soil; if it has dried out, this is a sign that it’s time for fresh water. 

Leaving your plant with dry soil for too long or over watering can cause leaf browning or even blackening.

#2: Sunlight

Dappled light is best for a peace lily, so be sure to keep yours out of direct sunlight.

In nature, dappled light is basically spotted light or sunlight that’s filtered through other trees, plants, or leaves. You can create dappled light in your home by placing solid or transparent objects between the sun and your peace lily (window shades or drapes would work).

Our advice? Position your peace lily towards a window facing east. Situating them here will allow them some sun but not too much.

#3: Temperature

The ideal temperature for a peace lily is 70 degrees Fahrenheit or higher. 

Be careful of seasonal or winter drafts – if the temperature drops below 60 degrees, it will be too cold for your plant to thrive. 

On top of a warmer temperature, peace lilies also require humidity. You can opt to:

  1. Use a humidifier
  2. Fill a tray with gravel and water and place your potted plant on top of the tray; or 
  3. Mist your peace lily

#4: Fertilizer

It’s okay to want to give your peace lily all the nutrients it needs, but you do want to avoid fertilizing too often. 

To encourage the flowers to blossom, fertilize your peace lily on a six-week basis starting at the end of winter. 

You’ll also want to be careful of the amount of fertilizer you give your plant.

It’s best to avoid giving your peace lily a full dosage of food. Instead, we suggest keeping the dosage to half of what is recommended. 

#5: Gibberellic Acid

Gibberellic acid is a plant growth hormone that is often used to treat young peace lilies to bloom a long time before they have fully matured. 

If you use gibberellic acid, it’s best to start with very little. Even a small dab of gibberellic acid can encourage your peace lily to grow its flowers.

However, we recommend skipping this practice and leaving it to skilled growers.

Should I Throw Out My Peace Lily Once the Flower Is Dead?

Most likely not! Unless you’ve had your peace lily for a few years (remember, their lifespan, on average, can range anywhere between three to five years), a dead flower doesn’t relate to the life of the peace lily itself. 

The plant should last several years, but dead flowers need to be pruned at the base along with any dead leaves on the plant.

Why Are My Peace Lily Leaves Turning Brown?

As we shared earlier, peace lilies prefer medium, indirect sunlight. If they’re exposed to too much direct sunlight or even too little, they will often develop yellow leaves.

Overwatering or under-watering can also commonly cause leaves to wilt and turn yellow or brown around the edges. 

It’s also good practice to make sure that the pot holding your peace lily has a drainage hole to ensure water can drain properly. 

My Peace Lily Won’t Flower At All, What Am I Doing Wrong?

Peace lilies can be finicky plants, so following the care instructions will go a long way. 

Sunlight and watering are particularly important to the healthy flowering of the plant. Ensure that environmental factors aren’t contributing to your peace lilies lack of blooms.
