Calm, tropical, beautiful. Sounds good, right? You can take a big step toward bringing that sort of ambiance to your favorite room by growing peace lilies. The name "peace lily" came about because the white flowers look like white flags of peace—though they aren't actually lilies.They're tropical aroids, and when you practice good peace lily care, these plants can live for years and flower over and over again. Ideal for home or office growing, they're easy to take care of, don't require a lot of light, and do a wonderful job removing dust and mold particles from the air. Standing 1 to 4 feet tall, peace lilies are also quite striking, with dark green leaves creating a gorgeous contrast to the white flowers.

Where to Grow Peace Lilies

Peace lilies will practically grow in the closet, but that doesn't mean that's where you should put them. When grown in low light, these plants will rarely bloom. So if it's foliage you're after, go ahead and put your peace lily in a dark corner. If you want flowers, place it where it will receive bright, indirect light. Just make sure there aren't any drafts—since they're tropical, peace lilies are sensitive to cold temperatures.

One word of caution: Peace lily leaves contain a compound that can cause swelling of the tongue or even vomiting when eaten, so keep your plant away from kids and pets.

How to Repot Peace Lilies

While peace lilies are perfectly content growing in containers, they don’t like being in pots much larger than their root balls. They are actually quite happy to be a bit crowded in their pots. You’ll know it’s time to repot when your plant begins to wilt more frequently. At that point, its roots will have begun to take up so much of the container that there’s little soil left to hold water. Repot your peace lily using Miracle-Gro® Indoor Potting Mix, which contains no compost or bark, both of which are known to shelter pesky fungus gnats.

Select a container that has good drainage and is no more than 1-2 inches larger in diameter than the root ball of your peace lily.
Fill the container about ⅓ full with Miracle-Gro® Indoor Potting Mix.
Gently remove your peace lily from its current pot and place the plant in the container so that the top of the root ball is about an inch below the top of the rim. This leaves room for watering.
Fill in around the root ball with more potting mix.
Water your peace lily until moisture begins to drain out the bottom of the pot, then put a plant saucer under it and move it to its new home.

How to Water Peace Lilies

Peace lilies need consistently moist soil, but they definitely don’t like to sit in saturated soil. Whenever the top inch of soil is dry, water the plant until the overflow starts to come out of the drainage holes. Thirty minutes after watering, dump any water that remains in the plant saucer.

Peace lilies don’t usually behave like drama queens—unless you forget to water them. One day your beloved plant is looking gorgeous, then the very next day you find it flopping over in its pot like an exhausted teenager on a sofa. Not to worry! Simply water immediately, let the plant soak it up, and water again. That’s it—you’re back on track.

How to Feed Peace Lilies

As your peace lily grows, it'll crave additional nutrients. Give it Miracle-Gro® Indoor Plant Food, which is designed to feed indoor plants instantly. Be sure to follow label directions!

How to Divide Peace Lilies

Your peace lily will eventually fill their entire container with roots, and when that happens, it’s time to move it to a bigger pot or divide it. Remove your plant from the pot and pull it apart (don’t be shy!). Replant sections in pots that are only ⅓ larger than the root clump, using the planting directions above. Give some to your pals, or spread them out through the darker corners of your home.

Troubleshooting Problems with Peace Lilies

Peace lily care tends to be pretty straightforward, but you might notice a few issues with these plants (in addition to the wilting mentioned above). Keep any eye out for:

Fungus gnats. As mentioned above, if you grow peace lilies in Miracle-Gro® Indoor Potting Mix, this is less likely to be an issue. But if you’re growing in a different type of potting soil, you may need to fight this battle. Fungus gnats are attracted to damp soil, so try watering less frequently and make sure the top of the soil dries out between waterings. You can also use sticky traps to catch the flying adults.
Yellow leaves. Older leaves on peace lilies will turn yellow with age. Remove them, cutting all the way at the center of the plant. Plants that have been overwatered will sometimes develop yellow leaves, too. Let the soil dry out a bit and cut back on watering, and the plant may recover.
Brown edges. This is usually a sign that your peace lily has been getting direct sunlight. If that’s the case, move the plant out of sunbeams. You can also try elevating the humidity around your plant. Fill the saucer that goes under the pot with small pebbles. Add water, up to just below the top of the stones. The water will evaporate up around the leaves, raising the humidity.
Zero blooms. If your peace lily isn’t blooming, move it to an area where it will get more bright (but not direct) light.
Dusty leaves. Peace lily leaves are large and tend to collect dust. You can put the whole plant in the shower and hose it down. Let the plant leaves dry and apply Miracle-Gro® Leaf Shine for shiny leaves—beautiful!
