How do you care for a peace lily indoors? It’s easier than you think

Caring for your peace lily so it thrives in your home

Peace lilies are a popular houseplant known for their elegant white blooms and dark green leaves. They're said to bring a calming sense to a space, so much so that they’re often given as sympathy gifts.

These plants even have a reputation for helping purify the air. Peace lilies are native to the tropics, which means they prefer warm, humid conditions. Chances are you don’t live in the rainforest, though — so how do you care for a peace lily indoors? It’s easier than you might think!

Benefits to having a peace lily in your home

Sometimes it can seem like every houseplant is the same. Maybe you’ve reached the point where you have a huge collection and you find yourself asking, “Well, what are peace lilies good for?” After all, what’s the point if it’s just another flower?

Growing peace lilies indoors actually comes with a few benefits (besides their beauty):

  1. They purify the air. Peace lilies, like many other plants, can filter out certain pollutants like benzene, carbon monoxide, formaldehyde, and xylene from the air in your home. They’ll help move you toward a cleaner, fresher space.
  2. They can absorb acetone. Although all those chemicals you use help keep your home looking its best, they can leave harmful vapors in the air. Peace lilies can filter out acetone and alcohol particles from things like paints, rubbing alcohol, and varnishes, in addition to other pollutants.
  3. They remove mold spores. Perhaps best of all, peace lilies help eliminate mold spores from your home (which is nice if you live in a particularly damp climate). Mold exposure, especially for those with allergies or asthma, can cause coughing, eye and throat irritation, and sneezing. Having a peace lily in your home may help reduce those effects.

How do you care for a peace lily indoors

Although peace lilies can reach their mature size within three years, they can be quite difficult to get to bloom when grown indoors. Even the happiest, healthiest of potted peace lilies just don’t grow flowers, largely because they’re outside their natural habitat. It’s hard to meet the conditions of a tropical environment when you live in a temperate area, and even harder when you keep the plant indoors.

The best way to help encourage your peace lily to bloom its elegant flowers is to provide consistently ideal conditions. Here's what to do:

Step 1: Keep your peace lily indoors during cool weather.

If desired, you can move them to an outdoor space like a patio or balcony during the summer months; however, they should be brought back indoors before temperatures start to drop. Peace lilies are highly sensitive to cold, and lower temperatures can damage the plant.

Step 2: Place your peace lily where it has room to grow.

Peace lilies grow at a moderate rate, taking at least three years to reach maturity. When you get a new one, you’ll have some time to find the best spot in your home, which should either be one that can accommodate the plant’s mature size or one you can easily move it from when your peace lily needs more room to grow.

Step 3: Keep your peace lily in bright, indirect light, and avoid exposing it to direct light.

Peace lilies prefer bright, filtered light when grown indoors, so you’ll want to place them near a window that gets a decent amount of sun. Take care not to place them directly on the windowsill — they don’t like direct sun, and that amount of light could end up burning the leaves. Just like us, plants don’t like getting sunburnt, either! Keeping your peace lily on a table or plant stand near a south-facing window is ideal.

Step 4: Water when the top inch of the soil is dry.

When in doubt, err on the side of of caution. Under-watering is better than over-watering.

Step 5: Use a rich, loose, well-draining potting soil with lots of organic matter.

Step 6: Keep your plant in a high-humidity environment.

Step 7: Make sure to fertilize your peace lily.

Can peace lilies be propagated?

If you find yourself wanting more than one of these beautiful plants, you can easily propagate them! Peace lilies can be propagated by dividing the offshoots from the parent plant during repotting, which can be done at any time of year (though if you can wait to repot once the growing season has started, the plant will have plenty of time to continue growing strong and establishing roots).

Here's how to remove the offshoot from the parent plant:

Step 1: Gently tug the offshoot away from the parent plant.

Some offshoots will separate with just a little pull, but be careful not to pull too hard and damage them. If they don't separate with a gentle tug, or if you're worried about damaging the plant, move on to step 2!

Step 2: Cut the shoot away from the parent plant using a sterilized knife.

Step 3: Choose a shoot that has at least two leaves and roots of its own.

If it doesn’t, it’s best to let the offshoot grow a bit more before removing it (don’t worry, this won’t harm the parent plant!). You may need to dig carefully at the base of the plant to see if a shoot has roots.

Step 4: Plant the offshoot in a 6-inch pot with fresh soil and water so that it’s moist.

Step 5: Place the freshly potted plant in a similar location to the parent plant, so that it receives the same amount and type of light as it did before.

How long do peace lily blooms last?

More often than not, you'll find peace lilies in bloom at the nursery, although young plants may not have any flowers yet. Peace lily blooms are certainly hardy — they'll definitely last longer than your typical cut flowers. Given the right conditions, you can expect your peace lily flowers to last around one to two months.

After some time, the spathe and spadix flower structure will droop and turn brown, which is totally normal. It's up to you whether or not you want to cut off the spent blooms, but many people do so to keep their plant looking tidy. To encourage future blooms, simply follow the care steps listed above.

Peace lilies are beautiful, calming plants. Although they are a bit particular about their environments, they're still easy enough for even a beginner to grow. It takes patience for a peace lily to bloom, but they're well worth the wait. With the right care and attention, you can keep them alive and happy for many years!

Do indoor plants go dormant during the winter? What you need to know
Your guide to caring for plants during the dormancy season
Person watering a houseplant

Every year, we watch plants outside go dormant. The trees change color, drop their leaves, and we’re left with what appear to be dying forests blanketed in snow. But come spring, without fail, green buds start to pop up all over the place — almost as if the plants have come back to life. But do indoor plants go dormant? Well, yes. Winter dormancy is part of the natural order, and houseplants are no exception.

Houseplants may not go fully dormant, but they’ll most often show signs of winter dormancy as the temperatures start to cool and the days have less light. You’ll be able to tell this is happening when growth starts to slow and your plants begin dropping some leaves. But don’t worry! They’re still alive, storing their energy and needing a bit of love and care.

Many people use fertilizers to make up for poor soil or give plants a boost right before blooming or fruiting. Using fertilizers in outdoor gardens can be fairly simple, but what about indoor plants? You can usually use the same fertilizers for both indoor and outdoor gardens, but that doesn't mean using them in the same way.

Indoor plants have less soil, so you might wonder if they need a different amount of fertilizer or a different fertilizer schedule. How often should you fertilize indoor plants? We have answers.
