Peace lilies are not just any indoor plant—they adapt well to interior spaces, often flourishing in low light. They’re known for their broad, shiny leaves and occasional white blooms that resemble a hooded flag, adding visual interest year-round. Whether placed on a shelf, windowsill, or floor, this plant requires very little to make a big impression.

How to Grow a Peace Lily

Growing a peace lily indoors is surprisingly easy, making it a favorite for anyone looking to add a low-effort, high-impact plant to their home. With just a bit of attention to light, water, and repotting needs, this tropical beauty will reward you with lush leaves and elegant white blooms.

Peace Lily Light Requirements

In its native rainforest environment, this plant grows under the canopy where sunlight is filtered through the trees. That means the peace lily is well adapted to indoor conditions with indirect light. The best spot for your plant is near a bright window with filtered sunlight—never in direct sun, which can scorch its leaves.

Peace lilies can tolerate low light, but they may not flower as often in dim conditions. In brighter, indirect light, you’re more likely to see those iconic white spathes that resemble flowers. If you’re mainly keeping your plant for its foliage, lower light is fine, but for frequent blooming, brighter conditions are ideal.

Watering Peace Lily Plants

A peace lily prefers soil that stays slightly moist but never soggy. Overwatering is a common mistake with this plant and can lead to root rot. It’s best to check the soil regularly—stick your finger into the top inch, and only water when it feels dry. If it’s still damp, give it more time.

This plant is surprisingly forgiving and can handle occasional neglect. Some gardeners even wait for it to droop slightly before watering, which doesn’t harm the plant and can help avoid overwatering.

Always ensure the pot has drainage holes, and never let the plant sit in standing water. Consistent moisture with proper drainage is the key to a healthy, thriving peace lily.

Peace Lily Repotting Tips

One of the many reasons a peace lily is such a great houseplant is its tolerance for being root bound. In fact, this plant often performs best when its roots are a bit snug in the pot. But over time, even the most relaxed plant needs a little more room to grow.

Look for these signs that it’s time to repot:

• Roots poking through the drainage holes
• Soil drying out within a few days of watering
• Leaves becoming crowded or slightly deformed

If you notice any of these, it’s probably time to move your plant into a slightly larger container—ideally one that’s about 2 inches wider than the current pot.

The best time to repot is late winter or early spring, just before the plant enters its active growing season. Be gentle with the root system, and refresh the potting mix to support healthy new growth. A freshly repotted plant might pause flowering for a bit, but it will bounce back stronger than ever.

How to Propagate Peace Lilies

If your peace lily is thriving and you’re ready to grow more, propagation is simple—and doesn’t require seeds or complicated steps. The easiest way to propagate this plant is by division, which involves separating the root system into smaller, independent parts.

Here’s how to do it:

1. Remove the entire plant from its pot.
2. Look for natural crowns or clumps—these are the sections where leaves and roots emerge together.
3. Gently pull apart the crowns. If they resist, use a clean, sharp knife to divide the rootball.
4. Replant each division in its own pot filled with fresh, well-draining soil.

It’s best to propagate during spring, when the plant is naturally entering its growing season. After division, water each new plant thoroughly and place it in a location with indirect light. With the right care, each division will establish quickly and grow into a healthy, independent plant.

Soil & Fertilizer for Peace Lily Plants

The right soil mix plays a big role in the overall health of your peace lily. This plant prefers a rich, well-draining potting mix—something that holds moisture without becoming soggy. A blend made for tropical houseplants or one with peat moss, perlite, and compost works well.

Best Soil Tips:

• Use a high-quality potting mix (avoid garden soil)
• Add perlite or bark for drainage
• Keep soil moist but never waterlogged

Fertilizer Needs:

Peace lilies aren’t heavy feeders. In fact, too much fertilizer can damage the plant and cause brown leaf tips. Use a balanced houseplant fertilizer every 6 to 8 weeks during the growing season (spring through early fall). Always dilute the fertilizer to ¼ strength to avoid chemical burn.

Avoid fertilizing in winter, when the plant’s growth naturally slows down. If you notice leaf tip browning or yellowing after feeding, ease off for a while—this plant will thrive with less, not more.

Problems, Pests & Diseases

Peace lilies are generally easygoing, but like any houseplant, they’re not immune to problems. The good news? Most issues are preventable with proper care.

Common Problems:

• Root Rot: The most frequent issue with this plant comes from overwatering. Ensure your pot has good drainage and avoid letting it sit in standing water.
• Brown Leaf Tips: Usually caused by overfertilization or low humidity. Use diluted fertilizer and consider misting the plant in dry environments.
• Drooping Leaves: Often a sign that the plant is either too dry or too wet. Feel the soil to determine which it is before adjusting your watering routine.

Pests to Watch For:

• Mealybugs and scale insects may occasionally appear, especially if the plant is stressed. Treat infestations by wiping the leaves with a damp cloth or using insecticidal soap.
• Dust buildup on leaves can block sunlight. Gently wipe the leaves with a soft, damp cloth once a month—skip commercial leaf shine products, which can clog the plant’s pores.

For a thorough clean, place the plant in a sink or shower and let lukewarm water run over the leaves briefly.

Peace Lily Varieties

There’s more than one type of peace lily to grow indoors. While all share the signature white blooms and glossy leaves, peace lily varieties differ in size, leaf texture, and bloom production. Choosing the right plant depends on how much space you have and the look you’re going for.
