Peace lilies are a popular and elegant houseplant, not only for their beautiful white flowers but also for their easy maintenance and air-purifying properties. Propagating a peace lily can be a fulfilling project for a gardening or houseplant enthusiast, as it allows them to multiply their beloved plants and enjoy even more peace lilies. In this article, we will provide you with valuable tips on how to successfully propagate your peace lily through various methods.

One method of peace lily propagation is through clump division, which involves separating baby plants from the mother plant and growing them separately. This technique is faster than reproducing through seeds, and it allows the new plants to inherit the desirable traits of the parent plant. Another propagation method involves using soil, water, or even an alternative growing medium like LECA or perlite for the young plant to grow.

To get the best results when propagating a peace lily, it’s essential to begin the process when the parent plant is mature, and for outdoor plants, during warm seasons like spring or summer. Indoor peace lilies can be propagated any time of the year since temperature control is more manageable. Stay tuned for more insights on each propagation method and learn how to expand your peace lily collection successfully.

Understanding Peace Lily Propagation

Importance of Propagation

Propagation is a crucial aspect of plant care as it helps in increasing the number of plants without having to buy new ones. For peace lilies, propagation ensures healthy growth and development, allowing the plant to thrive in diverse indoor environments. Additionally, propagating peace lilies makes for an excellent way to share these beautiful plants with friends and family.

Propagation Methods

There are several methods to propagate peace lilies, each with its own advantages and considerations. The most common and efficient method is through division. Let’s explore some of these methods in a step-by-step form.


  1. Gently remove the peace lily from its container. Avoid pulling the stems too hard, as it may damage the plant. Tapping or squeezing the sides of the pot can help loosen the soil ^(source).
  2. Separate the plant by separating the roots and stems, creating two or more sections.
  3. Replant each section into a suitable pot with appropriate potting mix.
  4. Keep the new plants at temperatures above 55°F and below 85°F, with high humidity for the first few days after propagation ^(source).
  5. Allow the soil of the newly propagated peace lilies to dry out a little between its watering cycles.

Other propagation methods include using sphagnum moss or LECA (Lightweight Expanded Clay Aggregate) ^(source). These methods are particularly popular for houseplants and can be used for both rooted and unrooted sections.

Regardless of the method used, it is essential to provide peace lilies with enough bright light for them to grow and thrive after propagation ^(source). Proper care, regular monitoring, and following the propagation steps are crucial for attaining a successful peace lily propagation journey.

Preparation for Propagation

Choosing the Right Plant

Before you begin propagating peace lilies, it’s crucial to choose a healthy plant. Inspect the plant’s stem and leaves for any signs of pests, diseases, or damage. A healthy stem should be at least 4 inches in length with at least three nodes where the leaves attach. It is ideal to select a mature plant or one that has just finished flowering to ensure successful propagation.

Gathering Materials

When you’ve identified the ideal plant, gather the appropriate materials needed for propagation. Here are some essential supplies you will need:

  • A clean, sharp knife or pair of scissors
  • A well-draining pot between 4-6 inches in diameter
  • Fresh potting soil specifically for peace lilies or a mix of equal parts potting soil, perlite, and peat moss
  • A tray or saucer for the bottom of the new pot
  • Rooting hormone (optional, but may improve your chances of success)
  • Clean water for watering the plants

Before beginning the propagation process, have all materials ready at hand. Sterilize your cutting instrument by cleansing it with a mild bleach solution or rubbing alcohol. This will minimize the risk of transmitting diseases or pests from one plant to another.

Once the materials are prepared and your workspace is set, you can begin dividing your peace lily.

Dividing Peace Lily

When to Divide

Dividing a peace lily is best done during the early spring, when the plant is entering its active growth period. This allows the divided sections to establish faster in their new pots. It’s preferable to divide the peace lily when it becomes root-bound or when you notice the formation of new crowns, indicating the presence of baby plants.

Steps for Dividing

  1. Prepare the new pots: Select appropriately sized pots with drainage holes for each new section of the peace lily. Prepare a well-draining potting mix, such as a blend of peat moss, perlite, and vermiculite.
  2. Remove the plant from its pot: Gently tip the peace lily out of its current pot by turning it on its side and gripping the foliage. Lightly rock the plant to release it from the pot. Be careful not to damage the roots during this process.
  3. Inspect the roots and crowns: Examine the spots where the foliage is connected to the roots. Identify the crowns, which are the areas where new growth emerges.
  4. Separate the crowns and roots: Using a sharp and sterile knife, carefully cut the crowns with their attached roots from the main plant. It is important to include both the rhizomes and roots when dividing the plant.
  5. Pot the divided sections: Place each peace lily section in a new pot and fill it with prepared potting mix. Gently firm the soil around the roots to ensure adequate support.
  6. Water and care for the new plants: Water the newly potted peace lilies thoroughly to help settle the soil and provide needed moisture. Place the pots in a warm, well-lit location with indirect sunlight. Maintain consistent humidity and temperature to encourage strong root growth for successful propagation.

By following these steps, you can successfully divide your peace lily, creating new plants to enjoy or share with others. Remember to always use clean, sharp tools and provide proper care after division to ensure the health and vitality of your peace lilies.

Water Propagation

Choosing a Suitable Cutting

Selecting the right cutting for water propagation is essential to successfully propagate a peace lily. Look for a healthy and young section of the plant with at least one or two leaves. Detach the chosen cutting from the mother plant, making sure there’s a small section of stem and some roots left on it.

Root Development Process

To ensure ideal root formation, follow these steps:

  1. Fill a glass or vase with water, preferably distilled or tap water.
  2. Place the peace lily cutting in the container so that only the bottom part (previously under the soil) is submerged.
  3. Place the container in a well-lit area, avoiding direct sunlight as it may be too harsh for the cutting.
  4. Monitor the water level in the container and add more if needed to keep the stem submerged.
  5. Wait for roots to develop, which can take a few weeks. Keep an eye on the progress and be patient during this process.

As roots begin to appear, it is essential to maintain proper water levels and a suitable environment for your peace lily cutting. By taking care of your cutting and ensuring it has the necessary resources, you’ll increase your success rate in propagating your peace lily using water.

Caring for New Peace Lily Plants

Potting and Soil Requirements

When propagating your peace lily, it’s essential to provide the right potting environment for the new plants. Choose pots with drainage holes to prevent waterlogging. The pot size should allow for some root growth, but not be too large, as peace lilies prefer a snug fit.

As for the soil, aim for a well-draining mix such as a peat-based potting mix with added perlite or vermiculite. You can achieve the right balance by mixing:

  • 60% peat moss or coir
  • 20% perlite
  • 20% vermiculite

This mix will provide the right balance of drainage, water retention, and aeration for your new peace lily plants.

Watering and Light Needs

Watering is of the utmost importance when caring for peace lily plants. After propagation, ensure that the plants are in a warm environment (above 77°F or 25°C) to help them adjust. During the first couple of weeks after propagation, let the plant dry out slightly between waterings. Err on the side of caution, as over-watering can lead to root rot.

Peace lilies appreciate partial shade as direct sunlight can scorch their leaves. However, too little light may prevent flowering. The ideal location provides bright, indirect light for most of the day. Southern or eastern-facing windows are usually great spots for these plants.

Here’s a quick summary of peace lily care requirements:

  • Potting: Use well-draining, peat-based soil in pots with drainage holes.
  • Watering: Allow soil to dry out slightly between waterings, especially after propagation.
  • Light: Provide bright, indirect light; avoid direct sunlight to prevent scorching.

By following these guidelines, your newly propagated peace lilies are more likely to thrive and become healthy, mature plants.

Troubleshooting Peace Lily Propagation

Common Issues

Sometimes, peace lilies may face certain issues during the propagation process. One common problem is root rot, which can occur if the plant is watered too frequently or left in standing water. To prevent this, ensure proper drainage and allow the soil to dry out slightly between waterings. Another issue is wilted leaves, which can be caused by low humidity or insufficient watering. Maintaining high humidity levels, particularly after propagation, can help prevent wilting.

Peace lilies may also experience browning leaf tips, which can result from exposure to direct sunlight, chlorine in tap water, or dry air. Place your propagated peace lily in a well-lit spot, without direct sunlight, and use filtered or dechlorinated water to avoid this issue.

Tips for Success

Achieving success when propagating a peace lily can be relatively straightforward if you follow these tips:

  • Divide properly: Propagate your peace lily by division, which involves separating the plant into smaller sections, each with their own root system.
  • Temperature: Maintain a temperature between 55 and 85 degrees F, as this is the optimal range for peace lilies to thrive post-propagation.
  • Watering: Be careful not to overwater the plant; instead, let the soil dry out a bit between watering cycles immediately after propagating.
  • Humidity: Maintain high humidity for at least the first few days after propagation, misting the leaves if necessary.

By following these tips, you can successfully propagate your peace lily and keep it healthy and thriving.
