Do you adore your peace lily plant and wish you had more of them around your home?
Or perhaps you want a thoughtful, homegrown gift for a friend?
Whatever your reasons may be, the good news is that you can propagate your beloved peace lily — multiplying its beauty in a sustainable, budget-friendly way.
This guide is your one-stop resource for the best practices and considerations in peace lily propagation.
Key Considerations When Propagating Peace Lily Plants
The peace lily is a resilient plant, but that doesn’t mean propagation can be done without proper planning and care.
Here are some factors you should consider to propagate peace lily plants successfully:
- The peace lily plant’s health: The mother plant must be healthy before you begin propagation. An unhealthy peace lily could produce weak offshoots or divisions.
- The right time: Peace lilies should ideally be propagated during early spring or summer when the plant is actively growing.
- Proper tools: Always use clean, sharp gardening tools to prevent the transmission of disease or infection.
- Potting mix: A well-draining, rich soil is necessary for peace lilies to thrive.
Understanding Peace Lily Plant Division
Peace lily plant division is the most common method used for its propagation.
The technique involves splitting the plant into several parts, each containing a section of roots and at least one or two leaves.
Why Choose Division?
Division is a natural method of propagation that many plants, including the peace lily, undergo in the wild.
The division process mimics these natural tendencies and is usually successful when done correctly.
Another important point is division allows you to control the size of the parent plant.
Over time, peace lilies can become crowded in their pots.
Repotting peace lilies isn’t the only way to give your plant a better life—division can help rejuvenate it, stimulate growth, and maintain its health.
Step-By-Step Guide To Propagating A Peace Lily
Choose the Right Time
The best time to propagate your peace lily is early spring or summer when the plant is actively growing.
Prepare Your Tools
You’ll need a sharp, clean serrated knife, garden shears, a new pot with enough drainage holes and fresh, well-draining potting soil.
Sterilising your tools is critical to avoid transmitting any diseases to the plant.
Remove the Plant from Its Pot
Put the plant pot on its side and gently remove the peace lily.
Be careful not to damage the root system as you do this.
Identify the Divisions
Inspect the root ball of your peace lily and cut off any black or mushy roots.
You should be able to see natural divisions where the plant has developed separate crowns.
Each of these can be turned into a new plant.
Time for Root Division
Gently cut and divide the root ball into multiple sections using your sterilised knife or shears.
Each section should have roots and at least two leaves, ensuring it has all the necessary parts to grow independently.
Don’t worry if you cut some roots in this process! Your plant will recover.
Repot the New Peace Lily Plants
Place each peace lily division into a new pot filled with fresh potting soil.
Make sure to bury the roots, but avoid covering the base of the stem.
Care for Your New Peace Lilies
Water the newly potted divisions thoroughly, then place them in a warm, brightly lit location.
Avoid direct sunlight, as it can burn the leaves.
Monitor Their Progress
Keep a close eye on your new peace lily plants for the first few weeks.
They might go through a bit of shock after being divided, but don’t worry — this is normal.
Continue to care for your peace lilies by keeping the soil moist and providing bright, indirect light.
Eventually, your propagated plants will become mature peace lily plants with dark green foliage.
How to Propagate Peace Lily in Water
Though it’s not the traditional method, propagating peace lilies in water is possible.
This technique lets you observe the root development, making it an exciting process.
Timing and Tools
As with soil propagation, spring or summer is the best time for water propagation.
Gather a sharp, clean knife or shears, a clear glass or jar, and room-temperature water.
Remove and Divide the Plant
Gently lift the peace lily from its pot and rinse the roots to remove any soil.
Identify natural divisions in the plant, each with its own root system and leaves.
Cut these divisions using your sterilised tool.
Prepare Your Container
Fill your glass or jar with room-temperature water.
The container should be deep enough to hold the roots of the plant division but avoid submerging the leaves.
Place the Division in Water
Position the peace lily division in the container so the roots are underwater, but the leaves and stem remain dry.
Don’t submerge the leaves, as this could lead to root rot and other issues later on.
Choose the Right Location
Put the container in a location with bright, indirect sunlight.
Direct sunlight can make the water too hot and damage the plant’s roots.
Change the Water Regularly
To prevent bacteria and algae growth, change the water in the container every few days.
Monitor Root Development
Keep an eye on the roots. After about 2–3 weeks, you should start to see new roots growing.
Transfer to Soil
Once the roots have grown to around 5–7 cm long, the peace lily is ready to be transferred to a pot with well-draining soil.
This transition allows the plant to receive nutrients essential for its growth and longevity.
How Long Does It Take Peace Lily Plants to Propagate?
When propagating peace lilies via division, you will likely see new growth within a few weeks after dividing and repotting the plant.
However, it may take several months (typically 3-4 months) for the new plants to become well established and begin to show vigorous growth.
Do Peace Lilies Grow From Cuttings?
Unlike many other houseplants, peace lilies do not grow from leaf or stem cuttings.
Peace lily propagation relies on division, specifically of the root ball, which contains all the necessary parts of the plant to create a new one.
Peace Lily Care and Growth Expectations
After propagation, it’s important to have realistic expectations.
Peace lily plants usually bounce back quickly after division, often producing new growth within a few weeks.
However, the plant’s full maturity could take 3 to 5 years, depending on the care and conditions provided.
FAQs About Peace Lily Propagation
Are peace lily plants hard to propagate?
Peace lily plants are relatively easy to propagate through division, making them a good choice for beginners.
Can you grow a peace lily plant from a broken leaf?
No, peace lilies cannot grow from a broken leaf. They propagate through the division of the root ball.
Can you propagate peace lilies from seed?
While peace lilies can technically be propagated from seeds, this is not a common or recommended practice due to its complexity and low success rate.
Can a peace lily live in water forever?
Yes. However, you will need to follow a specific guide to grow peace lilies in water.
You can’t just repot your peace lily into water without preparing for transplant shock and other possible issues.
Be the Pro in Propagation
Propagation is an exciting aspect of being a seasoned gardener.
It allows you to multiply your favourite plants, such as the peace lily, and share them with others.
Remember that the key to successful propagation is careful preparation, proper technique, and patience.
With these elements in place, you’ll soon have more peace lilies gracing your indoor garden.
