Peace lilies can’t grow from cuttings—surprising, right? But don’t worry, there’s a better way to multiply them, and it’s simpler than you’d expect.
Root division is the secret, and I’m here to break it down for you, step by step.
I’ll walk you through the two main methods—root division in soil or water—and show you everything you need to propagate your peace lily successfully.
Let’s dive into the basics and get you started on creating your own thriving peace lilies!
What Does Propagation Mean for a Peace Lily?
Propagation is how you make new plants from an existing one. For peace lilies (Spathiphyllum), it’s like splitting one plant into two or more to grow separately. It’s a natural process that helps your indoor garden thrive.
Why Can’t You Propagate Peace Lilies from Stem Cuttings?
Peace lilies cannot be propagated from stem cuttings. Their stems don’t have the right structure to sprout roots. Instead, we rely on dividing the roots. Root division in soil or water is the most effective way to propagate a peace lily.
The Only Method of Propagation for Peace Lilies: Root Division
Root division involves dividing the peace lily’s root ball into smaller sections. Each piece needs roots and leaves to grow on its own. It’s straightforward and works every time if you follow the steps.
Benefits of Propagating Peace Lilies
Propagating gives you free peace lilies and prevents root overcrowding. Plus, more plants mean more oxygen and beauty in your home. Once, I divided a big peace lily and ended up with three thriving ones—it felt like magic!
When to Propagate Peace Lily
Best Time of Year for Propagation
The best time to propagate a peace lily is early spring to early summer. This is when the plant is growing strong, says the University of Florida Extension (edis.ifas.ufl.edu). Warm weather helps new roots settle in faster.
Signs Your Peace Lily is Ready to Be Divided
How do you know it’s time? Look for these clues:
- Overcrowded roots: Roots peek out of the drainage holes or circle the pot.
- Plant outgrowing its pot: The peace lily looks too big for its home.
- A large, mature plant: It’s big enough to split into smaller sections with roots and leaves.
If you see these signs, grab your tools—it’s propagation day!
Tools That You’ll Need
Before propagating your peace lily—whether in soil, water, or from seeds—gather these simple tools:
- Sharp, clean scissors or knife
- Small pots (4-6 inches) with drainage
- Potting soil (indoor mix with perlite)
- Clear jar (for water method)
- Fresh, room-temperature water
- Shallow tray and seed-starting mix (for seeds)
- Plastic wrap, watering can, and tray/towel
With these tools in hand, let’s start with soil propagation!
How to Propagate Peace Lily via Root Division
Step-by-Step Instructions for Root Division (Soil Method)
Propagating a peace lily in soil is simple and fast. Here’s how I do it:
- Remove the peace lily from the pot – Gently pull the plant out. Be careful not to break the roots.
- Examine the roots – Look for natural splits or sections you can separate.
- Separate the plant into sections – Use clean, sharp scissors or a knife to cut the root ball. Make sure each piece has roots and leaves.
- Trim any damaged or dead roots – Cut away brown or mushy parts so the new plants stay healthy.
- Potting – Plant each section in its own pot with fresh potting soil. I use a mix made for indoor plants.
- Watering – Water lightly and put the pots in a warm, humid spot. This helps roots grow strong.
The University of Florida Extension says fresh soil gives new divisions the nutrients they need. It’s worked for me every time!
Quick Recap
So, pull the plant out, find the splits, cut it up, trim bad roots, pot it, water lightly, and set it somewhere warm—that’s all you need for new peace lilies!
Propagating Peace Lily in Water (Alternative Method)
Step-by-Step Instructions for Water Propagation
Water propagation is an alternative method for peace lilies. It’s a little slower but lets you watch roots grow. Here’s the process:
- Prepare the peace lily – Cut the root division like you would for soil.
- Place in water – Put the roots in a jar of water. Keep the leaves above the waterline so they don’t rot.
- Wait for roots to grow – Change the water every few days. Roots take about 2-4 weeks to form.
- Transfer to soil – When roots are a few inches long, move the plant to a pot with soil.
This method isn’t as common, but it’s fun to see the roots sprout. I tried it once and loved watching the white tendrils form in the glass!
Quick Recap
Here’s the short version: Cut a division, put the roots in water, keep leaves dry, change the water often, and pot it in soil when roots are long. Easy and fun!
How to Propagate a Peace Lily from Seed
Step-by-Step Instructions
Propagating a peace lily from seed takes more time and effort. It’s not as fast as root division, but here’s how:
- Collect Seeds – Pick ripe seeds from peace lily flowers after they bloom.
- Plant the Seeds – Use a shallow tray with seed-starting mix. Barely cover the seeds with soil.
- Moisture – Keep the soil damp and warm—around 70°F works best. Cover the tray with plastic to trap humidity.
- Transplant Seedlings – When seedlings pop up, move them to small pots.
Peace lily seeds germinate in 2-3 weeks. It’s slower than division, but I find it exciting to grow a plant from scratch.
Quick Recap
Grab ripe seeds, plant them in a tray with light soil, keep it damp and warm under plastic, wait 2-3 weeks for seedlings, then move them to small pots—slow but exciting!

Water Propagation vs. Soil Propagation for Peace Lily: Which is Better?
Water Propagation
Water propagation allows your peace lily to grow roots before transferring to soil.
Pro: You can see the roots develop and adjust them.
Con: If you forget to change the water, the roots might rot.
Soil Propagation
Soil propagation is the quickest way to produce a healthy peace lily.
Pro: It’s simple and helps your peace lily recover fast.
Con: You need to watch the soil moisture closely so it’s not too wet or dry.
Conclusion
Soil propagation is the best method because it’s reliable. Water propagation works as a first step before planting in soil. I’ve tried both, and soil feels easier for me.
Aftercare for Propagated Peace Lilies
Caring for Root Divisions in Soil
New peace lily divisions require careful watering and light to grow. Water them every 5-7 days, keeping the soil moist but not soggy. Place them in bright, indirect light—like near a window with a sheer curtain—so they grow strong without burning.
To boost humidity, set the pots on a tray with pebbles and water or mist the leaves a few times a week. The University of Florida Extension says peace lilies love humid air, just like their tropical home. When the roots settle in (about 4-6 weeks), you can transplant them to bigger pots if they need more space.
Caring for Root Divisions in Water
If you’re growing roots in water, check the level daily. Keep the roots submerged but don’t let the leaves touch the water—they’ll rot. You’ll know it’s working when you see white, healthy roots growing longer, usually in 2-4 weeks.
Once they’re a few inches long, move the plant to soil for the best long-term growth. I once waited too long with a water division, and it got weak—soil is where they really shine.
Common Problems & Troubleshooting Peace Lily Propagation
Why Isn’t My Peace Lily Rooting?
Root rot, low light, or overwatering prevents peace lilies from rooting. This happens if there’s root rot (soft, brown roots), too little light, or overwatering.
Check the roots first—healthy roots feel firm like a carrot and shine white. Give them bright, indirect light and let the soil dry a bit between waterings.
Peace Lily Division Not Growing?
A division that won’t grow might lack humidity or be overwatered. It could also mean the section you cut didn’t have enough roots. The Missouri Botanical Garden notes that each division needs a solid root system to take off. Add a humidity tray and cut back on water to fix it.
Yellowing Leaves After Propagation
Yellow leaves after propagation indicate issues like overwatering or low light. I had this once after moving a new division—too much water was the culprit. Adjust light to bright but indirect and water only when the top inch of soil feels dry.
How to Fix Root Rot in Propagating Peace Lilies?
Root rot looks like mushy, dark roots and smells bad. Prevent root rot with well-draining soil and minimal water. If it happens, cut away the rotten parts with clean scissors, repot in fresh soil, and water lightly. The University of Florida Extension warns that overwatering is the top killer of peace lilies.
Tips for Successful Peace Lily Propagation
Here are my best tips to make propagation easy:
- Use clean, sharp tools – Dirty scissors can spread germs. Clean them with rubbing alcohol first.
- Divide in spring or early summer – The plant’s growing season helps it recover fast.
- Avoid overwatering – Too much water rots roots. Stick to a light schedule.
- Give bright, indirect light – It’s the sweet spot for new growth.
- Boost humidity – Use a tray with pebbles and water or mist the leaves. Peace lilies love it moist but not wet.
These steps have worked for me every time I’ve split a plant.
FAQs About Peace Lily Propagation
Can You Split a Peace Lily?
Yes, you can split a peace lily by dividing its roots and repotting each section. The best time to divide a peace lily is in spring or early summer when it’s actively growing.
Can You Propagate a Peace Lily from Cuttings?
No, peace lilies can’t grow from cuttings. Their stems won’t root like other plants, so stick to root division or seeds. It’s the only way that works.
Can I Propagate a Drooping Peace Lily?
Yes, you can propagate a drooping peace lily if the roots are healthy. A drooping peace lily can still be divided using soil or water methods. Just check the roots and care for the new plants gently.
Do Peace Lilies Grow Better in Water or Soil?
Peace lilies grow well in both water and soil, but they thrive best in soil. Soil provides nutrients and stability, while water-grown plants require regular fertilization to stay healthy. Soil’s my go-to after experimenting with both.
Can Peace Lilies Be Propagated in Other Mediums?
Peace lilies propagate best in soil or water, but sphagnum moss can work too. It’s less common and trickier to keep moist without rotting. Stick to soil unless you’re curious to try it.
How Long Does It Take for Peace Lily Seeds to Germinate?
Peace lily seeds take 2-3 weeks to sprout. Keep them warm and damp under plastic, and they’ll pop up if conditions are right. It’s slower than division but doable.
How Do I Know If My Propagated Peace Lily is Healthy?
A healthy peace lily shows green leaves, firm roots, and steady growth. Yellow leaves or weak stems mean something’s off—check water, light, or humidity. Adjust fast to keep it happy.
Conclusion
Propagating peace lilies through root division is the best way to grow new plants. Whether you choose soil or water, both methods can work with the right care. It takes a little patience, but soon you’ll have a home full of lush green peace lilies.
Why not give it a try and build your own little jungle? It’s easier than it sounds!
