How to Propagate Peace Lily (Spathiphyllum)?

Peace Lilies are one of the greatest plants for adorning your area with a pleasant scent and enhancing the appearance of the space.

I had them in my room a few years ago, but I had to give them away to my niece, who is enamored with plants because of my hectic schedule.

However, while cultivating Peace Lily, I learned a lot of things, including perfect ways to look after and propagate it.

Peace Lily can be propagated effortlessly via division while maintaining both the root and crown of each portion intact. You may replicate these magnificent plants through seed; nevertheless, it takes a long time for these beauties to thrive afterward.

I’d want to share some important propagation, care, and growth tactics for Peace Lilies with you based on what I learned when growing them.

Best Time to Propagate Peace Lily

There is no ideal time or season for reproducing your Peace Lily in particular.

Furthermore, the appropriate period for propagating Peace Lilies is entirely dependent on a variety of criteria.

Without further ado, let us examine the aspects that must be addressed while propagating your Peace Lily.

1. Propagation in the Spring season

The first thing to be considered is that Peace Lily loves the purity of the air in spring and thrives at this time of the year.

Most gardeners await the spring season to propagate their outdoor Peace Lilies.

If we propagate these plants during the winter, their growth is considerably slow.

As for summer, soils can dry out quickly; as a result, peace lily plants can wilt and die since the mineral required by it cannot be absorbed from the soil.

2. Propagate When your Peace Lily Plant Outgrows the Pot Size

You should propagate your Lily if it has outgrown the size of the pot.

Peace Lily plants grow fast, and as a result, their roots take up all of the available space in the pot quickly.

Nonetheless, this causes insufficient nutrition absorption by roots, resulting in drooping leaves.

Also, the roots of your Peace Lily plant begin to emerge from the soil.

Then it’s obvious that you need to either propagate the plant or replace the pot.

Materials Required to Propagate Peace Lily

To propagate any plant, we will first require a few certain tools.

Here is the list of pieces of equipment you will need while propagating your beautiful Peace Lily.

  • Sterile Knife: You will need to cut the Peace Lily to cut it into parts as these plants are propagated through the division method.
  • Soil Mix: Prepare an appropriate soil mixture like Miracle-Gro Potting mix with 6.5 to 7 pH. Ensure that the soil contains Vermiculite, Leaf Humus, Perlite, Sand, Peat moss.
  • Old Peace Lily plant: We will need an old Peace Lily to begin our propagation in general.
  • Pot: Select the pot size with 2 to 4 inches diameter of clay or plastic with a drainage hole.

Methods of Propagating Peace Lily (Spathiphyllum)

Peace lily (Spathiphyllum) can not be propagated using stem or leaf cuttings.

However, only a couple of ways are applicable to reproduce our delicate and charming Peace Lily plant.

These two methods are Propagation by Divison (Crowns) and Propagation by Seed.

Let us check details about both these processes, and I’m pretty sure Propagation of Peace Lily (Spathiphyllum) will be a cakewalk for you afterward.

1. Propagate Peace Lily Via Divison (Crowns)

Peace Lily plants create several baby clumps as they grow.

Then, fresh foliage emerges from the ground because the plant does not have a single trunk or stalk.

The new roots’ buds gradually grow into different plants with their root systems that can readily support them.

Only mature plants with enough new leaf clumps can benefit from the division propagation method.

Well, this is the most effective and easiest way of propagating any plant, not just your Peace Lilies.

Let’s go through a step-by-step procedure to follow during Propagation by division.

Step 1: Examine and Prepare the Plant

First and foremost, you ought to know if your Peace Lily is appropriate for carrying on the Propagation.

As you may know, Peace Lily plants produce many juvenile crowns and do not develop on a solitary stem or stalk.

As a result, the new leaf emerges immediately from the surface.

Following that, the freshly emerging roots’ buds grow into different plants.

Later on, it will establish its very own root systems and begin to grow by itself. This is why divisional Propagation is the most effective way for propagating your Peace Lilies.

Besides, if you observe many crowns, you can proceed to further propagation steps.

Step 2: Take the Root Ball out of the Pot

When you believe your Peace Lily is ready for Propagation, gently remove the entire plant from the pot.

Keep in mind that if you can’t pull out your plant alone, consider taking it out with the entire soil intact by carefully pounding on the container.

Just in case if your Peace Lilies do not come out of the pot, your final resort is to smash the pot wide open.

Just make completely sure your prized Peace Lily does not break off under any circumstances.

Step 3: Separate the Crown

Crown seperation is the most crucial step in performing the Propagation of your Peace Lily via the division method.

If you separate clumps meticulously, then your Peace Lily plants will thrive, whereas if you adopt carelessness, you might end up with hands-on head regretting afterward.

Scrape the dirt intact to the bases carefully while preserving the root structure.

Furthermore, the most efficient approach to remove soil is to cycle between your hands and a tiny rake instrument.

Following crown separation, the root systems of the young clusters from the parent plant may be identified separately.

The sole root attachment between the parent plant and other roots should be removed.

Remember that crowns with few foliages and an immature root system should not be separated.

Step 4: Transplanting your Peace Lily (Spathiphyllum)

After clump separation, you will need to take care of other aspects like choosing proper soil mix and appropriate care after replanting Peace Lily.

Once you have chosen an appropriate soil mix and vessel, it is time to transfer your baby clumps into it.

Step 5: After Care

Just like any other plant, your Peace Lily will also show signs of propagation shocks.

As a result, the leaves of your beautiful plant might fall and droop.

Keep in mind that if you observe such, then out of worry, do not water your newly transplanted Peace Lily.

In addition, this will further deteriorate the situation since your plant’s roots might rot, causing the death of your prized peace Lily eventually.

Last but not least, your Peace Lily must avoid direct sunlight, so it should be kept in a shaded or dimly lighted room.

Also, maintain the temperature beyond 77 degrees Fahrenheit (i.e., 25 degrees Celcius).

2. Propagate Peace Lily Via Seeds

Another method applicable for propagating your Peace Lily is by using the seeds.

Peace lily seeds take a long time to germinate, whether harvested from plants or purchased online.

However, using seeds, the Peace Lily propagation will give you offspring different from its mother plant.

On the other hand, the growth rate of Peace Lilies propagated via seeds takes over six months to grow.

Usually, this Propagation method is carried out only by gardeners as they want a different variety of Peace Lily.

Besides, this way of Propagation is also tedious and troublesome might result in the death of the mother and the new Peace Lily plant.

I suppose you don’t want that, so stick with the easy and efficient way of Propagation of your Peace Lily by using a divisional method.

Step 1:  Harvest the Peace Lily Seed

First of all, your Peace Lily’s seeds must be fertilized to carry out this type of Propagation.

Well, you can easily know if your beauties are fertilized or not by simply looking at the spathe.

If the spathe of the white-colored Peace Lily flower changes into green and if spadix (yellow) turns brown, it is fertilized and ready for seed propagation.

After fertilizing your Peace Lily, meticulously extract the seeds by cutting spadix open.

Not to mention that the spadix-cutting instruments must be disinfected to avoid infection.

Step 2: Planting Seeds of Peace Lily

After you’ve extracted the Peace Lily seed, it’s time to plant it.

Keep in mind that soil-borne pathogens may attack your newly sown seeds, causing them to decay and eventually undermining your Peace Lily growth.

To avoid this, use a suitable germination soil mix. These soil mixes typically include peat moss, sand, perlite, and other non-soil components.

You may sow the seeds on top of the perfect germination mix once you’ve chosen it.

Be cautious not to completely bury those seeds deep within; instead, cover them with light soil and sprinkle some vermiculite on top. Following that, you should softly water it.

Aftercare of the propagated Peace Lilly will require a good humidity (70 to 80%), covering of container with plastic.

Note that the color of plastic that you are using shouldn’t be black.

Also watch,

Propagate Peace Lily in Water

Although you cannot propagate your Peace Lily through steam or leaf cutting, surprisingly, you can reproduce the charming Peace Lily in water.

From my experience, when I tried to propagate these beauties in water, I had to go through loads of trouble in due process.

And if you must know, the result was not satisfactory as well.

Nevertheless, let me provide steps of propagating Peace Lily in water in brief:

  • First, fill the jar container with adequate water (more than half of the container). The water you use must be either rainwater or distilled water.
  • Bear in mind that you must not use water that contains high minerals, including chlorine and fluorine that means avoid tap water as it can cause brown edges on the leaves of your Peace Lily.
  • After completing the preceding procedure, drill a hole in the center of the vessel’s lid.
  • Then place the drilled lid into the jar such that your Peace Lily passes right through the hole to keep your plant upright.
  • Make sure its root is submerged into water, and to enhance rooting, add water-soluble fertilizers.

Even though these steps sound quite simple; however, I would recommend you to rather buy the already propagated Peace Lily in water than try it out yourself since you might lose your prized Peace Lily in the process.

How Many New Plants can be Grown from Peace Lily Propagation?

You can get two to six new Peace Lily plants for every mother plant.

However, the number of new plants completely depends on the crowns sprouted by your Peace Lily plant.

And if you are wondering how many times you can propagate your precious, then the straightforward answer to your question would be just as long as your Peace Lily produced crowns.

Tips to Care for Peace Lily After Propagation

Once you have completed your Propagation, now it is time to care and look after your Peace Lily like a baby.

Here are some steps that you can grasp and apply afterward:

1. Temperature Requirement

The temperatures of over 60 degrees Fahrenheit and below 70 degrees Fahrenheit will suffice the growth of your Peace Lily.

Make sure to avoid extreme dryness of the soil.

In addition, cold temperatures like in winter can cause frosting, which damages the plant tissue of Peace Lily, resulting in wilting and eventually dying off.

2. Humidity Requirement

High-humidity tenting is beneficial for Peace Lily to thrive. And as a result, the best humidity level for Peace Lily is 70 to 80%.

You can use moisture bags, use of pebble tray, a grouping of plants can help to increase humidity.

3. Prevent Root Rot

The root rotting is one of the major reasons that cause the death of Peace Lily. So always choose a proper soil mix and a pot with ample drainage hole.

Also, over-watering must be avoided to save your Peace Lily from rotting the root.

4. Adequate Lighting

The ideal light condition for growing a Peace Lily is indirect & medium-to-bright lights.

However, you should not keep your precious plant in dark or shaded reason rather it should be kept in a room with sunlight in the morning and its shades in the daytime.

In addition, it is recommended to keep your Peace Lily facing North or West direction as it will not get direct sunlight all day.

4. Adequate Watering

Once transplanting, provide your peace lilies with adequate water after the Propagation is over.

Afterward, make sure you do not water these delicate plants since they might cause root rotting due to overwatering.

Also, newly propagated plants require lesser water compared to ordinary plants. So, it will be best to water after a week of propagation.

In addition, propagated peace lily must be watered only once a week and mist the leaves twice a week.

5. Fertilizer Requirement

Generally, Peace Lily tends to thrive even without minimal fertilizers.

However, if you need it to grow quickly and substantially, supply it with house plant NPK fertilizer consisting of 20% of each component.

Furthermore, only apply fertilizers in 4 weeks gap duration.

6. Control of Pest & Disease

Following the propagation of Peace Lilly, it can be more susceptible to pests and diseases. So, extra care is needed.

To maintain your plant pest-free and healthy, you can gently swipe the Peace Lily leaves every once a week and do not keep many plants nearby the newly propagated Peace Lily to avoid the risk of contamination.

Also, if the leaves seem to be unhealthy, then gently cut them off so that they will not transmit pests and disease to the whole plant.

Also watch,


Growing and Propagating Peace Lily plant is a piece of cake once the newly potted plant adapts and begins to grow since these adorning plants require very little care.

Peace Lily grows lasts for over three years to avoid frequent errands to plant store.

Also, by the the time your first plant dies off, you will have plenty of Peace Lily courtesy of its quick and efficient Propagation.

The perks of cultivating Peace Lily are sleep promotion, air purification, resist mildew formation in the kitchen, absorption of toxic chemicals, eradication of mold spores.

To sum it up, these lovely and gorgeous plants can be propagated and used as a gift idea for any auspicious occasion.
