How to Propagate Peace Lily? [Stepwise Guidance]

If you avoid direct pulling of the mother plant and reduce the stress initiated due to the splitting, you can successfully propagate a Peace Lily.

Generally, Peace Lily can be propagated effortlessly via division while keeping each root and crown of the mother plant intact. Also, you may replicate these magnificent plants through seed. However, it takes a long time for these beauties to thrive afterward.

So, understand the successful methods to propagate the Peace Lily, and fill your area with its pleasant scents by reading the article till the end.

Best Time to Propagate Peace Lily

There is no ideal time or season for reproducing your Peace Lily, as it entirely depends on the zone you reside in and the plant’s growth pattern.

For the ones living in the warmer zone (USDA 10-12), you can propagate the indoor Peace Lily any time of the year except for the winter.

Otherwise, most gardeners await spring to propagate their outdoor Peace Lily.

As for the colder zones, wait for the spring or summer with the day temperature reaching 65ºF or above indoors, as cold drafts can affect the healthy growth of the plant and stress them out.

However, check out for dry soils, which is highly possible during summer as it obstructs the plant’s mineral uptake, making it wilt and die.

Also, you can propagate your Peace 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.

Excessively bounded roots lead to unhealthy competition for nutrients.

Nonetheless, this causes insufficient nutrition absorption by roots, resulting in drooping leaves and roots poking out of the soil.

Thus, you need to either propagate the plant or replace the pot to solve the issue.

Methods for Propagating Peace Lily (Spathiphyllum wallisii)

Peace Lily is a little demanding for propagation compared to other houseplants as they have limited proliferation methods.

The most probable ways to reproduce the Peace Lily include the division (crown) and seed methods usually performed during the spring.

If you are wondering about the stem or leaf cuttings, it would be a waste of time, as Peace Lily cannot establish its root from these.

1. Via Division (Crowns)

Peace Lily plants create distinct baby clumps as they grow with about two to three leaf clusters, known as crowns, having the same joint beneath the soil.

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

However, only mature plants with enough new leaf clumps can be suitable for the division propagation method.

Also, it is the most effective, quickest, and easiest way of propagating Peace Lilies.

Look at the step-by-step procedure to follow during propagation by division.

Step 1: Examine and Prepare the Plant

First, you need to find Peace Lily plants that produce many juvenile crowns.

Peace Lilies do not develop on a solitary stem or stalk, giving new leaves immediately from the surface.

Later, it will establish its root systems and give out many crowns to proceed with further propagation.

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.

Remember 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.

If your Peace Lilies do not come out of the pot, your final resort is to smash the pot wide open.

Just ensure your Peace Lily does not break off under any circumstances.

Step 3: Separate the Crown

If you separate clumps meticulously, your Peace Lily plants will thrive, whereas if you adopt carelessness, you might end up regretting afterward.

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

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

Following crown separation, you can identify the root systems of the young clusters from the parent plant separately.

Lastly, remove the sole root attached to the parent plant.

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

Step 4: Transplanting the Crown

After clump separation, select the pot size with 2 to 4 inches diameter made up of clay or plastic with a drainage hole.

Prepare a soil mixture like Miracle-Gro Potting mix with 6.5 to 7 pH. Ensure the soil contains vermiculite, leaf humus, perlite, sand, and peat moss.

Two different black pots containing the Peace Lily is lying over a floor.
Ensure that each crown has at least three to four leaves before propagating.

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

Step 5: Care After Transplanting

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

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

Remember that if you observe such, do not water your newly transplanted Peace Lily out of worry.

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

Also, maintain the temperature between 65ºF and 75ºF for the first few weeks.

Lastly, your Peace Lily must avoid direct sunlight, so keep it in a shaded or dimly lighted room.

By doing so, you are ready to see the new leaves of Peace Lily within 6 months.

2. Via Seeds

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

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

Also, it takes over six months to give the first seedling, a year to give a fully grown plant and several years to give the first bloom.

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

So be careful with every step you take while propagating them from seeds if this is your first time.

Step 1: Harvest the Seed

First, the Peace Lily should have successful fertilization to extract the seeds.

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

After fertilization and seed pod maturation, meticulously extract the seeds by cutting the spadix open with a sterilized gardening knife or pruners.

Step 2: Planting Seeds

Use a suitable sterilized germination soil mix containing peat moss, sand, perlite, and other non-soil components.

Bury those seeds but not deep within completely. Instead, cover them with light soil and sprinkle some vermiculite on top. Following that, you should softly water it.

The propagated Peace Lilly will require good humidity (70 to 80%) and plastic to cover the pot.

Note that the color of the plastic you are using shouldn’t be black as it heats too fast and can store warmth, raising the temperature above 85ºF.

Can you Propagate Peace Lily in Water?

Surprisingly you can reproduce the charming Peace Lily in water, but the process is loaded with all the troubles one tries to avoid.

Nevertheless, let me provide steps for propagating Peace Lily in water by using the divided crowns:

  • First, fill the jar container with tepid rainwater or distilled water (more than half of the container).
  • Discard using tap water with high minerals, including chlorine and fluorine, as it can cause brown edges on the leaves of your Peace Lily.
  • 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.
  • Ensure its root is submerged, and add water-soluble fertilizers to enhance rooting.
  • Lastly, change the water every 4-5 days.

However, I recommend buying already propagated Peace Lily in water rather than trying it out since you might lose your prized Peace Lily.

Nevertheless, if you have cut foliage having no roots attached, propagate the leaf of Peace Lily in water to try out your luck in initiating rooting.

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

The number of new plants depends on the crowns from your Peace Lily plant.

On average, you can get two to six new Peace Lily plants from every mature mother with enough crowns.

And if the mother Peace Lily size is big enough with well-developed crowns, you can get around 20 new plants.

Moreover, you can continue propagating the Peace Lily from the same plant if it produces a developed crown from its rootball with maintained healthy growth.

Tips to Care for Peace Lily After Propagation

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

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

  • Maintain the temperature between 65ºF and 85ºF and protect from frost (<60ºF).
  • The best humidity level for Peace Lily is 70 to 80%. So, maintain it by using a humidifier or pebble tray.
  • Restrain from over-watering to save your Peace Lily from root rot. Keep a watering schedule to weekly and misting to twice a week.
  • Keep your Peace Lily facing north or west-facing window, allowing indirect medium-to-bright light to fall upon it.
  • Supply it with monthly houseplant NPK fertilizer consisting of 20% of each component.
  • Swipe the Peace Lily leaves weekly with a damp cloth to keep pests like fungus gnats, mealy bugs, spider mites, and scales at bay.
  • Do not keep many plants nearby the newly propagated Peace Lily to avoid the risk of contamination from diseases like a mosaic virus or root rot by Phytophthora.
