Why do you need to split a peace lily?

Peace lilies are incredible plants and great to have indoors. These plants produce a lovely white flower when mature, making it the reason people choose this plant in the first place. When it comes to splitting the plant there are two main reasons why it’s done.

  • Overgrown plant

Over time you may see the roots of your peace lily peeking from the top or bottom of the pot. This is indicative of the fact that the plant is too big for its pot. If left in the same pot the plant will not receive the required nutrients and will start to wilt.

This can easily be fixed by repotting the peace lily plant either into a bigger pot or by dividing the plant into 2 or 3 smaller plants.

  • Propagation

When you have a mature plant, propagation is a good option. This is when the mother plant is used to have saplings that can be grown and cared for as separate plants.

 How to split a peace lily?

Given below is a step-to-step guide on how to split a peace lily

Step-1: Deciding when it’s time to split a peace lily 

There are times when you have more than one plant and it is, to say the least, confusing when it comes to choosing the right plant to split.

For this, all you need to do is look for the most mature plant of the lot. The plant that has recently flowered is generally the more mature plant.

This can go another way when you have just one plant but are still confused if it’s time to split the plan. All you need to do is wait for the plant to mature and then go ahead with the division.

Step-2: Use sterilized equipment

Before you split a plant it is important to sterilize the equipment. This can be done using an over the counter disinfectant or you can make one at home. Either way, this is an important step as it protects the plant from bacterial infection and disease.

Step-3: Cover your counter

This is an obvious but overlooked point. As unpotting the plant is a messy process it is important to cover your counter to avoid cleaning.

Step-4: Loosen the soil

Before you start to tug at the plant to free it from the soil loosen it. This will not only reduce effort but also prevent damage. To loosen the soil all you need to do is stick a screwdriver or a twig and wiggle it around a little. You will also need to loosen the soil around the pot.

Step-5: Grab and pull

Once the soil is loose enough you can easily get the plant out of the put. Do this by holding onto the stem of the plant and pulling it out gently. Do not pull too hard or you will have a broken plant.

Step-6: Dust the roots

Once you have the plant out of the soil it is important to dust off soil from the roots. As the division happens at the roots it will give you a clear view of the portion you need to work with.

Step-7: Identify a crown

Once the roots are clean it will be easier to identify crowns. These are mini-plants that need to be divided.

Step-8: Cut off crowns.

Once you have identified the crowns you can separate them from the mother plant using a pair of scissors or by pulling them apart. Be careful not to damage the roots while doing so.

Step-9: Lay them aside

Instead of potting as soon as you cut the crowns. You can set them aside and work with the mother plant first. After you have cut the crowns repot the mother plant and then come back to the saplings.

Step-10: Pot the saplings.

This is the final step where the sapling or saplings get their own pot with a new potting mix.
