A Peace Lily is a beautiful addition to any home. Not only do they look great, but they are also straightforward to care for! This blog post will discuss how to get your Peace Lily to bloom and how long it will stay in bloom.

We will also give you some tips on how to keep your plant looking healthy throughout the year.

Peace lilies are one of the most popular indoor plants because they're relatively easy to care for and make a significant impact in any space. One of the best things about Peace Lilies is that they typically bloom twice a year, once in spring and once in Autumn. Once bloomed, the flower can last anywhere between 1-2 months. However, some hybrid varieties can rebloom.

What is a Peace Lily?

Peace Lilies (spathiphyllum spp) are beautiful house plants native to tropical regions of Asia and the Americas.

The plant gets its name from its large, white spathes (flowers), which resemble flying flags of peace. The spathe is a modified leaf called a bract. As the flower ages, the spathe will change colour to green.

Peace lilies are relatively easy to care for and make an excellent addition to any home or office.

The plants prefer warm, humid conditions, and Peace Lilies should be watered regularly. Peace lilies also benefit from being misted with water, and they should be fertilised every two to four weeks during the growing season.

Peace lilies are not true lilies and are a member of the Araceae family, which also includes philodendrons and anthuriums.

How to care for a Peace Lilly?

Although the Peace Lily is tolerant of low light conditions, it will bloom more profusely if given bright indirect light.

Native to tropical regions, Peace Lilies prefer warm temperatures and high humidity levels. I have mine in the bathroom, and it seems to love it there!

Allow the top inch of soil to dry out between watering and fertilise monthly during the growing season. When the Peace Lilly is not in bloom, it can be allowed to dry out more frequently.

Lighting:

In general, peace lilies prefer bright, indirect light. They will tolerate some direct sunlight, but too much sun can scorch and burn the leaves.

If you notice you are getting yellow leaves, it is likely, that it is not getting much light, so it's a good idea to move the plant to a brighter spot and provide some protection from direct sunlight. 

An east-facing window is perfect for a Peace Lily as it will get direct light in the morning and shade from the harsh afternoon sun.

Water:

When it comes to peace lilies, more isn't always better.

This popular houseplant is known for surviving in low-light conditions and tolerating periods of neglect. However, peace lilies are also susceptible to root rot, and overwatering is one of the leading causes of this problem.

So, how much water does a peace lily need? As a general rule, peace lilies should be watered once a week, with a thorough soaking, so that you can see water coming out from the drainage holes in the base of the plant pot, and then allowing the top inch of soil to dry out before watering again.

During the winter months, when growth is slower, you may need to water less frequently. If you're unsure whether your plant needs water, stick your finger in the soil or use a moisture meter. If it feels dry several inches down, it's time to water.

Also, Peace Lilies can be a little dramatic 🎭. When they need watering, they will wilt and flop!

Avoid using tap water when watering Peace Lillies as they can be sensitive to fluoride, so it is essential to use filtered or distilled water.

Temperature:

The peace lily is a tropical plant that thrives in warm, humid conditions. Its right temperature is between 70-75°F (21-24°C) during spring and summer and 60-65°F (15.5-18°C) during the winter month as it does not tolerate chilly weather well.

The peace lily is often used as a houseplant because it is so well-suited to indoor conditions as it doesn't like cold temperatures.

If the temperature dips too low, the peace lily leaves will begin to turn brown and wilt. However, if the plant is kept in a warm, humid environment, it will thrive and produce beautiful white flowers.

Fertiliser:

Fertiliser is an integral part of maintaining a healthy peace lily. The best time to fertilise your peace lily is in the spring or early summer when the plant is just starting to show new plant growth.

You can apply a balanced houseplant fertiliser (I use For Peat's Sake's Hungry Plants fertiliser and love it!) or choose a fertiliser specifically designed for flowering plants. Either way, follow the package's directions, as too much fertiliser can damage the plant.

Once the plant has finished blooming, you can reduce the fertiliser you use. In Autumn, stop using fertiliser altogether so the plant can go dormant for the winter.

Can Peace Lilies flower all year round?

While most plants have a specific season for blooming, Peace Lilies are one type of plant that can bloom all year round with the proper care.

Indoor Peace Lilies can bloom multiple times yearly if provided with enough light and water. To encourage blooming, they like to dry out between waterings and don't like continuously moist soil.

Additionally, fertiliser can be used to give the plant an extra boost. With proper care, peace lilies can continuously display beautiful white flowers.

Garden Centres

If you have ever bought a Peace Lily from a garden centre, you may have noticed that it often flowers well outside the typical flowering season.

The reason for this is a little-known plant hormone called gibberellic acid. Commercial growers use this hormone to encourage young plants to flower more often than they usually would.

When Gibberellic acid is watered onto the potting mix, the young plant will start to flower within two months, even though the flowering season is well and truly past.

What do you do when peace lilies have finished flowering?

After a peace lily has finished flowering, it is essential to remove the flower stalk carefully. Removal can be done with your fingers or with a sharp pair of scissors.

Once the flower stalk has been removed, you should trim the leaves that have yellowed or died. This will help the plant to focus its energy on new growth.

Finally, it is crucial to fertilise peace lilies regularly to ensure they continue to thrive. A slow-release fertiliser can be applied every few months, or a weak liquid fertiliser can be used weekly during the growing season.

Peace lily propagation through division

One of the easiest ways to propagate a peace lily is by division. The process is simple and requires a sharp knife and a pot with well-drained soil.

First, carefully remove the plant from its pot.

Next, use the knife to divide the root ball into two or three sections. Be sure to include a few healthy roots in each section.

Once the plant has been divided, replant each section in its pot with drainage holes at the bottom of the pot and water generously.

FAQ:

Q: Why do peace lilies stop flowering?

A: Peace lilies can stop flowering for many causes, but the most common reason includes poor watering habits, lack of fertilisation, or low light levels.
Or it could be a young Peace Lily plant with Gibberellic acid to promote flowering. Once it has grown a bit bigger, it should start flowering as usual.

Q: How often should I water my peace lily?

A: Peace lilies should be watered about once a week or when the soil feels dry to the touch. It is important not to overwater or underwater the plant, as this can cause leaves to turn brown and wilt.

Q: How do I make my peace lily bloom?

A: To encourage blooming, keeping the soil moist but not soggy is essential. With proper care, peace lilies can continuously display beautiful white flowers. Additionally, fertiliser can be used to give the plant an extra boost.

Q: How long does a peace lily bloom last?

A: Peace lilies flowers typically bloom for about six to eight weeks. However, with proper care, they can bloom multiple times per year.

And Finally…

It can be challenging to keep a Peace Lily healthy and blooming constantly. Here are some tips to help you out:

First, make sure you are watering it correctly. The best time to water a Peace Lily is in the morning, and you should water it until the soil is wet but not drenched. Be careful not to overwater it, or you might have root rot.

If you live in a warm climate, your Peace Lily may need to be watered more often than in a cooler climate. Check the soil regularly and water it when it feels dry.

If your Peace Lily isn't blooming, you can do a few things to help it along. One thing you can try is moving it to a sunny spot. You can also fertilise it with a balanced fertiliser every two weeks.

And finally, if all else fails, you can try transplanting it into fresh soil.

Keeping your Peace Lily healthy and blooming is definitely worth the effort!

  1. I have a big problem with my flower. Once it is completely green, and often catches some of its leaves turning yellow. Or some green leaves at the very tip are withering at the tips. I don’t know what’s wrong with him and how to make him always look beautiful. Do they constantly need to be repotted into larger pots, or does it eventually stop growing because it takes up the entire pot from time to time and I repot it into a larger one?

    1. With Peace Lilies, can be a bit dramatic, make sure you keep it moist, but not soaking wet, I would invest in a moisture meter so you can see when it needs another watering. Also, if you haven’t repotted in awhile give it some food, I prefer a liquid fertiliser that I can add to the water when it’s ready for a drink. Hope that helps 🙂
