Why Is Your Peace Lily Not Flowering?

Unfortunately, there are a number of different reasons that your peace lily might not be flowering. So you’re going to need to figure out for yourself the problem with your peace lilies. So here are all the different causes of a non-flowering peace lily!

They’re Not Getting Enough Light

One of the main reasons that your peace lily may not bloom is because they’re simply not getting enough light. Just like any plant, without enough light, they won’t be able to photosynthesize, and then they simply won’t have enough energy to bloom.

They’re Getting Too Much Light

One of the hardest parts about taking care of peace lilies is trying to get the lighting just right. Because unfortunately, it’s just as easy to give your peace lily both too much light and not enough light. If they’re getting too much light, then it’s going to potentially burn the leaves and stress your plants.

They’re Not Getting Enough Water

It may be the case that your peace lily isn’t getting enough water. If the soil you’re growing your peace lily in is dry, then it’s going to be a lot harder for your peace lily to translocate and absorb nutrients.

They’re Getting Too Much Water

Just like with light, you need to make sure that your peace lily isn’t getting too much or too little water. When your peace lily’s soil is too moist, then it won’t flower as the roots need aeration to function properly. In fact, too much water can often result in root rot.

The pH Of The Soil Isn’t Right

Peace lilies love soil that is slightly acidic. Ideally, you want a pH that is between 5.0 – 6.5. Anything more or less than this and your peace lily won’t be able to absorb nutrients as well. And the further out of the range it gets, the worse the absorption of nutrients will be.

The Temperature Isn’t Right

Another reason that your peace lily isn’t blooming or flowering is because you’re not keeping them at the right temperature. The ideal temperature for peace lilies is anything between 68 and 85°F. When the temperature is too high, then your peace lily is going to lose too much water, and when it’s too low, then it will try to conserve more energy and stop the production of flowers.

They’re Not Old Enough

When you bought your peace lily, it may have come with a flower already blooming on it. But this doesn’t mean it’s old enough. Commercial growers often use gibberellic acid to induce blooming in peace lilies. However, much like steroids, once your peace lily stops receiving it, they’ll need to reach maturity before they’re able to bloom again.

They’re Too Old

Once your peace lily becomes too old, then it’s unlikely they will bloom anymore. A peace lily lives for 3-5 years on average, so if your peace lily is near the end of its lifespan, it’s unlikely it will produce any more flowers.

It’s Not Humid Enough

It can sometimes be the case that the humidity in the room isn’t high enough for peace lilies. Remember, peace lilies are from tropical rainforests, so they like they need a good amount of humidity. Without it, they may begin to lose water through their leaves.

Not Enough Nutrition In The Soil

It may also be the case that your peace lily isn’t getting enough nutrition. However, fortunately, this isn’t too likely, because peace lilies don’t need too much nutrients to survive. In fact, it’s often the case that peace lilies get a nutrient burn from too much nutrients.

They’ve Already Bloomed

While it is possible for your peace lily to bloom multiple times in a year, it is quite rare, so if your peace lily has already bloomed once or twice in the last year, then it’s unlikely it’s going to bloom again.

They’ve Outgrown Their Pot

And lastly, it’s also possible that your peace lily has outgrown its pot. If this is the case, you’ll notice roots starting to poke out of the drainage hole and sometimes even out of the top of the soil.

When a peace lily is this big, it is going to reduce the amount of nutrients it can absorb, and it will also need more nutrients than is currently available in the pot.

How To Get Your Peace Lily To Bloom

Fortunately, while there are a lot of reasons that your peace lily may not bloom, there are also a lot of solutions and ways you can get your peace lily to bloom as well!

Get The Light Right

This is probably one of the most important things you can do in order to get your peace lily to blossom. You need to make sure they’re neither getting too much nor too little light. So try to find an area where the sunlight isn’t too powerful.

If you’re not sure how much sunlight is too much, try placing your hand in the area you plan on keeping your peace lily. If you notice that you can still see your shadow, but it isn’t overly opaque or barely noticeable, then this is probably a great spot for your peace lily!

Try A Bright Indoor Light

If you can’t find a good spot in sunlight (which is actually quite common), then you can also try using a bright indoor light as well. You can get LED lights that are specifically designed for growing plants, so these can be a great alternative to natural sunlight!

Give Them The Right Amount Of Water

You should also ensure you’re giving them the right amount of water. Not too much and not too little. Fortunately, there’s a very easy way to figure this out. All you have to do is poke your finger into the soil. If you notice the soil is dry at the first knuckle, then your peace lily will need watering. However, if you notice that the soil is still moist at the first knuckle, then they shouldn’t need watering just yet.

Keep The Temperature Perfect

As previously mentioned, you need to make sure you’re keeping the temperature between 68 and 85°. So whatever room you place your peace lily in, make sure it can be maintained at this temperature.

While the temperature can drop at night, you also want to make sure that it doesn’t fluctuate too wildly. For example, leaving your peace lily by an open window or too close to a radiator can stop it from blooming properly.

Make Sure It’s Humid Enough

You also need to make sure the environment your peace lily is growing in is humid enough as well. There are three main ways you can do this.

  • The easiest way is to mist them 2-3 times a week. This is probably the easiest ways, and it ensures your peace lily won’t lose too much water from evaporation through the leaves.
  • You can also buy a humidifier and place it near your peace lily. This is particularly good if you have multiple flowers that need a humid atmosphere
  • Lastly, you can group any tropical plants you have together. When you do this, they’re going to create their own mini atmosphere that remains humid!

Fertilize Them During The Growing Season

To really encourage your peace lilies to grow, you should fertilize them during spring to early summer as well. You only need to fertilize them about once a month, and you should avoid using full-strength fertilizer as well. Instead, water it down, so it’s only about 25% of the strength.

As well as this, you can also use some household waste such as coffee grounds as fertilizer too!

Repot Them

If you think that your peace lily being too big for the pot is preventing them from flowering, then, of course, that means it’s time to repot them! When repotting your peace lily, you should only pick a pot that is 1 or 2 inches bigger than the pot you currently have them in.

When you put them in a pot that is too big for them, then it’s going to be harder for them to absorb enough nutrients and is it will be spread too far through the soil.

Use The Right Kind Of Water

You should also make sure you’re giving your peace lily the right kind of water. Chemicals such as chlorine are particularly harmful to peace lilies, but other chemicals and metals in the water are damaging too.

So you need to make sure that before you’re giving your peace lily water from the tap, you’re letting it sit out for at least 24 hours so all the chemicals can dissipate. Failing this, you can also use rainwater to water them!


Here are some more commonly asked questions about getting your peace lily to bloom!

Can You Make A Peace Lily Flower Again?

It’s entirely possible for your peace lily to flower twice a year or have multiple flowers at once. The best way to increase the chances of your peace lily flowering more than once in a year is to provide the perfect conditions for them and remove flower heads as soon as they die!

Can Peace Lilies Bloom All Year?

It’s not natural for peace lilies to bloom all year, only during early spring to summer and then again in fall. However, when you use gibberellic acid on your peace lily, they’ll bloom all year round; however, this isn’t recommended for home growers, as it can damage your peace lilies.

Why Are Your Peace Lily Flowers Green?

When your peace lilies first begin to bloom, it’s common for them to be tinged green. However, if you notice once they’ve reached their full bloom that they’re still green, then it could be that you’ve overfertilized them or because they’ve received too much sunlight.

What Should You Do With Dead Peace Lily Blooms?
