The important thing is to care enough about it to want to help it restore its original healthy condition. This is why you need to stay tuned and read carefully what I’m about to tell you.

Peace Lily Flowers Turning Brown or Black – The Main Causes

Brown or Black Peace Lily Flowers - The Main Causes

Now that you got the idea of what we are going to deal with, it is going to be easier for all of us to tackle the main issue here – peace lily brown or black tips on flowers.

Do bear in mind that we are only dealing with peace lily brown flowers here, while peace lily brownleaves are a matter for a different kind of discussion.

Now that we have established our main point of concern – browning or blackening of peace lily flowers – let’s shift the focus to the main culprits here.

1. The environmental impact

Even though we like to believe that it doesn’t matter where we keep our flowering plants, we might want to think again.

I kept my pink violets at the partial shade, and do you know what happened? Well, they almost stopped flowering even though it was their flowering time.

Thanks to my poor violets, I learned my lesson (obviously, the hard way!) and decided to always pay attention to where I keep my house plants.

The final result was that once I got my peace lily, I knew what needs to be done if I want to have luscious flowers for as long as possible.

So, these would be the details to bear in mind when choosing the perfect environmental conditions for your plant.

1.1 The spot

To avoid your peace lily flower turning brown, you have to choose a proper spot. Bear in mind that direct sunlight exposure is a no-no!

Yes, yes to bright and airy spaces, but nothing too strong that will lead to your peace lily turning brown or black.

The ideal setting for your plant will be space with dappled and slightly dim light. Or, to be more precise, you can choose an eastward facing window. This will give plenty of sunlight in the morning when the sun is still not too strong and later in the day it will provide just the right amount of sunlight.

This way, you will save your lovely peace lily flowers from changing color from magnificent white to unsightly brown or black.

Although sometimes a northern window can also do the job, try to stick with the windows facing east.

Another point to pay attention to when choosing a spot for your lily is to avoid places with a cold draft. 

Also, keep them at a place where they won’t be reached by kids or pets (it’s toxic!). This will indirectly cause the leaves to turn brown or green since it can disturb the plant in total.

1.2 The temperature

Note that the temperature requirement is a rather important precondition in creating a perfect setting for your loved plants.

And, how to know what’s best for your plant?

Well, just check its origins.

When it comes to peace lily, it’s native to tropical areas so when kept indoors it will thrive in slightly “warmer” conditions.

You can set the temperature in your household, office, or wherever that you keep it, at 70°F to optimize the temperature conditions.

Still, note that you can go slightly lower than this, but whatever you do, don’t let the temperature go below 60°F.

1.3 The humidity

Again, remember this is an originally tropical plant.

This is why it likes to be kept in a humid environment. Keeping it in dry areas will lead to your peace lily leaves turning black and the flowers too!

2. The lack of proper care can lead to peace lily leaves turning black or brown

Our second group of causes that can cause the change of color from white to black or brown can easily be summed up under the common title – the lack of proper care.

All living things need to be nurtured and cared for. Why would it be different for peace lily?

Here’s what this means in practice.

2.1. Soil

Proper care for any house plant starts by selecting the proper type of soil. While you might think that any soil will do just fine, typically you need to be pickier than that.

If you thought of giving a chance to any commercial mix, you might want to reconsider that.

Why don’t you try peat potting mix instead; the one with compost and bark perlite?

This kind of soil will provide optimum nutrition and will play an important role in keeping the proper moisture levels, i.e. neither too dry nor too wet.

2.2 Watering

Are peace lily flowers turning brown?

Hmm, are you sure you watered your peace lily properly?

And, what does properly even mean, by the way?

First of all, don’t be misled by the notion of how flowering plants need more water.

Yes, peace lily needs water; however, you’d rather be moderate instead of showering your plants with abundant water.

You might well do it a favor if you keep it without any water for a few days and only water when its leaves start drooping.

Still, the most important fact when it comes to watering is that you must avoid tap water. Obviously, tap water contains a bit more than hydrogen and oxygen, most notably chlorine and fluoride. The latter can be detrimental in such a way that includes the blackening or browning of the flowers on your peace lily.

Finally, you can mist the leaves from time to time just to create better humidity conditions and make the foliage greener and lusher.

2.3 Fertilizing

Another inevitable step in proper care for our peace lily that will most certainly help you prevent the change of color in flowers.

As for fertilizing, the more is not always the merrier.

Again, you need to be moderate as too much fertilizer can lead to over-saturation with nutrients leading to browning or blackening tips of peace lily flowers.

Avoid fertilizing during the dormant season and start adding fertilizer as soon as the winter is nearly over.

After that, you’re good to go fertilizing every six weeks.

2.4 Repotting and Pruning

A proper care schedule for your peace lily must naturally include repotting and pruning.

When it comes to repotting, you know that the idea behind is to repot once you figure out your pot is way too small to hold the roots inside.

Typically, repotting is best done in spring, before the flowering season which gives enough time for the peace lily to recover.

Still, this does not necessarily mean that you must repot every year.

Another reason that should talk you out of frequent repotting is stress. You do not want to cause that. Doing it way too often will do more harm than good to your peace lily.

So, assess and evaluate.

See if it really needs to be transferred to a larger container.

As for pruning, you need to know that this contributes to the general well-being of your lily.

Do it carefully and remove all of your peace lily black leaves or brown, and the flowers too.

Once they go brown, or black, they ain’t coming back!

When I said carefully, I meant that the texture of the flower, once withered, remains kind of wiry so you should make sure not to hurt yourself in the process of removing it.

3. The influence of aging

The equivalent of this would be to say “It died of natural causes”. Or, to be a bit less morbid, I’d rather say that it followed a natural course of events and eventually withered and died.

One of the causes for your leaves to turn brown or black is also aging. We are aware that nothing lasts forever. Accordingly, neither will your peace lily flower.

From the moment it fully blossoms, your peace lily flower only has a limited life span before it dies. The process of dying is clearly indicated by the fact that the flower starts changing color. It will start by showing brown tips. 

Sadly, the brown color will slowly expand all over the flower and once it has covered it in full, it’s time to cut your leaf since it’s no longer among the living.

By the way, at what point do you know that the flower turned brown because of aging and not because of something else?

Basically, the question is 

What Is the Expected Lifespan of a Peace Lily Flower?

Peace Lily Flower Lifespan

Even though I am aware we want long-lasting flowers on any plant we grow indoors, peace lily might be a slight disappointment here. After fully developed, the peace lily flowers only last for 10 days or so.

I know it’s not much, but enjoy it while it lasts.

Still, don’t be too sad about the death of a single flower. Peace lily can grow multiple flowers at the same time so you will find the needed comfort.

Pro Tip: As a true plant enthusiast, I couldn’t help it but search and investigate different ways of keeping my plants as healthier as possible. This is why I will share with you the following secret.

Give a shot to gibberellic acid. This little friend does wonders for your peace lily flowers making them grow at a faster rate and stick a bit longer.

Still, don’t expect the impossible. We still haven’t found the cure for death.


1. Is it a good idea to use coffee grounds to help your peace lilies to grow?

This is a trick you can easily try on your peace lily. Adding coffee grounds will bring multiple benefits to your peace lilies starting from aided nutrition, healthier looks, lowering the pH value of the soil, and yes! reversing the browning process that started way too soon.

Naturally, you can add it to soils as you would add some fertilizer. However, don’t overdo it!

One pot of coffee grounds will be just enough, applied once a month. If this isn’t working, then increase the quantity and always bear in mind that every peace lily is different and has different requirements.
Observe your plant and draw conclusions from that.

2. Can you cut off black or brown peace lily flowers?

Yes, you can!

In case you decide to do that once the flower has started showing indications of browning, I suggest you use the properly clean shears (to avoid potential infections). Cutting/pinching by hand is not recommended since it can harm the rest of the plant.

It would be best to cut all the way down to the stem since there is no point to keep it when the flower is dead.

3. What does an overwatered peace lily look like?

Hmmm, it looks terrible, that’s is how it looks!

The leaves seem cooked, drooping, with mere signs of or yellowing throughout.

And, since we are focusing on the flowers when your peace lily is overwatered, the flowers will show brown tips.

So, to sum up, overwatering is a no-no!


And, that would be all folks!

Now that you know all the reasons for your peace lily flowers turning black, you can act accordingly to prevent this from happening.
