Why Is My Peace Lily Dying?

Peace lily, also known as Spathiphyllum is an evergreen tropical plant. It can easily be spotted on the floor of rain forests and other tree-concentrated areas. With time, the plant has become readily available in the market in numerous varieties. Unfortunately, peace lilies can be a bit tricky to take care of.

If your peace lily is dying, there could be several problems that you must identify and solve. These can vary according to the conditions you keep your plant in. The plant needs plenty of sunlight and a moderate to warm temperature.

Moreover, you must ensure you provide a sufficient water supply that can be maintained without any disruptions. In case you notice your plant to be losing health, make sure you check out the pot size comparative to your plant size.

A mismatched pot can hinder your peace lily’s growth in many ways. Keeping these and other factors balanced is essential for the growth of peace lilies.

Causes Of A Dying Peace Lily

Light Intensity

Peace lilies prefer bright indirect light over direct sunlight exposure. Therefore, if you keep your peace lily in direct sunlight, it can cause your plant to lose leaves.

Although a little morning sunlight exposure can be healthy, too much of it can end up burning your plant’s delicate leaves. Peace lilies require constant indirect light and thus, if your peace lily is dying, check if you are over-exposing it to direct sunlight.


You can always protect your dying peace lily by ensuring that you provide it with the perfect amount of light.

Although sunlight is the major lifeline of a lily, you must ensure that you don’t let your lily be exposed to excessive heat or direct sunlight. This can be achieved by keeping it in a shade where it is safe from direct heat exposure.

Optimum Temperature

Peace lilies love it warm. Keeping a close check on the optimum temperature is essential in their growth. It can have a great impact on how your lily ends up a few months later. Trying different temperatures can be helpful depending on other factors.

However, a temperature range of around 65F-85F can end up producing impressive results and even flowers!


Temperature can be a deciding factor when it comes to developing a healthy plant. Carefully monitor the temperature you are keeping your peace lily in. If the temperature is too high and doesn’t fall in the optimum temperate range, take necessary measures to ensure a constant optimum temperature.

These include creating an environment where your peace lily feels like home. For example, a tinted sunroom would work just fine as the tint would let the sufficient amount of light through to your peace lily. Therefore, fulfilling the requirements of a constant indirect supply of sunlight.


Peace lilies and water go well together. If you notice stunted or no growth in your peace lily, check out the water balance you are following. These plants enjoy a constant moisture presence. Letting them dry out can quickly cause them to wilt and collapse in no time.

Moreover, the lack of water can also result in the growth of brown tips to your leaves. Note that this can also occur if you waterlog your pot. Therefore, even if you have been watering your peace lily less than required, you must increase the water supply, and it will recover quickly.

But make sure you develop a periodic and balanced water supply for your plant. Too much repetition of the wilting-recovering process may lead to a weaker plant in the longer run.


Water is life for plants is a well-established fact. Therefore, any improper watering patterns may have a significant impact on the growth of your peace lily. This is where you must check out on your watering routines and come up with a solution.

Provide your peace lily with sufficient water. This can be done by developing a stable routine and watering patterns. You can keep a record in hardcopy for the amount of water you feed your peace lily and its growth. Graphical representation of the data can be of great help.

Use Of Fertilizers

Like any plant, fertilizers can pour in the missing life from a plant. The lack of nutrients and essential components in the growth of your peace lily can be countered by the use of fertilizers. The optimum time for fertilizing the soil is in late winter and through early fall.

However, make sure you don’t overdose your lily on fertilizers. This can damage your plant in the long run as it won’t utilize the entire nutrient intake.


The use of established fertilizers has to be made essential. Visit the nearest nursery to take proper guidance on which fertilizer best works. Finding the perfect fertilizer can be a tricky one.

Improper Or No Cleaning

Cleaning your plant is the most underrated strategy to minimize any risks to its growth. It also maximizes the plant’s health and results in a fresher and stronger plant. When it comes to cleaning your plant, the process can vary from plant to plant.

This is decided by the leaves’ shape that ranges from small to narrow and large or broad. The larger, broader leaves will attract a more considerable amount of dust particles on their surface. Therefore, you must take care of the larger dusty leaves.


To fix the dirt issue, make sure you don’t end up damaging the delicate leaves. It is ideal to use a soft, damp sponge to wipe the dust off the leaves. However, a better way is to put your plant under a tap.

Make sure the water pressure is subtle as you don’t want to damage your peace lily.

This method will also give your plant a moderate water supply as you wash it. Therefore, cleaning can be an essential part of the peace lily maintenance, and when correctly done, it can produce excellent results.

Pot Size (environment)

Apart from light, water, and optimum temperature, a critical factor that decides your peace lily’s growth is the pot size. The pot size must be according to your plant. A pot bigger than your peace lily can cause it to die slowly.

Bigger pot also hinders the proper concentration of the nutrient supply to the plant. On the other hand, a pot too small can be a cause for stunted growth. Smaller pots can result in poor stability as the roots don’t have much space to expand.

Hence, pot size needs to be clearly judged and chosen according to your peace lily size.

However, if you find your pot of the wrong size comparative to your plant dimensions, don’t worry, as the process of repotting can help you get the perfect size pot for your peace lily.

The Best Practice – Repotting

The best practice to grow a perfect peace lily and revive a dying one is repotting. Repotting is a procedure that many people ignore, considering it complicated and risky. You must try repotting your plant if you notice declining health. This starts with loosening the root ball.

Loosening The Root Ball

This requires you to take the plant out of the pot and lose the root ball gently with your bare hands. Make sure you start at the bottom and work sideways.

You must separate as many roots as you can without losing patience. If correctly done, this can have a significant impact after repotting.

Setting Up The New Pot

Once you are done with the loosening of the root ball, you set up your new pot. Make sure you choose a pot slightly different in size than the previous one. Make sure you water your lily an hour before carrying out the repotting. Start by gently placing the plant in the new pot.

Make sure you fill in the soil around the root ball with a potting mixture. Lastly, water the soil in a minute amount before adding more and more soil. This will cause the soil to fit in with your plant’s roots perfectly.

Post Repotting

After successfully repotting your peace lily, let it stay in a shady area for a few days. A little wilting is normal after repotting. Make sure you withhold your fertilizer supply for a few months after repotting, as the lily still needs to settle down in its new home.


While there can be multiple causes for your plant lily’s loss of health, the essential stage is identifying the cause. Once identified, you can always take the necessary steps to bring your plant back to life.

Make sure you keep the environment optimum for your lily to grow to its maximum health. Peace lilies are evergreen plants; therefore, any loss of health can be recovered in most cases.

With a proper roadmap and strategies such as repotting, nothing stops you from saving your dying peace lily.
