When to Water a Peace Lily – 6 Factors to Consider

When to Water a Peace Lily – 6 Factors to Consider

Sharing is caring!


The Peace Lily plant is known for its unique white blooms. Peace Lily is not a demanding plant, but like any other plant, it still requires a certain level of care, and getting the conditions right is key.

To achieve these blooms, the Peace Lily has specific requirements that are not always easy to meet indoors.

Similarly to know when to water your Peace Lily because of fluctuating indoor conditions is not always easy.

When to Water a Peace Lily?

A Peace Lily thrives under an optimal watering schedule. Your Peace Lily needs to be watered according to the temperature, lighting, ventilation, and surrounding humidity levels. But factors related to the size of the pot and the size of the plant also affect how much water your Peace Lily requires as well as the season you are in. Spring and Summer are the main growing seasons where your Peace Lily needs more water compared to Autumn and Winter.


What Time Should You Water Peace Lily?

Your Peace Lily will need water once the top half of the soil has become almost dry. You should make sure that you water your plant before the leaves start to droop.

Water your Peace Lily until you see the water pouring out of the drainage holes. Use well-draining potting soil, so that excess water can easily drain out.

If excess water does not drain out, the roots of your plant will start to rot.


Factors That Impact the Watering Schedule of Your Peace Lily



High-temperature levels will cause your Peace Lily to grow faster, but it will also increase the rate of evaporation.

The higher the evaporation, the faster the soil will dry up and the more often you will have to water your plant.

The other way around, the colder it gets the less water is required. This is why your Peace Lily needs less water in Autumn and Winter and should be watered more frequently in Spring and Summer.

Since Peace Lily is a tropical plant, it needs to be kept at a temperature that is over 60 degrees Fahrenheit (15.5 degrees Celsius).

You should also keep your Peace Lily away from cold windows since low-temperature levels can damage your plant.

Keeping the surrounding at a temperature between 65-85 degrees Fahrenheit (18-30 degrees Celsius) is optimal for your Peace Lily.



The stronger the sunlight is, the more it will affect the temperature around your plant. It will also have an effect on the growth rate of your Peace Lily since they do not grow blooms indoors.

Growth and temperature have a significant effect on your plant’s water requirements. Over-casting weather conditions can lower light for your plant, and indoor temperatures can also drop.

This means your Peace Lily will require less water in these conditions.

You must always keep your Peace Lily out of the afternoon direct sunlight. But keep it close to an area where there is bright, indirect sunlight available.



Increased ventilation in your house can increase the evaporation level of water. This will cause the soil to lose water faster, and the transpiration rate can also increase.

A little bit of ventilation is good for your plant, but you must keep it away from heaters and air-conditioned rooms.

If the ventilation and airflow are increased you will need to water your Peace Lily more frequently.

Lower air circulation will cause less evaporation and therefore you will need to water your Peace Lily less.



Peace Lily loves to be kept in humidity levels that are moderate or high. 60% and more humidity is advisable.

Low humidity levels can cause the leaves to have brown tips, causing your leaves to curl up and droop as well.

The majority of plant owners are unable to keep humidity levels high around indoor plants, which is why watering is affected as well.

Lower humidity levels cause your plant to dry up faster since the transpiration rate increases. Thus, you should try to increase the humidity level around your Peace Lily.

Remember to water your plant often during low humidity levels and try to keep the surrounding humidity level high by using a humidifier.


Pot choice

The larger the pot is, the more soil it has and the slower it will dry out. A mature Peace Lily that is kept in a small pot will use up any water that is available to it.

But a smaller Peace Lily in a large pot will not be able to use up all the water in the soil. Also, remember that the type of pot you choose also determines how often you must water your Peace Lily.

A porous clay pot causes more water to seep out of it and causes the soil to dry up a lot faster.

A plastic or ceramic pot that has been glazed will be more waterproof and can hold more water in the soil. You must have proper drainage holes at the bottom of every pot that you use.

This is because excess water needs to be drained out of the pot so that the soil is not waterlogged.

Peace Lily generally likes pots that are larger than their size and can tolerate being slightly root-bound.

This will help your soil dry out a little faster, so if you have a habit of overwatering, this is a good option for you.

If you let your Peace Lily stay lightly root bound in a larger pot, it creates the perfect scenario for you to soak the soil. Then let it remain like that for a week before you water it again.


Size of The Plant

The size of your Peace Lily also determines how much water it needs. A large plant will need to consume a larger amount of water as compared to the small one.

Thus, once your plant has matured, you cannot provide it with the same amount of water as you once did when it was young.


Frequently Asked Questions about watering a Peace Lily


How do I avoid overwatering my Peace Lily?

It is better to underwater your plant than to overwater since recovering your plant from dehydration is easier. The best is to avoid both. Check if the leaves on your Peace Lily droop slightly before you water your indoor plant again. 


How often should I water my Peace Lily?

You should water your Peace Lily based on how dry the soil is. Water your Peace Lily if your soil is almost dry one inch deep into the potting mix. A general rule is once a week but this heavily depends on the environmental conditions such as temperature, humidity, airflow, potting mix, the pot, the size of the plant and the season.
