Spathiphyllum wallisii Care Indoors

Peace Lily (Spathiphyllum wallisii) blooms in bright, indirect light away from direct sunlight, average warmth, moderately humid conditions and moderately moist, fertile, well-drained soil coupled with monthly feeding during the growing season.

Spathiphyllum wallisii only requires repotting when pot-bound as it blooms best when the roots are confined. Pruning is necessary to keep the plant neat as well as discourage pest and disease infestations. Keep reading for more on these growing conditions and how to achieve them.

Water Peace Lily liberally during the growing season while allowing the top 2-3 in. of soil to dry out between waterings to maintain the soil moderately moist.

Decrease watering during the cold season to keep the soil slightly moist as growth is minimal at this time and so the plant will not require a lot of water. However, do not allow the soil to dry out completely.

Use room temperature water to water the Peace Lily as cold water can shock this tropical plant resulting in reduced growth.

Ensure that the water is chlorine-free as White sails is sensitive to chlorine and other chemicals dissolved in water.

To avoid getting soggy soil which can lead to root-rot and death of the plant, ascertain that the pot has a drainage hole.

Light Requirements

Peace Lily grows best in bright, indirect light (partial shade). Keep it away from direct sunshine to avoid scorching the leaves.

White sails can also be grown under grow lights where the natural light is inadequate. Take a look at these full spectrum grow lights available on Amazon.

Temperature and Humidity

Peace Lily thrives in average warmth within the range of 18-260C. A room temperature that is comfortable for you is ideal for the plant.

Keep the Spathe Flower away from cold and hot drafts to prevent sudden changes in temperature as they can cause reduced growth.

Average room humidity is adequate for Peace Lily. However, if the air is too dry, the plant may develop brown leaf tips and edges.

To increase humidity, set the pot on a wet pebble tray or use a cool mist humidifier. Check out these techniques on how to raise humidity for houseplants.

Regularly clean the leaves by damp-wiping with a soft cloth to get rid of dust and reduce infestation by pests.

Potting Mix

Most multi-purpose potting mixes are ideal for Spathe Flower. Buy quality multi-purpose potting mix online from Amazon.


Feed Spathiphyllum wallisii monthly during the growing season with a phosphorous-rich, water-soluble fertilizer to encourage flowering. Withhold feeding during the cold season as growth is minimal at this time.

Peace Lily is sensitive to chemicals that may be accumulated in the soil therefore, regularly flush out excess chemical deposits from the soil by running a stream of water through the soil until water comes out through the drainage hole. Let the stream of water run for a few minutes.


Keep Peace Lily pot-bound to promote flowering and repot during the growing period only when it has outgrown its current pot.

Repot into a pot that is only 1 size larger than the current one and ensure that the pot has a drainage hole to prevent the soil from getting soggy. Check out these Pots with Multi Mesh Drainage Holes on Amazon.

During repotting, divide large Peace Lily plants to allow adequate room for growth in the new pot.

Cut through the rhizomes with a sharp sterile knife and pot the sections in individual pots.

Ensure each of the pot for the sections has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot disease and eventual death of the sections.


Pruning Peace Lily is easy as it involves removal of dead leaves to keep the plant neat and also minimize pest and disease infestations.

Once the blooms are spent, cut them off as close to the base as possible to maintain the plant neat and tidy.


Peace Lily (Spathiphyllum wallisii) propagation can be done at the beginning of the growing season by division of mature plants.

How to propagate Peace Lily by plant division

Water the Peace Lily thoroughly at least 1 day before to make it easier to divide and also hasten establishment. A well hydrated plant suffers less shock and takes a shorter time to take root.

Take the plant out of its pot and carefully divide the rhizome into several sections while ensuring that each division has at least 2 leaves and some roots.

Pot the sections into individual pots in moist free-draining soil that is rich in organic matter.

Water soil thoroughly and place the set up in a warm, well-lit place away from direct sunlight. Maintain the soil consistently moist thorough out but not soggy.

The sections may wilt slightly due to the repotting shock but they will recover with time.

Allow the Spathiphyllum wallisii sections adequate time to be well established before moving it to its display position and beginning routine care.
