Besides they are easy to take care of, Peace Lilies are fast-growing plants and their graphic aspect is very decorative. Its neutral color goes well with all types of pots and it’s also considered as a depolluting plant.

Peace lily plantation
In our climates, Peace lily is used as a houseplant inside our houses and our apartments. It grows well when temperatures are around 65-85°F.
Plant it in spring, during the vegetative awakening period. You can also replant it later, until fall, but it may take longer to restart:
- Put it in a good-sized pot and plant it in special potting soil for indoor plants or flowering plants.
- It is necessary to repot Peace lily in the spring every 2 to 3 years (every year would be better). To avoid substrate compaction, you can add a handful of pozzolana to the potting soil.
- Finally, place the pot on a bed of clay balls or small pebbles that you will keep constantly moist; the evaporation of this water allows the foliage to regain the humid climate of its natural environment.
The Spathiphyllum needs a strong light, although it can grow in half shade. On the other hand, avoid exposing your pot of Peace lily to direct sun which can cause burns on its leaves. In order to have a healthy Peace lily with bright green foliage, place it near a window. In winter, if there is a lack of light, move the pot to a brighter place.

The part of the foliage receiving the light develops more harmoniously than that in the shade. For a nice balance, turn the pot from time to time.
Peace lily Care
Watering Peace lily plant
The spathiphyllum needs regular watering. It is important that the potting soil has time to dry on the surface before watering. During the flowering period, it is recommended to fertilize the houseplant regularly.
The frequency of watering varies according to the seasons and the seasonal needs of the plant.
In spring and summer
It must be regular but limited (2-3 irrigations / week):
- There is no need to flood the plant as its roots may not appreciate.
- So water generously but not excessively and wait until the soil is dry on the surface to water again.
- Since the foliage needs certain humidity, do not hesitate to spray non-calcareous water on it regularly.
- Finally, every 2 to 3 weeks, add liquid fertilizer to stimulate flowering and ensure good growth for the plant.
If you forget to water your Spathiphyllum, you will see its leaves gradually yielding. It is a good sign to identify that the plant needs water. As soon as you water it, its leaves will straighten almost instantly, it’s amazing!
Peace lilies are sensitive to Chlorine in the tap water; let the water sit for 24h to dissipate harmful chemicals.
From fall to winter
You have to reduce watering as you go along and stop adding fertilizer or organic matter; the houseplant comes to winter rest and needs to be quieter.
It will be much better in a slightly cool room or at the edge of a north-facing window from October to March.
How and when to repot Peace lily?
Repot your Spathiphyllum once a year, in the spring, when the roots emerge from the bottom of the pot and on the surface. In the first years, the plant doubles in size each year; repot it in a slightly larger pot in a fresh and well-draining potting soil.
Don’t forget to water your Peace lily a few hours before repotting and to water lightly after repotting to settle the new substrate.
The larger the plant, the more flowers it produces, so don’t hesitate to repot it every year to get the most out of it.
Pruning and maintaining Spathiphyllum
Pruning is not really necessary; just remove the dry or damaged leaves and dead flowers as you go, cutting them at the base with clean scissors.
To get beautiful shiny leaves, you can dust your Spathiphyllum with a damp sponge dipped in light lemon water. To be done once a week.
How to revive Peace lily?
If you have not watered your Spathiphyllum for several weeks (forgetting, returning from vacation …), and you see it all soft and weak, the leaves drooping and almost touching the ground … no panic! Spathiphyllum, despite its high need for water, is a very resistant plant.
Place the pot in a bucket full of water and allow the plant to rehydrate quietly for several hours. There is a good chance that the leaves will straighten slowly and your Spathiphyllum will start again.
Peace lily pests and diseases
Peace lily is little affected by diseases. It is more the errors and negligence of maintenance which cause problems with this plant.
- If the tips of the leaves turn brown or the leaves turn yellow, this is most likely caused by excess water.
- If brown spots appear on the leaves, the plant may have received too much fertilizer, unless they are burned from the direct sun.
- Soft, drooping leaves usually indicate that the plant is lacking in water.
- A lack of flowering can be caused by a lack of light unless fertilization is insufficient or the plant pot is too large.
Peace lily can be attacked by aphids or red spiders:
If the leaves are deformed and sticky, it is the work of aphids which suck the sap of the plant. You can get rid of aphids simply by wiping your houseplant leaves. If the plant is heavily attacked, you may use Neem oil or insecticidal soaps to have a better result.
Red spiders Attack
If houseplant’s leaves are yellowing and drooping, these are the signs indicating the presence of red spiders. Increase humidity by misting all the leaves and stems repeatedly with non-calcareous water. Red spiders do not like humidity; several successive sprays of water can be enough to stop a weak infestation.
Horticultural oils and insecticidal soaps also work to get rid of red spiders.
How to Propagate a Peace lily
The easiest way to propagate Peace lily is through splitting leaves. Theoretically, the division of perennials can be carried out all year round but prefer spring; during the spring, your houseplant will restart quickly while in winter it may take several weeks.
At adult size, by dividing once every 2 or 3 years, your Spathiphyllum will regain strength and you will be able to assure it a good longevity.
- Remove the mother houseplant from the pot then gently remove the potting soil with the tip of a pen to ventilate the roots (a ballpoint pen or a paper-pencil is ideal).
- Spot the parts where the foliage is connected to the roots, then gently separate the roots and stems.
- Repot the two parts with potting soil for evergreens (well-draining mix).
