Habit: Small to large evergreen plants that produce a rosette of narrowly to broadly lanceolate to elliptic leaves that are usually green to dark green but can also be variegated with green and white or green and yellowish-green. The inflorescences are produced out of the centre of the leaf rosette and grow taller than the leaves topped by the typical aroid flower with a white or rarely green spathe that may be sweetly fragrant or not.
Temperature: Plants grow best between 20 to 25ᐤ C but are tolerant of temperatures between 5 to 37ᐤ. Avoid placing plants in windy or drafty locations which can lead to less attractive plants as the leaves can get tattered.
Light Exposure: Plants will grow well in medium to bright, indirect light but are capable of surviving in low light locations in which the plants will grow very slowly. Plants with darker green leaves are able to withstand lower light locations but regardless of, all plants will benefit from rotating a quarter to a half each week to keep plants balanced and avoiding them becoming lopsided.
Watering: Peace Lilies like a moist growing medium but not soggy; water only when the top 3 to 5 cm of soil feels dry to the touch. Always check the soil moisture first but as a rule of thumb watering once a week in the rainy season, once every two or three weeks in the cold dry season and usually twice a week in the hot dry season. In addition, regularly misting the leaves in the hot dry season will help keep the foliage looking great.
Fertilising: Plants need to be fertilised with a well balanced fertiliser at half strength only once per month. Plants can be damaged by over fertilizing so one must be careful not to feed plants too much or too often as prescribed.
Pruning/Repotting: Remove yellowing and dead leaves and spent flower stalks as necessary. Peace Lilies can withstand a moderate level of being root bound but will need to be repotted when plants begin to wilt more frequently even after being watered or if offsets have started to crowd out the mother plant. In such a case, separating out the offsets and potting them up separately increases the vigour of the mother plant.
Pests/Diseases: Mealybugs, aphids, spider mite and scale are all pests that attack the leaves. While a few fungal pathogens can cause leaf spot and blight issues as well as root rot and a virus can cause a mosaic virus of the leaves.
