Location & Temperature
Spathiphyllum wallisii copes with low light and is suitable for bright to shady places, but should not be placed in the dark.
Direct sun is not tolerated, it can cause the leaves to fade.
Warm locations all year round are ideal, overwintering at 59 °F (15 °C) is possible. Temperatures below does not like Spathiphyllum wallisii for a long time.
The Peace Lily does not require a special substrate and grows well in peat-free mixes for houseplants, potted plants, palms, herbs or vegetables.
Watering & Fertilizing
The soil may dry moderately between waterings, but it should not dry out.
The Peace Lily has no problem with short periods of waterlogging, that is, when there is water in the saucer or planter for a few days. As long as there is at least a two week gap between these soggy periods.
Regular potting soils are not suitable for swamp plants. They rot if left permanently under water, which damages the roots and can cause the plants to die.
In addition to liquid fertilizers, slow-release fertilizers such as sticks, granules or pellets are also suitable for feeding. However, these should be given no earlier than one year after purchase or repotting, as regular substrates are pre-fertilized.
Slow-release fertilizers can be given in spring and summer, and liquid fertilizers can be given monthly from spring through early fall.
How to get Peace Lily to bloom (maybe)
Temperate overwintering at about 59 °F (15 °C) can be helpful for Peace Lilies that are lazy about blooming. During this time, the soil is kept only slightly moist. Once Spathiphyllum wallisii is back to warm conditions, it receives enough water so that the soil is soaking wet.
However, not all plants can be tricked by this method.
