The leaves must always be clean to avoid clogging the stomata and to promote photosynthesis. Use a damp cloth to clean them.
Avoid using leaf brighteners: most of the time they act by creating a film that ends up clogging the stomata.
Avoid exposing the plant to direct sunlight and try to place it in a cool place.
Peace lily should be placed in bright corners. An inadequate position of the plant may cause it not to flower.
Change the pot once a year. Peace lilies have many fibrous roots that harden the clod of soil in which they are planted and prevent water from penetrating. If this problem occurs, leaves and flowers will grow smaller than expected and dry out quickly.
Fertilize once a month with an eco-friendly fertilizer.
Water moderately two or three times a week. Immerse the plant in a bucket of water and wait until it stops bubbling.
If the heater is on, try spraying the leaves with water. This will ensure that it has enough moisture to flower.
Plant the peace lily in a mix of three equal parts peat moss, potting soil, and sand.
