The perfect house plant: How to care for your Peace Lily
Spathiphyllum (Spathiphyllum commutatum) is a classic indoor plant grown for its lush green strappy leaves and long-lasting white flowers. The flowers are spathes and consist of a large white ‘petal’ that wraps like a hood around a central spike or spadex. The flowers are held on stiff stems above the green leaves and last for weeks. They can occur throughout the year.
It's best known as a peace lily or Madonna lily and grows happily in homes or offices in a brightly-lit spot. In warm, frost-free gardens it can also be planted in a shaded garden or grown in a courtyard.
Care and troubleshooting
Care couldn’t be easier. Place plants in a brightly-lit spot, which is sheltered from draughts. Water when the potting mix is dry to the touch and don’t allow pots to sit in water. Plants that have become overly dry will wilt. These pots may need to be soaked in water to rehydrate the potting mix and allow the plant to revive.
Dust the leaves from time to time and repot when the plant becomes too large for its container. Use a good quality potting mix, such as Supersoil Professional Indoor, Balcony and Hanging Basket Mix, and feed with an indoor-specific liquid fertiliser such as Osmocote Pour+Feed House Plant Fertiliser occasionally when the plant has new growth. Remove dead blooms and leaves, cutting them at the base.
Black leaf edges or black leaves and stems indicate overwatering and wet soil conditions. Check that drainage holes in the base of the pot are not blocked and cut back on watering. Cut off discoloured leaves, removing them at the base.
Brown leaf edges or spots may result from overwatering or exposure to draughts, air conditioning or heating. Remove discoloured leaves and relocate the plant to a more sheltered position.
Frequent wilting may indicate that plant has outgrown its potting mix and needs to be repotted into a slightly larger pot with fresh potting mix.
Fungal gnats may breed in overly wet potting mix. These pests are seen as small ‘flies’ hovering around plants. Avoid overwatering and allow wet mix to dry out completely. Repotting in good quality potting mix may help reduce pest numbers.
