Gardening and plant expert Lucie Bradley from Easy Garden Irrigation has provided valuable insights into the optimal conditions for a peace lily to flower. According to Bradley, while the first window for blooming has passed in spring, peace lilies still have the potential to flower in late summer or early autumn.
Peace lilies are known for their long-lasting blooms, which can last up to eight weeks, offering a beautiful and elegant display. However, achieving these blooms requires careful attention to the plant’s light requirements. “The usual culprit when it comes to your peace lily not flowering is a problem with how much light it is receiving,” Bradley told Express.co.uk. “Too much direct sunlight or too little light will both prevent your plant from producing blooms.”
Bradley recommends placing peace lilies in bright, indirect sunlight, ideally near a north or east-facing window. “These locations provide the perfect balance of light to encourage flowering without causing damage to the plant,” she explained.
On the other hand, too much direct sunlight can scorch the leaves, leading to yellowing and brown tips. Conversely, insufficient light can cause the plant to stretch out, producing longer stems and horizontal leaves as it seeks more light.
Bradley also noted that some peace lilies may not flower simply because they are too young. “Just because a peace lily was in flower when you bought it doesn’t mean it was old enough to be flowering naturally,” she said. Plants in pots smaller than 15cm across are often too immature to bloom naturally and may have been forced into flowering through controlled conditions and the use of gibberellic acid, a plant hormone.
“After this type of treatment, your plant may flower for a couple of months and then stop until it’s old enough to naturally flower,” Bradley added. She emphasized that peace lilies typically reach maturity and begin to produce their signature white flowers consistently when they are two to three years old, provided they receive the correct care and attention.
