Anthurium plants are well-loved for their vibrant, heart-shaped flowers and lush foliage, making them a popular choice for many indoor gardeners. However, it’s not uncommon for anthurium owners to encounter the issue of curling leaves, which can be a cause for concern. Several factors can contribute to this problem, and pinpointing the cause is essential in order to provide the best care for your plant.
