CARE GUIDE

How to keep Polyalthia Suberosa.

Light

Polyalthia comes from open habitats, like sunny meadows and forest margins, which provide plentiful light. It thrives in Full Sun but can also tolerate Partial Sun, adapting well to different sunlight conditions.

Water

Polyalthia thrives in tropical rainforests, where it benefits from high humidity and consistent moisture. Although it is drought-tolerant, it only needs to be watered every 2 to 3 weeks. As an evergreen plant, Polyalthia stores water in its leaves, making it well-suited for indoor settings with controlled humidity.

Temperature

Polyalthia comes from tropical areas, where the climate is generally warm and humid. Consequently, it is adapted to high temperatures and humidity. It does not tolerate sudden temperature changes and prefers a consistent temperature environment, so it is important to prevent temperature fluctuations indoors. It typically cannot stand cold and needs warmer conditions to grow. If the ambient temperature falls too low, the plant may stop growing or even die.

Fertilizer

Fertilization is essential for Polyalthia care. Regular feeding throughout the growing season maintains the energy needed for its showy foliage and promotes overall growth. Lack of fertilization can lead to unhealthy leaves, reduced ornamental value, and stunted or weak growth that is more prone to breaking.

Pruning

Polyalthia is an evergreen shrub or small tree known for its glossy leaves and fragrant flowers. To maintain its health and beauty, it's best to prune in the early to late winter months. During pruning, remove any dead wood and overcrowded branches to improve air circulation and maintain an attractive shape. Always use sterile tools to encourage healthy growth and enhance its ornamental appeal.
