Neolamarckia cadamba: complete guide

Overview

Neolamarckia cadamba, commonly called Kadam or Leichhardt-pine, is an impressive tropical tree from the Rubiaceae family. This tree is prized for its full, rounded crown and striking, spherical flower clusters. In Asia, it has been cherished for thousands of years.

Appearance & bloom

The Kadam tree grows to a substantial height and develops dense, dark green foliage. The most distinctive feature is the flowers: they grow in spherical, yellow to cream-colored clusters. These ball-shaped inflorescences bloom over an extended period.

Ideal location

This tree absolutely prefers a sunny spot with at least 6-8 hours of direct sunlight daily. The plant should be well-protected from cold winds. In temperate climates, a warm, sheltered position works best.

Soil

Provide well-draining, fertile soil with adequate organic matter. A pH between 6.0 and 7.0 is ideal. When growing in containers, use quality potting mix with good drainage.

Watering

Regular watering is essential, especially during the growing season. Keep the soil consistently moist but not waterlogged. Reduce watering in winter. The tree may shed leaves if conditions become too dry.

Pruning

Pruning is not always necessary, but you can shape the tree or remove dead branches. The best time to prune is at the end of the dormant season, before new growth starts.

Maintenance calendar

Spring: Begin feeding and increase watering as growth starts. Summer: Maintain consistent moisture, feed monthly. Fall: Gradually reduce watering and feeding. Winter: Minimal watering, no feeding needed.

Winter hardiness

This is a tropical tree and cannot tolerate frost. In climates with temperatures below 10C, you must protect the tree or bring it indoors. Many gardeners move potted specimens indoors for winter.

Companion plants

The Kadam tree grows well with other tropical plants. Try shade-loving plants at its base. Ensure companion plantings do not compete for water and nutrients.
