About Tree of heaven
Ailanthus altissima, commonly known as the tree-of-heaven, is a fast-growing deciduous tree native to China. Its pinnately compound leaves and columnar shape make it striking, though it is valued more for its hardiness and adaptability than for its ornamental garden appeal. Due to its invasive nature, caution is advised when considering its planting outside its native habitat.
Native range
China and northern Vietnam
Care tips
This species is extremely adaptable and tolerates a wide range of conditions, from full sun to partial shade and poor or disturbed soils. Watering is only necessary during extreme droughts, as it is very drought-tolerant. It requires no fertilization, and any substrate, even low-quality ones, is suitable given its pioneering nature. The most common mistake is planting it without considering its invasive potential, which can lead to ecological and structural problems.
