The Khaya senegalensis, or the African Mahogany tree, is an extraordinary species with a wide range of uses and benefits. Commonly known as the Xà Cừ tree in Vietnam, it has a long and fascinating history, with a native origin in Sudan, Africa, and a widespread presence across the globe, particularly in Berlin, Germany. This tree is a true testament to nature’s wonders.
1 What is the Xà Cừ Tree?
Origin and Significance of the Xà Cừ Tree
The Xà Cừ tree, also known as the Nacre Tree in English
The Xà Cừ tree, scientifically known as Khaya senegalensis, belongs to the Meliaceae family. This majestic tree, also referred to as the “sọ khỉ” in Vietnamese, boasts a global presence, with the largest population found in Berlin, Germany. Its English name, Nacre Tree, hints at the tree’s unique characteristics and beauty.
The Xà Cừ tree is widely planted throughout Vietnam, from North to South
In Vietnam, the Xà Cừ tree has become a popular choice for landscaping and ornamental purposes. Its adaptability to various soil types, especially the sandy soils of the central coastal regions, has made it a common sight across the country. Majestic rows of century-old Xà Cừ trees line the streets, grace school campuses and public parks, and provide a serene backdrop to village temples and national parks.
Feng Shui Significance of the Xà Cừ Tree
While some believe that large trees with thick trunks should be avoided near the main entrance of a home to prevent blocking positive energy and sunlight, the Xà Cừ tree can be an exception. By maintaining a certain distance and planting it to the left when viewed from the inside out, approximately 20 meters from the main gate and the house foundation, it can provide a soothing shade from the summer heat without disrupting the flow of energy.
The Xà Cừ tree holds a special significance in Feng Shui practices
Additionally, Xà Cừ wood is highly valued in Feng Shui practices. Its reddish-brown hue is used to craft exquisite objects, such as the “disk of the four divine creatures” (Long, Ly, Quy, and Phụng), meticulously carved from a single piece of Xà Cừ wood. It is also commonly used to build ancestral altars, adorned with intricate carvings, to bring blessings and harmony to the family.
Characteristics of the Xà Cừ Tree
The Xà Cừ tree is a tall, straight-growing tree, reaching heights of 20 to 50 meters with a trunk diameter of 1 to 2 meters. Its bark is grayish-black and rough, and the tree boasts a lush, wide-spreading canopy. The leaves are feather-like, growing in an alternating pattern, with a smooth upper surface. The flowers are white and clustered, and the fruits are grayish-brown capsules that split open when ripe, revealing valuable brown seeds.

The Xà Cừ tree is prized for its ability to withstand strong winds and its deep, sturdy roots that help prevent soil erosion. Its wide-spreading canopy and air-purifying qualities make it an excellent choice for creating green spaces and enhancing the beauty of landscapes.
However, when planting Xà Cừ trees along roadsides or in parks, it is important to maintain a diameter of less than 400mm and to prune the branches before the rainy season to prevent accidents caused by falling branches or toppling trees.

3 How to Grow and Care for the Xà Cừ Tree
Growing Xà Cừ Trees at Home
When choosing seeds for planting, select healthy, disease-free seeds from trees that are at least 18 years old to ensure the best quality. The rainy season is the ideal time to plant Xà Cừ trees.
Choose healthy, disease-free seeds from mature Xà Cừ trees
For large-scale planting, maintain a spacing of 4 to 5 meters between trees and 3 to 3.5 meters between rows, with an ideal density of 626 trees per hectare. Dig holes approximately 50x50x50cm in size, and prepare the soil by mixing in a small amount of NPK fertilizer about ten days before planting.
Soak the seeds in warm water for about an hour, then wrap them in a thin cloth and place them in a well-ventilated area to germinate. Keep the seeds slightly moist, and once they have sprouted, they are ready for planting.
Transplant Xà Cừ seedlings when they reach a height of 40-50 cm into the prepared planting site
After about a week, transfer the seedlings to pots containing a mixture of organic matter, manure, soil, and phosphate fertilizer. Remember to puncture holes in the bottom of the pots for drainage. Once the seedlings reach a height of 40-50 cm, they are ready to be transplanted to their permanent location. Remove the pot, trim any excess roots, and place the seedling in the prepared hole. Fill the hole with soil, tamping it down gently to secure the roots, and water the plant, being careful not to overwater, as this can cause root rot.
Caring for Xà Cừ Trees
Water Xà Cừ trees twice a day when they are young, and reduce watering to once a day as they mature
- Watering: When the tree is young, water it twice a day. As it matures, reduce watering to once a day.
- Weed Control and Soil Management: Keep the area around the tree free of weeds and trim the soil to a diameter of 0.8-1 meter. Prune the branches to maintain a height of ⅓ to ½ of the total tree height to promote healthy growth.
- Pest Control: Regularly remove weeds, especially when the tree is young, to prevent pest infestations. If pests are detected, use specialized pesticides to prevent the spread of the infestation.
Notes on Growing and Caring for Xà Cừ Trees
- When purchasing Xà Cừ tree seedlings, choose ones with straight trunks and undamaged leaves. Avoid seedlings with any unusual signs.
- The ideal soil pH for growing Xà Cừ trees is around 6 to ensure optimal growth.
