The Xà Nu tree is a unique and significant species, famously featured in Vietnamese literature. Let’s explore the beauty and importance of this special tree.

1 What is the Xà Nu Tree?

Origin and Significance of the Xà Nu Tree

The Xà Nu tree is a fictional creation of author Nguyen Trung Thanh in his renowned work, “Rừng Xà Nu” (Xà Nu Forest). Drawing inspiration from the three-needled pine tree, locally known as “loong rúh” by the Tay Nguyen people, Nguyen Trung Thanh crafted the artistic concept of the Xà Nu tree. In nature, pine trees are classified into two types: the two-needled variety, valued for its resin, and the three-needled variety, utilized for timber.

In “Rừng Xà Nu,” Nguyen Trung Thanh vividly portrays the Xà Nu tree as resilient and robust. The Xà Nu tree stands as a symbol of resistance, protecting the villagers of Xô Man from the enemy’s cannons. It is also integral to their daily lives, providing materials for various household items such as boards, Xà Nu resin, and Xà Nu oil.

The Xà Nu tree represents the serene beauty of nature, artistically elevated by the author to symbolize the extraordinary resilience of the Tay Nguyen people.

Origin and Significance of the Xà Nu Tree

Characteristics and Classification of the Xà Nu Tree

The three-needled pine thrives in a cool climate with ample mist and nutrient-rich soil, typically found at altitudes above 900 meters. It is prevalent in Southeast Asia, India, China, and in Vietnam, it is mainly found in highland regions such as Langbiang, Lâm Viên, and Di Linh plateaus.

Characterized by its straight, round trunk and grayish-brown bark, the Xà Nu tree typically grows to a height of 30-40 meters. Its resin is scarce and has a strong odor. The needles are green, stiff, and approximately 20-25 centimeters long, with three needles per branch tip.

The cones of the Xà Nu tree are egg-shaped and unisexual, with female cones typically taking two years to mature and becoming woody upon ripening. Each cone measures 5-9 centimeters in height and 4-5 centimeters in width, with a curved stalk about 1.5 centimeters long.

2 Benefits of the Xà Nu Tree

The three-needled pine contributes to the ecological diversity of the highland forests. Due to its low resin content, it is primarily valued for its lightweight timber. Historically, its wood was used for ammunition casings, and its resin served as lamp fuel. Additionally, the resin can be processed to produce colophonium (also known as rosin) and pine oil, which is used to polish hats.

3 Planting and Caring for the Xà Nu Tree

Seeds:

  • After collecting the seeds, it is best to soak them in a 0.1% potassium permanganate solution for 15 minutes and then rinse them. Next, soak the seeds in warm water at approximately 45 degrees Celsius for 24 hours, discarding any seeds that float. Dry the seeds in the sun and then store them in a cloth bag in a cool, ventilated area. Rinse the seeds daily with warm water and dry them before continuing to soak.
  • In cold climates, you can use a lamp to aid germination. Once the seeds have sprouted, plant them in pots or beds. For long-term storage, place the seeds in glass jars or wooden boxes and keep them in a dry place; they can be stored for up to two years.

Sowing Seeds in Pots:

  • Before sowing, moisten the potting mix, and poke a hole about 0.6 to 0.8 centimeters deep. Place one or two seeds in the hole and cover it. Water the seeds with a fine spray, and then cover them with sterilized straw or pine needles.

Sowing Seeds in Beds:

  • Prepare a well-aerated, sieved soil mix with a 1-centimeter sieve size. Cover the surface of the bed with a layer of fine sand, approximately 5-8 centimeters thick. The bed should be 1 meter wide, 5-10 meters long, and 10-15 centimeters high, with a 50-60 centimeter wide trench. When the seeds have sprouted, spread them evenly over the bed and water them as you would when sowing seeds in pots.

Transplanting Seedlings:

  • Before transplanting, thoroughly water the potting mix and use a bamboo stick to poke a hole deeper than the seedling’s roots. Place the seedling in the hole so that the root collar is about 3 millimeters below the surface of the mix. Use the stick to firmly pack the soil around the roots, and water regularly to keep the seedling moist.

Watering:

  • Water the trees twice a day, once in the morning and once in the afternoon. For the first two months, water twice a day, then reduce to once a day for the third month onwards. From the fifth month until the tree is mature, water twice a day. Avoid overwatering, as it can cause root rot.

Pests and Diseases:

  • To prevent pest and disease problems, you can spray the trees with Basudin to control ants and crickets. Additionally, spray with Benlate 0.2-0.5% at a rate of 0.3 liters per square meter every two weeks to prevent root rot. For leaf blight control, spray with Bordeaux mixture 0.5-1% at a rate of 1 liter per 4-6 square meters every two weeks.

  • Regularly check for damage caused by animals such as mice and birds, and set traps to protect the trees.
  • If you notice signs of yellowing or stunted growth, aerate the potting mix and improve drainage. Additionally, supplement the soil with a small amount of compost, spreading it evenly over the surface of the potting mix and keeping it moist.
