Combretum quadrangulare SAKAE NAA (5 seeds)

Sakae Naa, or Combretum quadrangulare in Latin, is an Asian tree native to Vietnam, Cambodia, Laos, and Thailand. It belongs to the Combretaceae family. In tropical climates, it can reach up to 10 meters in height. It is a fast-growing tree with evergreen foliage.

Leaves are opposite and oval-shaped, with smooth or sometimes slightly wavy edges. Their texture is leathery; they are dark green on the top and lighter underneath. The flowers are small and grouped in panicle inflorescences, ranging in color from white to cream, sometimes with hints of pink or red.

Fruits are small drupes, often ovoid or slightly flattened. As they ripen, they turn brown or black and contain a single seed.

Combretum seeds are light brown and have a very unique shape, consisting of 4 wings, and usually measure about 2 centimeters.

- Properties / Uses:

This plant is of significant interest due to its traditional uses and medicinal potential. It is frequently studied for its pharmacological properties and applications in traditional Asian medicine.

In China, Sakae Naa is used to treat colds, sore throats, and to relieve pain. Independent studies have confirmed its anti-inflammatory and antibacterial properties.

In Thailand and Myanmar, it is consumed as a medicinal herb; farmers often harvest the leaves themselves to chew or smoke them. The effects are energizing or mildly sedative, depending on the dosage. It can be prepared as decoctions, extracts, or infusions to treat inflammatory diseases and digestive disorders.

- Germination and Sowing:

• The most favorable period to sow Sakae Naa is from late May to late July, as it requires warm temperatures day and night to guarantee optimal germination.
• Soak the seeds for 6 to 12 hours in lukewarm water to break dormancy.
• Use a tray or a large pot with acidic-pH horticultural potting soil.
• Plant the seeds "tail-up" at a depth of 2 cm.
• Firm the soil and water gently.
• Place the plantation in a greenhouse at a temperature of 35°C to 40°C.
• Germination typically begins after 2 to 3 weeks.

- Type of Earth / Substrate:

The substrate should be well-drained and rich in organic matter. This tree thrives best in light, sandy, or loamy soil with excellent drainage to avoid excess moisture.

- Exposure / Sunlight:

It requires full sun for optimal growth. High light exposure promotes flowering and foliage development. While it can tolerate partial shade, its growth will be less vigorous.

- Temperatures / Hardiness:

It prefers warm, subtropical temperatures between 20°C and 35°C. It must be protected from frost, as it is sensitive to temperatures below 10°C.

- Irrigation / Watering:

Watering should be regular during the growth period, keeping the soil slightly moist. In winter, reduce the frequency of water supply.

- Multiplication / Reproduction:

Propagation of Sakae Naa is primarily done by seed or by cuttings. Cuttings take best using semi-hardwood shoots in summer under high humidity conditions.

- Pests / Diseases:

Combretum quadrangulare can be attacked by aphids, scale insects, or spider mites.
