Dendrocalamus strictus CALCUTTA BAMBOO (10 seeds)

Male Bamboo, also known as Iron Bamboo or Calcutta Bamboo, and scientifically as Dendrocalamus strictus, is a perennial Asian variety from the Poaceae family. It is extremely fast-growing, capable of growing up to 30 cm per day, generally reaching 10 to 20 meters in height within a few weeks in its native habitat. This giant grass species features culms (stems) that can reach up to 10 cm in diameter, making it one of the largest bamboos in the world.

Its foliage is lush and dense, with long, narrow, lanceolate leaves measuring between 15 and 30 cm. Their color varies from bright to dark green, contrasting sharply with the golden or green stems. The leaves are leathery and slightly rough to the touch. Flowering typically occurs every 40 to 50 years. The inflorescences appear as panicles—long stalks bearing small, discreet cream or yellow flowers.

Male Bamboo seeds are elongated, 8 mm long, light gray, and closely resemble wheat grains.

- Uses:

It serves as a natural privacy screen, adding an exotic touch to gardens. The young shoots are edible and widely used in Asian cuisine. Additionally, it is used as a windbreak and for soil protection to prevent erosion.

In the construction sector, it is prized for its robustness and durability, especially for scaffolding, houses, and temporary shelters. Its resistance to compression and bending makes it an ideal ecological material.

- Germination and Sowing Seeds:

• The best time to sow Calcutta bamboo begins in May.
• Soak the seeds for 12 hours in lukewarm water.
• Bury them 2 to 4 mm deep in a mix of 80% fine potting soil and 20% sand.
• Water the substrate gently and place the culture in a spot around 25°C. Using a garden greenhouse is ideal.
• Germination usually occurs within 2 to 4 weeks after sowing.

- Soil Type / Substrate:

Indian bamboo prefers well-drained soil rich in organic matter. It thrives in slightly acidic to neutral soils but can adapt to alkaline soils. It is not a demanding plant.

- Exposure / Sunlight:

This species requires full sun to develop properly. Direct sunlight for most of the day is ideal, though it can tolerate light shade, particularly in very hot regions.

- Temperatures / Hardiness:

It is relatively hardy and can withstand temperatures down to -8°C. However, it thrives best in tropical and subtropical climates (20–30°C). Severe frosts may damage the aerial parts of the plant.

- Irrigation / Water Needs:

Iron Bamboo requires regular watering, especially during active growth and initial planting. The soil should remain moist but not waterlogged. During droughts, more frequent watering is recommended.

- Reproduction / Multiplication:

Reproduction is mainly vegetative via rhizome cuttings, which are planted in prepared soil. It can also be propagated by seeds.

- Pests / Predators:

While disease-resistant, it can be affected by sap-sucking insects like aphids and scale insects. Natural or organic treatments can help control these populations.

- Maintenance:

When planting, it is highly recommended to install root barriers (anti-rhizome barriers) to limit its spread and proliferation.
