Bamboo rhizome

Bamboo rhizomes (Bambusoideae sub-family) are underground stems that play a crucial role in how bamboo grows and spreads. Unlike roots, which mainly absorb water and nutrients, rhizomes store energy and produce new shoots and roots, allowing bamboo to propagate.

There are two main types of bamboo rhizomes:

1. Running Rhizomes (Leptomorph)

• Growth Pattern: Horizontal and spreading, often aggressively.

• Spread: Can travel long distances underground, sending up shoots far from the parent plant.

• Species Examples: Phyllostachys, Pleioblastus.

• Impact: These bamboos can become invasive without containment measures.

2. Clumping Rhizomes (Pachymorph)

• Growth Pattern: Short, thick, and upward-growing.

• Spread: Stay close to the original plant, forming tight clumps.

• Species Examples: Bambusa, Fargesia.

• Impact: Less invasive and easier to manage.

Key Functions of Bamboo Rhizomes

• Propagation: New bamboo culms (stems) grow from rhizome buds.

• Storage: Store nutrients and water to support growth, especially during dormancy.

• Survival: Help bamboo recover after damage by producing new shoots.
