So many are curious about bamboo and its benefits to our environment. So as part 2 of our knowledge base about this incredible plant, we answer some of the most common questions many still have. 

 

If you’ve read Everything You Need to Know about Bamboo and other blog articles, you probably already know that there are over 1,000 species of bamboo in the world and thousands of applications and uses. It is the most versatile plant in the world and definitely worth learning about. 

 

How Does Bamboo Spread ?

There are two types of bamboo roots – clumping and running bamboo. Clumping bamboos have a pachymorph rhizome system whose buds underground grow upwards instead of outwards making it more controllable as it spouts directly up from the ground. Running bamboo has a leptomorph rhizome system which grows laterally underground pushing through the soil with new rhizomes growing perpendicularly to its parent rhizome.. The running bamboo can spread as far as 20 feet underground from its original parent rhizome and can spread as much as 3 to 5 feet per year.

Why Does Bamboo Grow So Fast? 

Certain species of bamboo, like the moso bamboo, can grow as fast as 0.00003 km/ hr or 1.5 inches per hour. Several studies have found that plant hormones including gibberellin, indole acetic acid and zeatin may play a role in promoting the fast growth rate of bamboo shoots.

Gibberellin (GA) is one of the plant hormones that regulate a wide range of processes involved in plant growth. Indole-3-acetic acid (IAA) is an auxin produced by terrestrial plants, like bamboo, which influences development through a variety of cellular mechanisms, such as cell elongation. Zeatin promotes growth of lateral buds.

How Does Bamboo Grow?

Bamboo grows in marginal land with little to no pesticides required. Bamboo stores sugars in its underground rhizomes (root system) and as it grows, it produces fine root hairs and buds that develop into new rhizomes. Each culm breaks through the soil surface as its final mature diameter (its stalk’s diameter does not widen as it grows). The culms (stem) grow to its full height between 30 – 60 days and its branches and leaves fold out from the culm in the next 30 – 60 days.

Because bamboo has high tolerance to various environments, bamboo is a good candidate for afforestation, carbon sequestration and climate change mitigation. 

 

Is Bamboo a Grass?

Yes, bamboo (subfamily Bambusoideae) is a grass. It is a subfamily of treelike grasses called Poaceae. Bamboo has more than 115 genera and approximately 1400 species.

How Tall Does Bamboo Grow?

Some species of bamboo can grow as high as 30 meters or 100 feet high and 10 – 12 inches in diameter.

 

How Long Does It Take Bamboo to Grow?

Bamboo takes about three years to get established. Once established the new shoots that emerge in the Spring (they will still only grow for 60 days) will continue to get bigger and more numerous from year to year as the colony grows towards maturity.

 

What Do the Rings on the Bamboo Mean?

The bamboo rings are called nodes. Each culm (stem) is segmented by these nodes or joints.

Cam Bamboo Act as a Fire Retardant?

Because it contains large amounts of silicate acid, bamboo is abnormally flame resistant and could curb forest fires. Making clumping bamboo a part of a tropical reforestation effort could be beneficial to reducing future instances of wildfires.

 

Can Bamboo Prevent Soil Erosion?

Because bamboo is a grass, it has a very shallow root system. Most of its rhizomes live on the top 6 inches of the soil while the rest can spread as deep as 14 inches. Because the roots are so densely clumped, they help to deter soil erosion which reduces soil fertility and contributes to flooding and landslides.

How Does Bamboo Help with Climate Change?

Bamboos helps to mitigate the effects of climate change by: 

  • Absorbing and storing carbon during its fast growth and frequent harvesting process which happens more often than trees, bamboo can store and absorb more carbon 
  • Protecting forests by mitigating the spread of wildfires with its unique fire retardant characteristics
  • Protecting watersheds by reducing soil erosion that produces sediments that block waterways making areas more susceptible to flooding
  • Insulating environments against extreme weather because of its flexibility and resilience in surviving natural disasters including typhoons and hurricanes
  • Providing low-cost, green housing option that produces lower carbon emissions
  • Providing cleaner biofuels that reduce our reliance on fossil fuel extraction and production

 

Does Bamboo Produce More or Less Carbon than Trees?

When plants decompose, they release carbon dioxide. When bamboo is actively managed (harvested), farmers will harvest the mature bamboo culms before they decay, so the total amount of carbon stored by the ecosystem increases as new culms emerge faster than they decay resulting in more carbon sequestered in subsequent years. Harvesting bamboo culms doesn’t kill the plant and the extensive rhizome (root system) continues to store the carbon below ground even after the bamboo is harvested.

 

As long as bamboo forests or farms are actively harvested and remain productive, more carbon is sequestered than produced from decaying culms.

 

On the other hand, when trees are clear cut, there is a huge loss of carbon arising from the decomposing organic matter and because it would take 13 years before the replanted tree begins to absorb more carbon than its releasing from the decomposition, the net effect is a net loss of carbon when trees are harvested.

 

Why Does Bamboo Release More Oxygen than Trees?

Because of bamboo’s fast growth and replenishment rate (it is the fastest growing plant in the world), it experiences photosynthesis more often than other types of plants. Photosynthesis is the process that transforms light energy into oxygen and glucose.

 

Within the plant cell, the water (H2O) is oxidized (losing electrons) and transforms into oxygen  while the carbon dioxide (CO2) is reduced (gains electrons) and transforms into glucose or sugar that the plant stores for its future use for growth.

 

Some bamboo species, like Thamnocalamus and Sasa Fargesia, need little sunlight but still perform the same photosynthesis process. Because of bamboo’s fast growth rate and its ability to thrive even in partial sunlight or shade, a grove of bamboo can produce 35% more oxygen than trees of the same area.
