Knowledge from Olle Garden Bed: How Fast Does Bamboo Grow?

Bamboo is a charming plant that is very different from other plants we are accustomed to seeing. One thing that everyone seems to know about bamboo is that it is a very fast growing person, but how fast does bamboo grow? There may be more answers than you expected! Read here are some things that you should know when It comes to Olle Garden Beds!

Does bamboo grow fast? What is its growth rate?

Bamboo is the fastest growing plant on Earth, growing about 35 inches (89 centimeters) per day, and faster species can grow up to 1.5 inches (β‰ˆ 4 centimeters) per hour. In its initial growth stage, this will be an increase of approximately 0.025 inches (0.6 millimeters) per minute. Of course, this is also under ideal growth conditions.

Indoor bamboo plants without simulating native conditions may never have enough space to fully utilize their potential, and if grown indoors as container plants, their upward trajectory may be very limited.

How fast does bamboo grow?

Under ideal conditions, the growth rate of bamboo may be shocking. Here are some methods to better grasp the growth rate of bamboo, divided into easy to master increments:

Every hour

Some bamboo grows up to 1.5 inches (β‰ˆ 4 centimeters) per hour, including one of the fastest growing bamboo species, tropical giant bamboo or dendrobium. At this speed, approximately one paper clip is added to the height of the bamboo every hour.

Within a day

Bamboo of different species can grow to an average of 35 to 40 inches (90 to 100 centimeters) per day. Once a plant reaches its mature size, this daily growth rate slows down. This is approximately equivalent to the height of 10 stacked popsicles.

Within a week

Within a week, the growth rate of bamboo is 35-40 inches (90-100 centimeters) per day, and some faster growing bamboo species can reach 20 feet (6 meters) within a week. This is the average size of the factory height that the pickup truck has increased in just one week!

Within one year

At a speed of 20 feet (6 meters) per week, for 52 weeks a year, if a bamboo tree continues to grow at the same speed throughout the year, it will be able to grow to over 1000 feet (305 meters). This does not happen in reality, on the contrary, bamboo reaches maturity size at approximately 3 or 4 months of age, with a maximum height of 100 to 150 feet (30 to 45 meters). This may be because it is too difficult to absorb nutrients and water from the soil into the aboveground parts of plants, so bamboo must self edit and maintain a "reasonable" height in order to survive.

Why does bamboo grow so fast?

You may want to know why bamboo grows so fast, and why it grows so fast. When faced with the extreme speed of bamboo growth, these are all reasonable questions.

The reason why bamboo trees grow so fast is because they begin to grow on the forest floor, obscured by all other older and taller growth. In order to have the opportunity to compete with other plants in the forest, bamboo must quickly reach the light! Bamboo is more concerned with increasing its height and then increasing its circumference, as it only needs to prioritize getting sunlight above all else.

Once bamboo reaches a height where it no longer competes with other plants, it will focus on maturing a bit in size and diameter until it is fully established in the environment. At this stage, developing thicker stems is important to avoid the possibility of stem breakage under adverse conditions.

As for how bamboo grows so fast: at least at the molecular level, this is still relatively unknown. Scientists have not yet figured out how bamboo cells can reproduce and form cell walls so quickly to rapidly increase growth.

How long does it take to grow full-size bamboo?

Due to its fast growth rate, most types of bamboo can reach maturity size between two to four months old, although bamboo plants may take several years to fully develop and establish in a region. The spread of a region also depends on your bamboo type: running or clumping.

Clusters of bamboo take longer to unfold and typically only spread a few inches per year. This makes clustered bamboo varieties easier to control, but it takes longer to fill an area. Running bamboo can spread from its original planting site to 20 feet, and can spread up to 5 feet per year. This is a great type of bamboo that can quickly occupy an area and make it aggressive in most places.

Ideal growth conditions

As is well known, bamboo is a fast-growing plant, but unless it has suitable growth conditions, it will not grow to its maximum capacity. The following is a list of the best ways to mimic the natural habitat of bamboo to achieve optimal bamboo growth:


The soil should be well drained and fertile. Avoid dense soil that is prone to flooding; These types of soil need to be modified for better drainage in order to cultivate most bamboo varieties. Along a similar vein, dry, nutrient poor soil also needs to be modified to include more humus.


Bamboo is best grown in sunny areas, but some shelters should be provided to protect it from bright afternoon light. Some lighting conditions are also suitable for most bamboo varieties; Essentially, as long as there is little bright direct light, the growth of bamboo will not be hindered.


Regularly water after transplanting; Avoid drying the soil, especially during summer planting. Bamboo usually cannot tolerate damp soil, so please ensure that you plant it in a well ventilated and well drained area. Once a plant is established, it is quite drought resistant, so if you are in an area where it often rains, you may not need to do any additional watering.

Apply fertilizer

Fertilization was applied monthly during the first growing season of bamboo, and started one month after planting. After the establishment of bamboo, there is no need to fertilize it.

Growth control

Avoid making your plants grow weeds and invasive, as most bamboo species can do so. Species formed by clumps are easier to control, spreading only a few inches per year. Running species are usually invasive species, so they should be planted in flower pots or vertical barriers should be used to prevent bamboo from invading nearby native habitats.


Splitting and removing withered vines can help keep bamboo clean and prevent pests and diseases that can thrive in dying or decaying tissues. Sharp scissors and even hand saws (disinfected before use) are most suitable for trimming dead stems. Ensure trimming and clean cutting on the soil line. This will make fungal or bacterial infections less likely to attack your bamboo.

Common problem

Is bamboo the fastest growing plant?

Among the hundreds of bamboo species that exist on Earth, they are considered to be the fastest growing plants we know so far. This is partly due to its growth habit of growing straight and maintaining slender stems until reaching maturity height.

What is the fastest growing bamboo?

Make (Phyllostachysreticualta) and Moso (Phyllostachysedulis) are the fastest growing bamboo varieties, capable of growing over one inch per hour, with a maximum height of 150 feet (45 meters), and a diameter of 14 inches (35 centimeters) per stem.

How big is bamboo?

One of the largest bamboo species, giant bamboo or Guaduagiganteus, can grow up to 115 feet (35 meters) tall, although other varieties have already reached 150 feet (45 meters) tall. It seems that there are not many species higher than this, as plants too high may be detrimental.
