Bamboo is an incredibly versatile and sustainable plant that has been used for a variety of purposes for centuries. As a fast-growing grass that can grow over 3 feet in just 24 hours, bamboo offers an abundant and renewable resource. This article explores the many uses and benefits of bamboo and why it has become an increasingly popular choice for everything from construction to fabric.
An Overview of Bamboo
Bamboo belongs to the subfamily Bambusoideae, which includes over 1,000 species across 75 genera. Giant bamboo is the largest species and can grow to over 130 feet tall and 7 inches in diameter. Bamboo species are found natively on every continent except Europe and Antarctica but are most abundant in East and Southeast Asia.
Bamboo is characterized by its woody, cylindrical and jointed stems. The stems emerge from an underground rhizome root system that continues to send up new canes, allowing bamboo to spread quickly and be harvested on a sustainable basis. Bamboo stems have strong fiber strands that run lengthwise, giving bamboo its tensile strength.
While technically a grass rather than a tree, bamboo has many of the same properties as wood. It is a strong, lightweight and renewable building material. Bamboo maturation cycles are much faster than traditional lumber, with new canes reaching full height in just a few months compared to decades for most softwoods. This rapid rate of growth makes bamboo an excellent sustainable crop.
The Many Uses of Bamboo
Bamboo has traditionally been used for many purposes, including construction, tools, transportation, furniture, art, clothing and food. Contemporary uses of bamboo take advantage of its sustainability as well as its unique properties. Some of the most common uses of bamboo today include:

The Growth Process and Lifecycle of Bamboo
To fully understand bamboo’s beneficial properties, it is important to comprehend the bamboo plant's growth process and lifecycle. There are two main growth forms of bamboo: running bamboo (monopodial) and clumping bamboo (sympodial).
Running bamboo varieties extend through underground rhizome networks and send up new shoots some distance from the main plant. This allows running bamboo to quickly spread across a large area, maximizing the amount of new growth each season. Common running bamboo species include Phyllostachys edulis (Moso) and Phyllostachys aurea (Fishpole).
Clumping bamboo grows in compact culms arising from a single base or root mass. Clumping bamboo expancion is limited to the gradual widening of the root system each year. Clumping bamboo is less invasive than running bamboo due to the lack of aggressive rhizome networks. Common clumping species include Bambusa multiplex (Hedge bamboo) and Bambusa textilis (Weaving bamboo).
The typical bamboo lifecycle begins with the emergence of a new shoot from the rhizome system. Culms can grow to full height in 4 to 12 weeks depending on the species. Culms continue to thicken and strengthen over the next several months before branching out with leaves. Mature culms will produce rhizome branches and roots of their own to expand the plant.
Flowering cycles vary dramatically between bamboo species, ranging from annual to decades between bloom periods. Bamboo flowers are followed by fruiting and then widespread dieback of that bamboo population, making timed harvesting especially important. After dieback, new shoots emerge from the rhizomes to restart the bamboo growth cycle.
Cultivating and Harvesting Bamboo
Bamboo can be cultivated as a specialized crop or harvested directly from wild forests. Most bamboo agriculture focuses on running bamboo varieties in regions with appropriate climate, such as warm tropical locations with ample rainfall. Several steps are involved in preparing bamboo plantations or managed bamboo groves.
Site preparation involves selecting appropriate bamboo species for the climate and soil. The land must be cleared and the soil plowed to enable new rhizomes to spread unimpeded. Bamboo rhizomes or culm cuttings are planted in furrows or holes. Irrigation systems may be installed if rainfall is insufficient.
Bamboo requires fertilization for optimal growth, especially during early establishment. Compost, manure or commercial fertilizers are worked into the soil. Regular weeding is necessary until the bamboo thickets become dense enough to block out other plants. Flowers must be promptly removed to preserve bamboo vitality.
Selective harvesting of mature culms keeps the plantation productive. Culms over 3 years old start to die off and should be cut first. No more than 1/3 of culms should be taken from any area during a single harvest. Managing dense clumps also helps maximize usable bamboo.
Wild bamboo harvesting targets stands with ample culms of the appropriate maturity. Since wild bamboo is not fertilized or irrigated, harvesting impact must be minimized through limited cutting and wise species selection. Following best practices allows bamboo to be harvested sustainably.
