Bamboo canes and what they are used for
Short answer: The hollow stem with nodes makes bamboo useful as a tube, pole and scaffold. The natural shape gives the strength, so the stem can be used almost as it is once it has been dried and treated.
The nodes give strength
At each node the stem is closed by a dividing wall. This stops the tube from collapsing under pressure and keeps it stiff along its length. The distance between nodes varies from species to species and affects how strong and how flexible each tube is.
Light and stiff
Because the stem is hollow, it weighs little for its length. The material sits on the outside of the tube, where it does the most good under load. It is the same principle as a metal tube. That is why a thin bamboo pole can be surprisingly stiff and still easy to carry.
Uses
Poles, scaffolding, fences, furniture and garden tools are among the most common uses. The shape largely decides what a tube is used for. Thin poles become canes and fences, while thick stems can hold up a scaffold. Some tubes are split and woven into mats, baskets and screens.
In the garden
Bamboo canes are used to support plants because they are light and stiff. They are pushed into the soil next to tomatoes, beans and flowers and hold the plant up through the season. Afterwards they can be dried and stored for next year, as long as the bottom has not started to rot.
Limitations
Untreated bamboo rots outdoors over time, especially the part in the soil. Moisture and pests are the main problems. Garden canes should be stored dry in winter and replaced when they go soft or split. For lasting structures, bamboo must be treated before it is put up.
Drying and treatment
A fresh stem holds a lot of water and must dry before it can be used. If it dries too quickly, it can crack. In many places bamboo is also treated against insects and fungus so it lasts longer. Treatment decides whether a fence or structure lasts a few years or many.
Not textiles
Textiles use the cellulose from the stem, not the tube itself. The stem is broken down, the cellulose is dissolved in a chemical process and formed into new fibres, which are spun and knitted or woven. The hard shape disappears completely along the way. Read more in what is bamboo viscose.
Why the difference matters
Many people link the word bamboo with a hard stem and are surprised by how soft a textile from the same plant can be. The difference lies entirely in the processing. The tube keeps the structure of the plant, while the fabric is built on fibres formed anew. Read why bamboo viscose feels so soft.
A grass
Although the stem is as hard as wood, bamboo is a grass. It has its thickness from the start and does not get wider over the years, which is also why it is hollow. The shape is not something people created, but something the plant provides by itself. Read more in is bamboo a grass or a tree.

If you want to feel the soft side of bamboo, towels are a good place to start. Here the raw material becomes a fabric that feels soft against the skin and is used every day. Look at size and fabric weight in the descriptions. See bamboo towels.
Frequently asked questions
Why are bamboo tubes strong?
Because they are hollow with a dividing wall at each node. The walls stop the tube from collapsing, and the material sits on the outside, where it does the most good.
Do bamboo tubes last outdoors?
Untreated bamboo rots over time, especially the part in the soil. Store canes dry in winter and replace them when they go soft or start to split.
Are bamboo tubes used for clothing?
No, not the tube itself. Textiles use the cellulose from the stem, which is dissolved and formed into new fibres that are spun into yarn and knitted or woven.
