Bamboo and Water Use – Why the Plant Needs So Little

Short answer: On most plantations bamboo gets by on rainwater alone and therefore needs far less irrigation than conventional cotton, for example. The plant's deep root system also holds moisture in the soil and prevents erosion.

Why does bamboo need so little water?

Bamboo typically grows in regions with natural rainfall, and its permanent root system makes the plant good at taking up and holding water in the soil. Because the root system stays in place after harvest, there is no need to plough and water from scratch – new shoots come up on their own.

Bamboo vs. cotton on the water accounts

Conventional cotton is one of the thirstiest crops in agriculture and is often grown with intensive irrigation. Bamboo's low water use is therefore one of the material's strongest cards – but remember that processing it into viscose uses water and chemistry too. You will find the nuanced walkthrough in the honest guide to bamboo and the environment.

What does that mean for your clothes?

If you choose bamboo viscose instead of conventional cotton, you are choosing a raw material with a far lower need for irrigation in the field. See the material in action in bamboo underwear for men, bamboo underwear for women and bamboo bedding – and read about looking after it in the washing guide.

Frequently asked questions

Does bamboo need to be irrigated?

As a rule, no. Most bamboo plantations manage on natural rainfall, because the plant grows in rainy areas and has a deep root system.

Does bamboo use less water than cotton?

Yes, in the growing stage. Conventional cotton often requires intensive irrigation, while bamboo typically grows on rainwater alone.

Is water used in the production of bamboo viscose?

Yes. Processing the plant into fibre uses water and chemicals, so the overall accounts also depend on the factory's process.
