How to grow bamboo
All you need to know about growing bamboo, with advice on growing clumping and running types.
Bamboos are popular garden plants, grown for their fast growth and architectural stems (culms). Some bamboos are perfect for using in tropical planting schemes, while others are more suited to contemporary or urban designs. Some clump-forming species work well as natural screening. There’s a huge range of bamboo plants to choose from, ranging in colour from black to yellow.
Some bamboos grow into large clumps, making them suitable for using as screening, adding structure or using as a focal point.
However, other species can quickly outgrow their allotted space and they can look unattractive if not managed properly. If left to grow out of control they can be virtually impossible to remove.
How to grow bamboo
There are two types of bamboo: clumping and running. Clumping bamboo plants grow in clumps. Running bamboos bear long underground stems, or rhizomes, from which new growth appears, enabling them to colonise new ground.
Most bamboos thrive in moist, well-drained soil. They can be grown in most soil types, but some do better in acid soil – avoid wet, boggy or dry conditions. Most bamboos prefer sun but some species, such as Sasa bamboos, can be grown in shade. Plant your bamboo in spring to encourage it to develop good roots and canes before becoming dormant in autumn. Feed with a balanced fertiliser throughout the growing season and allow some bamboo leaves to accumulate around the base of the plants, as they return nutrients, particularly silica, to the roots, helping the plants stay strong and healthy.

Where to grow bamboo
Bamboos can be grown in almost any situation. Plant bamboo at the back of the border to create height, in your lawn to make a focal point, against a fence or wall to create a screen, or as a contemporary hedge. You can also grow bamboo plants in a pot – some compact varieties do well in large pots, while other 'running bamboos' are best grown in a container to prevent them from growing out of control.
How to plant bamboo
Running bamboos can be invasive, so it's best to control their growth by growing them in containers or digging a trench and lining it with paving slabs or other impermeable material, so the bamboo can't 'run'.
To plant clumping bamboo in the ground, dig a hole twice the size of the rootball. Plant the bamboo so its rootball sits level with the ground surface. Backfill with soil and water in well.
How to care for bamboo
Bamboo plants are hungry and do best when given a regular liquid feed from spring to autumn. Remove dead leaves from around the base of plants, although allow some to remain as they return the nutrient silica to the plant's roots.

It's important to carry out regular root inspections, particularly if you're growing running bamboo. Dig down around the base of the plant and remove stray root growth with a sharp spade, to keep growth in check.
In this video guide, Tim Penrose of Bowden Hostas reveals his three golden rules for growing bamboos, including the varieties to grow if you're worried about them spreading, what to do with fallen leaves and tips on splitting them:
How to propagate bamboo
Divide bamboo clumps in spring, using a sharp spade to separate bits of root from the main rootball. Replant in the ground and water well.
Growing bamboo: problem solving
Bamboos rarely suffer from pests and disease. The main problem associated with growing bamboo is when running bamboos grow out of control. Find out how to control the spread of running bamboo, in our video, above.
How to contain running bamboos
If your heart's set on growing a running bamboo then don't panic, there are ways to contain its growth and stop it growing out of hand. The key is to prepare well in the first place and be vigilant.
- Dig a trench 40-60cm deep, and line it with overlapping impermeable materials, such as paving slabs, sheets of corrugated iron or a strong root barrier fabric. Ensure the barrier sits above soil level.
- Plant the bamboo so the rootball sits below the top of the trench. Back fill with soil and well-rotted manure or compost, taking care not to damage the rhizomes. Water well and mulch to hide the barrier which is proud of the soil surface.
Advice for buying bambooHere’s our guide to buying the right bamboo for your garden, including how to choose bamboos for screening, low-maintenance bamboos and where to buy bamboos.
- Bamboos are available from garden centres and nurseries, as well as specialist nurseries. Bear in mind that you may get more choice if you buy your bamboo from a specialist nursery.
- Research the height and spread of your bamboo, whether it's clumping or running, and if it's suitable for your size of garden. Bamboos suitable for screening a wall or building will be labelled 'screening bamboo' or similar.
- Ensure the culms have a consistent colour. Look at the new growth and make sure the circumference of each new culm is greater than that of the previous year's – this will indicate a strong plant that's increasing in vigour as it grows.

Types of bamboo to grow
Bamboos are popular garden plants, particularly in contemporary design schemes. There's a huge range to choose from. Here, we explain the different types of bamboo, how to grow and maintain them, and how to stop them growing out of control.
Clump-forming Chusquea bamboos are native to the mountains of Latin America. Unlike most bamboos, their culms are solid, not hollow. Varieties include Chusquea gigantea, a huge species that grows to 4m in height and bears thick green culms, and Chilean bamboo, Chusquea culeou. Chusquea bamboos are some of the best bamboos for screening and can be used as a focal point. Large gardens only.
Clump-forming Fargesia make popular garden bamboos, usually developing into small clumps. Native to the mountains and alpine forests of East Asia, they're some of the hardiest bamboos available. Fargesia murieliae 'Luca' grows to only 50cm in height and is one of the best bamboos for growing in a pot.
Himalayacalamus is a genus of clumping bamboo, native to the Himalayas. It includes Himalayacalamus hookerianus (pictured). Its young culms are blue with a hint of red or purple, maturing to gold. Perfect for growing as a focal point to show off its colour.
Sibataea is a genus of short-growing bamboos, with dark green leaves. Perfect for growing as tall ground cover or a short hedge, it include ruscus-leaved bamboo, Shibataea kumasaca, a dwarf species with gold-tinged leaves.
Thamnocalamus bamboos are clump-forming and native to the Himalayas, Madagascar and South Africa. They include Thamnocalamus crassinodus, which has pale blue culms that become tinged with red as they mature, and tiny leaves.
Phyllostachys is a genus of Asian running bamboos, with most species native to China. Easily identifiable, the culms have a distinctive groove, called a sulcus, which runs along the length of each segment. Many species spread aggressively by underground rhizomes, and can cause problems in the garden. Some species grow to 30m in height. Many Phyllostachys have decorative culms and are perfect for growing as a focal point or a screen. Phyllostachys nigra (pictured) is a a popular choice for gardens, due to its black culms and is often called black bamboo.
Known as broad-leaved bamboo, Sasa is a genus of running bamboos. It includes Sasa palmata f. nebulosa, a tropical Japanese bamboo with yellow culms, and Sasa kurilensis (pictured), which is the most northern bamboo in the world and is therefore extremely hardy. They're ideal for growing in shady gardens.
The only species in this genus is Hibanobambusa tranquillans, a variegated running bamboo with big leaves and a bushy habit. Hibanobambusa tranquillans 'Shiroshima' retains its variegation better than the species, and is perfect for growing as a focal point.
