Remove bamboo for cuttings
Learning how to remove bamboo rhizomes and culms is quite easy. But the hardest part is digging up the bamboo if you have an old plant in a pot or container, or in the garden. It is labour-intensive and back-breaking work you have to do to get the cuttings you want to re-grow.
From experience, it took over 2.5 hours to dig up the running bamboo rhizomes in an area that is 4 m (L) x 0.2 (W) x 0.2 (D).
On average, it can take 2 – 4 hours or longer to dig up an area that is 1 m (L) x 1 m ( W) x 0.5 m (H) area using a pickaxe if you are working alone.
If you want to remove bamboo in an area that is more than 5 cm2, you should not do it yourself as it may take a lot more effort than you think. Definitely, ask for help or get it done professionally.
Tools: You will need a pickaxe, a pair of secateurs or garden looper, a garden rake, and a hoe.
Best hand tools for removing bamboo
As a rule of thumb, try to do a clean cut at an angle of 45 degrees as this will make it easy to push the cutting into the soil. It can also promote the growth of new bamboo buds or shoots.

How to cut rhizomes for propagation
Bamboo rhizomes are, in fact, underground stems. The runner bamboos grow rhizomes that run horizontally along the ground, whereas the clump-forming bamboos form clusters of clumps at the base of the main plant.
Here is how to remove bamboo rhizomes of Running and Clumping bamboos:
- Select the rhizomes that have buds or shoots coming out at the nodes.
- Put the straight into shade or bucket of water.
- For Runner bamboos cut 4 – 6 nodes or 3 – 5 internodes off the rhizome.
- If you are working with Clump-forming bamboos, separate the compact clumps with 2 – 4 bamboo canes/culms on the cuttings.
- Re-grow the rhizome cuttings immediately.
Tool: You will need a sharp pair of secateurs or garden loppers for snipping the branches and cutting the rhizomes. B&Q has a great collection of cutting and pruning tools – check them out.
When taking the bamboo cutting off the mother plant, do not disturb any new buds and small roots on the cuttings. Put the cuttings in shade or into a bucket of water so that the roots remain fresh for re-planting.
How to cut bamboo culms to grow
Care should be taken when cutting bamboo culms. The new splits and edges are razor-sharp. A cut to the skin can be nasty.
You can grow both the Running bamboos and Clumping bamboos from the cuttings.
Here is how to cut bamboo stems for propagating in pots and containers or in the garden.
- Select bamboo stems that are older than 4 years with a diameter of at least 2 cm.
- Always cut the culms (stems) at 45 degrees with a hacksaw. Allow for two culm nodes and one internode. See the diagram.
- Put the cuttings in water or shape to keep them fresh.
- Plant the cuttings in designated pots or in nutrient-rich soil, away from direct sun. Cover the nodes of the new cuttings with soil and mulch.
- Leave the top of the cuttings covered, free from any soil or mulch.
Tool: You will need a handsaw to cut the bamboo stems. A hacksaw, sharp long-handled or blade knife can also do the job.
Remove bamboo without chemicals
The rhizomes (and clump base) of many bamboo plants in the UK do not grow deep into the soil. They grow horizontally along with the top layer of the dirt at an average depth of 5 – 20cm. If you are going to re-grow the cutting, avoid using chemicals that can potentially damage the parent plant and the cuttings. (Read about the 4 Natural Ways to Kill Bamboos Permanently)
When removing invasive bamboo, always work smart, not hard. Take note of where the rhizomes are running before digging. Here is how to remove bamboo without using chemicals.
- Cut the bamboo stems at 180 degrees across (horizontally), close to the ground. (Remove the bamboo or use them in the garden)
- Dig a drain around or along with the bamboo to a depth of 5 – 20cm.
- Remove the soil and dirt, cut off the rhizomes and clean the root hairs.
- Removing rhizomes: Identify which way the rhizomes are running or how the clumps are formed, and dig along the rhizomes to remove them. (Do not break the rhizomes as they will grow back if left in the soils).
- Removing bamboo base clumps: Use a pickaxe to remove the base of the bamboo – one base stem at a time.
- Use a pair of secateurs or garden loppers to cut the nodes into smaller pieces about 1 – 3cm.
- Remove any side buds and root hairs to avoid any chance of growing back.
- Leave the rhizome cuttings in direct sunlight and starve them off water and shade for 3 – 5 days or unit the rhizomes turn brown. This should be enough to kill them completely.
Tools you’ll need: A hacksaw, pickaxe, pair of secateurs or garden loopers
The bamboos have tough rhizomes (underground stems) and culms (stems). The cuttings are likely to lacerate exposed skins. Take extra care when cutting them.

- Caution: The hardy splinters and edges of the bamboo stems are razor sharp.
- Cut to the exposed skin is highly likely.
