How to stop bamboo spreading?

Disturbing the shoots from growing can inhibit spreading, but does not stop the bamboo from growing back. 

Though it is a temporary measure, it can be effective where bamboo grows in barriers.

 Here is how to stop bamboo from spreading.

Use garden spade and pickaxe

1: To kill bamboo in the garden using hot water, cut the stems as close to the ground as you can, and dig around (and through) the plant to expose the shoots.

Hot water

2: Pour hot water directly on the new shoots and exposed rhizomes, around the base of the bamboo and where there are signs of growth.

3: Repeat the steps if new shoots grow the following Spring.

If you have bamboos that are 2 – 3 years, this method will work just fine. 

Bamboos that are older than 5 years will have well-established rhizomes (in running bamboos) or build-up clumps (in clump-forming bamboos) which make them harder to treat with hot water.

In this case, build a barrier or use the method mentioned above to permanently remove the bamboo.

You will need these tools:

• Pickaxe
• Garden spade
• Hot water
• A pair of garden loppers and secateurs

4 effective ways to stop bamboo from spreading

Although bamboo plants are evergreen and adorable plants adorable, the rate at which they grow can be troublesome. 

They spread aggressively and take up any space that is available very quickly if left untouched for 2 – 3 years. 

One of these methods may be ideal for you.

• Cut stems and dig rhizomes to kill bamboos
• Pour boiling water on shoots
• Cut and burn to kill bamboos
• Apply vinegar

Get all the tips on how to remove bamboo.

Note: Get it done professionally. The work is painstakingly hard.

If you want to do it yourself, here are 4 ways to kill bamboo plants permanently.

Remove running bamboo vs clump-forming bamboo

The work required for running bamboos and clump-forming bamboos is slightly different. 

The running bamboos have horizontal stems (rhizomes) that you have to expose before applying the undiluted white vinegar. 

Whereas the clump-forming bamboo may require cutting and digging around the clump to expose the roots.

• The Running bamboos have an extension of long-horizontal rhizomes, very invasive. 
• The Clump-forming variety forms and expansion of clumped base and grow really thick in clusters.

 

How to dig out bamboo roots using hand tools

Digging out bamboo roots needs planning and the right tools. This article provides all the info you need to know based on the work we did in the bamboo garden over many years. 

Find out how to remove bamboo rhizomes the right way by using hand tools.

Best hand tools for digging up bamboo

Bamboo roots/rhizomes and base buds are rough, you've got to have tougher tools to deal with them. 

The best hand tool for digging out bamboo is a pickaxe. Though it's heavy, it will make work lighter.

Also, you will need a pair of shears, a spade/shovel, a crowbar and a pruning hand saw.

Use a sealable bin to keep the rhizome cutting until they are dry.

Dig out bamboo roots

When digging out bamboo, always do a clean cut through the rhizomes without pulling or splitting because the remaining parts will grow back, quickly.

Also, take precautions when digging up bamboo roots. The bamboo slits are razor sharp and can cause injury.

As a rule of thumb, cut the bamboo roots and rhizomes into smaller segments and keep them in a dry area until they dry before discarding.

Rhizomes and clump bases

Running bamboo rhizomes are underground stems. 

Clumping bamboo plants do not have rhizomes, instead, the roots form clusters around the plants called clump bases. 

Here is how to dig out bamboo rhizomes and clump bases to propagate.

• 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.

Dig out bamboo best non-chemical removal method

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.

When removing invasive bamboo, always work smart, not hard. 

Identify where the rhizomes are running before digging. 

Here is how to dig out bamboo without using chemicals.

Cut stems

• Cut the bamboo stems at 180 degrees across (horizontally), close to the ground. (Dig out the bamboo or use them in the garden)

Dig out dirt

• Dig a drain around or along with the bamboo to a depth of 5 – 20cm.
• Dig out the soil and dirt, cut off the rhizomes and clean the root hairs.

Remove rhizomes and clump bases

• Removing rhizomes: Identify which way the rhizomes are running or how the clumps are formed, and dig along the rhizomes before removing them. (Do not break the rhizomes as they will grow back if left in the soils).
• Removing bamboo base clumps: Use a pickaxe to dig out the base of the bamboo – one base stem at a time.

Do these before binning

• Use a pair of secateurs or garden loppers to cut the stems 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: Hacksaw, pickaxe, pair of secateurs or garden loopers. Get them here 

Work smart when digging up bamboo roots

The bamboos have tough rhizomes (underground stems) and culms (stems), so work smart when digging them up.

Care should be taken when cutting the bamboo stems and rhizomes.

Hope this article gives you an idea about how to dig out and remove bamboo rhizomes in your garden and stop the rhizomes from spreading into other spaces.

How to Get Lots of Bamboo Shoots

New bamboo shoots and rhizomes tips sometimes show signs of distress by turning brown. 

This is a course for concern because the shoots are unlikely to recover. So, what are the main causes of bamboo shoots turning brown?

Maintain soil moisture 

New bamboo shoots and rhizome tips will struggle to grow, turn brown and die where it's too dry.

The browning of bamboo shoots indicates a lack of nutrients and water.

Maintain soil moisture and add fertiliser to promote the growth of the new bamboo shoots and rhizome tips. 

Reduce competition

The new plants in confined spaces like the pots are competing with the old plants for what nutrient is available.

In such competition, the older plants always have the advantage over the new plants because they have well-established clumps or root systems. 

They absorb the nutrients resulting in the browning of the new shoots or rhizome tips.

The best thing to do is to remove the old bamboo stems in early Spring or late Summer to promote new growth. 

The new shoots will be ready in time for the next growing year. (Read about how to cut rhizomes and culms).

Dry summer affected bamboo

The record temperature in the summer of 2022 affected the new bamboo shoots. 

In fact, the matured bamboo plants did okay, but the new shoots that came out that spring turned brown and never recover. 

There was a horse-pipe ban, there was nothing we could do to protect the new shoots.

Interestingly, I added mulch in spring that year and it does wonders to the bamboo. 

Immediately after the dry spell, it rained for 3 days and this video shows what happened towards the end of summer. 

Watch this!

Best soil for growing new bamboo

Although bamboo plants are tolerant to different soil types, the new bamboo plants will need well-drained moist soil to produce new plants.

Improve soil fertility if the soil lacks nitrogen (N), phosphorus (P) and potassium (K).

 

Grow bamboo in soil

New bamboo roots and shoots dislike waterlogged pots, soggy soil and dry-compacted soil. 

So, do not use sandy and porous soil because water passes through quickly. 

Also, avoid using hard and compacted soil high in clay when propagating new bamboo plants.

The best soil to grow bamboos in pots and containers is loamy soil topped with a humus-rich layer 5cm– 10cm. A loam soil that contains a mixture of clay is best for new plants.

Check out where to buy potting mixtures, feeds and fertilizers from top UK suppliers.

How to prepare loam soil

Humus and loamy soil are best for growing bamboo plants in pots. The mixture of clay, sand and silt creates the right condition for retaining moisture without waterlogging and is ideal for growing new bamboo.

 The loam soil is not easily available, but you can make a good mixture using sand, silt, and clay in the ratio of 1 : 1: 1. As a general rule, loam soil should consist of equal parts of all three soil types. For example, 3kg of sand to 3kg of silt to 3kg of clay.

The best time to plant bamboo is early Spring because new shoots and rhizomes grow at this time. 

If you are re-potting an old bamboo plant, make sure that the root hairs and rhizomes remain intact for the plant.

Improve soil for healthy bamboo growth

The first 5 – 12 months of a bamboo’s life in the soil is crucial. This archive of articles has lots of info about how to propagate bamboo plants, check it out.

It will need care and attention, so ensure that the soil remains moist and the condition is perfect for the plants to grow.

The starting points below will help you to create the best soil condition for the new bamboo plants. 

 

Water: 

Bamboo plants in pots will require more water than those grown in the ground. 

Give the plant a generous amount of water, but not too much that it runs out the bottom.

Feed: 

Bamboos in pots need nitrogen-rich organic liquid feed (such as Universal Granule Fertilisers). 

Add mulch such as small barks or grass cutting mixed with small twigs and branches if necessary.

Check: 

No pruning is necessary for the first 12 months after planting your bamboo. 

Check and remove weeds, insects, and dust on the leaves.

Care: 

Monitor the leaves of the bamboo as they are good indicators of the plant’s health.

Soil condition: 

If you think the soil is dry, push a stick or small metal through the top (10cm – 15cm) layer of the soil to check the moisture at different levels.

How to revive bamboo leaves turning yellow - chlorosis

The colours of the bamboo leaves are a good indicator of the plant’s general health.  Like other perennials, the natural colours of the foliage shows that plant is thriving. 

When bamboo leaves turn yellow or curl - or the stems turn brown - it may mean that it needs immediate attention. The yellowing of the leaves is called Chlorosis.

This article suggests how to revive bamboo leaves turning yellow by applying bamboo-saving interventions.

Temperature changes cause yellowing/curling of leaves

Outdoor temperature (Frost): 

Bamboos can withstand temperatures below 0 degrees, they are winterhardy. But extreme cold and frost in Winter can kill the new plants. 

There is little you can do to avoid the weather, however, adding mulch (preferably grass cuttings) to create a humus reach base around your bamboo will protect the plants from the Winter’s cold.

Indoor temperature (Heat):

Bamboos in containers can succumb to indoor heat and temperature fluctuation. 

If the heat is too high or the surrounding heat change abruptly, the leaves of the bamboo plant will roll into a curl to protect themselves from water loss. 

Heat also can cause brownness around the culms (stems). So, keep them in check so that they do not succumb to indoor heat.

Fertilisers with an equal proportion of Nitrogen to Phosphorus to Potassium are ideal for bamboo plants.  The Universal Granules (Slow-release) Fertilisers are ideal for bamboo plants,

Why Do Bamboo Leaves Turn Yellow?

The bamboo leaves turn yellow due to a number of reasons. The common causes of yellowing leaves and curling leaves are stated above. 

In addition, the main causes of distress in bamboo plants are nutrient deficiency, bug infestation, and availability of water.

Here are ways to address the distress in your bamboo plants.

 

Bug infestation: 

It's rare in the UK to see bamboos infected with bugs. But, it is common in tropical areas where bamboo is a native plant. 

Perhaps, it is important to check for spider webs and wasp nests in the leaves. 

For indoor plants, make sure the leaves are dust-free. 

What gathers on the leaves disturbs them from getting enough sunlight and eventually slows the rate of photosynthesis which can lead to an unhealthy plant.

Moisture stress:  

Lots of water or no water in the soil is another common cause of yellowing bamboo leaves. 

Check the top layer of the soil to a depth of 5 cm - 10 cm.  

Dig or dip a bamboo stick into the soil and check the moisture present in the soil. Water the plants generously, even in Winter.

Chlorosis of bamboo leaves

Chlorosis is the yellowing of leaves in plants due to a number of reasons such as temperature variations, bug infestations and moisture stress.

Other factors that are likely to cause chlorosis of bamboo plants include:

• poor drainage, 
• damaged roots, 
• compacted roots, 
• high alkalinity, and 
• nutrient deficiencies.

How to improve soil nutrient content (Bamboo-saving interventions)

If you realise that bamboo leaves turn from green to pale yellow, it indicates that they are low on nitrogen, phosphorus and potassium.

Do not remove the yellow leaves or cut the plant.

Apply fertilisers or a recommended plant feed high on N, P and K once or twice a year, ideally in early Spring.

In fact, adding NPK fertilisers will improve the growth of new shoots and leaves in the next growth year. Your bamboo will, once again, produce healthy rhizomes, shoots and leaves.

Revive bamboo leaves curling

Bamboo leaves curling inwards happens as a result of two things: either there are bugs camping in the leaves or it’s too hot for the plants.

Some spiders and wasps build webs and nests using the leaves as cocoons. Usually, insects will use a few leaves, even one, to nest and cause no harm to the leaves.

The main cause of curling leave is heat.

Bamboo leaves are thin and elongated, they lose a lot of water through transpiration. If it is too hot, the leaves curl inwards to protect themselves from high water loss.

To revive the curling bamboo leaves, give them enough water. Move the potted plants to windowsill or outdoors for the leaves to unfurl.

Yellow leaves on bamboo fall off

Bamboos are a tough group of plants, their leaves are quite tough the plants. 

The leaves grow to full length and strength at about the same time as the main bamboo and live as long as the bamboo is standing.

When the leaves fall off, it could mean the bamboo is old. Cut the culms so that new shoots will grow. 

However, you should be concerned if the leaves start to fall off a plant that is 5 years old or younger. It means the soil is lacking nutrients.

Check the soil and condition of the plants. Applying one of the methods discussed above to revive them.

How to take care of a bamboo plant [Soil, Water, Light, Fertiliser]

Bamboos are versatile plants. They can withstand a range of dry and cold conditions in their natural habitats. 

However, they are susceptible to prolonged dry soils, very high and cold temperatures, compacted soils and, generally, neglect.

How to take care of a bamboo plant [Soil & Water]

To keep your bamboo plant thriving throughout the year, check for the following needs.

Soil:

Bamboos are not fussy about soil, but it is always a good idea to check the soil where they are growing and ensure that the soil is able to support the plant.

If the soil is too low in nutrients, or too compacted, the bamboo leaves will turn yellow and eventually fall off the plant.

Water:

Check that the soil is moist, but not waterlogged. Add mulch and grass cuttings with small barks or bamboo leaves around the plant.

 Check out the list of top UK Home & Garden suppliers for all you gardening needs.

Bamboo plant care – general checks

Plants' care and checks are important for ensuring that your plants are healthy. Check that your plants have enough nutrients, water, and light.

If you are growing bamboo in pots and containers, lay the top area with mulch or pebbles.

Waterlogged soil will cause stress to the rhizomes and root hairs which will eventually affect the whole plant including the leaves.

How to take care of a bamboo plant [Light & Fertiliser]

Light:

Some bamboo varieties prefer lots of sunlight, others like partial shade or shade. Many nurseries and garden centres provide this information when you buy the plants.

So, grow your bamboo in the right location so that they provide the evergreen foliage throughout the seasons.

Fertilizer:

Bamboo leaves are the best fertiliser as they contain Silica which the bamboos need in large amount. Rake the leaves and put them under your bamboo plants.

They also require nitrogen, adding NPK fertiliser will also help your bamboos grow strong.

The factors that are likely to improve the growth of the bamboo plants include:

• good drainage, 
• well-established roots,  
• neutral alkalinity, and 
• good soil moisture and
• nutrient-rich soil.

Insects and animals in a bamboo grove

The evergreen thick foliage of bamboo plants is an ideal cover for rats, insects and bugs, especially in the humid and tropical regions of Asia and the Pacific. 

However, in temperate UK conditions, bamboo groves are thriving environments for bees, wasps insects and termites.

They are great nesting sites for mice and smaller rodents. 

Squirrels do love to munch on the new bamboo shoots, too. [See the video] So, cover the new shoots with pots to protect them from the squirrels.
