Introduction
Hey there, fellow garden enthusiasts! So, if you’ve been enjoying your outdoor space in South England, you might have stumbled upon a rather unwelcome guest: bamboo. While it may seem like a trendy addition to your garden, some bamboo varieties can turn into real troublemakers. Today, we’re diving into the world of bamboo, identifying the naughty varieties wreaking havoc in our beautiful region, and discussing how to manage these green fiends effectively!
What’s the Fuss About Bamboo?
Now, I know what you’re thinking. Bamboo looks pretty gorgeous swaying in the breeze, doesn’t it? But here’s the kicker: not all bamboo is created equal. There are certain varieties that are the equivalent of the party crasher who just won’t leave. These invasive types can spread like wildfire, taking over your garden and choking out your beloved plants. You might be feeling a bit overwhelmed, but don’t fret! We’ll break it down together.
Common Bamboo Varieties Invading Our Gardens
Let’s get to know the main culprits causing chaos across South England.
Golden Bamboo (Phyllostachys aurea)
This cheeky little number is known for its vibrant yellow stems and rapid growth. It’s a clumping bamboo, which means it spreads out quickly and can become rampant if not contained. You might think it’s cute now, but it can easily turn into a monster if left unchecked! It can grow up to 5 meters tall and quickly dominate gardens and wild areas if not properly managed.
Black Bamboo (Phyllostachys nigra)
With its striking black canes, this bamboo is a popular choice for many gardens. However, don’t be fooled! It can spread aggressively, sending out rhizomes that invade neighbouring flower beds if not managed properly.
Arrow Bamboo (Pseudosasa japonica)
Don’t let its unassuming name fool you! This hardy bamboo sports elegant dark green leaves and tall, straight canes, giving it a rather refined appearance. But beneath the surface, things are a little more… rambunctious. Its extensive rhizome network enables it to spread rapidly, making it a common invasive species in UK gardens
The Environmental Impact of Bamboo Invasions
You might be wondering, “What’s the big deal?” Well, bamboo can dramatically alter local ecosystems. As it spreads, it can outcompete native plants for resources, leading to a decline in biodiversity. Birds and other wildlife that rely on native species may find their habitats shrinking, and that’s not something any of us want to see!
Managing and Controlling Bamboo: Tips and Tricks
Alright, so you’ve identified the bamboo villains in your garden. Now what? Here are a few handy tips to manage these pesky invaders:
- Physical Barriers: Install rhizome barriers to contain their spread. Bury heavy-duty plastic or metal sheeting at least 60cm deep around the bamboo roots.
- Regular Maintenance: Keep an eye on your bamboo. Regularly prune back any runaway shoots to maintain control.
- Chemical Solutions: If things have gotten out of hand, you might need to consider herbicides. Be sure to leave this to the professionals, seek professional guidance and help with any chemical solutions.
- Digging it Out: For the brave-hearted, digging out bamboo roots can be an option, but it’s essential to get every last bit to prevent regrowth.
Important Notes
Distinction between “Clumping” and “Running” Bamboos: Clumping bamboos are generally considered less invasive as they don’t spread as rapidly or far through underground rhizomes. However, even some clumping types may become invasive in certain conditions. The four species mentioned above are all running types and therefore pose the biggest issue.
Control can be Difficult: Once established, these invasive bamboo varieties are very challenging to eradicate and can take multiple treatments and years of vigilance. This often requires professionals specialised in weed control.
Preventative Measures: The best approach is to prevent their spread in the first place by choosing to plant non-invasive species, planting bamboos in containers to restrict their rhizome growth and carefully managing any existing bamboos.
Conclusion
So there you have it, folks! Bamboo can be a beautiful addition to your garden, but certain varieties pose quite the challenge. By identifying these troublemakers and implementing some control strategies, you can keep your outdoor oasis thriving. Remember, it’s all about balance in our gardens, and knowing what to look for is half the battle. So, arm yourself with this knowledge, and let’s keep those bamboo bandits in check!

Answer
In the UK, several bamboo varieties can become invasive if not properly managed. While bamboo is not officially classified as invasive by law in the UK, many species can spread beyond their intended growing area if left unchecked. The most common invasive bamboo varieties in the UK can be categorized into two main types: running bamboo and clumping bamboo.
Running Bamboo Varieties
Running bamboo is generally more problematic and invasive than clumping bamboo. These varieties spread through underground rhizomes that can extend up to 30 feet, potentially causing damage to structures and crossing property boundaries13. Common running bamboo varieties in the UK include:
- Phyllostachys: This genus includes several invasive species, such as:
- Phyllostachys nigra (Black Bamboo)
- Phyllostachys aurea
- Pseudosasa japonica (Arrow Bamboo): A large, fast-growing species that can reach heights of up to 8 meters2.
- Sasa and Sasaella: These Japanese bamboo varieties can produce spreading clumps of stems reaching about 2 meters in height4.
- Bashania: Less common in the UK but can grow up to 7 meters tall and become invasive in warm, moist conditions4.
- Other running varieties include Arundinaria, Hibanobambusa, Chimonobambusa, Pleioblastus, and Sinobambusa15.
Clumping Bamboo Varieties
While generally less invasive than running bamboo, clumping varieties can still spread beyond their initial planting spot under favorable conditions6. Some common clumping bamboo varieties in the UK are:
- Fargesia: This genus includes several popular varieties, such as:
- Fargesia nitida (Chinese Fountain Bamboo)
- Fargesia ‘Red Panda’ (Umbrella Bamboo)
- Bambusa: Various species within this genus can be found in the UK.
- Thamnocalamus: Another clump-forming genus present in the UK.
It’s important to note that even clumping bamboo varieties can become problematic if not properly managed. The Royal Horticultural Society (RHS) states that there are no truly non-invasive bamboo types1. Therefore, regardless of the variety, it’s crucial to implement proper containment measures and regular maintenance to prevent bamboo from spreading uncontrollably and potentially causing damage to property or neighbouring gardens.
