How Do I Stop Bamboo From Growing Under My Fence? Effective Solutions and Tips
Bamboo can be a beautiful plant, but it can quickly become a nuisance, especially when it starts creeping into your yard from a neighbor’s property. If you’re dealing with bamboo growing under your fence, it’s essential to take action before it takes over.
Installing a barrier, like a deep trench or a strong plastic barrier, can effectively stop bamboo from spreading.
It’s important to know that bamboo grows through rhizomes, which spread underground. By creating a barrier that is at least 28 inches deep, you can hinder these rhizomes from moving into your space.
Keeping the bamboo in check will not only protect your garden but can also improve the overall look of your yard.
With the right methods, you can enjoy your outdoor space without worrying about bamboo invading it. Let’s explore effective strategies to manage bamboo and ensure your yard remains your oasis.
Understanding Bamboo Growth

Bamboo is a fast-growing plant that can easily spread and invade your garden. Knowing the types of bamboo and how they grow will help you manage their spread effectively.
Types of Bamboo: Clumping vs. Running
Bamboo can be categorized into two main types: clumping and running.
Clumping bamboo grows in tight clusters. It spreads slowly, typically remaining within a few feet of its original location. This makes it easier to manage.
Running bamboo, on the other hand, can rapidly spread through underground stems called rhizomes. These can extend up to 15 feet in a single growing season. If you have running bamboo, it can easily invade your garden and neighboring areas if not controlled.
Knowing which type you have is essential for effective management.
How Bamboo Rhizomes Contribute to Spread
Bamboo rhizomes are key to its growth and spread. These underground stems can grow horizontally and sprout new shoots.
Once planted, running bamboo can quickly cover a large area. Rhizomes allow the bamboo to thrive even after cutting down the visible stems. If you’re dealing with this type, you might need more than just trimming.
To control the spread, consider installing barriers that are at least 50 cm deep. This way, you can prevent the rhizomes from pushing under your fence. Other options include applying herbicides specifically designed for bamboo to tackle the problem effectively.
Preventative Measures for Bamboo Spread

When dealing with bamboo, you want to control its spread to protect your garden and fences. There are effective methods you can use, including choosing specific bamboo species, implementing physical barriers, and practicing root pruning. Each method plays a crucial role in containing bamboo and preventing unwanted growth.
Choosing the Right Bamboo Species
If you’re considering planting bamboo, start by selecting the right species. Some bamboo varieties spread much more than others.
For example, clumping bamboo grows in tightly packed clusters and spreads slowly. This makes it a great option for landscaping without worrying about invasiveness.
In contrast, running bamboo can extend its rhizomes far and wide, often invading other areas of your garden. Before planting, research the species that suit your landscape and ensure they fit your space and growth expectations.
Choosing the right bamboo can save you a lot of trouble later.
Implementing Physical Barriers
Using physical barriers is an effective way to control bamboo’s spread. A rhizome barrier, or root barrier, can help keep the bamboo contained within a specific area.
You can create a barrier by digging a trench at least 28 inches (71 cm) deep and installing a sturdy material like plastic root barrier. Make sure the barrier is buried at a distance of at least 2 feet (61 cm) from your bamboo. This distance helps prevent any rhizomes from popping up outside the intended area. Regularly check the barriers to ensure they remain effective.
Strategies for Root Pruning
Regular root pruning can help you control bamboo’s growth and prevent it from spreading under your fence.
To begin, you should locate the rhizomes that grow horizontally. You can use a sharp spade or garden fork to cut through these rhizomes.
Aim to do this at least once a year, especially during the growing season. Regular pruning will keep the bamboo’s size manageable and reduce its chances of invading other areas of your garden.
Remember to keep an eye on new growth and prune as necessary to maintain control.
Methods to Remove Unwanted Bamboo

When dealing with unwanted bamboo, you have a couple of effective options. You can choose chemical treatments or explore natural removal techniques. Each has its own benefits and can help stop bamboo from taking over your yard.
Using Chemical Treatments Safely
Chemical treatments can be very effective for getting rid of invasive bamboo. One popular choice is glyphosate, a non-selective herbicide.
You can apply it directly to the leaves and stems of bamboo plants. This method attacks the bamboo roots and rhizomes.
Make sure to follow the instructions on the label carefully.
Timing is important, as applying glyphosate to actively growing bamboo works best. You may need to reapply after a few weeks for maximum effect, as it often takes multiple applications.
Always wear gloves and protective clothing when using chemical treatments.
It’s also smart to avoid applying on windy days to prevent drift onto desirable plants. Remember to keep pets and kids away from treated areas until they’re safe to enter again.
Natural Removal Techniques
If you prefer not to use chemicals, there are natural ways to remove bamboo.
One effective technique is to dig up the bamboo rhizomes and roots. This may take time, but it’s a safe and eco-friendly method.
Start by digging around the base of the bamboo. Ensure you remove all the rhizomes, which can spread quickly if left behind. After digging, consider planting a bamboo root barrier to prevent regrowth.
Another natural method is smothering the bamboo with tarps. Covering the bamboo can block sunlight and slow its growth over time. Monitor the area closely, as bamboo can still spread under the tarp.
Regularly cutting or mowing new growth can help keep unwanted bamboo in check too. This technique works best on younger shoots and can reduce the plant’s energy to grow.
Maintaining and Monitoring Your Bamboo
Keeping your bamboo in check is key to preventing it from growing under your fence. Regular maintenance can save you a lot of trouble later.
1. Monitor Bamboo Growth:
Frequently check for new bamboo shoots. They can pop up unexpectedly, so keep an eye on your bamboo patch.
2. Trim Regularly:
Cut back any excessive growth. This helps maintain the shape and stops it from spreading too far. Use sharp tools for a clean cut.
3. Install Barriers:
Consider installing an open-sided barrier around your bamboo. This helps contain the roots and limits their spread. You can use wood, metal, or even plastic.
4. Water Wisely:
Over-watering can encourage bamboo spread. Make sure to water based on the specific needs of your bamboo type. Less water means slower growth.
5. Check for Damage:
Inspect your barriers for signs of wear or damage. Replace any sections that seem weakened to ensure they keep the bamboo in check.
6. Keep the Area Clear:
Remove debris and weeds around the bamboo. A tidy area makes it easier to spot any new shoots that may arise.
