Managing Overgrown Bamboo: Digging Trenches and Cutting Rhizomes
When you’ve got established bamboo that’s starting to take over its designated space, it’s time to take action. One effective way to control bamboo is by digging a trench around the plant. This trench should be around 30 centimeters deep and at least 30 centimeters away from the bamboo. This creates a physical barrier that helps contain the plant’s aggressive spread. As you dig, cut through any rhizomes you encounter in the trench and remove any that have ventured beyond it. This step is crucial because those rhizomes are the underground stems that allow bamboo to grow in new directions.
Permanently Killing Bamboo: The Stump Cut and Herbicide Method
Now, if you’re looking to completely eliminate bamboo so it doesn’t come back, here’s the scoop. The stump cut and treatment method using a tree-killing herbicide is one of the most effective ways to do it. But before you dive in, let me walk you through the process. First, make a fresh cut on the bamboo stump, ensuring it’s clean and exposed. Then, apply the herbicide directly to the cut. For a more visual guide, check out my video where I demonstrate this method in action.
Natural Ways to Eliminate Bamboo
For those who prefer natural solutions, you can effectively kill bamboo by using heat and light deprivation methods. These techniques are all about stressing the bamboo until it can’t survive. A simple yet powerful method is using boiling water. Here’s how it works: Pour boiling water directly onto the bamboo shoots. The heat damages the plant’s structure and weakens it over time. This method requires consistency and patience, but it can be incredibly effective.

Step-by-Step Guide to Removing Bamboo
Starting from the edge of the bamboo patch, use a mattock to dig toward the center. If the bamboo is particularly stubborn, you might need to use an axe or the cutter side of the mattock to divide the clump as you go. If it’s clumping bamboo, you’ll eventually reach the core of the plant, which is often a dense mass of rhizomes. At this point, you’ll likely need to put in some extra effort to break it apart.
Targeting Pesky Bamboo: Cutting Canes and Treating Hollows
For especially pesky bamboo plants, cut the canes as close to the ground as possible. Once the canes are down, pour a tablespoon of undiluted Roundup® Weed & Grass Killer Super Concentrate into the hollows. This herbicide works its way into the plant’s root system, weakening it from the inside out. It’s a bit of a brute-force method, but it gets the job done.
Digging to Expose Bamboo’s Root System
Digging up the soil to expose the network of rhizomes is another way to tackle bamboo. This method involves physically removing the plant’s root system, which is key to ensuring it doesn’t regrow. While this can be labor-intensive, it’s one of the most reliable ways to fully eradicate bamboo. Follow these steps consistently, and you’ll see results over time.
Understanding Invasive Bamboo and Its Impact
Let’s talk about why bamboo can become such a problem. Running bamboo, like Phyllostachys species, is notorious for its aggressive spreading behavior. These types of bamboo can quickly invade gardens and neighboring properties, causing headaches for homeowners. It’s important to identify which species of bamboo you’re dealing with, as this will influence your approach to managing or removing it.
Preventing Bamboo from Spreading
If your neighbor’s bamboo is encroaching on your property and they’re not interested in addressing the issue, you’ll need to take matters into your own hands. One option is to install a physical barrier between your yard and theirs. This could be a trench or a specialized rhizome barrier. The goal is to stop the bamboo’s rhizomes from crossing over into your space.
Timing Is Everything: The Best Season to Target Bamboo
Here’s a tip: New bamboo culms, which look like asparagus spears, only sprout in the spring. This makes spring the ideal time to tackle bamboo. Wait until the shoots are about a foot tall, then either cut them off at the base or push them over with your foot. They won’t grow back if you catch them early enough. Afterward, cut all mature canes down to the ground. This two-step process weakens the plant and prevents it from spreading further.

Natural Alternatives to Chemical Herbicides
For those seeking a natural alternative, distilled white vinegar is a great option. Vinegar’s high acidity makes it an effective killer of new bamboo growth. Simply apply it to the shoots as soon as they appear. If your bamboo grows in clumps, you’re lucky—these types don’t have the extensive underground rhizome systems that make eradication so challenging. Stick around and use our guide to learn more about how to get rid of bamboo naturally.
Controlling Bamboo Spread Through Consistency
Consistency is key when it comes to killing bamboo. Whether you’re using herbicides, natural methods, or physical removal, you need to treat the bamboo regularly to ensure full eradication. Here are some methods to try:
- Herbicides: While herbicides won’t fully kill regrowth, they can prevent new shoots from emerging.
- Boiling Water: Pour boiling water directly onto the shoots as soon as they appear.
- Mowing: Regular mowing can weaken the bamboo’s rhizomes over time.
- Sawing: Use a saw to cut through thicker bamboo shoots and rhizomes, though this requires digging around the roots for access.
Frequently Asked Questions About Bamboo Removal
When Is the Best Time to Kill Bamboo?
New culms grow between March and May, making spring the best time to target bamboo. This is when the plant is most vulnerable.
How Much Does Professional Bamboo Removal Cost?
The cost of professional bamboo removal varies depending on your location and the extent of the bamboo infestation. On average, homeowners pay between $425 and $1,850 for bamboo removal services.
Is It Safe to Use Herbicides Near Other Plants?
When using herbicides, always follow the product label instructions carefully. Some herbicides can harm nearby plants, so it’s important to apply them selectively and avoid overspray.
Can Animals Help Control Bamboo?
Animals like cows, horses, sheep, and goats generally won’t eat bamboo leaves or shoots, so relying on livestock isn’t a practical solution.
Will Overwatering Kill Bamboo?
Overwatering can kill potted bamboo, but bamboo planted in the garden is much more resilient. Simply running water over a clump won’t have much effect. To truly eliminate bamboo, you’ll need to address the root system.
Permanent Bamboo Removal: The Final Steps
To permanently remove bamboo, start by cutting the plant as close to the ground as possible. Then, dig around the plant to expose the roots and pour boiling water directly onto them. As you dig, make sure to cut the underground stems (rhizomes) and remove them with a digging fork. Repeat this process as needed until the bamboo is completely eradicated. If you’re looking for a cost-effective solution, consider the berm and trench method, where you dig a trench around the bamboo to sever any straying rhizomes. With persistence and the right tools, you can reclaim your garden from even the most aggressive bamboo.
