If killing bamboo with bleach and gasoline sounds to you like a bad idea, that’s because it is. But sometimes bamboo can spread so aggressively that it will drive gardeners to the point of madness. Rather than going to the trouble of excavating a bamboo plant and removing the entire root system, it’s tempting to look for shortcuts. Necessity, as they say, is the mother of invention. And yes, maybe a stitch in time can save nine. But saturating the soil with toxic chemicals to eliminate some bamboo is more like an example of when haste makes waste.

So, can You Kill Bamboo with Bleach, Gasoline, Salt, or Vinegar?

These substances may damage bamboo foliage and young shoots, but they rarely eliminate an established bamboo grove. In most cases, the underground rhizomes survive and eventually produce new growth. Gasoline and bleach can also contaminate soil and groundwater, while excessive salt can damage the surrounding landscape for years. For permanent removal, physical excavation of the rhizome system remains the most reliable method.

In this article, we’ll consider how effective these various methods might be and spell out the disadvantages of trying to kill off bamboo with poisons and chemicals. We’ll also explain the proper and most effective way to go about removing an unwanted bamboo plant.

Can I kill my bamboo?

When something becomes invasive and starts to take over your yard, your instincts might simply tell you to kill it. Stop the menace before it destroys the entire garden. Bamboo can easily run under the fence and wreak havoc on your neighbor’s garden as well. So there are times when the only solution is to stop the beast in its tracks. But how?

Bamboo is a remarkably sustainable plant, fast-growing and resilient. In agriculture, these are fabulous traits. But when it comes time to remove the bamboo, you’re up against a real force of nature. When you cut it down it grows right back. Those running rhizomes can get everywhere, forming an invincible underground network. The thought of digging them out is simply too much. It sounds so much easier to just kill it off.

But killing bamboo is not easy. Sure, you can sabotage and disfigure it until the once elegant plant has become an unsightly monstrosity. The leaves will discolor and fall, the culms will dry out and deteriorate, but the rhizomes will hang on for dear life. And in most cases, they will gradually recover, and begin to spread once again.

Why is bamboo so hard to kill?

Unlike many weeds, bamboo stores large amounts of energy in its underground rhizomes. Even when the visible culms are cut down or damaged, the rhizome network often remains alive and capable of producing new shoots. A mature grove may contain dozens or even hundreds of interconnected rhizomes beneath the surface, making complete eradication far more complicated than simply removing the stems above ground.

Unconventional methods of bamboo elimination

Given bamboo’s resilience and tenacity, desperate gardeners often resort to desperate measures. Once you’ve cleared away the culms and any of the bamboo growing above ground, you might consider some of these toxic and exotic options.

Killing bamboo with gasoline or diesel

Gasoline is a powerful weed killer. And some gardeners claim that it can be effective in killing bamboo. Once you’ve cut back the poles, they say you can sprinkle or spray a gallon or two of gasoline over the area where the roots are.

Obviously, this is not an environmentally friendly option. And in most neighborhoods, it’s illegal to pour gasoline into your soil. Like dumping toxic waste in your own backyard, this is a technique that we simply cannot endorse.

Killing bamboo with salt

The use of salt to kill off crops is a practice as old as the Roman Empire. Not quite as toxic, but like using gasoline, it can do permanent damage to your soil. Pour enough saltwater on your bamboo, and it will suffer. But whether it will die is probably a question of time and persistence.

One method I’ve seen is to fill a large bucket with saltwater, and then tap into it with your surviving bamboo roots. Simply lift the long and shallow roots up from the soil and place one end in the bucket. Give the roots a few days to drink up some of the saltwater, and then continue throughout the bamboo-infested area.

Some gardeners report success exposing bamboo rhizomes and directing saltwater into them. Results appear inconsistent, however, and the process can require nearly as much effort as simply excavating the rhizomes.

Killing bamboo with Roundup

Attempting to rid their yards of bamboo, it’s not surprising that some gardeners would resort to the world’s most widely used herbicide, glyphosate, popularly sold as Roundup. In addition to the environmental and purported health risks associated with this toxin, most people agree that it’s simply ineffective against bamboo.

I don’t use this product myself, but according to many who do, it only works to kill off a few shoots at a time. Culms will wither and die, but the roots live on, and it’s only a matter of time before new shoots begin to appear again.

Glyphosate can kill actively growing bamboo foliage when applied correctly, but established bamboo often survives because extensive rhizome networks store significant energy reserves underground. Multiple treatments are usually required, and even then, complete eradication is not guaranteed.

In my opinion, the questionable efficacy does not justify the potential health risks.

Killing bamboo with bleach

I’ve seen people pour bleach on unwanted plants, in a mix of desperation and ignorance. Frankly, I cannot attest to the efficacy of this technique, having never tried it. But the overwhelming consensus is that it does not work on bamboo. And like the use of gasoline, this is basically equivalent to dumping toxic waste in your garden. You wouldn’t throw batteries and old lightbulbs in your compost, and neither should you pour bleach into the earth.

Killing bamboo with vinegar

Another option available in most pantries, vinegar can definitely kill a small house plant. But will it kill your bamboo? Probably not. Vinegar will basically throw the pH way off, making it too acidic for most plants to survive. But eventually, the soil will adjust, and the bamboo will recover.

Like a lot of these methods, it’s only a matter of time. So you end up in a war of attrition with the bamboo. How long do you want to keep pouring herbicides, bleach and salad dressing into your garden, before you finally give up and grab a shovel?

More effective ways to remove bamboo

Really, the only effective way to permanently eliminate a bamboo plant is to excavate the entire root system. Begin by cutting all the culms down to the ground so that the dirt is accessible to shovels and pickaxes. Then start digging. If you’re dealing with a large area of bamboo, you may need to use a backhoe. Remember to be thorough. A small, surviving section of rhizome could be enough to bring the whole grove back.

Sorry to say it, but basically we’re talking about bulldozers and elbow grease.

See our detailed article on How to get rid of bamboo.

I’ve heard other gardeners say that covering their bamboo stumps with thick, black plastic tarp to starve them of water and sunlight will also kill the plant. Personally, however, I’m a bit skeptical. You’d have to cover a pretty wide area, to ensure that the roots don’t just come up around the edges. And you’d have to be comfortable with a giant sheet of plastic buried in your yard.

Frankly, every time I’ve seen someone use a plastic tarp to keep weeds out, the tarp has eventually disintegrated. Maybe it works for a few years, and maybe even enough time to sell the house and move away. But eventually you (or the next resident) end up with all these little bits of shredded plastic mixed in with the mulch or rocks or whatever went on top of the tarp.

Consider the asem approach, but without the tarp. Persistent cutting and removal of new shoots can eventually deplete the rhizome system. The process may take multiple growing seasons, but at least it won’t leave a legacy of plastic litter.

Of course, it always helps to have the right tool for the job. That’s why we recommend these carbon steel shovels with serrated edges from Radius Garden. The Root Slayer, available from Amazon, comes in a few different sizes, ideal for eradicating those hard-to-reach rhizomes.

Prevention and planning

Don’t be put off by the fact that some bamboos can be agressive or invasive. There’s actually a wide variety of clumping bamboo species, which keep to a pretty confined area. If you stick with these types of bamboo, you won’t run into the problem of running bamboo taking over your garden and your neighborhood.

Otherwise, it’s always a good idea to use a bamboo root barrier, such as Bamboo Shield, shown above and available from Amazon. These thick, plastic barriers go about 2-3 feet deep into the ground and contain the running rhizomes quite nicely. Just give the bamboo enough room within the barrier to stretch out. And be sure to check around the barrier once in a while to look for jumpers and runaway rhizomes trying to escape the barrier. You can never be too safe with these guys.

Take a look at our detailed article on Installing Bamboo Root Barriers.

Another great strategy is to dig a trench around your bamboo grove. This is a safe and reliable method that makes it easy to monitor the rhizome activity and keep the bamboo in place.
