I love bamboo trees in my garden, but sometimes they can spread more than I want. So I researched to find out how deep are bamboo roots, also how fast bamboo roots grow and how to stop them from becoming invasive.
Follow along, and I will describe everything in depth below.
How Deep are Bamboo Roots
There are, of course, some exceptions, but virtually all varieties of bamboo that are widely used in gardens do not extend further than three feet. The rhizomes will never reach a depth of 12 inches.
Bamboo roots typically reach a depth of about two to three feet. The roots are thin. The actual rhizomes, on the contrary, don’t extend that far. They typically range from 10-12 inches in depth. This makes removing or controlling the bamboo easy by putting up a shallow barrier.
If you want to control your bamboo, constructing barriers around the bamboo is the best choice.
Dig a 12-inch ditch around your bamboo. Cut off all the rhizomes and roots and place barriers within the trench before re-burring.
If you’re trying to rid yourself of growing bamboo in your garden, the most efficient method is to cut it back and dig out all the rhizomes.
This may seem like a lengthy and laborious process I believe it’s the most efficient and secure method to eliminate bamboo.
There are, of course, numerous methods and products claimed to assist in getting rid of bamboo. For instance, hot water is just one of the methods, but I’ve personally had mixed results. It all depends on the bamboo’s age, type, and variety.
If you are looking for the most reliable method to eliminate bamboo, removing the rhizomes is the most effective method.
To eliminate all the rhizomes, trim the bamboo to the back.
Start digging into the rhizomes using the help of a shovel. Rhizomes do not have very deep roots, and you’ll be able to root them quickly.
It is important to dig around twelve inches (30 cm) in the area where the bamboo began to grow, as the rhizomes may have spread far away from the bamboo.
Spend time searching for the Rhizomes. If you don’t find one, your efforts will be in vain.
Do not throw your rhizomes in the compost because bamboo will grow there.
How fast do bamboo roots grow?
Another concern people face is when they hear that bamboo has to be controlled by installing barriers that stop the rhizomes from spreading outward.
It is impossible to see how quickly the roots develop, and many gardeners who are hobbyists are frightened when they see an area of bamboo in their gardens.
I experienced the exact issue in my garden, where there was only one plant, and we left it alone. Then, one year later, the same lonely bamboo was not so lonely anymore. To help you to determine if you’d like to build barriers or even remove the bamboo entirely.
Bamboo roots can expand quickly if left unchecked. Based on your Bamboo species, it will be spread out between 1 to 5 feet per year. Bamboo has a complex root system that produces many shoots. This means that a single division of bamboo can grow between two and six feet per year.
These numbers are pretty general and depend upon your growing area and the types of bamboo you can find on your property.
There are also aggressively expanding bamboo varieties that aren’t typically found in the US, which is a blessing. Most of the varieties grown in the US don’t spread more than 6 feet per year.
I hope that this article will aid you in deciding what to do when you see a bamboo plant in your backyard or may assist you in deciding whether you would like bamboo in your garden or not. What are your options if you decide to include some bamboo growing in your garden? would you like to stop it from growing?
We didn’t react to our bamboo in any way, and after a year, we discovered a huge bamboo patch growing in our yard. It was necessary to construct barriers to prevent them from spreading into the neighbor’s property. We’ll for now leave the bamboo there however, if it grows and gets too high, we’ll likely eliminate it or manage it with a thicker barrier.
I highly suggest acting immediately If you spot bamboo and you’ll have the same issues as us. It was difficult to construct barriers when the bamboo was expanded to the point of no return. We were completely unaware of the speed of the bamboo’s spread and how quickly it develops.
It was especially so because it didn’t increase during the first year. In the second year, however, it increases dramatically.

How do you stop bamboo roots from spreading?
Ensure sufficient water if the roots extend out to locate it. This entails not just running a hose next door but also lowering the demand for it.
Reduce the size of the main shrub by eliminating up to a third of the stems, allowing it to live with fewer resources. This keeps the bush clean since you may remove dead or broken stems at the same time.
Mulching can also help to concentrate water on the plant. This maintains the moisture near the plant and prevents it from evaporating.
You may also utilize physical and mechanical barriers, which are all effective. They may not be ideal for the simplicity of maintenance that bamboo gives.
But If the bamboo has already multiplied, the first step is to consider the long-term and eliminate the runners. Limiting its capacity to absorb energy will ultimately weaken and die, just like any other grass. Continue to clip the stems as they appear.
You can also take more drastic actions. You may either cut them or pull them out. They should be extracted using a pitchfork or crowbar, similar to an ax. If the stems appear in locations that cannot be dug up or disturbed, such as under a prize rose bush, this is the strategy to adopt.
Allow the stem to develop until it is at least 6 mm broad. The stem should then be cut off, leaving a stump. Glyphosate herbicide should be applied to this stump. If the stalk grows too big, the liquid will accumulate in the hollow stems and destroy the stolon.
Repeat therapy may be required. There is always the possibility of removing more than just the rhizome you wish to remove.
Dig around the stolon to reveal it and cut near the main plant as feasible in certain circumstances. Avoid spraying herbicide near the plant. It takes a lot more chemical to have the same outcome as if it was allowed to permeate the stem.
When the stem and stolon die, they harden and can typically be taken out.
So to conclude how deep are bamboo roots, as we discovered, they are around 2 to 3 feet deep. However, the growth rate is determined by the growing zone, bamboo variant, and plant age.
If you are planting a bamboo grove, the fastest growth rate will depend on the age and size of the initial planting. This will determine the size of the new shoots.
