What should she do about neighbor’s bamboo?

June 19, 2012
bamboo and fountain in Niagara County

Jaime Pabilonia of Youngstown grows bamboo, which can be invasive. He said the sidewalk helps keep it from spreading too much.

From time to time, we post a question and ask for input from our readers. If you have an idea on how to help, please leave a comment.

I hope you can help with a gardening concern I have. My neighbor has bamboo growing in their front yard. Right now it’s sending shoots out into just their yard. However, I’m terrified it will creep into my yard. I’ve read some scary things online about bamboo. Can you tell me how damaging this can really be and if there is anything I can’t do to protect my house from this stuff? It’s an old Buffalo neighborhood where the houses are quite close and the foundations are over 90 years old! Scary thought.
Thanks,
Alissa

Readers, can you help Alissa? Does her neighbor’s bamboo pose a threat to Alissa’s foundation? How should she handle this problem? Please leave a comment below.

  1. Penny on June 20, 2012 at 8:11 am

    First thing that I would do is to talk to the neighbor since running bamboo spreads by rhizomes even a tiny piece leaft behind will start growing and spreading. If talking to the neighbor about your concerns doesn’t work, I have heard that using salt water or rock salt on the emerging bamboo will work. Be aware it will also kill any surrounding vegetation too

  2. Donna on June 20, 2012 at 8:19 am

    I agree with Penny. Running Bamboo is hard to contain, even if planted in restricting containers. It will eventually find your yard.

  3. connie on June 20, 2012 at 9:08 am

    Those are great suggestions. If the neighbor isn’t trying to control the bamboo, it sounds like the neighbor will have a problem soon, too. I had thought of trying to slow down the bamboo by planting it in a pot and placing the pot in the ground, but judging from these comments, that might not be as effective as we’d like. Can bamboo be destructive to the foundation of a house?

  4. Penny on June 20, 2012 at 10:17 am

    yes it can be destructive to the foundation. As those rbizomes spread and reach the foundation it it like so many tree and shrub roots and cause crazing or fissures in the foundation and possible water seepage into the basement or crawl space but bamboo is even more aggressive. Because of its extra fast growth and spread it does make a good and environmentally friendly building material but that is probably its only redeeming grace.

  5. Kirsten Reitan on June 20, 2012 at 11:40 am

    The first thing I would do is find out WHAT KIND OF BAMBOO it is. There is a house on LeBrun in Amherst which has bamboo that is in thick clumps but does not spread the way running bamboo does. Also check to see that it isn’t Japanese knotweed…it looks like bamboo and is highly invasive….it will have white flowers in August/September. I would definitely talk to your neighbor first to find out the kind of bamboo, and then discuss options.
    Hopefully your neighbor is open to solutions.

  6. Kirsten Reitan on June 20, 2012 at 11:57 am

    I found two websites that may be of some help.
    1. The first is from a site that sells bamboo and discusses running vs. clumping. That’s why I mentioned checking which kind you have. Clumpers do spread too, but are not invasive. You need to scroll down a bit to find the section on the two types.
    http://bamboo.home.texas.net/control.html
    2. The second webpage gives suggestions for how to deal with running bamboo. Timing of removal of new shoots and mowing apparently are important.

    Hope that helps.
    Kirsten

  7. connie on June 20, 2012 at 2:01 pm

    Kirsten,
    Thanks for all that information. I talked to someone who had Japanese knotweed in his yard, and it sounds horribly invasive. He had to use a backhoe to get it out.

  8. Penny on June 20, 2012 at 3:11 pm

    Alissa did mention that it is already sending out runners. Clumping bamboo to my knowledge will not send out runners. So that does suggest running bamboo as opposed to clumping bamboo.

  9. Manheim Garden Center on June 21, 2012 at 4:47 pm

    This can cause a lot of problems if it isn’t dealt with quickly. The roots can grow over into your property, even if the stalks themselves don’t.

  10. Michelle Schmitt on July 16, 2012 at 1:03 pm

    Trenching metal flashing will deter for a short while. Bamboo will eventually overcome the barrier. Trenching& then extreme salting have been my best defenses. It leaves the bamboo in a natural clump, while giving definition to the garden. The salt is contained in the trench& also accessible to runners so no salt burns to any other plants.

  11. connie on July 16, 2012 at 3:16 pm

    Thanks for this new idea. How do you keep the salt in the trench?

  12. Michelle Schmitt on July 16, 2012 at 4:08 pm

    I water the trench then salt. The salt sticks to the muddy walls.

  13. connie on July 16, 2012 at 8:26 pm

    I think I’m understanding now. You dig a trench around the bamboo plant. You coat the inner wall, the one closest to the bamboo plant, with salt. Then you add the metal flashing and fill any gaps with soil. The salt may leech downward, but it won’t leech outward because of the metal blocking it from the rest of your landscape. Do I have that right?

  14. Michelle Schmitt on July 16, 2012 at 11:13 pm

    Yes that is how I do it. The metal degrades after a while but I’m usually ready to change things by that time.

  15. connie on July 17, 2012 at 12:22 pm

    Thanks so much for taking the time to explain it. I couldn’t quite picture it.

  16. Alissa on July 17, 2012 at 7:58 pm

    Thanks for all the information. It sounds like I may have to go on defense.

  17. viki on August 11, 2012 at 9:20 pm

    Bamboo growing from your neighbors yard into yours is a criminal trespass. It is also a legal nuisance. It is their financial responsibility to remove the bamboo from your yard, to make sure the bamboo does not trespass in the future, and to return your yard to the condition is was in prior to the invasion. I would start by contacting your city attorney. If she can’t be of assistance then you need a real estate attorney.

  18. connie on August 13, 2012 at 8:26 am

    I hadn’t thought of the bamboo situation that way. It’s another option she can consider. Thanks for writing.

  19. Carol Merritt on October 19, 2012 at 3:48 pm

    I almost bought a house in Virginia where the bamboo had grown through the sidewalk. It had grown up through the expansion joints where the concrete broke and cracked from its own weight leaving room for more bamboo to grow. I am so glad that we never bought that house. At the time I didn’t know what this plant could do. I thought we could just dig it out like any other plant.

  20. connie on October 19, 2012 at 3:52 pm

    Carol, that is amazing! Until a couple years ago, I didn’t even know that bamboo would grow in our area, much less that it was so invasive. Thanks for sharing that.

  21. Carol Merritt on October 19, 2012 at 5:15 pm

    Connie:

    Bamboo seems to grow anywhere. It is as far north as Canada. I have seen it covered with snow and I have seen it growing in sand in a drought. I am sure that it has qualities that some people find valuable, but I think it does not have a place as a landscaping plant in a residential neighborhood. There needs to be laws.

  22. Carol Merritt on October 20, 2012 at 5:30 pm

    Here is a website that will explain all. https://www.facebook.com/InstituteOfInvasiveBambooResearch
    Caryn has been doing research for many years now and has spoken with many authorities on the subject as well as having to deal with the plant on a personal level. The U.S.D.A. is sending people with questions to Caryn. If you need help please call Caryn at 203 734-6344.

  23. connie on October 22, 2012 at 7:41 am

    Carol, that’s very helpful information. I see that there are towns in New York State that have banned the growing of this bamboo. The link you listed is for the Facebook page. The website has even more information: https://sites.google.com/site/invasivebambooresearch/

    I think Alissa will find it helpful.

  24. Carol Merritt on October 22, 2012 at 10:36 am

    There are towns in New York State, Maryland, Delaware, and New Jersey that have already passed ordinances. North Carolina Beach towns are looking to have ordinances passed as well as Connecticut and Massachusettes. This (Phyllostachys) invasive bamboo is really a problem. I have a neighbor who planted it on the property line, and I am hoping our county looks into the situation soon as it has already cost us 3,000 dollars to keep it off of our property. I live in Florida, and I just got back from a trip to Georgia where I saw it growing wild on the side of the road. You are right, Caryn’s website if full of great information. The sellers of this bamboo are trying to discredit her. Do not be fooled!

  25. Cathy on May 30, 2013 at 11:10 am

    Believe me, there is NOTHING that can be done to get rid of running bamboo. My neighbor allowed it to grow uncontrollably for years and I asked over time that something be done – even at mutual expense. Last year over the spring/summmer season I nearly collapsed digging out the roots, which were now up to my foundation. Finally I sent a letter asking for compensation to have a root barrier installed and asked that he pay for it; otherwise there would be court action. I won the case and was reimbursed $3k for the barrier. However,that’s not the end because next year I’ll have to have the topsoil removed to get out all the rhizomes. Don’t think bamboo will go away if mowed, sprayed with chemicals, etc. NOTHING WORKS short of digging up ALL the roots. Good luck!

  26. Connie on May 30, 2013 at 12:19 pm

    Wow– $3,000! That’s a lot of money to have to spend to keep out running bamboo. Up until a couple years ago, I didn’t even know that there was a type of bamboo could grow in our area, and I didn’t dream that it could be so invasive. Thank you for spelling it out for us, Cathy.

  27. Theresa on June 10, 2013 at 1:00 pm

    First of all, NOTHING kills bamboo – you MUST dig up the roots and the rhizomes. Without long dialogue, my neighbor’s bamboo spread into my yard and I had considerable damage. After refusal by the neighbor to work something out, I had a bamboo barrier put down in my yard (cost $2900) and sued the neighbor in small claims court. I won. Of course, I then had to restore my side of the property. I lost friendship of a neighbor, but gained control of my property. As a side note, no one will buy your property with bamboo growing on it! Excellent article below from Phila. Inquirer 3 weeks ago. That about says it all.
    http://articles.philly.com/2013-05-27/news/39540147_1_bamboo-shoots-backyard-invasive-plant

  28. Kirsten Reitan on June 10, 2013 at 2:07 pm

    A really good example of a property that used to be nice with a smidgeon of bamboo but is now overrun sits on the corner of LeBrun and LeBrun Circle just one house away from the corner of LeBrun and Eggert Road in Eggertsville. The effect is one of jungle now. Check it out if you are near the VA hospital or traveling in Eggertsville.

  29. Carol Merritt on June 10, 2013 at 8:57 pm

    People who think running bamboo can be compared to dandelions or other weeds in their lawns are showing their lack of knowledge on this subject. We have been battling this plant for about 5 years. My husband injured his knee from the constant digging in an sttempt to keep the bamboo rhizomes off our property. He has had 2 surgeries and now walks with a permanent limp. We finally had a concrete barrier installed near the property line at a cost of 3,000 dollars. We have lost all the trees, landscaping, and the irrigation system on that side of our property. Running bamboo will destroy your foundation, concrete walks, driveway, pipes, watering system, landscaping, septic leach field, fences, and your pool. Once it is established on your property it will take a back hoe to remove it, and any peices left in the soil can then resprout and the nightmare begins all over again. Weed killers may harm an established plant but they usually will not kill it. The plant spread and does it’s damage underground where you cannot see it. It stores energy in the underground rhizomes so if you cut it down it simply grows back again. The underground part of it needs to be completely removed. You can continually mow, but if it leafs out in between mowings it stores more energy and the process begins again. It will take about 3 years of constant mowing before the energy is spent. The U.S.D.A. states that one running bamboo plant can spread 9.3 miles in its lifetime. Our neighbor planted 5 of them on the property line on 1/3 of an acre. This plant needs to be contained when it is planted and even then it will probably escape in time as the containment materials break down.I have photos of it coming up through the siding on a house, under wooden decks, under concrete, thorough a concrete pool, and growing through the asphalt in the middle of a road. I don’t think this plant has any business being used for landscaping purposes on the average residential lot. We need laws!

  30. Beverly on June 18, 2013 at 5:30 pm

    Yes. We need laws! I am currently trying to have a bill introduced in Baltimore County, MD. I’ve been digging out rhizomes from my neighbor’s bamboo for 15 years. If you live in Baltimore County please call your county councilperson and tell them your bamboo nightmare. Ask them to support a bill to ban or require containment of running bamboo and make the people who allow bamboo to destroy their neighbor’s property financially responsible for the removal of it. You can contact me at banbamboonow@gmail.com.

  32. Jim on October 11, 2013 at 1:25 pm

    For those readers in the Buffalo New York area it is useful to know the behaviour of the plants in your climate zone. Most of the spreading bamboos are grown in zones 7-9 and can be quite invasive. They do not generally invade foundations, sidewalks, concrete structures nor pipes as has been previously stated. They will breach fence lines and require barriers 3-4 inches above ground and extending up to 18 inches below grade of a thickness of 30-60 mil plastic.
    A relatively few spreading species are grown in temperate zones (3-6) and they tend to grow much more slowly, spread much less rapidly, and grow to only 30-50% the height of their southern brethren. They can be controlled by a 6-8 inch trench around the desired perimeter which allows you to visualize rhizomes that are spreading beyond the desired zone of containment, and they also can be mowed like grass to control their spread.
    The owners of the property on LeBrun have done nothing to control any of the bamboo growing there now for over 6 years, since the October Storm of 2006. This highlights the relatively indolent nature of the plants in Zone 5. Bamboo has the highly desireable property of simply bending over in snow/ice/wind and does not break nor represent any threat to people or property from heavy falling limbs or uprooted mass as with trees.
    When properly tended and maintained, bamboo is a beautiful addition to many gardens and should not be demonized by people with little or no experience in its cultivation in Buffalo New York. Reasonable care properly locating and caring for it will assure that it is MUCH less of a threat to you or your neighbors than most of the beautiful trees that we admire so much in the northeast.

  33. Michelle Schmitt on October 11, 2013 at 5:22 pm

    Thank you Jim! A voice of reason is a very pleasant sound.

  34. Connie on October 13, 2013 at 5:15 am

    Jim, thanks for that detailed explanation for dealing with spreading bamboos in Western New York.

  35. Tony C on April 26, 2014 at 6:28 pm

    Is there a garden center in western New York selling the “clump” bamboo?

  36. Connie on April 27, 2014 at 7:32 am

    I don’t know which garden centers, if any, sell clump bamboo, but you can contact them to find out. See a list of gardening businesses in our Gardening Directory and see more information under Garden Resources. You can also click on one of the ads on the right side of the Buffalo-NiagaraGardening.com website to go to those businesses’ websites and get their contact information. I hope that helps.

  37. Marva on August 7, 2014 at 7:31 am

    I planted bamboo over 10 years ago on both sides. No warning from the garden centre regarding it’s invasive nature. Hands up it’s my fault. I accept total responsibility. A decade later, it’s invaded our neighbours on both sides. We bought a mattock. And are digging up massive rhizomes. I’m not demonising bamboo. It’s a lovely plant. But my bamboo was out of control and affecting our neighbours gardens. Eradicating bamboo is backbreaking work!!! My neighbour to my right has a little patch of soil that the bamboo has grown through. She told me she wants to plant flowers next year. Really! I told her she may have to wait several years for that: she’s not prepared to wait. She has no idea that in this case; the bamboo is the master for now. My husband and I went over to her garden, dug up the roots,lay down clear plastic, put bricks on the soil to hold it down six weeks ago. We’re using the method of solarisation: bamboo needs air and water to thrive. We’ve deprived it of both. When the sun is shining this will effectively kill the bamboo root system. But you must change the plastic every 4-6 weeks so that the plastic doesn’t disintegrate into the soil. Laying down fresh plastic each time you repeat this process. Last week I went over to her garden to lay down fresh plastic. She was standing over me showing me the roots alluding to the fact that. “You have to dig up the whole root.” I was bristling with rage! I wanted to hand her the mattock and say, “You dig!” My husband dug out the root system. She wants to teach me how to suck eggs!I went over to her garden in the first place to check how invasive the bamboo is. She said, “I didn’t want to complain.” We then proceeded to sort her garden out. She has a big fig tree that is hindering progress of getting this monster out! I might add, at no extra cost to her! At least we’re getting on with it! And yet she has ivy planted over 30 years invading the neighbouring garden directly behind us, and our brand new fence the builder and my husband erected!I haven’t seen her come over to my garden to fix her problem ivy! She claims she’s going to get rid of the ivy in the winter; it’s summer here in England now. But if she gets rid of the ivy now;the ivy is now the fence. So what? It’s hot and dry now:get somebody in to take the ivy down and erect a new fence! Nobody gardens in winter! I’d like to see her gardening in the freezing cold! She’s not going to do that. But of course it’s the age old saying, I’ll do it when I’m good and ready! My neighbours on the left, do no gardening at all. The neighbour wants me to do their gardening at £5.00 per hour. I told her, “£10.00.” The bamboo rhizomes have worked their way under their ill constructed patio. I’ve had to take the slabs away, my husband has dug up some of the rhizomes, with more digging yet to come. Whilst digging up rhizomes, the woman asked me about the fence. My husband said I should tell her, “If you paid me £10.00 I could use the money to buy a new fence!” My husband dug up our Phormium, the bamboo rhizomes are embedded in it. We threw it in the bin! Phormium number 2 will go the same route. It’s no use my neighbour to the right, moaning about our bamboo the next time, I go around to her, I’ll tell her to sort her ivy out! Lastly my neighbour on the left told me, “I’ve found a gardener.” I replied, “Good luck.”

  38. Connie on August 7, 2014 at 8:43 am

    Oh, dear. Such hard feelings. Maybe once the bamboo is eradicated, you can go back to having pleasant relationships with your neighbors. My readers can use this as a warning not to plant running bamboo. Best of luck to you.

  39. Marva on August 8, 2014 at 8:28 am

    Hi Connie relations between myself and the neighbours are harmonius. Everything I say is said with a smile. I might add that I didn’t appreciate my neighbour standing over me telling me that the bamboo shoots were still there! When I’m doing the best I can to help her. I could see the shoots perfectly. When I told her it would take 4 years before she could plant flowers. She replied, “I can’t wait that long. I want to plant flowers next year!” It’s OK my neighbour on the right wanting to plant flowers next year. In fact I applaud her optimism. She’s just uninformed about the nature of running bamboo. In some cases it can run metres away from the mother plant!

    One thing I should’ve mentioned – you need to saturate the soil before you attempt to pull up any rhizomes; it makes digging and pulling easier. On either side of the top of our garden are 2 metres of rhizomes and soil. I can’t get sentimental over these parts of the garden that are lost to digging, the bottom sides of our garden is bliss. I know that it will take years of digging up rhizomes, and my husband and I are prepared for that. My neighbour on the left still has the slabs up. We’re hoping to pull out more rhizomes and lay down plastic over the weekend. My neighbour on the right still has her plastic down; I’ll see her at the end of this month. And no doubt she’ll complain about the bamboo again!

    My neighbour on the left also has ivy planted by an old man long ago at the back of her garden invading our fence. We’ve got ivy coming at from both sides. But my neighbours aren’t in a rush to sort it out! Of course not. I’m getting rid of the invasive bamboo. What I don’t have time for is neighbours who do nothing about their invasive plants. As though they’ve got all the time in the world!

    Another thing my neighbour on the right has a fig tree where bamboo shoots are. She’s made the right noises about getting rid of it; but so far hasn’t moved a muscle on that. I used the lopper to cut off the taller shoots sprayed it with weedkiller,lay plastic down, and put a brick on it.

    My husband was out in the garden digging yesterday he told our neighbour on the right it will take 4 years to eradicate the bamboo/rhizomes. Her reply, “Oh dear.” My husband told her the same thing I told her! Is bad news better coming from a man?

  40. Connie on August 9, 2014 at 8:20 am

    Marva, thanks for the extra details on getting rid of bamboo. I’m sure readers will find that helpful.

  41. Theresa on August 9, 2014 at 5:35 pm

    First of all, NOTHING kills running bamboo – you MUST dig up the roots and the rhizomes then install a bamboo barrier. That’s the only thing that works and it’s backbreaking. Don’t waste your money on pesticides, salt, extension services, etc. You MUST dig up the roots and rhizomes. Without long dialogue, my neighbor’s bamboo spread into my yard and I had considerable damage. After refusal by the neighbor to work something out, I had the bamboo barrier put down between our yards (cost $2900) and sued in small claims court. I won. I lost friendship of a neighbor, but gained control of my property. As a side note, no one will buy your property with bamboo growing on it! An EXCELLENT article below is from Philadelphia Inquirer and at this link: That about says it all.

  42. Marva on August 19, 2014 at 6:57 am

    This is something I never expected to see! Over the weekend my husband was digging up the bamboo,(it’s never-ending). And he came across very hard thick roots. He started hacking away at it with the mattock. Without much success. He did however manage to dig out large thick roots. In the past I’d planted a fern there and came across this hard root, but I never thought it was this. Turned out it’s neighbour on the right. Her fig tree roots have invaded our garden! Touche! My husband showed our neighbour the fig tree roots. And I said, “I’ll expect you to come over to our garden and dig it out.” No reply from the neighbour. She just laughed. Another invasive plant to put on your list of invasive plants; fig trees. Who would’ve thought it?

  43. Fred Robbins on August 29, 2014 at 1:41 pm

    “First of all, NOTHING kills running bamboo – you MUST dig up the roots”

    This is FALSE.

    All you need to do is CUT the ENTIRE PLANT DOWN to the GROUND.

    ALL OF IT.

    It will grow back ONCE. Let the new shoots grow just until they begin to LEAF OUT. Then cut it all down to the ground.

    BAMBOO CANNOT LIVE UNDERGROUND. With no LEAVES ABOVE GROUND to GATHER SUNLIGHT the roots and rizhomes underground DIE.

    I HOPE I HAVE MADE THIS CLEAR AND SET THE RECORD STRAIGHT FOR YOU.

    THANK YOU FOR YOUR TIME.

  44. Jim on August 29, 2014 at 2:11 pm

    Almost a year ago I posted a comment about bamboo on this site. I am assuming that most readers are in the western New York area and understand the effect of climate on plants.
    Until Fred posted his comment today, the postings have continued to repeat and inflame this “bamboo hysteria” that is TOTALLY unfounded for this climate zone.
    Bamboo requires the same diligence and responsibility that goes with any gardening endeavor whether it be trees, shrubs, or ivy. In this climate zone the Phyllostachys (running) species that are commonly available are QUITE INDOLENT as a running spreading plant. Fred is absolutely correct about eradicating it totally, although, in the south, it can require several years of such treatment before it gives up.
    Likewise, if you just want to control its spread, barriers or simple mowing as you would any grass (Bamboo is a grass!) will do the job.
    Furthermore, I will repeat, Bamboo will not damage property nor persons in any storm, unlike the many well cared for and not so well cared for trees that we readily enjoy in upstate New York.

  45. Jen on October 21, 2014 at 4:13 pm

    I have more than a million questions, but for starters: People say let the new shoots grow until the leaf out, then cut them down again. The stalks we are dealing with do not ‘leaf out’ until they are waaaay tall, and I do not want to have tall stalks in my yard again. Some seem to have leaves before they are above the ground. We cut down about 20 stalks (large, tall, thick, bamboo) last winter, just before spring. We poisoned each root with Roundup (Gly). Then little ‘bushes’ of bamboo with leaves started sprouting up everywhere. Now, we have dug out as much of our yard as we could with a backhoe and excavator. Some areas we just can’t get to, under sidewalks, old driveways, behind walls. And our yard is multilayered with slopes. Impossible. But we dug out a major portion. Now we are going to put in 80 mil barrier. However, we can’t barrier everywhere because of gas lines, trees, water lines, walls, slopes, etc. We did rebuild an old concrete wall that had held back the bamboo for 20+ years from one area of our yard, until this past summer, one rhizome found a crack and went down into a concrete block and proceeded to grow downward until it found the dirt that then led under our asphalt driveway. And a stalk came up through the asphalt. We believe we severed that rhizome. We rebuilt the wall and FILLED it with conrete this time as well. Do you think that rhizome will still grow and continue out the other side of our asphalt driveway? Or is that pretty much gone now? Also, they haven’t for 20+ years, but will the rhizomes grow under that wall at all?? So many questions while we are in the midst of this process. We cannot cut down all the bamboo stalks, because the remainder 300 or so stalks are on our neighbor’s property, which is uphill from us. He likes his bamboo. So we are just doing the best we can. My biggest concerns now are this wall and keeping bamboo from the part of our yard where we have kept it so far, until that one rhizome broke through the block – which we have now fixed. Any help?
