Removing leylandii, carefully Discussion in ' General Gardening Discussion ' started by hmallett , Apr 12, The previous owners of our house planted 2 leylandii horizontalis and a small leylandii-type tree in the front garden. I haven't been hugely keen on these since we moved in they were growing into the road!
The previous owners had obviously planted them to hide the covers, but now the covers have been pushed up and are at wonky angles, presumably due to the roots moving them. So we decided they had to go. So in a nutshell, how deep will the leylandii roots go, or do they spread out?
What's the best way to remove them bearing in mind that there are water pipes there? Use an axe on the easy bits and leave any difficult bits in situ? I'm preparing for this to take a full day or two, but my girlfriend wants me to do it all before haer parents turn up in a couple of hours! The leylandii were about 8 years old BTW. Thanks, H. Hi H, The dreaded leylandii roots strike again. Normally leylandii roots tend to spread rather than have a tap root that goes straight down.
However, roots tend to grow wherever they can get water and nutrients, so they could, in theory, have gone anywhere. For total and quick root removal you'd ideally want to get a stump grinder in, but that could be costly. The roots are fairly close to the surface and can fall victim to lawnmowers. The plant can also fall prey to other hardier root systems that are in competition for space and nutrients.
Two main diseases plague the Leyland cypress. Phytophthora rot is a disease that affects smaller roots and smaller trees. It causes yellowing of the foliage and tip die back. The disease is worse in areas with poor drainage and can only be diagnosed by a lab. The other disease is Annosus root rot.
It starts with a fungus that grows on plant stumps, primarily pine. The disease travels through the roots of the stump and is spread by touching other plants roots. The large roots of the newly infected tree die and eventually the tree will die. The symptoms start with yellowing of the roots and can progress to brown or reddish brown foliage. Clear possibility of undermining, then. And keeping them topped at six feet will be hard - what if the house - either!
And it'll push the fence over. And nowt will grow under it - and I wanted to plant stuff! Ditto the one at the bottom of the garden but that's not right next to a six bedroom house! A pox on the breed. Je Suis Charlie! Yes they aren't the best things to plant for hedges but they are short lived fast growing conifers. The roots will not grow under your BF's house and topple it. They aren't that strong.
I have an 8 foot Leylandii Hedge alongside my house and it is trimmed twice a year in a neat box shape. It is a brilliant screen against a north wind. I didn't plant it but I do ensure I manage it well. I don't no where you got the information from about spread of branches and roots but it is pure scaremongering it seems to me.
Now if these trees have been planted very close and your BF feels it has been done for the express purpose of causing the neighbours problems you can go to a website that can give you all the advice you need on this particular problem as there has been some extensive legislation over the last 20 years. Look on the forums there is reams and reams of stuff about this one problem. But don't panic, they will not rip up his foundations. Soil under houses is generally dessicated so no advantage to the tree to go there.
Can cause probs for drains but invariably due to blockage following entry via existing cracks or other defects. With much larger specimens, there is a potential for mechanical damage due to wind-rock.
Copper nails punched just below bark can have a deleterious effect, so I understand It is the owner of the trees that are the problem. Not the trees themselves. I would say if this can be resolved while they are mere twigs the better. How about suggesting an alternative less vigorous species.
Some folk plant out of ignorance and some out of malice. You would do we'll to find out which it is. They want a screen - on the other side of the garden, well so do we but we're going to top up the 5' fence to it's legal planning restricted free six feet and then add clumping bamboo to blot out a pirate climbing frame and plant firethorn to stop the kids from standing on things on their side and peering over or chatting incessantly when we're going about our business.
They are happy to climb on things they drag there to see over the fence but not to climb on the climbing pirate ship at all! But none of those measures will cause inconvenience, ire or otherwise, except bar perhaps a funny look when we explain that firethorn is well named for reasons obvious. And all a darned sight better looking than Leylandii! Blessed is he who expecteth nowt, for he won't be disappointed.
The previous owners of our house planted bamboo to the side of a very attractive and expensive summer house. When we moved in not only had it completed surrounded the summer house it had invaded our next door neighbours garden and, even more scary, was growing inside the summer house and had lifted off the roof!
It is mean, mean stuff. You know, according to Kew, they used it to torture prisoners of war. They would string them up over the top of emerging shoots and it would grow at a phenomenal rate per day and pearce the skin you can guess the rest.
Not that I think you might consider torturing your neighbours thus but you might well rue the day you planted it. Alternatively, if you are more concerned about the plant root damage, it may be worth consulting with a gardening expert or a tree surgeon before choosing to pull up the roots, especially if you are concerned of damage to your property.
