i took these out of the garden in the house i bought and was surprised how eassy it was the roots were not deep and not large. the plants were about 8 - 10 ft tall.

couldn;t you dig down and concrete you boundary so the roots cant grow into your land?

This plant is a lot taller. I can see the roots when the digger was digging the trenches for the foundation.

I considered concreting the boundary, but my builder thought it a non starter.

Get rid of the arboreal abomination. If your neighbour just lets it have it's head it can reach 35 m and 8 m width . bloke next door to me has a line of them adjacent to his end fence and they block the sun out of his garden for half the day.

We were very lucky when we rented a HA house and found a row of leylandi across the back of 10 houses because we complained (the other neighbours had resigned themselves to the fact they had to live with them) to the Council and they were removed under the Anti-social act!! Poor things were issued an ASBO!

There is a calculation which can be used to work out if the tree is indeed being anti-social. I am sure a quick google should tell you.

However, I would rather take the tea, chat and meeting half way on the cost.

A brief update on this.

When the building inspector came out, the builders asked him to clarify exactly what his original concern was (expressed as a 'manageable height' originally).

His response was that we had 2 options :-
a) the connifer is removed completely
b) we have a concrete trench built to 2.2m depth

Option b) is going to cost us way more than removal of the connifer tree (I had a tree surgeon come and give me a quote).

I have to go back and speak with our neighbours and ideally push for a) and then we can fund a better replacement.

What annoys me is the change in tone from the building inspector. I wish he had expressed the preference for removal or digging a trench when he first expressed the concern, and when the digger was here! It would have made life a lot easier ! :mad:

If the tree is over half its mature height - which for a Leylandi would be 10m - then according to the NHBC even if you remove the tree it will require the same depth of foundation as if the tree remained.
If the tree is less than half height - so less than 10m high - then you can calculate the tree depths using the tables in NHBC chapter 4.2 based on actual tree height. But even if you completely remove the tree at less than half height it will still require the foundations to be deeper than a normal trench.
BUt all this is based on it being a shrinkable clay - don't suppose you've had your soil tested?

Thanks for the reply

No we haven't had the soil tested. It is clay based you are right.

I will check the exact height of the tree.

how did you get on with this - we are having problems at the minute too - we may have to go down over 3 metres for the foundations which will cost thousands!

thanks for your reply hun - will let you know we get on x

The only way to approach a Leylandii is with a chain saw in your hand.
