Trees and Swa

i'd be sitting on my brains then.

You are correct , the root system does follow the pattern of the canopy . It's natures way of stopping them falling over.

A good rule of thumb but not always the case. For example poplars can apparently put out roots over 2 times their height. Silver Birches have a pretty small root system. We've got a large conifer (about 60ft high) just over the fence from us and there are 2" diameter roots surfacing in our lawn well outside the canopy area. I am not convinced cutting them would do any harm though.

If you want to go under the canopy I would avoid going within 5m of the trunk and carefully hand dig anything under the canopy and avoid cutting any significant roots.
Not that I really know what I am talking about either........

Close enough , different types have different root systems , and will expand beyond the canopy . If you see a massive branch there will be a massive root in the same direction.

To OP

Whats wrong with the original cable? If does need replacing why can't you follow the same route? Why 25mm?

May be a bit help if you are worried about the tree.:smile5:

tree roots will squash even the biggest armoured cables like a stick of gum , with time.
i'd route the cable on the opposite side of the garden to the tree even if it doubled the circuit length to be honest.

I'd leave in on the surface.

Sounds like the OP doesn't want any advice, nor is going to listen to any.

And why isn't this in the DIY section?

Thanks for the helpful and humorous replies. It does seem like there is a lack of information on this subject on the internet, or is it a case of arbourists keeping secrets so they can charge consultation fees?

To answer some questions, the existing cable is being replaced because it is too small, especially for bonding purposes, the existing route cannot be used because of other construction.

25mm because max demand is15kw, I know 16mm would comply, however we are out in the sticks, the supply runs underground for half a mile and there is already a large vd. The dno are not interested in improving it.

Surface is not an option as part of the run is lawn.

Why does Murdoch think I won't listen to advice? All I said was that I didn't want to pay for someone to tell me something I could research myself, hence the op. I think the concensus is to stay as far away from the tree as possible, but to be honest I am no wiser.

regards, Steve.
