We are trying to decide where to plant a couple of fruit trees, on semi-
dwarfing root stock.

One location is by a West facing wall which has a soil pipe (and power and
water) running fairly close to it.

I will be searching the usual suspects, but is there any reliable guide to
how close to underground pipes and cables you can safely plant trees and
shrubs?

We may want to plant a Wisteria at the back of the house as well, with
similar constraints.

Cheers

How close? If close enough that a root could get between the wall
and it, then it's a potentially serious problem. It's amazing how
much force growing roots can exert.

Other than that, the type of soil makes a difference, because friable
soils move more easily, but semi-dwarfing rootstocks work by having
a feeble root system, so are not a major problem.

No. All simplistic rules are nonsense, anyway.

They are rather more vigorous, so I would be more cautious. But there
are a zillion planted in similar locations.

cables can flex - no issue. Pipes can flex a a bit, but not that much.

I would be happy planing near a well laid-in-shingle *continuous*
section of soil pipe - up to a foot or so.

Main problem is if the constant angle of drain gets disturbed and you
get pooling.. of sewage.

I would say with dwarf stock leave a meter or so, and if you have decent
access for a minidigger leave it. You might need it.

I had read at the time I planted one that their root systems are relatively
benign. I planted one about 3m from a drain about 5 years ago and it's gone
pretty mad - maybe 5m in 2 directions along walls. Any comments welcome . . .

Depends on the state of the pipe. If you suspect its old and might have some
cracks, hen avoid it. Electricity seems not to be an issue, but gas on the
other hand and potentially water, if still the old metal pipes can lead to
embarrassing issues, like a rose tree fracturing a gas pip with its roots,
since the pipe was more rust than metal at that point!
Took 20 years though. grin.

Soil pipe, water pipe and electricity cable all relatively recent.
Installed 2012 IIRC.

So will be PVC, and unlikely to suffer from root ingress unless mightily
disturbed,

Also probably quite deep - roots do not go deep, unless to seek a water
table that exists at a lower tevel

Oh - to answer my own question, quite aggressive it seems, from a web search.
I'll trim it back next spring.

If you're talking about trimming the top by pruning/lopping, that will
make it worse! Wisteria sends runners underground some way from the main
trunk. If you cut down or damage the main plant, it will respond by
boosting activity in those runners.

Type this into google ' sewers for adoption tree planting ' and the go to images.
It gives distances related to tree species.
