We recently moved into a house in London, UK, that has the trees
pictured growing at the edge of the garden. On the side facing the
garden, the trees are covered with what I think (but I'm not certain)
are small dead branches. We'd quite like to remove them as they look
unsightly, but are unsure whether this is advisable or how to do it?

Can anyone confirm from the pictures what the apparent dead wood is
and
whether it can be removed (and if so, how) without causing harm to the
trees? The wood is quite dry to the touch. It seems to be fairly
tangled
and attached to the trees which I'm guessing makes trying to pull it
down (eg. with a rake) unfeasible.

Thanks

The photos look as if some kind of vine was growing on the trees and
was
then cut away at the bottom without removing the top growth. I see a
similar situation near my house where wisteria grew to the top of an
Italian cypress. The wisteria would have eventually killed the
cypress
but was cut last year near the ground. The dead vine is still up in
the
tree, well beyond anyone's reach other than with a crane.-

Yes, I'd agree with that. Could be a clematis or (gulp!) Russian vine.

Bit puzzled at the apparent lack of thicker branches, although those
may be underneath. Whatever, if it isn't dead it should be showing
signs of sprouting, which should then aid identification. It could be
cut down or pulled off as much as possible. It looks as though it's a
climber that doesn't stick onto its support (like hedera or
parthenocissus), but just scrambles through it. Even if it is stuck to

its support, cutting through the main trunk(s) will make sure the top
dies and can be removed. I can't see that its removal would harm the
supporting trees in any way.

It seems you're spot on. I managed to speak to the previous house owner
who confirmed that the stuff that looked to me like dead wood covering
most of the higher part of the trees is actually Russian vine - as far
as I can gather it's there deliberately because he liked it when it
bloomed. In fact in the last day or so I can see buds starting to appear
on the stuff.

He also pointed out to me where [he believes] the main stem is - picture
attached - an assembly that looks like curved branches coming out of the
ground, which I'd previous assumed was part of the tree as they were so
close to the trunk.

So it seems I have several trees - which I like because they make the
garden feel more private - all of which have their trunks covered with
English ivy and their branches mingled with Russian vine.

What I'm gathering from this thread is that both the vine is and the ivy
are likely to be threatening the trees so I probably need to remove them
both. I'm reluctant to use herbicide so near the trees so am inclined
to remove them by cutting them near the stems. (Though in the case of
the ivy, I don't yet know where it's growing from - I think I'll need to
remove a lot of foliage to find that out)

Out of interest, what would be the mechanism of the threat to the trees?
Is it competition with the roots in the soil or blocking out sunlight
from the trees, or both, or something else?

Although they may block out some light and weaken the tree, the main
problem is simply bulk/weight and wind resistance. A tree which may
otherwise withstand a strong wind because what it has grown above ground
is anchored by what its roots are doing below ground, may not tolerate
the additional resistance of what the climber has added. It could be
uprooted or the trunk could snap in a gale. It's not quite the same
thing, but some years ago I had a small frame about 8 feet high and 5
feet long supported by a couple of 2 x 4" timbers (much too thin!). A
Clematis montana had grown over it and after a particularly windy night
I found it on the ground, both 2 x 4s having been snapped off at ground
level.

If you can get to the stems of the climbers you can cut them off at
ground level. That will cause them to shoot from the ground. As they
come through, you can spray them with glyphosate, taking care to keep
the spray away from the green leaves of anything you want to keep
(including the trees). You will need to spray many times to kill these
climbers. Sometimes the root system is so extensive that to get enough
weedkiller in to do its job is nigh impossible. Another possibility is
to pull down as much as you can, but leaving it attached at the base,
and the branches on the ground. Let the leaves open on it, then place
the branches with the leaves on a large polythene sheet or tarpaulin, or
pack them in a large polythene bag (make sure there are no holes), then
spray that. Wrap up the polythene, or close the bag. After a couple of
days, open and spray again. Repeat until the leaves start to yellow.
Take care to avoid spray drift or walking in any weedkiller which drips
and then walking over the lawn.

Russian ivy is one of, if not the, fastest growing climber hardy in the
UK. Good luck!
