cut those trees, any risk of heave?

I don't know what kind of tree it is, The tree just next to the house, it looks ok to cut, my concern is heave, If I leave it it might cause subsidence? next to this tree about 8 meters there are another two bigger trees. if I cut the tree in this picture the extra water might be taken by other plants?
Thanks

You don't get problems with heave on sandy soil because it is fairly free-draining anyway. Heave is an issue on heavy clay which shrinks as it dries out, so when you remove a large tree, the soil absorbs water rapidly over a short period of time, and expands. That is heave.

That thing you want to cut back is far too small to cause heave by its removal or pruning.

Thanks, I got two large white beam trees which are just next the house about 3 metres, so far no problem, by some reason I cannot cut it this year, if this summer is too dry, can I just girdling it cut deeply to the bark to stop it transfer water? And next year or two years later I will cut it off.

@imiami you seem to be very, very anxious about this, I really do think it’s wel worth getting a tree surgeon round to look at all your trees and explain what your options are and how it all works. You don’t have to have them do the work but I think it’d really help you

I don't understand why you want to remove these trees. They won't damage the house or take too much water. Trees 3m from the house are great and will give shade without affecting the foundations at all.

Leave them all alone.

Pruning the cherry-looking thing OP started the thread about could give a great effect. No actually need to prune though.

TBH the thread doesn’t seem to actually be about gardening at all, but about OPs unfounded anxiety about the foundations of her house

Whitebeams are not large forest trees, and they are not a known species for causing subsidence or heave.

You do not need to remove them.

Leave them alone. Trees are good for the planet, and we need all the trees we can get if we are ever going to do anything about reversing climate change.

I love trees, but
I checked: the recommended safe distance from buildings, white beam is 11metre,

As there are another two big trees not far away.
And all of those trees are too close to the house.

Too close for what?

Not all trees are invasive or a problem, some trees will be killed by pollarding, others thrive on it. They can also provide shade from direct sun and baffle road noise (if either apply). A healthy silver birch can be lovely by a house but I wouldn't want an ash tree or willow too close.

Get a tree surgeon to look at them, confirm what they actually are and recommend proper management. Don't rely on guesswork or what we can guess from the pictures. That bark looks birch like to me but the tree shape doesn't.

But you don't know what the tree is - is it confirmed as white beam? Was that 11m recommendation from a tree officer or tree surgeon's recommendation or a building company?

IME very few builders or surveyors really understand the differences in trees and how to manage them effectively - I've met the odd structural engineer who has good knowledge but they commonly have a tree and soil specialist in their black book for advice. This is why I'd always ask a tree and soil specialist before fixing on a management plan because the wrong management plan can cause more problems than it solves.

What exactly is the point of this thread?!

OP, what exactly are your concerns? Initially you came across as someone with no knowledge at all, wanting to know what to do with one little tree, and now you're concerned about some other trees.

Perhaps a diagram and more photos would help...

Thanks,White beam is not in this picture, there are another two big white beam about minimal 30 years old.
