Tree ID and pruning

[acone]

Hi,

Can someone ID this tree please. Pics were taken in spring about 4 years ago hence the tree is a bit bigger now.



The problem I have is that shoots seem to be coming up from the tree's roots during the summer and breaking out all over the front lawn. I've tried cutting and using general weed killer on the shoots (which doesn't seem to affect the tree) but they grow back. Parts of the tree roots are also visible above the lawn with leaves/shoots sprouting from them too, hence mowing is increasingly difficult. Why is this happening and is there any way to stop the shoots popping up?

Tree is approximately 8m tall, trunk is about 6-7m from the house, dripline about 2-3m from the house. The tree has been pruned back a few times over the years. Do I need to be concerned about its proximity to the house?

On pruning/cutting back in general. If a tree is kept pruned back will it affect how the roots grow? If a tree is already well grown (I have some in back garden which have never been pruned) and it is cut back hard, how would this affect the roots i.e. would the roots stay the same, continue to grow or possibly recede?

Finally how far can a tree be cut back without killing it, is there a rule of thumb or is it dependant on type of tree.

Sorry for so many questions but I know nothing about trees.

Thanks in advance.

I cannot identify the tree but you DO NOT use weed killer on fruit trees (or any trees).
I pull off any suckers as they appear, but this may help

It looks like an ornamental Cherry to me. There are many varieties.

It looks like one of the double Japanese types of flowering cherry, Shimidsu or similar. You could prune it back a third or so each year to flower buds. they do tend to send up suckers, but pull them off, not cut. It won't affect the roots, they'll keep on growing searching out nutrients. You could trench round the tree and root prune perhaps. Get some advice from a local nursery?

As has been said, it is one of the many varieties of ornamental cherries. These trees are grafted onto 'wild cherry' stock, and it is that root-stock that is now causing a problem in your lawn.

The tree looks mature enough for you to remove the offending roots. Simply dig-up the part of the root that is sprouting, leaving a good clean cut. Remove all roots that are on or very close to the surface.

If there are many offending roots, it may be a good idea to do a bit each year over two or three years to give the tree a chance to recover.

If you leave these, they will become more and more of a nuisance as the years pass and make mowing difficult.

This is best done in the autumn after the leaves have fallen.
