Will my dead but sprouting Acer recover?

Hi all. My 10+ year old Acer blood good has been in a border for 5+ years after starting life in a pot.
This year (after not a particularly hard winter) it failed to sprout new leaves.
Some of the upper branches have black tips (it's 10+ foot tall) and no signs of life from the dead twigs.
Then in early May it has started sprouting from the trunk, about 2 foot above ground level.
Will this go on to re-grow and recover? Should I cut it off above the new shoots?
Have looked online and it mentions the shock of a plant trying to have one last go at survival, but doesn't say the likely outcome or whether to chop off above the new growth.
Any advice/experience of this would be great.
Thanks, Michael

 

If the upper part of the tree is dead, but lower down it's still alive, it will sprout from there.
If you leave it it will grow like a bush rather than a tree.
I have one. It doesn't have the graceful habit of a tree, but it's a decent multi-stemmed shrub.
You could leave it over summer and see if anything happens higher up, then prune off the dead parts in winter.

To find out where it's dead and alive, use a fingernail to gently scrape the skin from on the trunk. If you can see some green underneath it's still alive there.
When you reach a point where there's no green under the skin, then everything above is dead and can be pruned out.

When you prune out any branches, take a look at the cut end - if you can see black rings, then that's a sign of a virus that has caused the damage.

PS - any serious pruning should be done in the dead of winter as acers do have a habit of bleeding a lot of sap.

 

Many thanks Pete8, really appreciate your reply!
Fully suspect it's dead in the entire top half and we'll end up chopping it off above the new shoots in the winter and seeing how it responds next spring.
Fingers crossed!

I wonder if it's got damaged where the trunk splits into two. Y-shaped branch points like that can tend to be weak points.
