We had a largish tree-70ft within 20yards of the house, which was
throwing up suckers within 10ft of the house and at other parts of
the garden.
We cut it down in February this year and as you might expect
suckering is stronger than ever.
We can deal with these, they are obvious on the lawn but in a hedge
or amongst trees they can get to quite a large size before they are
noticed.
Is there any way of terminating their activity or is it going to be
a
year on year attrition?
The original stump is still in the ground.

I'm afraid most or all of the suckers will have to be treated as
separate trees; and, of course, the sooner the better from your point
of view.
