Reluctantly I used Round-Up (tfui!) on an small area where nasty

I want to put something else in there, but am not too experienced
with Round-Up.

How long should I wait, for safety's sake, before transplanting a
shrub in that area?

You can safely overplant immediately. But it might be better to wait
until the weeds are showing some distress before you disturb them, to
make sure the RU has made its way into the roots.

Sorry, my message was not clear. The gardener who dug out the stump
took the weeds out as well. I was worried about deeper roots, so
applied
the (tfui) Round-Up. Nothing is now showing on the surface, so that
is why I am confused about how long I need to wait while Round-Up
does its thing underground.

You are wasting your time as it will not do anything underground. Glyphoste
needs to be absorbed through the leaves of the plant to work, it may then be
transported to other parts and so kill the whole plant not just where it
touched. This is why you are instructed to apply it to plants when they are
growing vigorously for best results.
