Reluctantly I used Round-Up (tfui!) on an small area where nasty weeds
had been obnoxiously growing around a stump I have just had removed.
I want to put something else in there, but am not too experienced with
How long should I wait, for safety's sake, before transplanting a
shrub in that area?
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
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.
I read the label of RoundUp concentrate some time ago, but I remember
that three days is sufficient time for the chemical remaining in the
soil to decompose. Its action depends on being taken up through foliage
and then translocating via sap into the roots. Any RoundUp applied to
the soil is wasted, but it is not persistent.

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.
