I have read that glyphosate is deactivated when it comes into contact

one week and then safely plant shrubs in the same area of land a few
weeks later without there being any fears of the glyphosate which was
originally used?

Actually this is a slightly dodgy claim. It actually depends on the
soil. The glyphosate isn't destroyed on contact with the soil, which
is often how it gets repeated but it gets attached onto clay
particles. If you don't have clay particles because your soil is
primarily peat or sand then it can't happen. Also this can't be as
instantaneous as the marketing speak seems to suggest. If it were it
would constitute a risk of fire or explosion. It will take a while

If your soil contains clay,as admittedly most soils do, then you are
probably OK a week later.
