When can my children/pets use an area where Roundup has been
applied?
The moment Roundup has dried. It deactivates on contact with
soil, and is degraded by micro organisms leaving no residues in the
soil.
Can Roundup kill Japanese Knotweed?
Yes, but you will need to use Roundup Tree Stump & Root
Killer. It may take several applications – please read the label
for further advice.
When can I replant/reseed after treatment?
Immediately, if you want to. We recommend, however, leaving the
weeds at least 7 to 10 days to absorb the optimum amount of
Roundup.
