发帖数: 4965 | 1 I am going to apply roundup to my vege fields next year before planting my
veges.
the problem is when should I apply it? roundup breaks down in 10 days. if I
apply in early spring, the weeds have not come out yet, so they can't be
killed; if I apply after the weeds come out, then wait 2 weeks for the
roundup to disappear, then I lose 2 weeks of time, and may miss the proper
time to plant my seeds. | g***e
