I find Roundup takes 1 - 2 weeks to completely kill the plants it's
going to kill. The ones it won't kill take much longer. :-)
A second application is required for some weeds. The label tells you
The local gardening expert on the radio tells people that "he can't
recommend it", but Roundup can be mixed stronger than instructed. I
can't recommend it, either.
I don't know why he says he can't recommend it. Right on the label
for the concentrate it has a wide range of concentrations you can mix
it to, from 1% to at least 6%, maybe even 10%, not sure since I don't
have one here in front of me. The recommended concentration depends
on what the target plant is
Which does bring up another factor. At higher concentrations it will
tend to not only kill more hardy plants, but also achieve kill
somewhat faster. At cold temps, I use a higher concentration.
