If there is dew on the ground or a chance of rain, wait for the grass to dry or the rain to pass.

well I was buying the roundup concentrate and mixing it double the amount it said to use and I only did it after 10am when the grass was completely dry and no rain that day or at least for several hours away. it did work great to kill stuff but 2 or 3 weeks later under the house there was new weeds sprouting everywhere and this is old dirt that's been there for 5 years so its not like I put new soil there that had weed seeds contained in it. every 2 or 3 weeks like clockwork, no matter what I have been spraying it with, I see a new crop of weeds sprouting again. now a quick respray kills it but im trying to eradicate them permanently and I think it should be possible to do it since this is a closed off section of ground completely surrounded by a 12" deep concrete chain wall foundation barrier on all sides and once it is cleared of all weeds and new weed growth it should stay that way permanently so that is my goal.

sounds like I should mix both for under the house where I want it to be a scorched earth nuclear waste zone then .

thanks for the warning about that, that's great info to know.

when I combine them I will premix the stuff in a separate water jug then pour it into the sprayer as I need it so any solids stay out of the sprayer
