I bought some Roundup weed killer yesterday. I sprayed a part of the
fence line. How many days does it take for it to kill the weeds? I am
hoping Roundup would first kill the weeds, then I would take a weed-eater to
them in a week or two after Roundup does its job.



You should see signs of wilting in 24 to 48 hours, then they should be
dead in about a week. It's highly dependent on temps. Those times
are for70 to 80. If it's 45 deg, it can take much longer and isn't as
effective.





What about generic Roundup?



Follow the directions.



Also, I bought some Roundup Poison Ivy killer and sprayed some Ivy that is
growing on a tree. Will that stuff actually kill the Poison Ivy for the
summer?



It depends on how large the plant is. For larger vines, it's most
effective to cut the vine, then treat the leaves on the lower part.
It may require a couple applications.






No! It might require other measures for eradication.
