How Long Till Roundup Works?

 

    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.

 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?

Thanks!

Follow the directions.


No! It might require other measures for eradication.

 
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.





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.

What about generic Roundup?

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
how.

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.
