RE: Will glyphosate kill trees also?

Yes Round Up will kill trees if the application is strong enough.
Round Up works at different 'speeds'.  When the plants are vigorously
growing, you can see it begin to die in 24hours.  OTOH, I have sprayed
it on clover in November and December and did not see results for
several weeks/months.  Avoid periods when it will rain in 24 hours, if
you can(despite what the advertisements say).

Best regards from Decatur IL!

Subject: Will glyphosate kill trees also?

My wife and I have purchased a small (1/3 acre) home site in central
Illinois (Mattoon).  It has a few trees (Silver Maple, Osage Orange,
Common
Hackberry, Black Cherry and Butternut, most in an old fencerow) with
lawn
grasses throughout.  We won't be building for a few years but want to
get a
head start on changing from lawn grasses to all native shrubs and
grasses.

Questions:  First, will the glyphosate I am currently planning to use to
kill the lawn grasses under and around the trees (in preparation for
native
plantings) damage or kill the trees also?
            Second, I am assuming the glyphosate will be effective any
time
after the grass greens up.  How long after appllication does it take for
an
effective kill.

Thanks for your help with this.
