That leaves me to looking for an herbicide. *The only problem is that I have
a few trees (oak, maple, walnut), and I don't want to kill the trees.


Well, the Walnut could go. *=P

How large are the trees?



Looking at the labels, I see 2,4-D and Dicamba, both of which seem to be
toxic to trees.


If they're mature, it would take a pretty hefty dose.



My question is, for those of *you who have used these products around trees,
what has been your experience? *Have you been successful in keeping the
trees alive?


There'd be a lot of turf-care people out of work, who answered "no" to that
last question.



Also, is there perhaps a different formulation which might be less toxic to
the trees?


The rate given on the bag, when applied as directed, should be safe for
anything larger than a very small sapling.

Agree. With all the weed-n-feed put down, much of it unwarranted,
there would be a lot of dead trees around if they were that sensitive
to it.

But I don't see why you can't spot treat with a tank sprayer. That
minimizes the amount of herbicide and delivers the maximum amount
where it's needed, on the weed.
