Tree safe broadleaf herbicide?

 Hi, I have a number of dandelions in my yard (PNW), too many to spot treat,
and I'm not going to rip out the yard and resod it.

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.

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

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?

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

Thanks,

Jon

OK to use.  Just don't spray it on the tree foliage.

Well, the Walnut could go.  =P

How large are the trees?


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


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


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.

Just don't spray on the leaves of trees and make sure to not spray on
windy day so don't get drift and no problems.

And, of course, they're also detrimental to almost any broadleaf plant
so keep away from shrubbery, perennials, etc., etc, etc, ...
