Gardening and Horticulture - Questions On Using "Roundup" For Weeds

Hello:

Am considering using the ROUNDUP product to control some weeds in my lawn.

As there are some very nice ornamentals and evergreens also, I am a bit worried about the Roundup migrating thru the soil and being picked up by the root systems of the "good stuff."

Have been told that it only works via what is applied to the green foliage, and is not picked up by "any" root systems.

Should I be concerned ?

Think it's (totally) safe for my use, even if some overspray gets into the ground ?

Any thoughts on this would be most appreciated.

Thanks,
Bob (is this the most appropriate forum for this question ?)

Bob -

I only use Roundup in an area where I want everything to go - no matter how careful I am, the overspray always seems to get on something I don't want killed. - mostly, I use weed killers meant only to kill weeds, and not the lawn. Your local nursery or garden center has a good selection.

Here's some instructions from Roundup's website - they do state that it does not go into the soil, as you said in your post.
How to Use
Adjust nozzle to a coarse spray. Spray the weeds you want to kill until thoroughly wet. When spot-treating weeds in a flower or vegetable garden, shield desirable plants from drift with a piece of cardboard or plastic. If desirable plant is accidentally sprayed, rinse off immediately with water. Always read and follow label directions.

Do not use Round-up on the lawn. Yes, you will kill more than the weeds. Best option is something like Weed-B-Gone which does not kill grass but will kill most lawn weeds.

Round-up works by being absorbed by the leaves, not the roots. You can kill the lawn today and sow new seed in a couple days.
The evergreens are afe, even if the get overspray. Woody plants are very hard to kill with round-up.

You don't have to soak the leaves with round-up. Most people overdo the spray which does nothing more than waste the product. Some weeds may be hard to kill and will need a repeat application in a week or two.

Unless you want to kill out everything growing in affected areas of lawn, then do not use Roundup. A broadleaf herbicide for weeds will not harm grass. Avoid spraying when it's breezy as you want the herbicide to land on the weeds.
