Can I use diluted Roundup in evergreen carpet?

Round up will kill all plants its non selective

Hiya while I am not sure of what you mean exactly as an evergreen carpet I do know that if you want a plant or tree to survive don't use round up near it. Roundup is an extremely strong effective herbicide which will kill any living plant (more precisely the leaves) it touches. It also takes very little to kill a plant or tree.

Having said all that. I have had an issue with Lilly of the valley taking over as our property was vacant for 20 years the plants went unchecked all that time. I have tried just about everything else nothing even slowed them down. Of course they are a shade plant and growing under all of my trees that lined the property and are well over 100 years old.

• I got a large pop bottle and punctured 2 holes in the lid and added the Roundup mix into the bottle.
• I collected several sheets of plastic and newspaper. It is my understanding as long as the chemical doesn't touch the other plants or roots they should be ok.
• What you want to do is to apply the round up to the leaves ( no need to soak everything down) Just a few good drops to the leaves of the target plants should do the trick.
• Use the plastic or paper to protect the other plants you want to keep. Wait a week to ten days and you should see them begin to die. Protect all plants from accidental contact. since accidents occur what I did was immediately break or cut the infected leaf then flush the plant really well with water. This worked like a charm for me.
