Agree 100%. Much cheaper, much easier, and probably even less lethal to people, animals, water supply, etc. Been using this same formula since neighbor shared it 12 years ago. The "recipe" specified "Dawn" detergent but doubt it would matter that much ? Not sure, I've stayed with the original. We've found it sure works better than whatever most of the commercial people spray..and not sure what is in their "formula !

Not something many people would bother to do, but a GREAT idea to keep down the amount of chemicals that go into our water supply for those who don't mind trying this.

This weed is called Spotted Spurge.
 

If you pull the weed, it will release seeds that you can deal with later. Do not use roundup unless you want to kill the surrounding grass and plants. Vinegar is iffy, less effective, and may kill surrounding plants as well. A targeted Herbicide is MSM. It will kill it, but you you must use it sparingly. Spray the plant once and you will see the spurge turn Purple. It may take a week for it to kill the plant entirely. Over use of the herbicide will kill surrounding grass. You can get MSM at store.doyourownpestcontrol.com. Use only as directed.

Weed?
 

When I read the title of your post I got a bit excited . . .

Weeds by any other name
 

For those plants, including grass that we have to buy, fertilize, and tend, we have nothing but love. Weeds come for free! And they are green, no? Trying to be "one with the weeds" here while still reflexively bending and pulling as I go....:bigbow:
