Curious to know if anyone has used this on their lawn? Is this dangerous to animals that forage? How long should I wait to let my hens back out or is there a "safer" weed killer that the DH should get? Thanks!
IMO, there are NO safe weed killers. You can do a home made concoction that has white vinegar and dish detergent as a base. There may be other ingredients as well. I have no idea how effective this stuff will be, but it will "burn" every leaf it touches. May take multiple applications, and it may take a toll on the soil. If you're looking for a "golf green" lawn. without any weeds, you can either give up that idea, or keep your chickens in their run at all times. I'm happy with just plain green, and consider the clover and dandelions to be a nice nutritional additive. Burdock, creeping charlie, and thistles are more of a nuisance, but I'd not spray them.
Welcome! Green is good, weed killers, not so much. Vinegar may kill some weeds as a spot- on application, but treating lawns with herbicides is a bad idea. Mary
