frankrichards16 said:I use 2-4D weed killer. It will not kill daylilies (monocots), but it does a good job on thistle (broad leaf weed). If you use a concentrate, make sure you add the recommended amount of water. An incorrect "heavy" mixture can kill everything (kind of like Roundup).

Of course, 2-4D will not kill grass.

It will kill St. Augustine grass!

I was trying to kill some grass to do a flower bed and found out by accident. Thanks for telling me for sure that it will not harm the daylilies. Should I use the weed-n-feed or buy the liquid and mix it up as directed?
