Hi, my name is David and I am in Eugene. I have a flower and veggie garden on my 5 acre farm with my wife and 4 labs. My pony has a pasture to himself. Lately there is an infestation in this pasture with a daisy-like weed. Can anyone identify it? Better yet, how do I get rid of it? It is crowding out the grass and it is getting worse. I recently found this site and I love it. I am still learning about gardening and I feel I have some knowledge I can share as well as learning from all of you. Thanks!
