Please help! Weed taking over my yard!
I am desperately looking for some advice. We have a large yard, and last year a small patch of the attached weed appeared. As of now, at least a third of our yard is covered! I am hoping someone can let me know:
1 - What this is called
2 - How to best get rid of it, while complying with Ontario's pesticide-free laws
3 - Whether it would be best to just cut up a big chunk of my lawn and re-sod or try killing this and then re-seeding.
Many warm thanks to whoever can help!!!
