Best way to knock out 3 common weeds?
We own a half acre of woods behind our home. I went out today and started pulling weeds, but quickly realized this was neither feasible nor sustainable to do this forever. Does anyone have ideas on:
What type of weed killer would work for these weeds; nettles, thistles, mustard seed?
When is the best time to do so? I presume the spring but didn't know if there was value in a fall kill?
Two more pieces of information. We live in Minnesota with a hard freeze in the winter. My neighbors also have these weeds, so permanently knocking them out probably isn't likely (unless they also spray that is).
