There are so many ways to look at it. Is weeding defense of your crop, or herbal genocide? Have you considered which "weeds" might actually be edible? Is there a benefit to allowing portions of your garden to go fallow for a season and letting some weeds take over? Is there a better way to garden that is more in tune with the harmony of nature?
I'm good at asking questions. Not so good at providing answers.
I have the same problem, asking but not solving. I do know which ones are edible and which ones will take over the entire yard.
