Have you ever tried drowning your weeds?
I have sent them off with the garbage before, and felt bad that I was contributing to landfills. Past years I've mostly pulled weeds and thrown them on the blacktop to bake, before composting them. But I'm worried this actually dries the seeds and preps them to be spread far and wide by the wind. This year, I'm trying drowning my weeds, then adding them to the compost. Rumor has is that the "tea" the rotting weeds create is actually good fertilizer.
Does anyone have any experience with this they can share?
