Kelli, you could collect the water from the gutters into barrels and use it for watering and it would still be going into the soil. For us that would mean the water going to the plants I want and not just weeds. But then again, to keep the water from the weeds I would need to have water collectors all over the yard, lol. We just had a worker here for several days pulling weeds and now have a mountain of them off to the side! What to do with them other than have to pay to go to them dump? I am loving the nakedness of the dirt right now.
