Hi Rich, Here's what I did last year, it requires a little planning but it's worth it. Instead of black plastic I purchased some landscaping fabric. It's a little more expensive than plastic but it's porus which allows water and air to reach the roots and inhibits evaporation which conserves on the watering. They say it's also reusable for three years which spreads the initial cost out a bit. Before laying the fabric down I planned out where I was going to plant my rows and buried soaker hoses. I belive the combination of the soaker hoses and landscaping fabric cut my water usage in half and the only weeds I pulled were directly around the bases of the plants where there was bare soil exposed. During the spring and summer I spread my grass clippings over the top of the fabric and in the fall when I pulled up the fabric I tilled in all the clippings. All in all it was the most maintenance free garden I've ever had. Watering was a snap, every three days I just turned the water on for an hour or so. No sprinklers to move or hoses laying around to trip on. Tim in Kalispell
