Thanks Janie! You are right, it is efficent! Pest control is much easier, weeding is easier and the results are terrific. After the first year, it becomes even easier. You do not have to till, add a little compost and put in your plants and then go back inside to grab a beer!   It replace the idea of "row" planting which is something that farmers need to do, not backyard gardeners. You would be surprised at how much you can grow in a smaller space!
