I want to pour concrete in a mow-curbed border in our back yard. The yard is hugh and too much for me to care for so I want keep some plants/flowers in areas and concrete in between 5-6 feet and add small rocks into that concrete for decoration. I also would like to pour this concrete at a slight upward angle/grade if possible. My concerns are this: what do I do about the sprinklers we need for the plants that are kept? how do you pour concrete at an angle/grade on dirt? what do I do about possible lighting? ( I was thinking of going solar), and I would be pouring a against a wood fence that has space between each board. Also I would leave little "cut-outs" in the concrete for future planting of flowers. Any advice you can give would be great. thanks.
