Mini French Drain for raised garden?
I am building up my herb garden with retaining wall blocks. It's sort of triangular shaped measuring 8 ft x 6 ft x 10 ft. It will ultimately be about 2 feet deep with soil.
I bought 1" pvc pipe to make my own French drain. Will a pipe this size make any difference in drainage or functionality? (I know most of these drains are much larger in diameter) I am trying to prevent the breakdown of the walls over the years - we get some pretty heavy rains in the spring and summer in Denver, and I'd hate to see my pretty new herb garden flooded.
It's going to mean some extra work for me, but I want to do this project right as I have already invested many hours and too much money! On the other hand, if this small of a pipe won't make any difference to the structure, then why bother? Or, if this size of retaining wall is too small to warrant this type of drain system? The soil underneath is clay.
Thanks for your input.
