I have a customer that has an old broken water fall and pond in her back yard. She doesn't want it as a water feature anymore, but instead of removing it (thank God, its huge and all rock) she wasn't to turn it into a flower garden. please corect me if my thinking is wrong, but I was thinking. 1 puncture the liner in many places for drainage. 2 fill half way with some type of sand. 3 fill the rest with top soil. 4 fert and work it till sping, then begin planting. Think this will work? It would make a very nice formal flower garden. plust this has to be done all by hand. the back yard is more of a courtyard and you can just get a wheel barrow in it. The water fall is about 6ft tall. The pond is about2-3ft deep. 8ft wide and about 15-20 long. I haen't done exact measuments yet and I am still trying to figure out how to do this right.
