Frilly, the area of the discharge we are not able to grow trees, or build, on by law. Palms are an exception for some reason. I am on a low slanting hill. Recently, as I get rid of the lawn I bring in treated soil (so as not to become weed city) and level it. I am thinking of redoing the first clay areas I planted years ago using the method you mention. The daylilies seem to do well in the clay - at least in flowering - but the clumps took a long time to look decent. In the new soil I brought in, the fans take off like rockets.
When you did your water features, were you successful in bringing in the frogs?
