The clump that almost died last winter- that one I had to wonder if it was due to excessive moisture from all the snow melting and the ground being frozen. Generally speaking I don't think that is the case- lilies, bearded irises, and various bulbs all prosper in the same beds. And the beds are situated on a hill, so the drainage is good most of the year. While the soil here is heavy, it is still very loamy. Water doesn't hang around long enough to puddle. I have one spot this is heavy clay where septic workers buried my topsoil and left clay subsoil exposed on top. It is full of rocks and terrible to work in, but is the spot where I had shastas last the longest- go figure...
