I saw some photos of daylilies in gardens in Florida in the Florida regional newsletter. They were grown in boxes that were completely raised off the ground by resting on bricks at the corners. In one garden it was bare soil under the boxes in the other garden it was either landscape fabric or plastic sheeting under the boxes.
Presumably the soil in the boxes would need to be nematode-free and the daylily plants would need to also be nematode free when first planted.
