I also am growing my daylilies in a natural spring area. It stays wet almost year-round. I was very nervous about planting them there but it was by far the best area for me to get to and for my farm plan. I was shocked when I weeded this week to see I only lost maybe 5 out of over 300. Most are thriving. I think the spring gives them good micronutrients. So don't despair its possible!
