If I had to dig up daylilies to pot because they couldn't take heat and full sun, I think I would be turning a critical eye to those cultivars that needed that sort of treatment. I believe that daylilies have their comfort zone. What may be a thriving, robust plant in one zone, may fail miserably in another. If a daylily isn't happy in the zone it is growing in, it needs to live elsewhere. In my case, growing conditions are extreme. Full sun, constant high heat from March to November, no trees, no shade of any kind. If a daylily needs special treatment to grow and thrive here, then it has no place in my garden of 14 raised beds.
