MochaJoe said:Since I'm new to starting daylily seeds, do the seedlings (growing inside under lights) have to be slowly hardened off like we have to do with tomato , pepper and other such plants here in SW Pennsylvania before we plant in May?
Not as much as you would think. My experience has been that unlike humans, plants don't 'tan', and any growth which developed in very low light conditions will become sun damaged to some degree and eventually be lost. You can't save much of it with acclimatization.
Daylilies are structurally much different than tender vegetables such as tomatoes and peppers. In the latter, the stems and growing points/buds can be damaged if exposed to full sun too abruptly, which could be catastrophic. With a daylily, the 'business end' of the plant is the underground crown, which will persist in spite of total elimination of the leaves.
