I was very fortunate that did not lose any daylily plants planted outside. That includes the 165 double fans I received from Maryott's the first week of October. I planted the fans without dividing, mulched with dry leaves and pine needles. It took me three weeks to plant them all because by I am a working woman.
Of course, all 256 potted plants in the cool greenhouse look great. I divided most double fans, and these grew well and are growing another fan. The dormants went dormant for three months. For most of the time, the temperature was just 40°. I did not add any light.
During the next few weeks, I will start to move pots to a very sheltered outdoor location where I will cut back the foliage. This location is sheltered from wind and sun, and by Mother's Day, most should be ready to be planted in the ground.
Meanwhile, new fans will start arriving in less than two weeks, and these will be potted and will go in the greenhouse until early June. These will stay potted until next spring, and, yes, the will spend the winter in the cool greenhouse.
