Jim, I have a number of the species of Hymenocallis, and I let them tell me what they want. About now, nightimes have gotten to 40 F, I move them into my greenhouse where the winter minimum is 50 F. I hold back on watering, but don't totally dry off. If the leaves stay green they get occasional water all winter long. If the leaves die back, they get no water except a small drink every 6 - 8 weeks to keep the pots from getting stone dry. When I let them get totally dried out, the plants were slow to recover in the spring, and didn't flower well. I call it springtime in late February or early March, and give them all a good drink, then again in late March, and by April they are all showing green again. No fertilizer in the winter, and various of 20-20-20, one of the "blossom boosters", and maybe an organic like seaweed or fish plus kelp throughout the growing season. All at half or third strength. Some of the liquid formulations for cactus feeding seem to work pretty well also.
