Wintering Hymenocallis

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 

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.
