My sunroom isn't air conditioned and almost all windows, which are open in summer months. Same temps outside as in sunroom. If they need more than the heat and humidity of a summer in Kansas, I wouldn't know how to provide that. But it's a good question. Thanks for continuing to help me figure it out.
I use a slow release fertilizer in the medium, plus a little basket with slow release in it that I pour over when watering, plus the water I use has KLite in it used for all plants each time watering, and once a month the fertilizer plus KelpPak plus the Quantum stuff Ray sells. More fertilizer than that?
I'm still thinking it has something to do with the bulbs getting too dried out in the winter, because the older ones are just desiccated more than I see with the ones others (like you Steve) show in the offseason.
