I live in the High Mojave Desert and all of my iris start losing their older
fans when the night temps drop from 55F down to the low 20f at night. Right
now I've been removing the old fans to let the new ones that are coming up
get the sunlight they need.

This is not necessarily true. My outdoor iris loose their old fans when
they're 1-3 years old depending on the harshness of the winter. Right now
some have new fans 6" tall while others are only a few inches and all
still have last years fans. I have seedlings in a cool greenhouse. And
while they ocassionally lose a leaf here and there, the fan never goes
dormant. We're not tropical here in SC. We've had nights into the mid 20's
this year with some days barely topping 50. But this is the weather iris
grow best in here.. They'll quit once the 80's & 90's settle in in May.

Yes Iris will lose their old fans in winter, even inside. My 200+ iris
are just now starting to grow new fans.

Does anyone know if potted irises loose their foliage in the winter? I
treated mines for iris borer and some are loosing their leaves. Thank
you!
