AlthePal...I'm in central Oregon @4500' my 30 varieties bought from Schreiners, have struggled in the fine volcanic dust for 3 years. Voles and moles take over the beds and bury the corms 3-4"deep...so I'm kinda at wits end. Last year I replanted the strongest plants into 5 gallon pots with new potting soil, left out all winter in -15 f weather. Finally got a good bloom this spring. Pots were frozen solid for 4 months.
Am I doing anything right? Will I have to repot every year? This fall I filled 30 pots, 3 plants each. 10 go into a south facing greenhouse, unwatered, 10 go into a bed 3"deep and 10 into a garage kept at 50 deg. I'll let you know how I did.
