I live at 8300 foot elevation in Colorado.
My columbines always start out fine, then almost overnight, the leave start to disappear, the stems turn into sticks.
I cannot see any pests on them... it happens every year? I there something I can do? Is this common?

Black stems usually indicate a disease but I'm not sure which one it might be. You may be able to protect your columbines if you use a fungicide on them as they are first emerging. An alternative would be to dig the plants, work some compost into the soil and replant. Compost will help loosen the soil so it drains well which may keep the roots from developing diseases. Hope this helps!
