Hello there,
Our columbine leaves have been turning a yellow/brown color. We have planted them in the same location before and have never ran into this problem. They are also planted at different locations throughout our garden and the leaves are all experiencing the same thing. We water them every other day (minus the weekends). The leaves don't have any white dust on them.
Any suggests?

The best growing conditions for columbine are well-drained
soil with high organic matter; full sun to part shade; and ample and consistent moisture. Foliage will scorch easily in heat
and dryness and can be cut to ground when no longer appears attractive. This often occurs by mid-summer in Denver. Furthermore, many
columbines are short-lived, especially if drainage is poor, typically 3 years or less.
The conditions for our columbines have been consistent for years. What we are noticing though is that we have them planted in several different areas in our garden with different soil and different climate conditions and all of columbines seem to be reacting the same (as in their leaves are the colors of the attached pictures). Do you think it might be a disease or fungus...
If you are providing too much irrigation, root rot can occur. The most common foliar disease of columbine is powdery mildew, which has whitish covering over the foliage, which I do not see in the photos. Remove and dispose of all dead foliage.
