Hi! I have a Dahlia bed that faces east. All have come up big and are blooming,but one of them has begun suffering some kind of wilt. It effects a complete stalk at a time and is consuming the entire plant. None of the others have it. Help? Will it spread? Thanks Mike.

Dahlia can suffer from several diseases.
Thank you for the images, though despite these I'm not able to determine what is causing the die off.
