withering leaves on vinca minor

Posted by sleonardtx 7 (My Page) on

Each spring, my vinca grows vigourously for about a month and then begins to die back. The symptoms begin by a withering of individual leaves, followed by the stem and finally the entire plant. The adjacent plant may or may not be affected. I lose up to 50% of my foliage each year.
Does anyone know a cause or a treatment for this?

Very hard to tell from the picture, but looks like it MIGHT be root/stem rot of vinca. Google the subject and go to "images" for comparison. A good article is attached. I have seen a lot of this malady around my area in the last couple of very wet years, especially in clay soils.

I've seen several diseases on Vinca minor. Some are very similar in their symptoms. I'd recommend taking a sample by your local Extension office for proper diagnosis.
