Volutella Dieback of Pachysandra

Asked April 2, 2020, 9:25 AM EDT

I've read your information sheet and it appears I have the volutella problem with my pachysandra as shown in the attached photos. The 30'x 25' bed has been fine for the last 25 years but now the problem is quite widespread in the bed with most plants affected. It probably started last year. The sheet says something about thinning with a lawn mower. Can you tell me more about doing this since it seems like an odd thing to do? Is there any hope for my bed? Do you recommend a fungicide?Thank you for your help.

That is a pretty advanced case of this disease on your planting bed, but it is worth a try to bring it back.
What you want to do is set your lawn mower on it's lowest setting, and mow the whole area. Then rake out and bag up the clippings and diseased portions of the plants. It looks like there is still green plant material and runners/roots and spring is the time of regrowth from these plant parts. Give it some time to mend.

We don't recommend fungicides as much as managing plants in ways that help air flow improvement for drying (thinning) or anything that helps keep leaves from holding water for long periods of time, which encourages disease.

Be sure to water the bed in times of drought.

If it doesn't work out, we would suggest a replacement planting of a mix of natives like ferns, comfrey, etc. More ideas on that here:
