dead lawn

Asked March 29, 2018, 9:45 AM EDT

A large Part of my lawn will grow nothing. I had pachysandra, hostas, and other shady plants for 40 years. My pachysandra is still on a small part, but is dying. Can I use copper sulphate in case it's a fungus? I've contacted 2 soil labs but this is not their test. Thank you for your help.

We do not recommend a fungicide unless you know what you are spraying for.
Pachysandra can be susceptible to a fungal disease called volutella. This is hard to control in wet weather. Take a look at our website for photos to see if this is what you are referring to. Remove/trim back and thin plants/vines with severe symptoms. Removal of fallen debris and clean up of old leaves etc. will also help reduce the amount of moisture trapped and will promote faster drying of the planting bed.
Fungicides protect new foliage only and are not curatives. http://extension.umd.edu/hgic/volutella-dieback-pachysandra-groundcover

If you have not tested the soil in this area for several years it would be a good idea. Results will give pH and nutrient deficiencies but will not tell you why the plants are declining. http://extension.umd.edu/hgic/soils/soil-testing

Please send us photos of the site and affected plants so we can see what you are dealing with.
