PACASANDRA TURNED BROWN
Please send us photos of the pachysandra so we can see what you may be dealing with. How do you care for the groundcover?
The browning may be due to drought, too much moisture, or possibly volutella, a fungal disease. Stress, such as drought, makes pachysandra more susceptible to disease. Here's our website info on that: http://extension.umd.edu/hgic/volutella-dieback-pachysandra-groundcover
