If the area has experienced an excessive cold period, then this can be normal to an extent. If your area does not receive cold, then it could be a fungal infection.
It wouldn't hurt to apply some dolomitic lime and wettable sulfur, regardless of where you live. This will condition the soil, and kill off any potential pathogens.
