Our sweet Woodruff started dying and we found these white ball like things at...
Your sweet woodruff is dying because it is infected with Southern blight, which tends to do damage when the temperatures rise. This fungus does not destroy the roots, so your sweet woodruff should survive and put out some foliage next year. The infested material from this year can harbor spores that will readily reinfest next year when the weather starts to get hot. You can remove the dead parts of the sweet woodruff, but do not compost it--discard it in the trash. Next spring, before it heats up you can spray a fungicide that lists Southern blight on the label.
