Red thread disease is a fungal infection found on lawns and other turfed areas. The Waterford playing fields have five cricket ovals, three turfed and two synthetic pitches. It is currently used mostly for association football matches, and is turfed with artificial turf. Within the grounds, overlooking the lake, is an unusual turfed amphitheatre. KGV's artificially turfed field is ESF's multipurpose sports facility. Also known as turfed stone leek, it may be cultivated commercially and for foliage. The Sharps were turfed out and the Sanatorium purchased from the Military. Both of the ends are turfed and unused as spectator areas. More than one turfed football pitch can be found inside the school campus. The entire green portion of the field is also turfed. WJU's soccer and women's lacrosse teams play on the turfed Bishop Schmitt Field.
