Q: I need some other choices of St. Augustinegrass for a more shaded site.
A: Shade tolerant lawn grass needs about 4 hours of sunlight to perform properly. If you do not feel your site has sufficient sunlight consider some alternative ground covers such as Asiatic jasmine, mondo grass, liriope or Aztec grass. If you wish to try one of the more shade tolerant St. Augustinegrass varieties, then consider using ‘Delmar’ or ‘Seville’. ‘Delmar’ is considered a dwarf variety and should be mowed at a height of 1.5 to 2.5 inches. ‘Seville’ is also a dwarf variety which has finer leaf blades, grows a little taller than ‘Delmar’ and therefore it should be mowed at 2 to 2.5 inches in height. ‘Seville’ is not as cold tolerant and with the results of our last few winters it might not be the best choice here except along the coastal areas. Both have the same disease and insect issues as other St. Augustinegrasses especially if over- watered and/or over-fertilized with high nitrogen. Attached is a complete publication from the University of Florida regarding care, maintenance and selection of St. Augustinegrass. http://edis.ifas.ufl.edu/pdffiles/LH/LH01000.pdf
