April 15; Fertilize with fast release 15-5-10 fertilizer (1 pound N per 1000 sq. ft.) after second mowing (if lawn is very shady, decrease fertilizer amount by one half; or wait until fall to fertilize); mow at 5 to 7 day intervals at a height of 3? (use a mulching blade, and drop clippings); begin watering 1 inch per week, April through June.
