Mr. Walker built a new home on a two-acre lot. The house, drive, and walks contain 3,200 square feet. He has an area for plants in front of the house 5 feet wide and 62 feet long to which 4 inches of topsoil were added. In front of the other plants in the area, he set out annuals 8 inches apart. The annuals come in trays of 12 four-packs. He laid 150 feet by 110 feet of sod in the front lawn. The remainder of the lawn was seeded with 2.2 pounds of grass seed per 1,000 square feet, and he applied 4.5 pounds of nitrogen per 1,000 square feet using the lawn fertilizer 20-5-10 that comes in 50-pound bags.
