If there is a partial stand of grass on the lawn, even though the ground is not more than one-fourth covered, the best plan is to seed freely about twice a year and apply suitable fertilizers at frequent intervals. When the soil is composed partially of clay or has a clay subsoil, then Kentucky blue grass and red top should be suitable to use in equal quantities, by weight. If in shade add as much red fescue as either of the other grasses. If, however, the soil is largely sand, red top, red fescue, and, if obtainable, creeping bent or Rhode Island bent should be used in equal parts by weight. German bent seems to be the most available seed. Kentucky blue grass seems to do better in an alkaline soil which can be assured by applying lime or unleached wood ashes at the rate of 5 to 10 pounds per 100 square feet. If there is one-half a stand of grass it would be well to use seed at the rate of 50 pounds per acre or one pound for every 1,000 square feet of surface. If there is a less stand of grass, then more seed should be used. It would probably be well to seed before freezing weather is over in the spring and two months before freezing weather in the late summer or fall.
To stimulate as vigorous a growth of grass as possible a liberal application of compost, ground bone or one of the prepared stockyard manures, like sheep manure or prepared cow manure, should be broadcast on the surface. In the case of bone, this would be from 1 to 1 1/2 tons per acre, or from 5 to 7 1/2 pounds per hundred square feet, and of the prepared manures an even larger quantity. The application should be repeated late each fall. After the grass has well started, nitrate of soda could be used to advantage at the rate of 50 pounds per acre, or 2 ounces per 100 square feet when the ground is wet either from rain or from watering, or it may be washed in by watering immediately after application. It can be used as a stimulant from June to September at intervals of a month. Reseeding is desirable each spring and later summer or fall until a really good lawn is secured, when it might do to omit one seeding.
Clipping of the lawn with a lawn mower should begin as soon as it will cut the tops when set high and should be repeated at intervals of five days or a week. The clippings should be permitted to remain about the roots of the grass.
Watering should not be oftener than once in five days but should wet the soil to a depth of four inches when applied. Usually watering is too light and too frequent.
