750 seed/gram For New Lawns, spread good clean topsoil to a depth of 15 cm (6”). Break up any clumps and rake level. For repairing old lawns, mow grass close to the soil surface. Rake vigorously to remove clippings and accumulated thatch. Add top soil to fill in any low spots then rake smooth. Grass seed can be applied in spring when the soil warms and again from mid August to late September. Note that cold soil can greatly extend the normal germination time. Sow grass seed at a rate of 500 g per 25 sq. m (1 lb per 250 sq. ft.) Apply twice at half rate over the area in a criss-cross pattern. Lightly rake the seeded area to just barely cover the seed with soil. Roll once with a roller at half capacity if the soil is light. Water with a fine spray for two or three weeks to keep the seedbed moist. Mow for the first time when seedlings reach 8 cm (3“) height.
