The best time to seed to put in lawn is preferably in September after the months of hottest weather and when there is a good moisture condition. May plantings usually suffer from competition with crab grass and other summer weeds, heat and inadequate moisture? Usually it is best to make a temporary lawn of rye grass where seeding is necessary in late May or during the summer and then turn this cover under for permanent seeding in early fall.

Process to sow the seed

Grass seed for lawn is relatively small and must not be planted deeply. Cover larger seeds such as rye grass and chewing fescue with soil to provide enough contact with the moist soil for germination and growth. Small seeds, like the bent grasses need only partial covering in moist seasons. Heavier seeding will not make up for poor-quality seed or a poorly prepared seedbed as it merely causes an excess of competition between seedlings.
If possible, use a mechanical spreader. Whether by hand or a spreader, sow by dividing the seed and spreading part in one direction. This insures even coverage and lessens the chance of missed spots or windrows. Collect the seed lightly or drag a flexible steel doormat over the area. Then roll lightly to firm the seed into the soil.

How to grow best lawn seeds

Natural rainfall is best for new seeding, but if the weather is dry it is necessary to water for prompt germination. Do watering in the morning, with a fine mist like spray to avoid pooling or crust formation. Once the seed has started to sprout, the moisture supply must be constant or the plants may die. For level places use a sprinkler and get the soil wet at least 5 inches with each watering. Don't keep watering until the soil is waterlogged and too compact. For slopes use a canvas hose or wrap the hose in porous canvas so that the water will ooze out slowly in big drops and go off into the soil quickly. Seed mixtures in new plantings develop unevenly. Where the subsoil is thick or clayey, it is essential for the well being of the lawn that subsoil drainage be installed.
