Seeding, Fertilizing, and Aerating | Maryland Lawn Treatment

Early fall months are considered best for seeding; warm days and cool nights, along with light watering to start, are ideal conditions for seed germination. Since soil in this area is very acidic, a lime application to balance pH levels is also recommended. Balancing the pH of the soil will give grass seed a better chance to flourish.

For cool-season grasses, fertilization and aeration should also be done in late summer to early fall. Fertilizing helps a lawn recover from environmental stressors and encourages the natural thickening process of lawn grasses. A blend of dry and liquid fertilizers is considered best for feeding, but application timing varies by grass variety.

Aeration is the process of allowing air to move through the thatch layer of the lawn and into the soil. Core aeration removes plugs of soil and grass and puts them on top of the lawn. Spike aeration puts holes into the ground so the air and water can move into the soil profile. If grass seed is applied first, the spike aeration process will drive the seed into the ground. Both methods of aeration loosen the soil, allowing water to flow in and fresh air to oxygenate the soil. In addition, loose soil increases the efficacy of applied treatments such as fertilizer and pesticides.
