Fertilization
Lawns need certain nutrients to survive and grow. These nutrients are found in the soil and surrounding environment and are used up by the grass plant. You will need to provide appropriate amounts of Nitrogen (N), Phosphorus (P) and Potassium (K) for optimum health. Do a soil test first to determine what your lawn needs. Timing can be critical, so follow the Yard Care Calendar closely.
Cultivation
A process that loosens or removes soil to allow better air and water movement. Core cultivation, or plugging, mechanically removes plugs of topsoil to provide oxygen, water, fertilizer, and organic matter to the grass roots for healthier growth.Also referred to as aeration and core cultivation.
Over-Seeding
The process of introducing new grass species to existing lawns by spreading the new seed over established areas that have been prepared for renovation.
Pre-Emergence Crabgrass Control
Control crabgrass and other annual weeds are best controlled before they germinate. Pre-emergent herbicides work best when they completely cover the lawn and are designed to remain in the soil to prevent weeds from germinating all season long.
Post-Emergence Broadleaf Control
To keep broadleaf weeds like dandelion in control, apply post-emergent herbicide in the fall when these weeds are just beginning to germinate. Make sure the product sticks to the leaf surface and doesn't get washed off right away.
