• Lawn Roller: A tool used to press seeds or sod firmly into the soil.
• Lime: A soil amendment that raises soil pH and reduces acidity.

• Mulch: A material spread over soil to retain moisture, regulate temperature, and reduce weed growth.
• Mowing Height: The recommended height at which grass should be cut to promote healthy growth.

• Nematodes: Microscopic worms, some of which can damage grass roots.
• Nitrogen: An essential nutrient for lawn health, promoting green and leafy growth.

• Overseeding: Spreading grass seed over an existing lawn to improve density or repair damaged areas.
• Organic Lawn Care: Lawn care practices that avoid synthetic chemicals, relying on natural methods.

• pH: A measure of soil acidity or alkalinity, crucial for determining nutrient availability.

• Post-Emergent Herbicide: A chemical applied to weeds after they have already sprouted.

• Quackgrass: A perennial weed grass that is invasive and difficult to control.

• Ryegrass: A fast-growing grass often used for overseeding or temporary coverage.
• Root Zone: The area of soil where grass roots are concentrated.

• Sod: Pre-grown grass and soil sold in rolls for instant lawn coverage.
