What are the planting methods used to establish a new lawn?

1. Cuttings, separation, division, and grafting

2. Seeding, sodding, separation, and sprigging

3. Plugging, cuttings, division, and grafting

4. Layering, seeding, and transplanting

The correct answer is: Seeding, sodding, separation, and sprigging

The methods used to establish a new lawn primarily include seeding, sodding, separation, and sprigging, which effectively support the creation of a robust and healthy grass cover. Seeding is one of the most common methods, involving the dispersal of grass seeds over a prepared soil surface. This method allows for a wide variety of grass species to be used, accommodating different climates and soil types. Sodding involves laying down pre-grown grass rolls or squares, providing an instant lush lawn. This technique helps to reduce erosion and weed competition while establishing a lawn quickly, making it a preferred choice for those looking for immediate results. Sprigging is another valuable method, especially for warm-season grasses. It entails planting small shoot sections or stolons that develop roots and grow into a full lawn over time. This method can be both cost-effective and environmentally friendly, as it can utilize existing grass in the area or from specific cultivars. While other options mention methods like cuttings and layering, which are not typically used for lawn establishment, the techniques listed in the correct answer specifically focus on methods suitable for growing grass lawns efficiently.
