Mastering the perfect lawn starts with soil depth and strategic turf placement
In short: Laying a new lawn is more than just rolling out grass. Success depends on understanding your garden's specific light conditions, preparing the soil depth, and using a brickwork pattern to prevent water runoff. Follow these expert techniques to ensure your new turf establishes deep roots and stays green all year.
Choosing the right grass variety is the first hurdle in establishing a healthy lawn. According to Neil, an expert with decades of experience in the turf business, your garden's aspect is the most critical factor. While varieties like couch grass and zoyzia are popular, they may struggle in shaded areas. For spots with limited sunlight, buffalo, ryegrass, or zoyzia are better choices because they tolerate shade well. Before planting, it is essential to prepare the ground by removing existing vegetation and tilling the soil. Aim for a topsoil depth of 150mm to 200mm, as this depth is vital for long-term drought tolerance.
Soil quality dictates how well your lawn will thrive. Conducting a pH test allows you to adjust nutrient availability using agricultural lime or gypsum. Gypsum is particularly useful for heavy clay soils, as it helps break the soil apart and improves drainage. Once the ground is prepared, focus on creating a level surface. A flat foundation prevents the mower from dipping into hollows and scalping the grass during future maintenance. When calculating how much turf to order, measure your area and add a 5% buffer to account for edges, corners, and curves, ensuring you avoid using small, easily dried-out pieces.
The installation process requires precision to ensure the turf survives. Lay your rolls in a brickwork pattern, working across the slope to prevent water from forming channels between the seams. Keeping the rolls snug against one another is crucial. After laying, tamp the turf down firmly to guarantee direct contact with the soil, which allows the roots to access moisture from the underlayer. Avoid walking on the new lawn until the roots have fully connected to the soil. For the first mow, remove only one-third of the leaf, starting with a light trim before transitioning to a weekly schedule.
