Transforming a natural lawn to an artificial grass haven is a process many homeowners and gardeners consider due to the numerous benefits it offers. Unlike traditional maintenance-heavy lawns, artificial grass requires minimal attention, provides an all-year-round lush appearance, and is cost-effective in the long run. However, laying artificial grass directly over existing grass is not as simple as it may first appear and requires careful consideration and execution.

The initial and most crucial step in this transformation is thorough preparation. Foremost, it's imperative to address the natural grass beneath. Because artificial grass doesn't allow for natural growth underneath, failing to remove or adequately treat the existing grass could lead to an uneven surface, causing bumps and potentially damaging the artificial turf over time. One recommended approach is to apply a weed killer to the existing grass and remove the top layer of turf, ensuring a flat base.
For enhanced longevity and consistency in appearance, installing a proper sub-base is key. A well-structured sub-base like crushed gravel or sand not only provides a solid foundation but also facilitates excellent drainage, crucial for preventing water pooling on the surface. Ideally, compact the sub-base layer to about three to four inches to create a stable and firm foundation. This base must be levelled accurately to prevent any irregularities in the artificial turf that could affect both its aesthetics and usability.

Following the installation of the sub-base, it's time to add a layer of geotextile fabric. This specialized layer plays an essential role in preventing weed growth through the artificial turf, a critical step to maintain its impeccable look. Moreover, the fabric provides an additional layer of separation between the base and the grass, contributing further to drainage efficiency.

When laying the artificial grass, precision is key. Measure the area meticulously and cut the grass accordingly, ensuring that the pile direction aligns consistently throughout the area for a uniform look. It's advisable to let the grass sit in place for a few hours before final fitting, allowing it to acclimate and any creases to settle. Secure the turf using landscaping pins or a high-quality adhesive, especially at the seams, to avoid any movement or separation over time.
The infill material is another pivotal part of this process. Silica sand is commonly recommended due to its weight, adding a necessary layer that holds the grass down and keeps the blades upright. The infill not only stabilizes the turf but also provides the cushioning effect underfoot, simulating the natural feel of a traditional lawn.
Lastly, once the installation completion, a thorough brushing of the grass blades is essential. This grooming step helps in standing the blades upright and gives the artificial lawn its natural lush appearance. Routine maintenance, though minimal, involves regular brushing and occasional removal of debris to maintain its pristine condition.
Embarking on the journey of laying artificial grass over grass demands diligence, attention to detail, and understanding of each step's significance. By adhering to these practices, homeowners can achieve a beautiful, durable, and practically maintenance-free synthetic lawn. This method not only ensures an enviable yard but also aligns with eco-conscious goals by reducing water usage and eliminating the need for harmful lawn chemicals.
