Does your lawn have more dead grass than living? Experts share whether you can simply lay turf over grass and start afresh
Briefly

Laying turf over an existing lawn is possible but not advisable due to difficulties in rooting and potential weed propagation. The old lawn’s compacted soil further hinders root establishment. For successful installation, experts recommend cutting the existing grass short, aerating the soil, and adding topsoil. However, the optimal approach is to remove the old lawn completely to ensure proper conditions for the new turf. This involves using garden tools to clear the area and prepare the soil appropriately for new grass to thrive.
While it is possible to lay turf on existing grass it's not recommended. The new turf will have a harder time rooting and becoming established.
If you lay turf over an old lawn, the new grass will struggle to reach the soil underneath and root properly. The soil of your old lawn is also likely to be compacted.
It’s essential that you cut the grass really short first and pull up any weeds. Aerate the ground with a garden fork to improve drainage.
The best method is to dig up and remove all the grass and weeds from your old lawn first, ensuring the soil is not compacted before laying new turf.
