Find where the growth starts
Look closely without pulling up the lawn. Growth can be rooted in soil or debris on the surface, along an edge, in a joint or beside planting. Note whether the backing is visible, a seam has opened or a border has spilled onto the grass. Photographs of the wider area and a close view help distinguish these possibilities.
Do not assume a recurring weed problem proves that the membrane is absent or defective. Equally, do not dismiss an open seam or lifted edge as routine cleaning. The right remedy depends on where material has collected and whether the installation remains secure.
What the membrane is for
Our garden installations include a non-woven geotextile membrane as part of the specified construction. Its role depends on its location and the installation design. It does not create a sealed roof above the lawn and cannot prevent wind-blown seeds, leaves or soil from landing on top.
Artificial grass is a low-maintenance surface. Claims such as weed-proof or maintenance-free overlook the need to clear debris, inspect perimeters and manage adjacent planting over time. Ask what a quotation includes rather than relying on a guarantee implied by a material name.
Remove growth without damaging the lawn
Follow the supplier’s aftercare instructions and work carefully around joins. Remove accumulated organic material with appropriate tools. If a plant resists removal or appears to come through a gap, stop and request advice rather than tugging hard enough to lift the grass.
Use a treatment only if its label and the grass supplier confirm suitability for the artificial lawn and surrounding surfaces. Keep children and pets away as directed. Do not mix chemicals, pour boiling water onto synthetic fibres or use a flame weeder.
When the issue needs repair
A loose perimeter, failed joint or uneven base can require work beyond cleaning. Tell Saygrass about the age of the lawn, installation history, recurring locations and any previous treatments. See repairs and replacement for how an assessment starts.
We use only our own supplied grass for new installations and grass repairs. A colour or pile match with an aged lawn is not guaranteed. For routine cleaning, send photographs, area and address; for replacement or base work, a site survey may be needed.
