1. Planning
- Sketch: Start by making a detailed sketch of your garden. Mark all obstacles such as trees, beds, and paths.
- Grass Height: If the grass in the lawn is higher than 60mm, it should be mowed with a lawn mower before using the robotic lawn mower.
- Direction: Lay the boundary wire clockwise around the garden. When you reach obstacles on the lawn, create "islands" counterclockwise around them.
- Corners: Avoid sharp 90-degree corners. Divide them into two 45-degree angles to ensure smooth navigation for the robotic lawn mower.
- Distance Between Islands: There should be at least 1 metre distance between 2 islands as well as to the first island. If the distance is shorter, the obstacles should instead be bounded as one island.
Note the boundary wire must not cross itself at any time.
2. Securing
- Pegging: Use a rubber mallet to secure the boundary wire with plastic pegs every metre. If the ground is hard, it may help to water the lawn first.
- Tension: Ensure that the wire lies tight and close to the ground, right down by the grass roots. There must not be air under the wire.
3. Test Run
- Cutting Height: Set the cutting height on the robotic lawn mower to 60 mm, or remove the blades before the test run. This prevents the wire from being cut.
- Check: Run a test to ensure that the wire is correctly placed and that the robotic lawn mower can navigate without issues.
4. Long-term Solution
- Growth: After a few weeks, the grass will grow around the wire, making it almost invisible.
- Lawn Aerator/Scarifier: If you plan to use a lawn aerator or scarifier, you should bury the wire in a maximum 5 cm deep trench. This protects the wire below the soil surface.
5. Extra Tips
- Under Paving Slabs: The wire can also be laid under paving slabs with a thickness of up to 5 cm.
