Preparation is key
It is always advisable to make a sketch in advance – no matter how large or small a garden may be. In the sketch, draw the boundaries of the garden, the house, obstacles, paths, bushes, flower beds, trees, furniture, large ornaments and areas of water. If you have an overview of your garden, you'll be able to plan out on paper how and where you ideally want to lay the boundary cable before you get started.
If the planning is in place, you should – ideally before you lay the cable – manually trim any grass that has grown higher than 6 cm one last time with a lawn mower or trimmer. If you then programme the mowing times sensibly, the grass should not be able to grow this tall again over the entire garden season. The new robotic lawn mower takes care of this at regular intervals. Before it is ready to get going, loose objects such as toys should also be removed from the lawn.
