They do not get stuck in the profiles of shoe soles. Renew the floor overlay over the years as the rotting components get slippery and thinner.
Soil protection
In the bed, bark mulch proves to be an optimal cover and prevents soil erosion and excessive water loss due to strong sunlight. It is enough if you spread a layer five to seven centimeters thick on the substrate. Make sure the grain is coarse so that oxygen can circulate.
