After the heavy thunderstorms there is a lot of loose dead wood and fallen trees can block paths. Please be careful and do not rest under scrawny trees.

Due to the ongoing heat wave and drought, there is a considerable risk of forest fires in the canton of Zurich (level 3 out of 5). We kindly ask you not to light fires in the Sihlwald. You may use the marked fireplaces in the Langenberg Wildlife Park. Please always extinguish the fire completely.

Raised bed

A raised bed can also be used to create a biodiverse area in small spaces such as on the balcony or patio, or if the available space is sealed.

Material

Compost grid
Wooden boards
bubble wrap
Wall gravel or expanded clay
Soil and humus
Native wild plants

Structure

Place the cylindrical compost grid in the desired location
Line the inside of the compost grid with wooden boards cut to the height of the grid
Cover the inside of the wooden boards with the bubble wrap
To prevent waterlogged soil, fill the cylinder to ¾ height with wall gravel or expanded clay. The latter is lighter than gravel.
- Fill the top layer with a mixture of wall gravel and soil and hummus – depending on the location and plant with more or less soil and humus (follow the instructions for the plants)
Plant with native wild plants in spring or fall
The raised bed must not be too large on the balcony because it will be too heavy (statics). Ready-made raised beds or kits are available from specialist retailers
