Layers of mulch suppress weed growth and keep the soil moist. Chopped tree bark, a waste product of forestry, serves as a substitute for a warming layer of leaves or grass.

Bark Mulch: Protective cover for the soil

Bark mulch suppresses weeds very well and blends in perfectly with the natural appearance of the garden. However, the material also has disadvantages, as it removes nitrogen from the soil and acidifies it as it rots. However, you can compensate for the loss of nitrogen by fertilizing, for example with horn shavings (€32.93).

How quickly the bark mulch decomposes depends on the granulation: the larger the pieces, the slower they decompose. To effectively suppress weeds, you should apply a layer of mulch at least five to seven centimeters thick. Re-mulch once a year to compensate for the decomposed volume of the bark mulch layer.

Grass clippings as an alternative mulch material

Some experts recommend not mulching young plants with bark mulch. Use dried grass clippings instead. This layer of mulch also protects the soil from the effects of the weather and supplies the cherry laurel with nutrients as the material decomposes.

tips and tricks

Mix the mulch (€239.00) with leaves of comfrey or nettle. The valuable ingredients of the plants strengthen the cherry laurel in a natural way when mulching.
