How to use our bark products correctly
Benefits and uses at a glance
Our native pine and spruce barks originate from sawmill works. The raw bark obtained there is ground in shredders and then screened, depending on the product quality and particle size required.
The mulch must be stored in a cool, dry place that is protected against the effects of adverse weather conditions. The material must be stored and deployed in such a way that it can’t be eroded by surface or ground-lying water.
Benefits of bark mulch
Bark mulch is ideally suited to cover flower beds. This inhibits the overall growth of weeds – especially useful in hard to reach areas of your garden. This saves you the effort of plucking annoying weeds from the soil and makes your garden look more attractive at the same time.
Climate for microbes
Bark mulch creates an altered climate in the soil. This is ideal for micro-organisms and bacteria, which in turn makes garden soil even more fertile.
Covering planting areas with bark mulch ensures the long-term fertilisation of the soil since a valuable humus develops as the bark slowly decomposes. This contains nutrients for healthy plant growth and improves the structure of the soil, therefore serving as a fully-fledged fertiliser.
Purely creative bark mulch has an impressive effect and is therefore ideal for the preparation of natural gardens and larger outdoor installations.
A bark mulch covering creates a moist and warm climate, which protects the beds against drying out too quickly during the summer on the one hand, and against severe cold during the winter on the other. Bark mulch is therefore a true all-rounder when it comes to protecting garden soil and simply a must for near-natural landscaping outdoors.
Mulch is used on paths to reduce the formation of water puddles and thus minimize the risk of slipping.
Bark mulch uses
For all soils
Bark mulch products are suitable for all soils and can be used all year round. The recommended depth is between 5 and 10 cm, depending on the intended use. The general rule is that too much mulch hinders aeration and the supply of water, whereas layers that are too small limit the effect. Whenever possible, the application should be supplemented after three to four years.
It should be noted, particularly with pine bark which, due to its characteristics, can extract nitrogen from the soil, that we recommend fertilising the soil before mulching by using slowly acting nitrogen fertilisers, e.g. horn shavings. This means that nitrogen deficiencies in the soil are actively prevented and healthy plant growth is ensured.
It is necessary to loosen the soil and remove any weeds before applying the bark mulch. The bark itself is only laid across the surface and not worked into the soil. In our experience, one m3 of bark mulch (1000 l) is usually sufficient for a covering surface of 15 m2. This then corresponds to an average application height of 7.5 cm.
Bark mulch grain sizes
Fine screenings have a particle size of between 00-20 mm and 10-20 mm. They are used when preparing smaller areas in the garden, for the soil coverage of rose beds or when planting shrubs.
Medium and coarse
Medium screenings vary between 00-40 mm, 10-40 mm, 20-40 mm, 00-60 mm, 10-60 mm and 20-60 mm. Bark mulch in these particle sizes is ideal for covering open areas under shrub or tree plantations.
Very coarse screenings have a particle size which can amount to 20-80 mm or 40-80 mm. These sizes are mainly used to create an impact-absorbing surface for play areas, or to cover paths.
Raw bark, also known as peeled bark, originates during the mechanical process of de-barking wood. It is suitable for large-scale application as a bulk material on construction sites, e.g. on highways or as mulching material for nature conservation areas, due to its very coarse structure.
