What Organic Mulch Does and How to Use It
Organic mulch is a new type of urban greening surface covering material that has developed rapidly at home and abroad in recent years. The use of organic mulch to cover bare soil has gradually become a landscape ecological and environmental protection trend. Organic mulch can be applied to all bare surfaces such as trees planted in new urban green spaces, gardens, flower beds, and surrounding shrubs.
The raw materials of organic product mulch mainly come from garden waste and woody waste in forest residues. It is one of the ways to use landscaping waste and forest residues in a circular economy. Common organic mulches include dyed and colored organic mulches. mulch, pine bark mulch, fermented husks, etc.
Pine bark organic mulch can be used in: landscaping, municipal streets, tree pits, flower beds, potted green plants, simulated green plants, flower border landscaping, window sets, playgrounds, coffee shops, clothing stores, leisure bars, etc. Laying in various environments.
The role of laying organic mulch:
1. Maintain soil moisture, adjust soil temperature, organic mulch can increase water permeability and water holding capacity, reduce water evaporation, slow down the rise of low temperature in spring and summer, maintain soil temperature and humidity, and play a role in reducing soil erosion and compaction .
2. Increase soil nutrients, organic mulch will release many mineral nutrients during the decomposition process, increase soil organic matter, and promote plant growth.
3. Inhibit the growth of weeds Organic mulch can effectively block the sun, so that weeds cannot grow on the soil surface, and form a variety of microbial groups through physical action and pressure, so that weed seeds rot quickly and cannot germinate.
4. Beautify the environment. Organic mulch can cover loess and absorb dust. By matching different landscape plants against each other, it can improve the landscape effect, make the urban green landscape more attractive and increase the aesthetic effect.
How to use organic mulch: Mastering the appropriate thickness of the organic mulch is an important part of laying the organic mulch. According to various research practices, the most suitable laying thickness of the organic mulch is 5~8cm. If the mulch is too thin, it will not retain moisture and control weeds. If the mulch is too thick, it may cause poor water permeability or excessive soil moisture and poor ventilation, which will affect the growth of trees. Only by laying reasonable organic mulch can it play a greater role.
