Keeping weeds in the garden is an effective way to protect and improve soil quality. In the past, farmers always had the notion that weeds were the enemy, because they would compete with crops for nutrients. And it is always difficult to get rid of weeds by digging or spraying. But this concept gradually changed when gardeners realized the special benefits that weeds bring to the soil.
1. Can measure nutrition and water in pot
This weed is a water meter and fertility meter, which can observe the dry and wet conditions of potting soil through weeds and provide reference information for daily watering. Usually erect grass indicates there is no shortage of water, if the grass withers means the pot is relatively dry.
At the same time, weed roots are generally relatively well developed, reflecting the soil fertility of the basin more quickly.
In addition, grass helps regulate soil nutrients, when mowed or naturally killed, grass returns nutrients to the soil. Grass roots, when decomposed, increase the organic content in the soil, helping the soil to become richer and more fertile.
2. Reflects the degree of root rot
Some potted plants have root rot, and even weeds can prevent root rot. Bonsai root rot disease mainly occurs in summer climates with high temperatures, high humidity, continuous rain clouds and alternating sunlight.
Grassroots help the soil to become loose and aerated, bringing a lot of O2 and CO2 to the deep layers of the soil, helping plant roots breathe and absorb nutrients more easily.
In addition, it also helps the soil retain moisture better, carries water and nutrients deeper, limits evaporation of water in hot weather, and prevents root rot when there is too little or too much water.
3. Improve soil quality
Keeping weeds at bay helps create a favorable environment for soil microorganisms to thrive, which improves soil quality more effectively. Helps protect plants from fungal attack.
Covering the soil helps limit alkaline metal leaching and also contributes to stabilizing soil pH. In addition, some other species have the ability to repel nematodes, harmful insects or attract natural enemies.
For example weeds can take advantage of high salinity but the main crop is difficult and adversely affected. Weeds can survive well in soils with few nutrients, such as reeds. Therefore, this weed is a good indicator of soil fertility.
