Different weed control methods are needed for different situations. Annual weeds that grow in small flower beds, for example, can easily be uprooted.
Sometimes, for example, when replacing perennial lawns with ground cover, a systemic herbicide such as Roundup may be needed, although reluctantly. However, there are special situations where weeds that are grown under controlled conditions are preferable to completely eradicated through the use of weed killers.
This can be applied to non-planted areas in the garden which for one reason or another still needs to be cultivated. This can range from a small room to a herb garden, a large area designated as a collection of fruit trees, or an entire garden plot. In cases where the area needs to be planted in the future rather than now, it is best to control the weeds by mowing occasionally.
Regular mowing, either with a lawnmower or with mechanical tape (weeds), prevents weeds from multiplying or locates seeds, which keeps their spread under control. But what can be gained from them instead of getting rid of them altogether? Where is the advantage that they too can grow under controlled conditions?
The question could also be asked, “What’s wrong with keeping the area completely weed-free?” However, there is no shortage of resources to achieve this goal. Regular spraying with a suitable herbicide, for example, can work efficiently and cheaply. The answer lies in the fact that the future health and fertility of the soil depends largely on the fact that it is protected from erosion on the one hand and on the percentage of organic matter it contains on the other.
