What can be considered a method to control weeds when cultivation isn't an option?

Mulching is an effective method for controlling weeds when cultivation is not feasible. By applying a layer of organic or inorganic material on the soil surface, mulching helps suppress weed growth in several ways. It blocks sunlight from reaching the soil, which is necessary for weed seeds to germinate. Additionally, it helps retain soil moisture and can improve soil quality as organic mulch decomposes.

While other options like plastic barriers and chemical soil sterilizers can also manage weeds, they come with certain limitations or environmental concerns. Plastic barriers, for example, may prevent water and nutrients from reaching the soil, which could be detrimental to desirable plants. Chemical soil sterilizers can alter soil chemistry and potentially harm beneficial microbiota, making them less favorable for sustainable practices.

Planting invasive species is not a method of weed control and generally leads to greater ecological issues by disrupting local ecosystems. In contrast, mulching leverages natural processes and promotes a healthier growing environment while effectively managing weed populations.
