What is a common method used for controlling weeds?

Mulching to block sunlight is a common and effective method for controlling weeds. This practice involves applying a layer of organic or inorganic material on the soil surface around plants. The primary goal of mulching is to suppress weed growth by physically blocking light, which is essential for weed seed germination and growth. Without sufficient exposure to sunlight, many weed species struggle to establish themselves, thereby reducing competition for nutrients, water, and space among desired plants.

Additionally, mulching can offer other benefits, such as maintaining soil moisture, regulating soil temperature, and providing organic matter as the mulch breaks down, which ultimately improves soil health and fertility. This method is environmentally friendly and often preferred in sustainable landscaping practices because it minimizes the need for chemical weed control and promotes a healthier ecosystem in the garden or landscape.
