What promotes plant health to suppress weed growth through non-chemical methods?

Cultural control is focused on promoting plant health through various practices that create conditions favorable for desirable plants while making it less favorable for weeds to thrive. This method involves practices such as crop rotation, proper fertilization, mulching, and adjusting planting densities. By enhancing the strength and resilience of the desired plants, cultural control can effectively suppress weed growth, as healthier plants can outcompete weeds for sunlight, nutrients, and water.

In contrast, biological control relies on the use of natural predators or pathogens to manage weed populations, which, while effective, does not directly promote the health of desired plants in the same way. Mechanical control involves physical removal of weeds through methods such as mowing or tilling, and while it can be effective, it does not focus on enhancing plant health. Integrated pest management encompasses a holistic approach combining multiple strategies, including biological, cultural, and mechanical controls, but may not specifically focus on the non-chemical promotion of plant health as directly as cultural control does.
