The primary method to stop the spread of weeds before they produce seeds is sanitation. This involves removing existing weeds from the landscape, which can prevent them from maturing and producing seeds. By effectively managing the weeds present, particularly before they reach the flowering and seeding stage, you can significantly reduce the seed bank in the soil, thereby preventing future growth and the further spread of weeds.

Sanitation practices may include regular hand-pulling of weeds, mowing them before they flower, or using tools to uproot them completely. This method is crucial because once weeds have produced seeds, they can stay viable in the soil for years, leading to more extensive problems in the future.

Watering, mulching, and fertilization, while they play important roles in landscape maintenance and plant health, do not directly address weed seed production. Watering can promote the growth of both desirable plants and weeds, while mulching can suppress their growth but may not eliminate existing weeds. Fertilization, on the other hand, can further encourage weed growth if not managed carefully. Hence, sanitation stands out as the most effective approach for managing weeds before they have the chance to proliferate through seed production.
