What is one method to control weeds in a landscape?

Mulching is an effective method for controlling weeds in a landscape for several reasons. By applying a layer of mulch, you create a physical barrier that blocks sunlight from reaching the soil surface, which is essential for weed seed germination and growth. This suppression of light can significantly reduce the number of weeds that sprout and thrive in the landscape.

Additionally, mulch helps retain soil moisture, which can promote healthy plant growth while simultaneously making it more difficult for weed seeds to establish. Organic mulches, such as bark chips or straw, also provide added benefits, such as improving soil structure and contributing nutrients as they decompose.

The other methods mentioned do not effectively control weeds. Increased nitrogen fertilization may encourage the growth of both desirable plants and weeds, leading to more competition. Overwatering can create more favorable conditions for weed growth by promoting damp environments, while ignoring weeds allows them to flourish unchecked, competing with desired plants for resources. Thus, mulching stands out as a proactive and beneficial approach to weed management in landscaping.
