To control weed competition in ground covers during the first few years, which of the following can be used?

The correct choice emphasizes the importance of various methods to control weed competition in ground covers during their establishment phase. Utilizing a combination of strategies can provide a more effective management approach.

Weed barriers are physical sheets or fabrics that prevent sunlight from reaching the soil surface, thus inhibiting weed seed germination and growth. They are particularly beneficial in the early stages of ground cover establishment, as they create a controlled environment for the desired plants to flourish while suppressing unwanted vegetation.

Mulch is another effective method. When applied around plants, mulch conserves moisture, regulates soil temperature, and suppresses weeds by blocking sunlight. Organic mulch can additionally improve soil health as it breaks down over time, providing nutrients to the ground cover plants.

Fertilizers, while typically aimed at promoting the health and growth of the plants, can indirectly help in weed competition management. Healthy, vigorously growing ground covers are better equipped to outcompete weeds for resources such as nutrients, water, and light. Therefore, strategic fertilization can strengthen the desired plants, making them more competitive.

By integrating these techniques—using weed barriers, applying mulch, and providing adequate fertilization—the overall effectiveness in controlling weed competition in the initial years of ground cover establishment is significantly enhanced. This multifaceted approach ensures
