Divided yarrow (Achillea millefolium) is a popular perennial plant known for its feathery foliage and clusters of colorful flowers. However, weeds can quickly invade the area around yarrow, competing for nutrients and water. Proper mulching is an effective way to suppress weeds and promote healthy yarrow growth.
Understanding the Importance of Mulch
Mulch acts as a protective barrier that covers the soil surface, reducing weed germination and growth. It also helps retain soil moisture, regulate temperature, and add organic matter to the soil as it decomposes. Choosing the right mulch and applying it correctly are essential steps in weed control around divided yarrow.
