New mulch applications are essential for several reasons. Over time, existing mulch decomposes, losing its effectiveness in suppressing weeds, conserving moisture, and moderating soil temperature. Fresh mulch replenishes this lost material, ensuring continued benefits for your plants. Additionally, new mulch can improve the aesthetic appeal of your landscape, giving it a fresh, vibrant look.
In summary:
Replenishes decomposed mulch: Maintains the benefits of weed suppression, moisture retention, and temperature regulation.
Enhances appearance: Provides a fresh, clean look to your landscape.
