Bark mulch is the best choice for use as a weed suppressant as it inhibits weeds in two critical ways. First, by applying a thick layer covering the soil, bark mulch deprives the weed seeds in the soil, and their resulting seedlings, of the sunlight desperately needed to germinate and thrive.

Applying a thick layer of bark mulch over soil not only prevents sunlight from reaching weed seeds but also helps retain moisture, preventing weed growth.
