Disadvantages of Using Gravel as Mulch:
When a soil is stressed, air is forced out of the pores in between the soil grains, which results in densification and soil compaction.
The weight and density of gravel mulch puts stress on the soil, preventing it from absorbing moisture and causing runoff and erosion.
Since the soil voids are essential for root development. Gravel that compacts the mineral grains together offers limited space for water and air, which makes it harder for the roots to develop.
Burrowing creatures also find the habitat inhospitable because it is more challenging to pierce the heavier soil.
Other Disadvantages to Consider
- To help boost the organic content of the soil, it cannot be mixed in.
