Understanding Berm Fill Material and Planting Intent

How NOT to build a BERM.
What happens here
Before planting on berms, it is critical to consider the type of fill material and the intended planting style. For controlled planting (specific plants in distinct locations), structural fill is recommended as it resists settlement, ensuring plant stability. Conversely, if the goal is wild, spreading growth across the berm, organic material is preferred. However, organic material will experience more differential settlement over time, leading to an uneven appearance. Therefore, avoid compacting the berm soil if promoting natural root spread, as compacted soil hinders root growth and can 'choke' plants.
Goal: Make informed decisions on berm construction based on planting goals
Tools and materials
- Organic Material — Creating fertile berms that encourage wild growth and spreading, but may settle more
- Structural Fill N/A — Creating stable berms that resist settlement, suitable for controlled planting
