What is the purpose of setting a plant on a pedestal of firmed soil?

Setting a plant on a pedestal of firmed soil primarily serves the purpose of maintaining a proper height above grade, which is critical for the overall health of the plant. When a root ball is placed too deeply in the soil, it can lead to suffocation, poor drainage, and an increased risk of root rot. By ensuring that the plant is positioned correctly and elevated slightly, it facilitates adequate air circulation and proper moisture levels around the roots.

Additionally, this technique helps to ensure that any settling that may occur over time does not bury the root ball deeper than intended. Proper height allows the plant to establish effectively in its new environment, promoting better growth and development. This practice effectively combines elements of landscape management with horticulture, ensuring not only aesthetic appeal but also plant vigor and longevity.
