Understand Planter Drainage Mechanism

What happens here

The speaker elaborates on the intelligent design of the fabric liner system. Its primary function is two-fold: firstly, it allows moisture (from rain or irrigation) to freely enter the soil, ensuring that the root balls of any plants placed in the planter receive adequate hydration. Secondly, it provides a clear exit point for any excess water. This surplus water will permeate through the underside of the fabric and then flow into the existing gravel drainage system that runs along the back of the main retaining wall. This prevents waterlogging in the planter while effectively managing drainage and protecting the retaining wall structure.

Goal: Comprehend how water drains from the planter box.
