Will these still grow with a limited depth in base

Answer:
Hi Dean, I am struggling a bit to understand why retaining blocks are buried under ground, and why there is not deeper soil nearby to plant in. If the entire area is only covered with 300mm of soil, then the plants might blow over in heavy winds, once they reach the height of 2m or more. Don
