Building Garden Features with Cinder Blocks

Cinder blocks are a favorite for gardeners because they are durable, inexpensive, and don't rot like wood. Whether you're building a low border wall or a decorative planter, calculating your blocks correctly ensures your project stays on budget.

Why Use Cinder Blocks in the Garden?

  • Longevity: Concrete blocks withstand soil moisture and pests for decades.
  • Thermal Mass: Blocks absorb heat during the day and release it at night, which can help plants in cooler climates.
  • Modularity: Easy to stack and rearrange if you decide to change your landscape design.
