What are the differences in erosion resistance between granite and concrete planters?

When choosing planters for outdoor use, erosion resistance is a critical factor. Granite and concrete are two popular materials, but they differ significantly in durability. Granite, a natural stone, is highly resistant to erosion due to its dense structure and minimal porosity. It withstands harsh weather, UV rays, and moisture with minimal wear over time. Concrete, while durable, is more porous and prone to cracking or chipping in extreme conditions. Over time, water absorption can weaken concrete, leading to faster erosion compared to granite. For long-term outdoor use, granite planters generally outperform concrete in erosion resistance, making them a superior choice for harsh climates. However, concrete remains a cost-effective option for milder environments. Consider your local weather and budget when selecting the best material for your needs.
