What are the fire resistance properties of pine and cedar outdoor planters?

When choosing outdoor planters, understanding the fire resistance properties of materials like pine and cedar is crucial for safety and durability. Pine is a softwood with moderate natural fire resistance due to its resin content, but it is more flammable compared to cedar. Cedar, another softwood, contains natural oils that enhance its fire resistance, making it a better choice for areas prone to high temperatures or fire hazards. Both woods can be treated with fire-retardant chemicals to improve their performance. However, untreated cedar generally outperforms pine in fire resistance. For long-term outdoor use, cedar planters are often recommended for their combination of durability and enhanced safety. Always consider local fire regulations and treatment options when selecting wood for outdoor planters.
