How does eucalyptus’s resistance to fungal growth compare to cedar?

When comparing eucalyptus and cedar for fungal resistance, both woods exhibit natural durability but differ in their effectiveness. Cedar is renowned for its inherent antifungal properties, thanks to compounds like thujaplicin, which deter mold and decay. Eucalyptus, while durable, lacks the same level of natural antifungal agents but still resists fungal growth due to its dense structure and high oil content.

Cedar’s superior resistance makes it a preferred choice for outdoor applications like decking and fencing, where moisture and fungi are concerns. Eucalyptus, however, performs well in drier conditions and is often used for furniture and flooring. For long-term fungal resistance, cedar generally outperforms eucalyptus, but both woods offer reliable durability depending on the environment.
