How does eucalyptus wood’s resistance to rot compare to pressure-treated pine?

When choosing lumber for outdoor projects, rot resistance is a critical factor. Eucalyptus wood, known for its natural durability, offers impressive resistance to rot and insects due to its high oil content and dense grain. In contrast, pressure-treated pine is chemically treated to resist rot, fungi, and pests, making it a popular choice for decks, fences, and other exterior applications.

While eucalyptus wood is naturally resistant without chemical treatments, pressure-treated pine relies on preservatives like copper-based compounds to achieve similar durability. Eucalyptus may last longer in harsh conditions but can be more expensive and harder to source. Pressure-treated pine, widely available and affordable, requires periodic maintenance to sustain its rot resistance over time.

For long-term outdoor use, eucalyptus wood is a sustainable and low-maintenance option, whereas pressure-treated pine provides a budget-friendly alternative with proven performance. Your choice depends on budget, availability, and environmental preferences.
