Cedar
Pros
- Beautiful natural color and grain. No chemical treatment — safe for food gardens. Lightweight and easy to work with. Naturally resists rot and insects.
Cons
- More expensive — nearly double the cost. Must be sealed regularly to maintain color. Softer — prone to denting from impacts. Heartwood only provides rot resistance.
Pressure-Treated Pine
Pros
- Most affordable option for a full-size pergola. Longest-lasting decay protection. Strongest structural option in given dimensions. Widely available in all needed sizes.
Cons
- Green tint is unattractive when new. Contains chemical preservatives. Heavier and harder to handle. Tends to warp, twist, and check as it dries.
Best Use Cases
Choose Cedar when appearance is a top priority, the pergola is near a vegetable garden or dining area, or you want a chemical-free structure. Choose Pressure-Treated Pine when budget is the primary concern, maximum rot resistance is needed, or you plan to paint or stain the pergola a solid color.
Verdict
For most homeowners, Pressure-Treated Pine is the practical choice — it costs significantly less and lasts longer with proper maintenance. Cedar is worth the premium when natural beauty and chemical-free construction are priorities. If going with PT Pine, let it dry 3-4 weeks before applying a quality stain to improve its appearance.
