Ecolife® vs. Preserve® FAQs
What are the differences between Ecolife® and Preserve® treated lumber?
Ecolife® and Preserve® are both preservative treatments that can be used for above ground applications of treated wood, such as decking or fencing. Both products are standardized by the American Wood Protection Association (AWPA), indicating that they have demonstrated proven performance. Ecolife® is a newer generation non-metallic preservative with a built-in wood stabilizer which helps the treated lumber look better for longer. The built-in stabilizer helps reduce the amount of cracking, checking and splitting that occurs in wood exposed to the elements.
Are Ecolife® and Preserve® safe for building an in-ground, raised bed vegetable garden?
The construction of an in-ground, raised vegetable garden should use materials designed to withstand ground-contact exposure. So while the preservatives are safe for use near edible garden plants, Ecolife® is not intended or approved for ground-contact exposure. Preserve® can be pressure treated for ground-contact exposure, is equally safe around edible plants, and is available in larger posts such as 4x4's or 6x6's which may work as the retaining wall or perimeter of a raised vegetable garden.
Why is Ecolife® lighter in color than Preserve®?
Preserve® is a copper-based preservative and it is the copper in the preservative which imparts the dark green color. Ecolife® is not a copper-based preservative although there is some colorant added to distinguish the Ecolife® treated wood from untreated wood. The colorant in Ecolife® does not impart a strong green tint on wood after treatment.
