What are the best wood species for planters in regions with frequent earthquakes?

When choosing wood for planters in areas with frequent earthquakes, durability and flexibility are key. The best wood species for such conditions include cedar, redwood, and teak. Cedar is lightweight yet strong, with natural resistance to rot and insects. Redwood is similarly durable and can withstand seismic shifts due to its fibrous structure. Teak, though heavier, offers exceptional stability and longevity. Avoid brittle woods like pine, which may crack under stress. Opt for thicker planks and reinforced joints to enhance earthquake resistance. These choices ensure your planters remain sturdy and attractive, even in unstable environments.
