When choosing between teak and cedar for your garden bench, longevity is a key concern. Both are excellent choices, but their inherent properties lead to different lifespans and maintenance needs.
Teak, a tropical hardwood, is the champion of longevity. Its high natural oil and rubber content make it incredibly resistant to moisture, rot, insects, and cracking. A high-quality teak bench can easily last 25-50 years or more with minimal care. It weathers to a distinguished silvery-gray patina without the need for annual sealing. Its density and tight grain provide superior structural integrity over decades.
Cedar, a softwood, is naturally durable due to its aromatic oils that repel insects and resist decay. A cedar garden bench typically offers a solid lifespan of 15-25 years with proper maintenance. To maximize its longevity, cedar requires more attentive care than teak, including periodic cleaning and the application of a sealant or stain every 1-3 years to protect it from weathering, drying, and color fading.
In summary, for maximum longevity with the least maintenance, teak is the superior investment. Cedar offers very good durability and a beautiful aesthetic at a lower initial cost but demands more regular upkeep to achieve its full lifespan potential. Your choice ultimately depends on your budget and willingness to perform maintenance.
