What are the best woods for planters intended to support climbing vines?

When selecting wood for planters intended to support climbing vines, durability and resistance to rot are key factors. Cedar and redwood are among the best choices due to their natural resistance to moisture, insects, and decay. Cedar, in particular, is lightweight yet sturdy, making it ideal for vertical structures like trellises. Redwood offers similar benefits with a rich, attractive color. Pressure-treated pine is another option, though it requires chemical treatments to enhance longevity. Avoid softer woods like untreated pine or fir, as they degrade quickly when exposed to moisture. For a sustainable and long-lasting planter, opt for naturally resilient woods like cedar or redwood to ensure your climbing vines thrive.
