What are the differences in thermal insulation between natural and synthetic rattan outdoor tree boxes?

When choosing outdoor tree boxes, thermal insulation is a critical factor, especially for protecting plant roots from extreme temperatures. Natural rattan, derived from palm plants, offers moderate insulation due to its porous structure, which allows air circulation but may not retain heat as effectively. Synthetic rattan, made from polyethylene or resin, provides superior thermal insulation because of its dense, non-porous composition, which helps maintain stable soil temperatures.

Natural rattan is biodegradable and eco-friendly but may degrade faster under harsh weather, reducing its insulating properties over time. Synthetic rattan, while less eco-friendly, is highly durable and retains consistent insulation even in fluctuating climates. For gardeners in colder regions, synthetic rattan is often the better choice, whereas natural rattan may suffice in milder environments.

Ultimately, the decision depends on your climate, sustainability preferences, and long-term maintenance goals. Both materials offer unique benefits, but synthetic rattan generally outperforms in thermal insulation and longevity.
