How does rattan’s moisture content at harvest affect outdoor flower box durability?

The moisture content of rattan at the time of harvest plays a crucial role in determining the durability of outdoor flower boxes. Rattan, a natural material widely used in garden furniture, undergoes significant changes based on its initial moisture levels. If harvested with excessive moisture, rattan may shrink or warp as it dries, leading to cracks and structural weaknesses in flower boxes. Conversely, properly dried rattan resists weathering and maintains its shape over time.

To ensure longevity, manufacturers should harvest rattan at optimal moisture levels—typically between 12-15%—before crafting outdoor products. Proper drying and treatment further enhance resistance to humidity, rain, and UV exposure. By understanding the relationship between moisture content and durability, gardeners and furniture buyers can select high-quality rattan flower boxes that withstand outdoor conditions for years.
