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 critical role in determining the durability of outdoor flower boxes. Freshly harvested rattan with high moisture levels is more prone to cracking, warping, and fungal growth when exposed to outdoor conditions. Properly dried rattan, however, exhibits greater stability and resistance to weather-related damage.

When rattan retains excess moisture, it can shrink unevenly as it dries, leading to structural weaknesses in flower boxes. Conversely, rattan harvested at optimal moisture levels (typically 12-15%) ensures better longevity, as it minimizes deformation and decay risks. To enhance durability, manufacturers often kiln-dry rattan before crafting outdoor products.

Additionally, selecting rattan with controlled moisture content improves the effectiveness of protective coatings, such as sealants or UV-resistant finishes. This step further shields flower boxes from rain, humidity, and temperature fluctuations. By prioritizing moisture management during harvest and processing, you can significantly extend the lifespan of rattan flower boxes in outdoor settings.

For best results, store rattan in a dry, ventilated area before construction and apply weatherproof treatments regularly. These practices help maintain the material’s integrity and aesthetic appeal over time.
