Wood seasoning is a critical step in timber processing that directly affects the durability, strength, and dimensional stability of wood products. This study reviews global wood seasoning practices, focusing on how methods vary based on species-specific properties such as density, fiber structure, moisture content and shrinkage rates. Common techniques like air drying, kiln drying, and advanced methods (vacuum, steam, hybrid) are compared for their effectiveness across both hardwood and softwood species. The research highlights the importance of matching drying strategies to wood characteristics to minimize defects such as warping, cracking, and fungal attack or decay. Drawing from international best practices, the study offers practical recommendations for Nepal’s forest product sector, where diverse species and climatic conditions require locally adapted solutions. Species such as Shorea robusta (Sal), Dalbergia sissoo (Sissoo), and Alnus nepalensis (Uttis) are considered for their seasoning challenges. The study suggests promoting low-cost solar kilns and developing species-specific drying schedules. Additionally, strengthening technical capacity to improve timber quality, reduce post-harvest loss, and support a more sustainable, climate-resilient wood industry in Nepal.
