Rotting wood is the process of wood decaying due to the action of fungi, bacteria, and insects. This decomposition occurs when wood is exposed to moisture, which creates an ideal environment for these organisms to thrive. Over time, the wood loses its strength and structural integrity, making it unsuitable for construction or other uses. The signs of rotting wood include discoloration, a spongy texture, and a musty odor. Common causes of wood rot include prolonged exposure to water, poor ventilation, and lack of protective coatings. Preventative measures, such as using treated wood or applying sealants, can help extend the life of wooden structures.
