What does coniferous mean? Did you know? That word again is this sustainable? That 80% of all wood used in the UK comes from abroad?

11. Answers Wood Seasoning is the process of removal of moisture from Timber. Coniferous forests are made up mainly of cone-bearing or coniferous trees, such as spruces, hemlocks, pines and firs. These trees have small needle-like leaves that stay green all year around, shallow root systems, and soft wood. Deciduous trees are many hardwood trees the list of which comes next
