Old Growth Timber Definition

Old growth timber refers to wood taken from trees that developed naturally over a very long period of time without modern forestry management. These trees were not planted, rotated, thinned, or harvested on a production schedule. They grew at their own pace, shaped by soil, climate, competition, and time.

Because the growth cycle is long and often slow, old growth timber can show tighter growth rings, higher density zones, and complex internal structure. Those traits influence how the wood mills, how it dries, and how it behaves in long-term use.

At Old Growth Mill, “old growth” is used as a descriptive term, not as a sales label. It describes the life history of the tree, not a guarantee of uniform appearance or performance. Each tree is unique.

Old growth material is finite and non-repeatable. If you are comparing it to commodity lumber, the better comparison is not “better vs worse,” but “unique vs standardized.” Understanding that distinction keeps expectations accurate.
