if redwood is naturally rot resistant, why can’t we grow redwoods to build our buildings?

Question

Redwoods are still an evergreen and fast growing. Alternatively, we could put the tannin producing gene in a regular lumber tree to make it naturally rot resistant to be a green alternative to lumber treatments

In: Biology

Answer 1

there might be better reasons, but afaik redwoods don’t grow across a huge range that would allow large-scale cultivation. Their natural, pre-human range is only a narrow strip of the California coast, and up in the Sierra Nevadas.
