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

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

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.

They’re fast-growing, but you want them to get big, which takes a long time. Also, they seem to be very sensitive to climate. Naturally they only grow in a few isolated patches in California, though apparently the UK has had some success in growing them.

The bottom line is that it’s cheaper to pressure-treat pine than it is to grow redwoods.

We still don’t really use what we’ve planted to make stuff, a tree takes close to a whole human generation to be viable for production. redwoods are also picky about the conditions they grow in compared to other trees

… Who builds buildings from wood?

The older the tree, the more heartwood it has. Heartwood is very rot resistant but is much slower growing than sapwood.

I live in California and you can absolutely buy redwood dimensional lumber at HD and Lowe’s. It’s reasonably priced, used for a lot of outdoor projects.
