Q: Why do people paint the trunks of their citrus trees white?
A: HA! At last, a question we actually knew the answer to without having to look it up or ask somebody. It’s to protect them from the sun.
We are soooooo smart.
To celebrate, we asked an actual newcomer in the office if she knew why citrus trunks are painted white, and she said it was to repel insects. These comical newcomers.We were going to laugh at her until we remembered she is much higher up the food chain than us and holds what passes for our career in her elegant and well-manicured hands. So we didn’t laugh.
Just to double-check, and to look busy, we called Ralph Backhaus, a professor of plant biology at Arizona State University.
