8 Dec. 2020: Apple propaganda, cladoptosis

A few weeks ago I learned that the “apple a day” thing started as propaganda to encourage people to eat excess apples during prohibition because they could no longer be made into hard cider.

I also learned that a lot of trees naturally shed their branches (cladoptosis) when they deem them an inefficient use of resources. We don’t have to prune trees to keep them healthy; we only prune them to satisfy our own aesthetic taste.

It takes 40-50 gallons of maple sap to make a gallon of maple syrup.
