Episode notes
Suckers Drive Commercial Banana Production
- Farmers propagate bananas by cutting suckers and replanting, enabling uniform quality at scale.
- Each sucker becomes one bunch and is managed to optimize flavor and yield across 9–14 month growth cycles.

- The Gros Michel dominated Western exports for decades because it shipped well and tasted great.
- Its thick skin and long ripening period let 19th-century schooners deliver bruise-resistant fruit to U.S. ports like Boston.
