Coffee plants are grown for a year in a nursery area like this before being transplanted next to the mature trees. It will take 4 years for these plants to start producing coffee fruits.
Coffee trees over 100 years old exist and produce fruit, but a commercial coffee plantation typically replaces 15 year old plants with new plants, and keeps the average age of the coffee plants at around 8 to 10 years old. It’s a constant cycle of planting and cutting down.
