Harvesting Banana
When ready: Fingers (individual bananas) are plump and rounded (not angular/ridged). Flower petals at tip of each finger dry and rub off easily. Wait until fingers start to turn slightly yellow on the bunch, OR harvest when full-sized but green and ripen indoors.
How to harvest: Cut entire bunch with machete or heavy knife. Support bunch weight as you cut. They're heavier than you think (15-40kg). Hang in cool shady spot to ripen. Ripen faster in paper bag with ethylene-producing fruit (apple).
