Harvest Tips
Pick fruits when they turn bright yellow and feel slightly soft; can be harvested fully yellow or ripened 3-5 days off-tree at room temperature. Fruits do not continue to ripen after picking if harvested while still greenish. Harvest regularly to stimulate continued flowering and fruiting. Handle gently as skin bruises easily.
