Harvest Tips
Fruits are ready to harvest when fully yellow (40-60 days after flowering) and slightly soft to touch. They should release a sweet, aromatic fragrance. Granadillas can be hand-picked by gently twisting or cut with pruners. Fruits continue to ripen slightly after harvest but taste best when vine-ripened. Store at room temperature for a few days or refrigerate for up to 3 weeks.
