Allow pomelos to ripen on the tree if you are growing them yourself. Leave the fruit in place as long as possible before harvesting. The trees may flower and fruit more than once per year, but the main crop of fruit begins to ripen on the trees around November. The rind yellows as the fruit ripens.

How do you know when a pomelo is ripe?

Since the exterior color of pomelos can vary widely, the best way to tell if a pomelo is ripe is to choose one that has a grassy, floral scent and feels heavy for its size. Look for shiny, unblemished skin; if it's puckered or feels dry, the fruit most likely will be, too.

Are pomelos ripe when green?

However, no matter the size, the best pomelos are heavy and aromatic, with blemish-free skin ranging from green to yellow. Pomelos become sweeter off the tree, so allow green-skinned fruit to ripen to yellow, although Thai varieties can remain green when ripe.
