Harvest Tips
Ponderosa lemons typically ripen 6-9 months after flowering, usually from late winter through spring. Harvest when fruit turns fully yellow and slightly yields to gentle pressure. Clip fruits from tree using pruners rather than pulling to avoid branch damage. Fruits can stay on tree for several weeks after ripening without quality loss. Store at room temperature for up to 2 weeks or refrigerate for 4-6 weeks.
