Harvest Tips
Pick fruit when fully colored orange and slightly soft to touch; twist and pull gently or use pruning shears. Harvest typically December through March. Fruit can remain on tree for weeks after ripening without quality loss. For best flavor, allow to ripen fully on tree; color is the primary indicator of readiness. Small size and thin skin make these ideal for hand-peeling.
Fun Facts
- 🌱 Lunch Box Orange trees are among the most compact citrus varieties available, often reaching only 8-10 feet tall and naturally dense and shrubby, making them ideal for small spaces and containers.
- 🌱 The fruits are seedless due to hybrid genetics and parthenocarpy (fruit development without fertilization), making them user-friendly for children and eliminating the need to remove seeds when eating.
- 🌱 Citrus flowers are highly fragrant and attract pollinators; even a single tree in bloom can perfume an entire garden, and the blossoms are traditionally used to make orange blossom water for culinary and perfume applications.
