Indoor Navel Orange Tree: No Fruit = Light + Pollination Deficit

100s of flowers but no fruit for 2 years on an indoor orange tree = two problems:

1. Insufficient light: Fruit set requires high photosynthesis (full sun).
2. Poor pollination: No insects indoors; hand-pollination is unreliable.

Solution

Move outdoors in spring. Solves both: full sun + bees. Tree will fruit reliably.

If Indoors Only

• Maximize sun (south/west + grow lights).
• Hand-pollinate: transfer pollen with small brush between flowers daily during bloom.
• Expect low success; fruit may drop.

Citrus are outdoor plants. Indoor culture is for foliage, not harvest.
