Calamondin Orange Fruit Drop: Light Deficiency in Toronto Apartment

Your calamondin in a 6th-floor Toronto apartment with only 1–2 hours morning sun is dropping fruit due to severe light deficiency. Bright indirect light isn't enough—citrus needs intense, direct light for fruit retention and flowering.

Realistic Assessment

• Current light may sustain foliage but not fruit/flowers.
• Supplement with strong LED grow light (full spectrum, 30+ watts) 6–12 inches above, 12–14 hours daily.
• Without supplemental light, treat as foliage plant; enjoy occasional fruit as bonus.

Hand Pollination

Flowers have both stamens (pollen) and pistil (fruit). Use a cotton swab to transfer pollen between flowers.

Light is the limiting factor—address it or adjust expectations.
