Sunlight Requirements
Prefers full sun but can tolerate partial shade, making it adaptable to different environments.
Humidity Requirements
Kumquats love humidity just as much as they love the sun, thriving best when levels are around 50–60%, though they are resilient enough to handle levels as low as 40% without much fuss. The easiest way to keep your tree comfortable indoors is with a humidifier, which creates a consistent 'microclimate' of moist air that helps your plant thrive year-round.

Why is my Fukushu kumquat dropping its fruit?
Kumquats hate "soggy feet" but will also drop fruit if they dry out completely. The golden rule is to water deeply, but only when the top few inches of soil feel completely dry to the touch.
