  1. Plant Characteristics:
    1. The kumquat tree is a small evergreen tree with a round or semi-round crown. The trunk and branches are often covered with backward-facing thorns.
    2. The leaves are elliptical or lance-shaped, leathery, shiny, with fine serrated edges. The upper surface is green, and the underside usually has glandular dots.
    3. Flowers are solitary or in clusters of 3-5, with white petals and a fragrant aroma. The flowering period is from late spring to early summer.
    4. The fruit is round or oval, with thick skin that ranges in color from orange-yellow to reddish-orange. The flesh is juicy and edible.
  1. Distribution:
    1. Kumquats are native to southern China and are primarily found in regions like Fujian, Guangdong, Guangxi, Hunan, and Jiangxi. They grow in subtropical to tropical climates.
    2. Kumquats have been introduced and cultivated in other parts of Asia, Africa, Australia, and South America, becoming an important fruit species.
  1. Growing Environment:
    1. Kumquats thrive in warm, humid climates and are fairly cold-resistant. The ideal temperature for growth is between 15-30°C.
    2. They require full sunlight and well-drained soil. While they are adaptable to various soil types, loose, fertile, and well-drained sandy loam is optimal.
    3. Kumquats are best suited for low-altitude areas, typically below 500 meters, but they can also be grown in higher altitudes in some cases.
  1. Cultivation Management:
    1. Kumquats are sunlight-loving plants, so it’s essential to choose a location with ample sunlight.
    2. Regular watering is required to keep the soil moist, but water should not stagnate.
    3. Apply moderate amounts of organic fertilizer to promote healthy growth and fruit development.
