Chinese Citrus trees grown as ornamental container plants may take up to five years to produce fruit. Container-grown ornamental orange trees are usually the dwarf varieties which grow to a height of 4 to 10 feet. Limited root space has the effect of stunting tree growth even if it is a standard variety. Chinese Citrus trees are damaged at frost temperature but can be grown in wintertime indoors.
Max reachable height: 4 to 10 feet.
Difficulty to grow: Easy
Planting and care Sunlight: Provide direct sunlight for at least several hours daily. Move the plants outdoors for a few hours daily in the spring, increasing the time outdoors until the tree can stay outdoors for the summer. Bring the tree indoors in the fall.
Soil: A mixture of 1 part each potting soil, organic compost and per-lite or vermiculite.
Water: Water the tree as needed to keep the soil moist but not wet. Allow the top inch of soil to dry out before watering.
Temperature: Capable of withstanding temperatures as low as 20 degrees Fahrenheit, but prefers warmer temperatures of at least 55 to 70 degrees Fahrenheit.
Fertilizer: Fertilize your calamondin orange with a citrus formula or a slow-release formula specifically for acid loving plants during the growing season. Dilute the fertilizer to half the recommended strength during the winter months.
