The scientific name for calamondin is Citrus mitis. This citrus tree grows to 6½ to 25 feet tall with erect, slender thorny branches. It grows 1½- to 3-inch-long, aromatic evergreen eaves that are glossy. Calamondin develops sweet, fragrant flowers with white petals. Calamondin produce fruit with an orange-red glossy skin. This fruit looks like miniature oranges that are edible as well as ornamental. Calamondin is winter hardy to a temperature of 20 degrees F. Calamondin can be grown in a container, but it is better placed in the ground outside.
Place the calamondin in an area of bright light for the best growth and fruit production. Plant in an area of full sunlight if planting outside. If indoors, a calamondin can tolerate medium light during the winter.
Keep the temperature between 70 and 90 degrees F during the summer if growing indoors. Calamondin does not grow well at temperatures below 55 degrees F.
Feed calamondin often throughout the year. Feed your calamondin at half strength of water-soluble fertilizer every five weeks during the winter. Add slow-release fertilizer to the soil around the calamondin in early spring. Feed at full strength of water-soluble fertilizer every month during the season of active growth.
Water a calamondin as needed since excess or lack of water will kill this tree. Let the surface dry out to the depth of 1 inch before watering.
Wipe off the leaves with a damp sponge. Dusty leaves can become infected with mites and scales.
Clip the stems of the fruits as they become ripe and fully colored. A calamondin will continue to produce fruit throughout the year. The fruit is thin skinned and does not last very long after harvesting.
