The Philippines is the only major producer of calamansi. It ranks as the fourth most widely-grown fruit crop in the Philippines, after banana, mango, and pineapple. It is primarily grown for its juice extracts which are exported to the United States, Japan, South Korea, Canada, and Hong Kong, among others.<ref name="Rodeo"/>

The Philippines exports between 160,000 and 190,000 [[metric ton]]s of calamansi juice each year. Major production centers include the [[Southwestern Tagalog Region]], [[Central Luzon]], and the [[Zamboanga Peninsula]].<ref name="Rodeo">{{cite book |last1=Rodeo |first1=Arlan James D. |chapter=The Philippine Fruit Industry: An Overview |date=2016 |publisher=Jiangxi Academy of Agricultural Sciences |title=International Training Workshop on Cultivation Techniques for Fruit Trees, 10-24 October 2016 |url=https://www.researchgate.net/publication/311067359}}</ref> Its cultivation has spread from the Philippines throughout Southeast Asia, India, Hawaii, the West Indies, and Central and North America, though only on a small scale.<ref name=hort>Morton, J. 1987.

In sub-tropical and parts of warm temperate North America, × ''Citrofortunella microcarpa'' is grown primarily as an [[ornamental plant]] in gardens, and in [[flower pot|pots]] and [[container garden]]s on [[Terrace (building)|terraces]] and [[patio]]s. The plant is especially attractive when the fruits are present.<ref>{{Cite web |title=Citrus ID: Fact Sheet: Calamondin |url=https://idtools.org/id/citrus/citrusid/factsheet.php?name=Calamondin |access-date=2022-06-01 |website=idtools.org}}</ref>

The plant is sensitive to prolonged and/or extreme cold and is therefore limited outdoors to tropical, sub-tropical and the warmer parts of warm temperate climates, such as the coastal plain of the southeastern United States (USDA zones 8b - 11), parts of California, southern Arizona, southern Texas, and Hawaii. Potted plants are brought into a [[greenhouse]], conservatory, or indoors as a [[houseplant]] during the winter periods in regions with cooler climates.<ref>{{cite book | author = Mabberley, D.J. | date = 1987 | title = The Plant Book.
