Characteristics and uses:
The Calamondin Orange is commonly used as an ornamental plant, for its beautiful, exquisitely fragranced in spring and summer, white flowers. It also produces edible fruits, sour tasting, used to flavour dishes or in jams.
This citrus is one of the rarest which can be grown indoors, hence its name of indoor orange tree. In that case, it can produce flowers and fruits all year round, as long as it benefits from a good amount of sunshine and regular cares.
The Calamondin Orange has to be protected from cold in winter (pot and foliage), as it does not withstands temperatures that fall below 5°C.
In the coldest areas, shelter your Calamondin in a conservatory, or a non-heated room during winter.

Looking after advice:
Watering: As Citruses do not like dryness it is important to water them regularly, but not abundantly. In summer, water every day if necessary, in winter water once or twice a week.
Fertilizer: From March to October, give it a suitable citrus fertilizer once a month.
Pruning: Prune regularly in the spring and in summer to encourage ramification and keep it in the wished-for shape.
