Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Citrus aurantium Common Name: Bitter orange Family: Rutaceae Author: L. Known Hazards: None known Mature Height: 9 Mature Width: 6 Habitat: Original habitat is obscure, possibly a back cross involving C. maxima X C. reticulata[200].
Cultivation Notes: Prefers a moderately heavy loam with a generous amount of compost and sand added and a very sunny position[1, 200]. Prefers a pH between 5 and 6[200]. Tolerates a pH in the range 4.8 to 8.3. Plants are intolerant of water logging[200].
Dormant plants can withstand temperatures down to about -6°c so long as this is preceded by cool weather in order to harden off the plant[200]. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K]. A tree grown outdoors on the coast at Salcombe in Devon lived for over 200 years[166].
The bitter orange is often grown for its edible fruit in warm temperate and tropical zones, there are many named varieties[183]. In Britain it can be grown in a pot that is placed outdoors in the summer and brought into a greenhouse during the winter[3, 200].
Plants dislike root disturbance and so should be placed into their permanent positions when young. If growing them in pots, great care must be exercised when potting them on into larger containers[238].
