Mexican orange

Mexican orange (Choisya arizonica 'Bluestone') should be watered once a week, making sure to water deeply. They should be given about 1 inch of water each time, though an occasional extra deep soak (1.5-2 inches) is beneficial in the hotter months and for those growing in containers. In the winter months, you should water less often, letting the soil dry out before giving it more water.

Mexican orange (Choisya arizonica 'Bluestone') plants prefer to have 4 to 6 hours of full sun each day. They can also tolerate some light shade during the hottest part of the day. But too much shade will result in fewer blooms, smaller foliage, and reduced plant vigor. For best results, it is important to ensure that Mexican orange plants get direct sun from mid-morning until mid-afternoon each day during the growing season.

Mexican orange (Choisya arizonica 'Bluestone') should be pruned once or twice per year - once in spring or summer, and an additional, more general time after flowering if desired. During the spring or summer, prune to shape and control the plant size, removing crossing branches, long straggly shoots, and leafless twigs to reveal the plant's form and encourage branch development. When pruning after flowering, prune to form a good rounded shape, reduce the size of the plant, and ensure that flowering shoots remain at the centre. In any pruning, ensure that strong shoots are left at the base of the plant and that thinning is concentrated at the very top of the plant. Be careful not to over-prune, as this may damage the health of the plant. When pruning Mexican orange, use sharp, clean pruning sheers and wear gloves to protect your hands.
