How to grow Mexican Orange

Sunlight
Full sun to partial shade
Watering
Moderate while establishing; low thereafter
Soil
Well-drained, moderately fertile
Soil pH
Acid to alkaline

Planting

Plant in spring in a sheltered position out of cold drying winds, which scorch the evergreen foliage. It does well against a wall and copes with some shade, though flowering is better in sun.

Pruning

Prune straight after the main flush of flower, cutting back to a healthy bud or shoot. Removing a proportion of the older stems each year keeps it dense. It reshoots from old wood, so overgrown plants can be cut hard back in late spring.

Propagation

Semi-ripe cuttings in late summer root readily.

Pests and diseases

Generally trouble-free. Snow load and hard frost can split or brown branches; cut the damage out in spring and it usually recovers.

Value to wildlife

Scented white flowers attract bees, and the evergreen structure gives year-round cover for small birds.

Notes

It commonly gives a second, lighter flush of flower in late summer or autumn, particularly after a good prune in early summer. The foliage is aromatic when crushed, so it is worth siting near a path or door.
