Few plants can rival the enchanting scent of Boronia, a delightful Australian shrub with aromatic foliage and fragrant flowers. Though sometimes considered demanding, you can easily enjoy Boronia's beauty and charm in your garden or home with the right knowledge.
Prepare Soil
Garden: Boronias thrive in sheltered spots with free-draining, slightly acidic soil. Avoid windy areas and ensure the soil retains moisture without becoming waterlogged. You can mimic Boronia's natural habitat by creating a sandy, acidic humus-rich soil. Add peat and leaf mulch to retain moisture without compromising drainage.
Pots: Perfect for container gardening, Boronias love a potting mix low in phosphorus, such as Oderings Shrub & Tub. For optimal growth, place them in bright, indirect light.
Feed
Garden and Pots: Use a slow-release, low-phosphorus fertiliser. Take care to avoid disturbing the roots when applying fertilisers or weeding.
Watering & Mulching
Watering: Keep soil consistently moist but never soggy, as Boronias detest "wet feet." Water deeply and regularly, particularly in dry spells.
Mulching: Apply a layer of leaf mulch around the base to conserve moisture and maintain a consistent soil temperature.
Protection
Avoid disturbing Boronia’s root system even when planting, as this can lead to plant death, especially in the Brown Boronia variety. When planting, cut away the pot or bag to minimise root disturbance. Mulch around the plant helps weed disturbance.
Pruning
Boronias respond well to pruning after flowering. Cut back by one-third or even half if necessary. Regularly harvesting fragrant stems for indoor use promotes healthier growth and prolongs the plant’s life.
Varieties to Consider

Garden Expert Tip
For the best results, plant Boronias where their fragrance can be enjoyed, and remember to water deeply and mulch well. A Boronia planted in the wrong spot is unlikely to survive transplantation—so choose carefully!
Bring Boronia's fragrance and beauty indoors by cutting fragrant stems or blooms. Their flowers last well in arrangements, making them perfect for filling your home with their delightful scent.
