Aniseed Boronia is suited to dense, mixed gardens and needs some protection from intense afternoon sun or strong winds. For best results, place it were it receives afternoon shade and is screened from southwesterly winds.
Aniseed Boronia Aniseed boronia has fragrant flowers and is well suited to locating near paths and outdoor living spaces
Aniseed Boronia is ideally placed at the front of your garden bed.
When to Plant and Watering
Plant young seedlings in Djeran (mid-Autumn) prior to the Makuru rains (Winter). Avoid planting in the hottest times of the year.
Seedlings should be watered twice a week over their first summer in the garden. It is important to ensure water penetrates down into the root-zone.
We recommend using a soil wetting agent as Perth soils are often ‘water repellent’, or do not absorb water effectively.
A layer of composted, coarse mulch can help in getting your garden started. It will help by reducing water loss and suppressing the growth of weeds.
Aniseed Boronia generally have low water requirements but will benefit from deep-watering in summer.
Deep-water by applying about 3L per plant once a fortnight, increasing to weekly intervals during heatwaves.
For best results, use a wetting agent to ensure water penetrates the soil effectively.
Aniseed Boronia should be grouped with other plants which benefit from occasional summer watering.
Feeding and Soil Care
Aniseed Boronia don’t need fertiliser because they are adapted to grow in our local soils, which are typically low in nutrients.
Plants will benefit from adding some vegetable-based compost (avoid those with manure) into the soil at planting.
As your garden develops, practice ‘cut and drop’ when you prune your plants. The leaf and branch material that falls to the ground slowly breaks down over time, releasing nutrients to help your garden to grow.
How to Prune
Aniseed Boronia can be maintained to their desired shape with regular tip-pruning.
Pluck the top couple of centimetres of the plant’s growing tips by hand once or twice a year.
If necessary use pruning shears, but avoid cutting down to the hard woody stems.
