Geraldton Wax Care
The secret to growing Geraldton Wax plants is mimic their natural conditions, sun, good drainage and neglect.
In nature they grow in poor sandy soils and do not need lots of fertilizer and rarely require watering.
Drainage is age most important aspect, as in wet soils they will quickly die as they are susceptible to root diseases. In areas where soils are naturally wet, try raising the level of the garden bed and planting Geraldton Wax on the raised section.
Chamelaucium grow well if planted in late winter to spring, they will require water through the first summer, once established, little to no water is required except in extended very dry periods.
If you are going to use a fertiliser, make sure that is low phosphate and use it sparingly.
One of the main problems is lack of sun, you will be better to plant in good sun than trying to treat then for the problems which tends to develop in shade.
Use Chamelaucium as a feature plant in the garden, as a low hedge or grow in containers. Also widely grown for cut flowers. When in flower this is a great plant for attracting birds, butterflies and bees to the garden.
These are a tallish plant, reaching 2 – 2.5 metres, they look great with Westringea and Correa, and can be used with many other native plants.
They can also be used with Salvias, Santolina and Lavenders..

In the home garden they are often kept pruned to form a shaped bush. A well drained soil and a sunny position will suit best.
You can also deadhead after flowering, just make sure that you do not prune back into old wood with no green growth on it.
