Growing jojoba
For those in dry arid inland areas, growing jojoba can be a rewarding option. Jojoba is a hardy, drought-tolerant shrub prized for its oil-rich seeds that are used in skin and haircare products. Even though this is an arid plant with the right microclimate provided you can have success even outside of its preferred climatic zone.
Climate
Growing jojoba is best suited to hot, arid, desert-like climates such as inland QLD, Western NSW, SA and WA’s drier regions.
Temperature
Ideal temperatures 15–40°C. However, can tolerate light frost.
Soil
Prefers well-drained sandy or gravelly soils that are slightly alkaline with a pH of 7–8.5. If needed, improve drainage with gypsum and sand. If the soil is acidic, add dolomite. Jojoba does not tolerate waterlogging – root rot can be a real risk.
Water
Extremely drought-tolerant once established. During the first 1-2 years, regular watering is needed, however, once established, deep but infrequent irrigation is best.
Planting jojoba from seed
Seeds germinate best when fresh. Scarify lightly (nick the seed coat) to improve germination. Plant 2–3 cm deep in warm soil. Germination takes 2–6 weeks.
Note Jojoba is dioecious, meaning it has separate male and female plants.
Ratio 1 male for every 6–8 females. Plant several seeds to ensure both sexes
Pruning
No heavy pruning only light pruning helps shape the plant and improve airflow.
Fertilising
A light application of ActivGrow Fertiliser Pellets 4kg Pellets in spring.
Harvesting jojoba nuts
With patience, growing jojoba can provide a productive crop of nuts after 3–5 years, with full production reached at 8–10 years.
Preparing nuts
Harvested nuts require drying for 2/3 weeks to maximise oil content and then they can be cold pressed for oil as the liquid wax (oil) they produce is great for skin and haircare.
