What You'll Learn
Date palms can be grown from offshoots or suckers
Date palms are easily propagated via suckers or offshoots, which generate from the base of existing palms. Offshoots are genetically identical to the parent palm and are therefore reliable in the characteristics displayed from the parent palm. They are clones of the parent plant, and will save you money on a new plant.
There are two types of offshoots: the lower and older ones, and the upper and younger ones. It is believed that low offshoots are more active physiologically than high ones and probably grow faster. The high offshoots have fewer carbohydrates than low offshoots, resulting in low root production and a low survival rate.
To promote rooting, the base of the offshoot should be in contact with moist soil for at least twelve months before removal. To remove an offshoot, first, irrigate several days before cutting. Then, dig away the soil from the offshoot using a sharp, straight-bladed shovel. A ball of earth, 5 to 8 cm thick, must be left attached to the roots of the offshoot, with the connection exposed on each side. The cut surfaces of both the offshoot and the mother palm should be covered with a copper sulphate product to avoid infection by Diplodia and other parasites.
To plant an offshoot, either plant it directly into its permanent garden location or in a container filled with palm soil. Gently firm the soil around it, just covering its roots. Keep the soil evenly moist, but make sure it doesn’t remain soggy. Keep the new tree out of harsh sunlight until its roots take hold.

The date industry in Australia has high export potential
Date palms are cultivated for their sweet fruit, dates, which are naturally wind-pollinated. Date palms can be grown from offshoots or suckers, which are genetically identical to the parent palm. Phoenix dactylifera, commonly known as the date palm, is cultivated in northern Africa, the Middle East, Australia, and South Asia. Date palms can grow to be 60-110 feet tall and can live for over 100 years. They are slow-growing plants that can take 4 to 8 years to bear fruit and start producing viable yields between 7 and 10 years.
In Australia, the date industry is emerging, with growers seeing high export potential. The country's arid climate and increasing temperatures due to global warming make it suitable for growing date palms, which thrive in hot and dry conditions. However, date palms require a significant amount of water to fruit well, so sustainable water sources are essential.
Growers in Australia face challenges such as low awareness of certain date varieties like Barhi and the need for more research funding to improve productivity. An association or representative body is desired to lobby the government for research priorities and collaborate with agricultural departments. Despite these challenges, the potential for the date industry in Australia is promising, with growers like Steve Brauer and Mark Hampel harvesting high-quality dates and exploring export opportunities.
The date palm is a resilient crop, with the ability to withstand salty sea breezes and some salinity in their irrigation water. They are a symbol of ancient productivity, often associated with desert oases. While they may be a slow return on investment, once fully matured, they can produce abundant yields. Additionally, date palms have multiple uses, including the production of palm sugar, palm wine, and spirits from their sap.
In conclusion, the date industry in Australia holds high export potential due to its favourable climate, resilient nature of date palms, and the ongoing efforts of growers to improve cultivation techniques. With the right support and research, the industry can overcome its challenges and establish Australia as a significant exporter of dates.

Date palms are hand-pollinated in commercial orchards
Date palms are dioecious, meaning they have separate male and female plants. Male date palms produce feathery flowers, while female flowers are more pronounced with longer individual strands that eventually develop into dates. In natural conditions, date palms are wind-pollinated, requiring an equal number of male and female plants. However, in commercial orchards, date palms are typically hand-pollinated to ensure successful fruit production.
Hand-pollination in date palm orchards is a common practice due to the slow growth and maturation rate of these trees. Date palms can take up to 15 years to reach full maturity, and they bear fruit between 4 to 8 years after planting. By hand-pollinating the female flowers with male pollen, growers can optimize fruit production and ensure a more consistent yield. This practice is especially important considering the significant time and resource investment required for date palms to reach their productive stage.
The process of hand-pollination in date palm orchards involves skilled labourers who climb up ladders or use specialized climbing tools to reach the flowers. In some regions, such as Iraq, a tool called "تبلية" (tablīyah) in Arabic is used by the pollinator to climb the tree, keeping them securely attached to the trunk. This method ensures that male pollen can be directly applied to the female flowers, increasing the chances of successful pollination and fruit development.
The male pollen used for hand-pollination can be sourced from local markets, as some growers may not maintain male plants in their orchards. A single male palm can provide enough pollen for approximately 25 female palms, making it efficient for commercial growers to purchase or acquire male flowers during the pollination season. This practice also allows growers to select compatible male and female varieties, enhancing the likelihood of successful fruit production.
Hand-pollination in date palm orchards is a labour-intensive process that requires careful timing and skilled workers. It is a critical step in the cultivation of dates, ensuring that the potential of the date palm industry in Australia is realized. With the challenges posed by climate change and the need for sustainable water sources, the careful management of date palm orchards through hand-pollination can contribute to the success and growth of this emerging industry in Australia.

The Canary Island Date Palm can be grown anywhere in Australia
The Canary Island Date Palm, or Phoenix canariensis, is a variety of date palm that can be grown anywhere in Australia. This variety of date palm has a robust trunk and a thick, dense canopy of leaves with very long spines at the base. While it does not reproduce via suckers or offshoots, it often has a carpet of germinating palms at the base of the tree. The Canary Island Date Palm is commonly used as an ornamental palm throughout Australia.
The Canary Island Date Palm is well-suited to the Australian climate as it tolerates heat and drought and can thrive in arid conditions. It also copes with salty sea breezes and some salinity in its irrigation water, as long as the drainage is good. This makes it suitable for Australia's coastal subtropics and wet tropics regions.
However, dates from the Canary Island Date Palm are tiny, only about the size of a small pea, and are not commercially viable. The fruit is also often ruined by fungi in summer. Despite this, the tree is a reliable source of famine food and can be grown even in places like Hobart, where other varieties of date palms may not thrive due to the cooler temperate climate.
The Canary Island Date Palm is just one of the many varieties of date palms that can be grown in Australia. Other varieties grown in Australia include Barhi, Bajool, Brown Barhi, Deglet Noor, Thoory, Khadrawy, Zahidis, and Bou Fergus. The potential of Australia's date industry is just starting to be recognized, and growers are looking to expand their export markets.
