Date palms as an ornamental are very popular and grown over a wide geographical area throughout Australia. Some of the locations we have seen them include: Adelaide, Melbourne, Sydney, Brisbane, Cairns, Perth, Alice Springs and many outback towns. The date palm is widely adaptable and makes a particularly handsome and hardy ornamental.
The ideal climate for the production of premium table dates is one which has a long, hot dry summer. The hotter the climate is, the more varieties that will successfully ripen. We have concentrated our varietal selections on early ripening varieties such as Khadrawy and Medjool. Also Barhee because it can be harvested when still semi-ripe (khalaal).
Districts which have excessive rain or high humidity at the fruit ripening stage will generally encounter fruit spoilage and yield loss problems. Some varieties are more prone to rain damage than others. In some moist climates in the northern hemisphere, dates are harvested at the khalaal stage and artificially ripened to avoid moisture damage from the opening season rains.
Brian Reilly who enjoyed a lengthy career as a forecaster with the Bureau of Meteorology has prepared Heat Unit and Summer Rainfall charts for the Date-feasible regions of Australia. These provide basic guidance on the climatic suitability of existing sites and give an indication of where to look for start-up locations.
These do not guarantee areas or districts nor do they exclude other areas but are designed as a first glance guide only. We suggest anyone considering commercial production undertake their own independent studies.

Below are some photos of a high water table in a customer’s horticultural block. This regionally high water table has been created from decades of irrigation throughout a horticultural district. The water table is undesirable for his mandarin trees due to the poor drainage and reduced root-zone depth.
This is ideal for date palms. We are anticipating these palms will in coming years, produce good crops while requiring little irrigation. We expect the palms will help lower the water table and create better drainage for the mandarins.
