History of the Kakadu Plum Tree
Kakadu plum trees, also known as billygoat plums or salty plums, are a type of flowering plant that produces a distinctive fruit. This plum tree originated in the tropical woodlands of the northwestern and eastern Arnhem Land areas of Australia. They’re also native to Queensland and the Northern Territory.
Initially, the plum was utilized for its health benefits. In fact, in traditional medicine, people used these fruits to manage cold and flu symptoms as well as headaches. Additionally, the bark was used as a soothing balm and an antiseptic.
After noting the popularity of kakadu plums, Australians started to commercially harvest this fruit in the late 1990s. Particularly, they use these plums for hair, food, and skin products.
The plum did gain worldwide recognition since this fruit has the highest level of vitamin C than any other fruit. In fact, one kakadu plum has more than 50 times the amount of vitamin C as an orange.
Tree / Fruit Characteristics
The kakadu plum tree is a smaller or medium-sized tree with rounded leaves. It’s about 13 to 32 feet in height.
Initially, the fruit tree grows cream-colored flowers that grow in clusters toward the ends of the branches, usually between August and October.
From March to June of the following year, green fruits appear that usually get between .1 to .2 of an ounce in weight. They’re usually between one-half inch and one inch in length. Often, they’re similar in size to a cherry. It tends to get yellow or purple later in the season.
Ideally, these plums thrive best in tropical weather. Zones eight and nine are most suited for this particular plum tree. In these areas, the plum tree can receive the sunshine it needs.
You may be able to grow these plums in other zones as long as you get sunlight and minimal frost since they prefer warm weather above freezing temperatures.
Size and Spacing
You don’t necessarily need more than one kakadu plum tree. However, since these trees are known to get wide, you want to plant them far apart from one another if you do have more than one. This ensures they get enough sunlight without blocking out the sun to the other one.
The kakadu plum is a self-pollinator. That means it only requires one plant to pollinate, which makes it ideal if you only want one plant or have limited space in your yard. That means, one plant has both male and female parts. The pollen from an anther of one flowered is transferred to the stigma of either the same flower or another flower on the plant.
Kakadu Plum Tree Care
The kakadu is quite a temperamental plant that requires a balance of sun and water. It also needs regular pruning to ensure the plant continues to thrive and doesn’t acquire a widespread disease.
This particular plum tree is partial to the sun. Generally, you want to plant it in a place that gets ample sun all day. It needs to be spaced out from other plum trees and trees in general because it likes between 80 and 100 percent of the sun.
Watering The Kakadu Plum Tree
It needs a moderate amount of water. It ultimately depends on where you live how often and how much you’ll need to water it. Areas that are known to get less rainfall won’t need to water it as much as a plant that doesn’t get much rain.

However, you’re not pruning too early that it affects the tree flowering and developing fruit.
When you prune the tree, you should remove branches that appear to have any type of disease. You want to stop the disease from spreading, so it may require treatment after you rid the tree of its unhealthy branches. You also want to remove dead and broken branches. Keep in mind that a broken branch can allow a disease to enter and infect the plant.
