What You'll Learn
Grapefruit grow in the Northern Territory
Grapefruit can be grown in home gardens in the Northern Territory (NT) of Australia. The citrus crop thrives in the warm to hot and dry summers of the region and is mostly grown in the Darwin and Katherine areas of the NT. The grapefruit tree is evergreen and small, with white, large, and fragrant flowers. The fruit has a yellow rind and yellow flesh, although red-fleshed varieties are also grown successfully in the NT.
The grapefruit tree is native to Barbados and is believed to be a hybrid of the sweet orange and pummelo. It is a fast-growing tree that prefers low or moderate rainfall with cool winters. In the NT, grapefruit trees need to be pruned from a young age to ensure good branch structure. They should be watered in the Dry Season and fertilised with nitrogen at the right time. Grafted trees are preferred over seedlings and should be bought from accredited nurseries.
The Ray and Henderson varieties of grapefruit are the most productive in the NT, although the Rio and Flame varieties have better colour. The Rio Red variety, in particular, grows well in the NT and is known for its red flesh. Other varieties that grow well in the NT include the Flame and Star Ruby, which have red flesh, and the white-fleshed Marsh variety, which tends to be less acidic and more pleasant to eat when grown in tropical conditions.
When growing grapefruit in the NT, it is important to note that mature fruit should not be left on the tree when ripe, as it will develop puffy skin, hollow centres, and off flavours. Grapefruit will keep for three months if stored at 10 degrees Celsius. They are traditionally eaten at breakfast and are also used to flavour and garnish food.

Well-drained soil and full sun are ideal conditions
Grapefruit trees can grow up to 4 metres or more in height and width, so they require plenty of space. They thrive in well-drained soil and full sun. If your soil is clay-based, you can improve its structure by adding gypsum and forking it in. You can also raise the level of the bed with free-draining garden soil. To check if your soil needs work, dig a hole and pour a bucket of water into it. If the water takes more than 30 minutes to disappear, you will need to improve the drainage.
Grapefruit trees grow well in most parts of Australia, except for mountain areas. They originated in the West Indies and require high heat, so choose the warmest position possible in your garden. If you're short on sunny spots, you can grow grapefruit in pots that can be moved to take advantage of changing sunlight patterns.
In the Northern Territory, grapefruit trees need to be pruned from a young age to ensure a good branch structure. They should be watered in the dry season and fertilised with nitrogen. Backyard grapefruit trees in the Darwin and Katherine regions usually fruit from mid-February to the end of April, while those in Alice Springs fruit from early April to the end of May.
When planting grapefruit trees, dig a hole twice as wide as the root ball and to the same depth. Remove the shrub from its container, gently tease the roots, and cut away any circled or tangled roots. Form a raised or doughnut-shaped ring of soil around the outer edge of the plant's root zone to help retain water. Keep the soil moist for several weeks while the new plant establishes. Water deeply once or twice a week, depending on the weather.

When growing grapefruit, it is important to select a sunny spot with well-drained soil. If your soil is clay-based, you can improve its structure by adding gypsum and forking it in well. In such cases, it is also recommended to raise the level of the bed and add Yates Dynamic Lifter Soil Improver to enhance drainage. For potted grapefruit, choose a dwarf variety and a good-quality mix, such as Yates Potting Mix with Dynamic Lifter.
To use Yates Dynamic Lifter, simply mix it into the soil prior to planting and then reapply as needed during the growing season. For flowers and vegetable beds, mix 100g per square metre into the soil. For native shrubs, azaleas, rhododendrons, and acid-loving plants, apply 50g to 100g per square metre, starting 15cm from the plant trunk. Fruit trees require a higher amount, with a dosage of 500g for each year of the tree's age (up to 5kg) applied once in spring and again in autumn.
By following these guidelines and using Yates Dynamic Lifter Soil Improver & Plant Fertiliser, you can create the ideal growing environment for grapefruit trees in Australia, ensuring healthy and vigorous growth.

Backyard trees may flower and fruit all year
Grapefruit trees can make a wonderful addition to your backyard, providing shade and an abundance of fruit. These evergreen trees can grow to impressive sizes, with heights of 4 metres or more, but regular pruning will keep them to a manageable size. When choosing a spot for your grapefruit tree, select the warmest position possible, as this fruit has high heat requirements. A sunny spot with well-drained soil is ideal. If your soil is clay-based, consider adding gypsum and forking it in to improve the structure.
In terms of fertilisation, it is recommended to feed your grapefruit tree with a suitable fertiliser three times a year: in early spring, summer, and autumn. When the tree starts to produce fruit, usually after its second year, switch to a weekly feed of citrus-specific liquid plant food. For potted trees, fertilise every six to eight weeks, alternating between complete citrus food and a dynamic lifter, or use a 3-4 month osmocote applied in spring and early summer. Water well before and after fertilising, and keep the soil moist for several weeks while the new plant establishes itself.
Grapefruit trees are self-fertile, so you only need one tree to produce fruit. However, it's important to note that grapefruit trees may take a few years to bear fruit. The fruit is ready to pick when it is firm and heavy, with smooth, bright yellow or red skin, depending on the variety. Some common varieties grown in Australia include the Marsh, Thompson, Wheeny, and Texan Pink. The Marsh variety has yellow flesh and is known for its strong growth and consistent fruiting. The Wheeny, which originated in NSW, has large yellow fruit with a bitter, acidic flavour. It is one of the quickest and strongest-growing citrus varieties.
With proper care and attention, your backyard grapefruit tree will flourish and provide you with an abundance of delicious and nutritious fruit.
