Carrot Cultivation In Australia: Where And How?

where do carrots grow in australia

Carrots are one of the most valuable vegetable exports from Australia, with Western Australia producing over 90% of the country's carrot exports. In 2004, carrots were Australia's fifth most valuable vegetable crop, and they are commonly grown in rotation with other crops such as potatoes, lettuce, and onions. They are grown on a wide range of soil types, although sandy soils are favoured, and they need at least six hours of sunshine a day. The best time to plant carrots in Australia is during spring, autumn, and winter, and they are usually grown from seeds sown directly into the soil.

Best time to plant

The best time to plant carrots in Australia is spring, autumn, and winter. However, it is important to avoid extreme cold and hot temperatures unless you are willing to provide extra care for your carrots. The growing period for carrots typically ranges from 14 to 24 weeks, depending on the location and time of year. In general, carrot seeds should be sown directly into the garden or into biodegradable pots for seedlings before being transplanted into the garden.

When planting carrots, it is important to create a trench about 2 cm deep and fill it halfway with a soil-sand mix or a seed-raising mix. After sprinkling the carrot seeds along the row, cover them lightly and press gently to ensure contact with the soil and seed. Water the seeds gently to avoid displacing them and cover the bed with straw mulch to retain moisture. Keep the bed damp until the seeds germinate, which typically takes about 2 to 3 weeks.

Carrot seeds prefer a soil temperature of 8°C to 30°C for optimal germination, which usually occurs within 14 to 21 days. However, germination may occur outside this temperature range, albeit at a slower rate. The ideal soil temperature for germination can be challenging to achieve, as it differs significantly from air temperature. Therefore, gardeners should be patient and not give up on their seeds, even if the expected germination window has passed.

To ensure healthy carrot growth, it is crucial to thin the seedlings when they reach a height of 5 cm, leaving about 3 cm between each seedling. This process may need to be repeated when the seedlings reach 12 to 15 cm in height, increasing the spacing to about 5 cm. While thinning may seem wasteful, the removed seedlings can be composted or fed to chickens, and the thinned carrots can even be eaten.

Carrots thrive in sandy soils with good drainage and should be kept moist but not overwatered to prevent root rot. They also benefit from companion planting with spring onions to deter pests like carrot flies and aphids. Additionally, an application of SeaMax Seaweed every fortnight can enhance the sweetness and overall health of your carrots. By following these planting and care guidelines, you can successfully grow carrots in Australia during the recommended seasons.

Soil type and preparation

Carrots can be grown in all climatic zones throughout Australia year-round. They require at least six hours of sunshine a day and well-drained soil. The soil should be soft, free from hard lumps, and have a pH of between 5.8 and 7.0.

Before planting, it is important to prepare the soil. Firstly, dig the soil to a depth of at least 30 cm. Break up the soil so that it is fine and even, removing any large clods, rocks, or debris that could affect the growth of the carrot. Carrots like to grow straight down, so it is important that there are no obstacles in their path. If your soil is heavy, you can add horticultural sand or river sand to the mixture to improve drainage and make it easier for the carrots to push through. You can also add some compost to the mixture.

Once the soil is prepared, create furrows or shallow trenches about 6-8mm deep and 10-30cm apart, depending on the variety of carrot. Space the seeds 3-5cm apart and cover them with a soil/sand mix. Water the seeds gently, being careful not to blast them out of the ground. Keep the bed damp until the seedlings emerge, which should take about 2-3 weeks.

When the seedlings are 5cm high, you will need to thin them out by pulling out the weaker or smaller ones and leaving about 3cm between each carrot. You will need to do this again when they reach 12-15cm, this time leaving about 5cm between each plant. Carrots require consistent moisture, so make sure to water them regularly, especially during dry periods.

Carrot varieties

Carrots are easy to grow and are suited to all Australian climates. They are commonly grown in rotation with other vegetable crops such as potatoes, lettuce, cauliflowers, broccoli, and onions. They can be grown on a wide range of soil types, although sandy soils are favoured because of better root quality and ease of harvesting. The growing period for a carrot crop ranges from 14 to 24 weeks, depending on location and time of year.

In Australia, prior to the 1950s, the main carrot variety grown was the Osborne Park Champion (also known as Champion Red Core). During the 1950s, a range of varieties were grown, including Red Core Chantenay, Imperator, Top Weight, and All Seasons. A selection of Osborne Park called Western Red established itself as the main variety in Australia by the 1970s due to its high yield and quality.

Western Red remained the most popular carrot variety until the introduction of hybrid Imperator varieties from America and hybrid Nantes varieties from Europe in the early 1990s. Most carrot varieties grown in Australia belong to one of the following four variety groups, distinguished by shape. Some new varieties, such as Mojo, are the result of combining characteristics from several variety groups via conventional plant breeding.

The 'All Seasons' carrot variety is a popular choice for gardeners in Australia. It prefers full sun and well-drained soil. This variety has a germination time of approximately 14-21 days when sown at a soil temperature of 10-30°C. It is important to note that soil temperature usually differs from air temperature. 'All Seasons' carrots can be grown in hot, dry summers, and winters can be warm or cool depending on the region.

Carrot seeds are widely available for purchase online in Australia and come in various colours and shapes depending on the cultivar type.

Harvesting

Carrots can be grown in all climatic zones throughout Australia and are commonly grown in rotation with other vegetable crops. They can be grown in pots or in the ground. The best time to plant carrots in Australia is spring, autumn, and winter. Avoid cold and hot extremes unless you are willing to give your carrots extra care.

Carrots can be harvested after about eight weeks. You can prolong your crop by only harvesting what you need when you need it. However, you will want to harvest all your carrots before the sugars turn to starch, which happens at about 16 to 18 weeks.

Carrots grown in pots can be harvested by carefully tipping the pot on its side and pulling the carrots out by hand. Carrots grown in the ground can be harvested by hand or with a single-row harvester. Carrots can be difficult to pull out of the ground, so using a garden fork to loosen the surrounding soil can make this process easier. Carrots should be washed after harvesting.

Carrots are susceptible to carrot flies, which lay their eggs in young seedlings. The larvae eat and tunnel their way through the growing root. They can be deterred by using plenty of compost and some good companion plants, like spring onions, to act as decoys.

Carrot exports

Carrots have been the most valuable fresh vegetable export from Australia since 2002. In 2004/05, about 20% of Australian carrot production was exported fresh, with most of the remainder sold for domestic consumption. In 2006, Australian carrot exports of 66,000 tonnes were valued at $43.5 million.

Western Australia is the dominant carrot-producing state, accounting for 90%-94% of Australia's carrot exports by value. In 2012/13, Western Australia exported 64,430 tonnes of carrots worth $48 million free-on-board (FOB). Carrot exports from Western Australia reached a record high value of $48 million FOB in 2012/13, up slightly from the past three years and 42% higher than in 2007/08. The main markets for Western Australian carrot exports are the United Arab Emirates (UAE), Singapore, Malaysia, Saudi Arabia, Qatar, and Bahrain.

In 2020, Australian carrot exports increased by more than 7% in volume and value, becoming a $100 million industry. The world's appetite for Australian carrots skyrocketed during the global pandemic. More than 110,000 tonnes of carrots were exported in 2020, with the majority sent to Asia and the Middle East. The main competitor for Western Australia's carrot exports is China, which dominates many of the same markets. However, Western Australian exporters focus on quality, food safety, and reliability to compete with China's lower production and freight costs.
