Growing Berries In Australia: A Comprehensive Guide

how to grow berries in australia

Berries are a delicious treat, especially when they're freshly picked from your own garden. They're also easy and rewarding to grow, even in a tiny garden or on a balcony. Popular berries to grow in Australia include strawberries, blueberries, raspberries, blackberries, boysenberries, and thornless blackberries. Cane berries, such as raspberries, blackberries, and boysenberries, are unique in that the crown of each plant in the ground is perennial. They grow well in rich, loamy, and freely draining soil with a neutral to slightly acidic pH of 7-6.5. Most berry plants thrive in full sun, but some, like blueberries, prefer a mix of warm days and cool nights.

Growing strawberries

Strawberries are a delicious treat, especially when picked fresh from your own garden. They can be grown in most places with a sunny spot, including in containers, raised vegetable beds, vertical gardens, and hanging baskets. Here are some tips for growing strawberries:

Soil and Planting

Strawberries are shallow-rooted and will dry out quickly in the wind, especially in hanging baskets. They do well in slightly raised beds (about 15-20 cm high) or pots, with 20-30 cm between plants to allow for air circulation and growth. Prepare the beds in advance to ensure deep, rich, humus-filled soil. Two weeks before planting, water the soil with seaweed tea or liquid seaweed, which helps the plant settle in. When planting, use good-quality potting mix or compost-rich soil, mounded to improve drainage.

Maintenance

Mulch well with straw or pine needles to keep fruit clean and prevent fungal diseases and weed invasion. Water well and feed regularly. Remove runners (new branching growth) to keep plants compact and productive. If your plants are small, remove early flowers or immature fruits to encourage the plant to produce fresh growth and higher yields when fully developed.

Pests and Diseases

Strawberries are susceptible to pests and diseases, including snails, slugs, and bugs such as harlequin bugs and green vegetable bugs. Protect your strawberries from these pests by setting up traps and doing regular night-time checks. Birds and other wildlife may also be a problem, so net your strawberries in summer and autumn using bird and animal-safe netting, or cover with a fruit cage or protective cage.

Growing blueberries

Blueberries are a relatively easy plant to grow, but many people struggle with them. They are an ideal fruiting plant for the home garden and can thrive in containers, so even the smallest garden can enjoy fresh, home-grown blueberries.

Blueberries require good drainage and acidic soil with a pH of between 4 and 5.5. You can test your soil's pH level with a test kit or by sending it to a laboratory. If your soil is not acidic enough, you can lower the pH by adding powdered sulphur or using spent coffee grounds and pine needles.

When planting blueberries in the ground, dig a hole about twice the size of the pot and fill with acidic organic matter like composted pine needles or soil improver. Make sure you don't plant the bush any deeper than it grew in the pot. If growing in a container, choose a pot at least 30cm in diameter with good drainage holes and fill with an acidic potting mix.

Blueberries require regular watering throughout the growing season and do not tolerate drought. They also benefit from fertiliser, but it is important not to over-fertilise. Mulch is ideal for blueberries as it protects the roots and provides organic matter.

There are three main types of blueberry in Australia: Northern Highbush, Southern Highbush, and Rabbiteye. Northern Highbush varieties demand an acidic, well-drained soil with high levels of organic matter and a longer period of winter chilling. Southern Highbush varieties grow well in coastal and warm inland regions, while Rabbiteye can cope with moderately cool climates.

Growing blackberries

Blackberries are sprawling, semi-deciduous shrubs with arching, prickly or thornless canes that produce edible berries from late spring to early autumn. They are quite vigorous growers and can be highly invasive, so ensure there is plenty of room in the garden. Thornless blackberries are easier to pick and won't spread as rampantly as wild blackberries, but they still produce lots of tasty fruit.

Blackberries prefer a cool climate, but there are hybrids, such as youngberry and loganberry, that will grow in warmer areas. They need full sun and regular feeding, and prefer a slightly acidic soil with a pH between 5.5 and 6.5. Compost and manure will help increase the acidity of the soil, but powdered sulphur can be added if the pH is still too high.

Winter is a good time to plant blackberries, as this is when packaged blackberry canes appear in shops. Before planting, clear away weeds and improve the soil by mixing in some fertiliser. Set out the dormant canes 1.5m apart, in rows 2m apart. If using a trellis or structure for the blackberries to grow on, make sure this is in place at planting time. Canes can be tied together loosely with twine and trained to grow on a trellis, which makes pruning and harvesting more manageable.

Blackberries should be planted in rows running north to south so the canes receive plenty of sunshine. Fruit can get spoilt from extreme heat and sunshine, so cover with shade cloth to protect it. Water blackberries regularly to keep the soil moist and feed with organic-based pelletised plant food in early spring and late summer.

Growing raspberries

Raspberries are easy to grow and can provide an abundance of fruit in summer and autumn. They are best eaten fresh from the garden for optimal flavour and nutrition. There are two commonly grown types of raspberry: summer-fruiting and autumn-fruiting. Summer-fruiting raspberries produce fruit on two-year-old canes (floricanes), while autumn-fruiting raspberries fruit on the current season's growth (primocanes).

Raspberries should be planted in full sun in single rows with spacings of 30 cm. You can improve the soil prior to planting with aged compost and manure. It is recommended to top-dress the soil annually with compost to maintain soil fertility. You can also apply a little blood and bone or dynamic lifter in spring to encourage optimal spring growth.

Raspberries like to grow in slightly acidic to neutral soil, with a pH between 6.5 and 6.8. They thrive in rich soil, so it is important to enrich the soil with plenty of rotted manure, compost, and organic matter. Feed your raspberry plants once every autumn and spring with a soil improver and plant fertiliser. When flowering and fruiting, feed weekly with a strawberry and berry fruit liquid plant food to help promote fruit production.

To support the growth of your raspberries, set up two parallel wires above the plants at 90 cm and 1.8 m high. As the canes grow, bundle them together loosely with twine and train them to grow over the wires. It is important to net your crop, especially after flowering, to prevent birds from stealing your harvest. A permanent structure allows for easy netting, but a temporary frame can also be set up using hardwood stakes.

Raspberries are typically ready for harvest when the fruit is ripe and well-coloured. The receptacle or 'stem' attached to the fruit should easily come away from the plant. It is important to note that raspberries may be attacked by pests such as fruit flies, birds, and bugs like Scale and Mealy Bug. To protect your crop, you can net your plants in summer and autumn using bird and animal-safe netting or cover them with a fruit cage.

Protecting berries from pests and wildlife

Another bird-repelling method is to use chemical repellents, but these may only be effective for a few days. Commercial growers also use sugar syrup on blueberry shrubs, but this can attract Japanese beetles and yellow jackets. Audio scare tactics, such as cannons, gunfire, firecrackers, taped noises, or radios, can be employed, but birds may get used to the sounds over time. Combining audio and visual scare tactics, such as an owl model that shrieks at intervals, can be more effective.

Slugs and snails are also common pests for strawberries and can be controlled by regularly picking them off by hand, looking under and through the plant, and checking after rain. Iron-based snail bait is another option that is safe for pets and wildlife. Surround the plant with organic mulch, such as lucerne straw or pine needles, to keep the berries off the soil and prevent fungal diseases.

For other types of berries, such as blackberries, boysenberries, and raspberries, growing them along a fence or setting up a sturdy post-and-wire system can help provide support and protection. Keep an eye out for bugs like harlequin bugs and green vegetable bugs, which may attack new growth, flowers, or developing fruit. Fruit flies can also be a problem for soft fruits like raspberries.
