Growing strawberries, blueberries, raspberries, mulberries

It is one of life’s simple pleasures to walk about in your garden in the warmer months and notice rich, juicy berries ready for picking. For most, the temptation is too great, and they are consumed immediately.


Growing Strawberries

There’s nothing better than the sweet flavour of home-grown strawberries! Loved by children and adults alike, it’s little wonder this easy-to-grow groundcover is among the most popular food crops in Australian home gardens. With its pretty white or pale pink flowers and familiar red berries which curiously bear their seeds on the outside, strawberries will crop throughout spring and summer with many varieties continuing through autumn.

New strawberry plants are best planted everywhere outside the tropics in June and July. (Tropical gardeners might prefer to put them in earlier, say from March to May to give them the longest growing season). Give strawberries a sunny position and improve the soil by digging in plenty of 5IN1 Organic Fertiliser before planting. Good drainage is essential, so build garden beds if your soil is heavy clay. Strawberries are also ideal for growing in pots, planters, or hanging baskets on a sunny balcony or courtyard.

Maintain a good layer of mulch over the soil. This will conserve moisture but keep fruit in good condition by preventing it from touching the ground. Strawberries produce runners which makes them easy to propagate. It is recommended that strawberry plants be removed, thinned, and the runners replanted every few years to ensure good crops and avoid overcrowding. Birds love strawberries as much as we do, so protect them with netting or place wire cages over your plants to protect your crop.


Growing Raspberries

Raspberries are generally available in garden retailers to plant in winter and depending on the variety, flower and fruit at different times from late spring to late Autumn.

The raspberry plant is a suckering shrub with cane-like stems that can grow up to 2 metres tall. Plant in a sunny spot as a hedge or in rows as a garden bed divider supported by a trellis or posts. Raspberries grow best in cooler climates. Certain varieties are available for subtropics but mainly the Australian native raspberries will grow in Queensland. Subtropic varieties. Raspberries grow well in well-drained and rich, well-composted soil, so before planting, dig into the soil 5IN1 Organic Fertiliser. They have shallow roots, so protect them by applying mulch around them, but do not touch the base of the plant. Fertilise in spring when flowers appear with Searles Fruit & Citrus Food.

Raspberries take 4 to 6 weeks to fruit. Harvest when they turn their iconic red colour. Prune back heavily tired and old canes after fruiting for a bumper crop the following year and keep stems away from the ground.


Growing Mulberries

Mulberries will be forming on their trees soon. Unlike raspberries and boysenberries which prefer a cool climate, mulberries are hardy in most parts of Australia. They generally grow as tall as a tree, but you can prune them to remain in a shrub. Dwarf varieties suitable for pots and small gardens are available in garden centres.

Mulberry trees love a sunny position with lots of room to grow. Plant them in a well drained, compost enriched, slightly acidic soil. Mulch well around the roots and fertilise with Searles Fruit & Citrus Food in early spring. Beware the ripe fruit stains and when the birds have a feed they make a big mess, so plant in a space away from driveways and patios. The mulberry tree produces fruit on new growth so they perform well if pruned to desired height that is easy for picking. They are fast growers so they will bounce back very quickly. Prune in late autumn after fruiting has finished. 

Mulberry trees are deciduous in winter with new leaves appearing in spring. The red fruit develop to their distinctive purple colour quickly in early spring in tropical and sub-tropics regions and more gradually in cooler regions giving these regions an extended harvest period. Harvest mulberries when they are fully ripened on the tree. Mulberries do not ripen after they are picked. They are also liable to spoil so promptly eat, cook with them or freeze them for later use.

If you’re looking for something more unusual, there’s a form with white berries (M. macroura ‘Shatoot’) which are sweeter and have a more subtle flavour.

Growing Blueberries

Due to the height, blueberry bushes grow, approx. 2m high, they are ideal for sunny spots in small gardens and container planting. Like azaleas, blueberry bushes are members of the Ericaceae family and flourish well in slightly acidic and well draining soil. If planting into the ground, mix Searles Azalea, Camellia & Gardenia Specialty Mix into the soil. This mix can also be used for planting in pots. Blueberry bushes have shallow roots with fine, fibrous, surface feeding roots, so after planting, add a top layer of mulch over the soil to protect them from extremes of weather. Plant blueberries preferably between late autumn and spring to give the plant time to establish its root system before flowering in spring. Generally, potted blueberries are available in garden centres all year round.

Blueberries love warm days and cool nights. Depending on where you live in Australia white belled shaped flowers start appearing on the bush in spring. Then a month or two later the flowers wither and the fruit appears. Generally, blueberry bushes flower earlier in Queensland and Northern NSW compared to their southern states. Harvest fruit when it turns to a deep dark blue colour and the fruit easily comes off the tree with a light twist with the hand. Blueberry bush will flower at different times during its flowering season, so you should have a healthy supply of berries for many months.

Prune any dead branches and unproductive shoots to encourage fresh new grow. A light tip prune will also be beneficial. Fertilise plants before and during flowering with Searles Fruit & Citrus Food to encourage more fruit.


Netting: When berries are in season, they are irresistibly juicy and a must to pick, but beware of the birds. Neighbourhood poultry knows when is the right time to pick them as well. Net fruiting bushes with bird and bat-friendly netting are available from good garden and produce centres.
