Blueberries are typically seen as cool-climate fruits, but there is a variety with low chill requirements that locals seem to be growing according to https://www.northernstar.com.au/news/blueberries-are-easy-to-grow-gardening/1540173/
A native of North America they have three varieties – highbush, lowbush and rabbiteye. The Southern Highbush is the one commonly grown and sold on the NSW North Coast, producing delicious early season fruit (compared to other blueberries), harvesting from June to February.
It’s a beautiful evergreen bush growing to 1.5 metres with a bright green leaf, and striking pink and white flowers in spring, but is partly deciduous in winter.
Fantastic flavour, fantastic antioxidants. The perfect fruit.
Pick fresh from the plant, cookie in pies, make jams – the sky is your limit.
Planting from an established cutting, it takes around 15 months to begin producing fruit. The berries ripen in stages, so you’ll pick at several times from the one tree.
They like to be well-drained, with good organic mulch, ensuring the water is kept up during summer.
They should be grown in full sun, with protection from strong winds.
Likes having a second plant nearby, for improved fruiting.
They’ll grow well in pots, too.
https://www.groworganic.com/blueberry-misty-each.html suggests having
two varieties, for cross-pollination.
Excellent care instructions at https://joansbolton.wordpress.com/2010/02/03/perfect-blueberries-every-time/ with warnings about careful watering – to avoid the spreading shallow roots from drying out, but also avoiding root rot with good soil care.
Apparently they like coffee grounds, plus any fertiliser designed for azaleas, every 2 months through autumn.
