In season in September near the major cities
Melbourne — Melbourne's usual pick-your-own belt, the Dandenong Ranges, Yarra Valley and Mornington Peninsula, is still closed for the season in September. Cherries, berries and stone fruit don't start until November, and Victoria's spring picking properly gets underway closer to summer. If you're near Melbourne in September, the honest answer is: not much is open yet — check back from November.
Sydney — Sydney has a genuine spread of things ripening in September. Citrus is in its last month at Watkins Family Farm in Laughtondale on the Hawkesbury. Berrylicious Strawberries in Thirlmere grows year-round under cover but hits its picking peak from September, and Southern Highlands Flower Farm in Penrose opens its ranunculus, anemone and poppy fields from September through October. Between the three, Sydney's picking mix turns over almost completely across the month.
Perth — Perth's Swan Valley strawberry season is properly underway in September. H&N Strawberries in Gnangara opens its rows for the new season this month, while Swan Valley Sisters in Henley Brook is picking its last citrus of the year alongside the strawberries starting elsewhere. Up in the Perth Hills, Carmel Cherry Farm in Carmel has loquats ready from September, well before its cherries later in the year.
Brisbane — Brisbane's strawberry season is in full swing in September. Chambers Flat Strawberry Farm, south of the city, has its pick-your-own rows open, and Oasis Berries in Caboolture times its picking to the local Strawberry Festival across September and October. North at Stanmore near Woodford, Curlew Ridge Flower Farm keeps its cut-flower fields open through spring for anyone wanting blooms rather than fruit.
Early September vs late September
The picking mix turns over noticeably across September. Early in the month, the last of the season's citrus is still going — Watkins Family Farm's citrus in the Hawkesbury and Swan Valley Sisters's oranges, lemons and mandarins in the Swan Valley both typically run through to the end of the month, while new-season strawberries are only just getting underway, with H&N Strawberries in Gnangara starting its Swan Valley season and the Hawkesbury and Bilpin strawberry farms restarting after winter. By late September, citrus has largely finished for the year in most regions, strawberries are properly underway, and the first spring flowers are opening, including ranunculus and anemones at Southern Highlands Flower Farm and lavender in the Adelaide Hills and Illawarra. It's a genuine handover month — pack for both citrus and strawberries if you're picking early, and expect flowers and berries to dominate by the back half.
