Spinach Season

Spinach, silverbeet and kale are available year-round in Australia, with peak supply from autumn through winter. All three are cool-season leafy greens that thrive when temperatures drop and tend to bolt or turn bitter in the heat of summer. The category covers three botanically distinct vegetables that often get lumped together on market stalls and in bagged salad blends. English spinach (Spinacia oleracea), silverbeet or Swiss chard (Beta vulgaris), and kale (Brassica oleracea) all behave differently in the kitchen and on the shelf. You'll find them at their best between May and September.

Spinach, Silverbeet & Kale is in season year-round in Australia, with peak supply in summer.

English spinach goes from seed to harvest in as little as 30 days under cool conditions. Baby leaf is cut at 25–35 days and bunched spinach takes a few weeks longer. According to Horticulture Australia VG05068, the best-quality crops come from plantings where daily maximum temperatures stay below 23°C. Above that, leaves grow too fast, reducing shelf life and quality significantly. Silverbeet is a slower, bigger plant that handles a wider temperature range and can keep producing from the same rootstock for months if outer leaves are progressively harvested. Rainbow chard is the coloured-stemmed selection of the same species. Kale takes two to three months from transplanting to first cut, with established plants producing through an entire winter. Its brassica-family connections mean it does best in the same cool-season window as broccoli and Brussels sprouts.

According to the ABS 2024/25 data, Victoria dominates at 45.1% of national output, mostly from east Gippsland (particularly Boisdale) and the market-garden areas around Melbourne. Queensland is second at 31.5%, with Bundaberg and the Lockyer Valley providing the warm-season complement to Victoria's cool-season production. NSW (12.7%, centred on Camden and Hawkesbury), WA (5.3%), Tasmania (4.1%) and SA (1.4%) round out the remainder. Victorian growers plant from August and harvest through to May. Queensland operations take over through the hotter months, and commercial baby spinach businesses typically run two growing sites on exactly this model to guarantee 12-month supply.

The ABS groups English spinach, silverbeet and kale as one category. Combined production was 6,737 tonnes worth $24.6 million at farm gate in 2024/25, down from a peak of around 7,200 tonnes in 2016/17 though rising in value, a shift toward premium bagged formats. Exports have grown from 129 tonnes to 506 tonnes over the past decade. Baby spinach leads the fresh-cut salad aisle at around 50% of the bagged salad category by volume, per industry estimates cited by ABC News (2016). Kale peaked during the mid-2010s and has since settled to roughly 2–3% of the bagged category. A FSANZ 2025 standard now sets minimum food safety requirements for leafy vegetable growers and processors across the full production chain. NSW adopted it from February 2026, with FSANZ estimating the annual cost of illness from leafy vegetables, melons and berries at $20.8 million nationally.
