One crop, a year of prices, and whether it is worth growing.

Click any crop name on /prices/ and you land on the per-veggie detail page, 12-month price history, per-retailer breakdown, a grow-vs-buy ROI estimate for home gardeners, pest warnings, and seed sources.

Buddy the SproutThe grow versus buy figure is an estimate, and the page says how it is worked out.

What’s on the page

Click any crop name on /prices/ and you land on the per-veggie detail page. Example: /prices/broccoli/.

Seven sections stacked top to bottom:

1. Today’s price summary

Today’s average in big numbers, and the date it was collected. The snapshot answer to “what does this cost today?”

Read the wording of that headline, because it is doing real work. “Averaging $7.44/kg” means several shops agreed on the same thing. “Only Aldi prices this, at $12.48/kg” means one shop stocks it and we would rather say so than dress a single price up as an average. And where the crop has more than one variety on the shelves, a line underneath names the one the figure is for, such as “that is for granny smith, the variety the most shops stock”.

Some crops have no per-kilo price anywhere, because the shop only ever prints a price for the item. Those read “Averaging $3.40 per bunch” or “$4.21 per half” instead. That is the shop’s own printed figure and it is never converted to a $/kg, because converting it would mean inventing a weight.

2. Per-retailer breakdown

Woolworths, Coles, Aldi and IGA with today’s price for each, and the product name that price is for. If a shop has no price for the crop today, its row is left out rather than filled with a guess.

A shop that stocks a different variety, or sells it halved when everyone else sells it whole, still gets its row at its own price with its own label. It just sits outside the average, so the headline stays a figure you can match against one shelf. That is why a shop’s own number sometimes differs from the average above it, and it is deliberate.

Every one of these is meant to survive a check. Open the shop’s site, search the product name shown, and the price should be the one we published. Prices do move between our overnight collection and your click, but the product and the figure should line up. If they do not, that is a fault and we want to hear about it.

3. 12-month price chart

Estimated ROI of growing this crop at home in your zone. Uses typical yield per square metre for the crop, today’s shop price, and typical seed cost.

5. Planting guide link

6. Pest section

7. Seed sources

Common Australian places to buy seed for this crop, The Diggers Club, Green Harvest, Eden Seeds, Mr Fothergills, local nurseries, with typical prices.

The chart, what to look at

Spikes

Price jumps over 30% in a short window. Usually a supply disruption. Examples:

  • Broccoli Feb 2026 spiked to $14/kg for 3 weeks, heat damage to Victorian commercial crops
  • Lettuce Dec 2024 peaked near $12/kg, floods in the Lockyer Valley
  • Capsicum perennially spikes in winter, ends of growing regions out of season

Worth knowing for context.

Seasonality

Most crops have an annual rhythm. Tomatoes peak (expensive) June–August (Australian winter), trough (cheap) January–March. Broccoli is opposite, cheap in winter when supply peaks, expensive in summer.

The seasonality pattern tells you when to buy vs grow.

Long drifts

Slow up or down movement over months usually reflects commodity-level changes (fuel, transport, labour costs) rather than local events. Less actionable but useful context.

Grow-vs-buy estimate

The ROI number on each veggie page uses:

  • Typical yield per sqm at home, varies by crop (broccoli ~2 kg/sqm, kale ~3 kg/sqm, tomatoes 5–8 kg/sqm)
  • Today’s shop price, per kilo where there is one
  • Typical seed packet cost

Worked example

“Growing 2 sqm of broccoli in subtropical autumn: expected yield ~4 kg, value at current prices $23.20, seed cost $4.50, net saving $18.70 across a 90-day crop.”

These are estimates, not promises. Your actual yield depends on weather, pests, and how diligent you are. Compare with our demo garden’s real numbers for a reality check.

Seed sources section

At the bottom of each per-veggie page, a list of Australian suppliers typically stocking that crop. Updated when we learn of new sources; email us if you know of one we don’t list.

Five suppliers covered on most crops:

  • The Diggers Club, heirloom, subscription-based, highest quality for most crops
  • Green Harvest, Queensland-based, subtropical specialist
  • Eden Seeds, biodynamic and organic, very large catalogue
  • Mr Fothergills (Bunnings), wide availability, mainstream varieties
  • Yates, supermarket shelves, common varieties only

For less common crops, only 1–3 suppliers may be listed.
