Grapefruit dropped to a $3.91/kg seven-day mean this week. That’s down 30.1% from the 23-day baseline of $5.59/kg. On a 5kg bag for the marmalade run, the move saves me about $8.40 against where the shelf sat three weeks ago.
I track these numbers because winter citrus swings hard, and grapefruit is swinging now. The baseline held near $5.59 for most of the month. Then it fell off. A 30% week-on-week drop isn’t a wobble. It’s a glut hitting the shelves, and I’d rather buy into a glut than out of one. The prices tracker is what I use to catch these moves before they reverse.
What the Retailers Are Charging Today
Here’s this week’s Brisbane shelf prices, cheapest first:
- Woolworths: $3.31/kg
- Coles: $4.50/kg
That’s a $1.19 gap on the same fruit, or 36% more at Coles for grapefruit off what’s likely the same picking run. I don’t reward that. If I’m buying, I’m buying the Woolies price. Five kilos at $3.31 is $16.55. The same bag at Coles is $22.50. I know which one I’m carrying to the car.
These are Brisbane numbers, so if you’re in Perth or Hobart your exact dollars will differ. The direction won’t. Citrus gluts run national in winter, so the drop you’re seeing here is the drop you’ll likely see there. You can check the full weekly price movements to see what else is moving in your favour right now.
Planting It Instead of Buying It
Grapefruit earns its space because one mature tree throws more fruit than I can give away. The veggie guide covers citrus across all seven zones if you want the detail, but here’s how I’d plant it across two zones.
Subtropical (Brisbane, northern NSW): This is grapefruit’s happy place. I’d get a grafted Marsh or Ruby into the ground now, in winter, while it’s dormant. Full sun, free-draining soil, and keep it off the frost pockets. Mulch wide, water deep through the first summer. A proper soak, not a sprinkle.
Cool temperate (Melbourne, Tasmania, the tablelands): Grapefruit needs more heat than you’ve got to ripen well outdoors, so I’d grow a dwarf variety in a large pot and wheel it under cover before the first hard frost. It’s slower and the crop is smaller, but a potted dwarf still beats $4.50/kg at the checkout. Pick a north-facing wall that holds afternoon warmth.
Either way, a single tree pays for itself inside two seasons against current shelf prices. Mine cost less than three bags of fruit and it’s been feeding me for years. If you’re not sure what else is worth putting in the ground this month, the plant-now calendar will tell you by postcode.
The only catch is that grapefruit takes its time. Plant it this winter and you’re picking in two to three years. The good news is the tree doesn’t care how patient you are. It just keeps fruiting once it starts.
