Is it possible to grow passionfruit in the Macedon Ranges?

Bill G, Gisborne, Vic

Yes! I have two passionfruit vines growing in my citrus grove and over the past two years they have produced hundreds of fruit. The key is to create a warm microclimate. You’ll need to select (or create) a protected spot to grow the vines – perhaps against a water tank for thermal mass, or under some eaves, against a north facing brick wall. Check out Growing Citrus in a Cool Temperate Climate for more information on the microclimate I’ve created.

Other marginal crops from the subtropics that I’ve successfully grown in my garden in Kyneton include:

  • many varieties of citrus, including finger limes

  • avocados – I’ve already harvested two fruit. This post describes how I did it.

  • macadamias (more on that in my upcoming nut grove update).

I’ve killed a few babacos and pepinos. They seem to be a bit trickier to establish in this climate.

Should I aim to grow indeterminate or determinate tomatoes? I like the idea of a long harvest, but I’m useless at staking and pruning my plants. The bush varieties have been my preferred choice and I think they are determinate?
