Heathmont in the eastern suburbs of Melbourne. We get about 800 mm of rain per year. The average temp in winter is 14/6 degrees max/min. The average temp in summer is 27/14 degrees max/min. Some days get up to 40 degrees in summer, and we get about 5 days of frost per year. The soil type is heavy clay and in winter it is perpetually soggy and wet.

I'm just a backyard gardener, on and off for 10 years.

My main hobby is growing edibles.

The way the dragon fruit grow on a succulent, and the flowers that only open at night make them very intriguing. 

I am a beginner, and have only just started growing them.

I obtained some cuttings 6 months ago, at the start of Melbourne winter. After rooting them on a heat mat, I planted them in pots and kept them indoors next to a sunny window, and they are all taking off now that it is spring.

So far I've only had the chance to try the generic white and red varieties, and the red one tasted sweeter.

Early days for me, so I haven't got any tips yet!

For rooting the cuttings, I immersed the bases in water. After 2 weeks they failed to root because it was still too cold even indoors. I then placed a seedling heat mat underneath them, and voila, they sprouted roots very quickly. So it seems like they prefer temperatures >24 degrees to grow roots. On some cuttings I exposed the cambium layer using a V-shaped cut, which improved the rate of root growth.

This technique was learned from YouTube

I am planning to use diluted worm juice.

11 cuttings of different varieties. I want to see which ones do best in the extreme summers and winters that Melbourne has.
