Growing Dahlias In Sydney
Growing dahlias in Sydney? This variety called Astrid Coorabel is a winner!
Dahlias are the floral emblem of Mexico which tells you what sort of heat they thrive in (lots!) and, after a number of years of growing my own dahlias and also watching my brother Fergus go from being a total newbie to a total success in his Sydney courtyard, I’ve put together some of my top tips below.
Although you can grow dahlias in pots (I have before), I have noticed that they seem to grow a lot better in the ground or garden bed. I’ve included all of the important details I’ve learned about growing dahlias in Sydney over the last few years below.

Growing Dahlias In Sydney | 5 Tips
#1 The main thing to know about growing dahlias is that they grow from tubers, not seeds. I’ve put together a list of places across Australia you can buy dahlia tubers here.
#2 Not matter how far and wide you search, most places start only selling dahlia tubers from August/ September. Because they no longer get shipped internationally, you need to be on your game to get them before they sell out! Tubers cost $10-$25 each.
#3 You can buy dahlia plants (where they have already been growing for about a month) if you want to get a head start. The Diggers Club, The Grove Country Gardens Centre and even Bunnings sell these.
#4 Traditionally, dahlia season = summer; however, because Sydney can get summer weather from September, I usually plant my tubers in September. You can plant dahlia tubers anytime up to January in Sydney.
#5 Dahlias take about 3-4 months to grow flowers. Along the way they will need support to keep them upright (from stakes or similar) as the beautiful flowers can get really heavy and start to fall over.
