Plant Hardiness Zones for Australia

[Steven]

A lot of American bonsai sites refer to Plant Hardiness Zones.
If your interested in knowing which zone you live in check out this site http://www.anbg.gov.au/hort.research/zones.html

That's pretty hard to understand.......plus the map has no details at all.....we might make a better one with major cities mark on it......

thanks for sharing anyway...

[Steven]

Your right vincigu, its not the best map and lacks detail. If you have the time and skills to produce something better, I and the Aussie bonsai community will be indebted to you.

I live in Brisbane and I can't work out if I am a 3 or 4. A better map would be really good!

Australia is made up of tropical in the north to Alpine in the south Dessert in the middle. Take a walk round your suburb look at what is growing there. Relate that to your trees. I have friends that live in the Northern Suburbs of Perth 2kms ( approx ) 1mile apart one is further inland than the other. Winter the guy inland gets frosts the guy nearer to the ocean does not. In the southern suburbs where I live I get frost in winter some times lows about 3% 4% celsius. In summer I get very strong Easterly winds that are very hot 38%% is about the norm after Xmas though to March. What zone map is going to help me ?. Your trees are your best guide watch them for there reaction to condition and apply what is needed shade water humidity so on. I hope this simplistic approach is not too confronting. Pup

Info from a recent post on BonsaiTalk
a description of Heat Zones can be found here
http://www.diggers.com.au/climate.shtm#heat

And use a local Weather station to find out what the actual conditions are like in your area as they vary quite significantly.

On the left goto Climate analysis - Climatology. select the area you are in and scroll down to just below the graph
Very cool

For me this tells me I have 47 days over 30 DegC which puts me in AHS Zone 5.

Check it out for your local Weather Station
ps this is also very useful for working out hown much roof space and tank volume you need to collect enough rain water so we can water our plants in drought
This site is also good for monthly averages. http://www.bom.gov.au/climate/averages/ ... ames.shtml
