In australia you'll have to give tree's like beech, acer, oak mainly tree's that don't have a good level of chorolfyl (Smelling Sucks) protection from harmful UV rays.
If you like the hobby and your interested in expanding your collection to say like 30. It would be worth your while to set something like this not sure what you'd call it but i'll describe it:
Make a sturdy frame over your bonsai and cover the top with a white sheet, it can only be white because the colour white filters UV rays, and lets the benaficial light pass through it.. Thefore protecting your bonsai..
If you can't or dont have the room to make something like that. A list of bonsai species that would do well in your climate are: Pines
Junipers
Spruce
Cypress
Larch
Chinese Elm
Hemlock
Hawthorne
Ficus (semi-Shade)
Etc Anything else that likes lots of sun
Bonsai is a relatively a low maintence hobby, unless you own 30+; It invovles styling by wireing branches, fertalizing every week in spring, every two weeks in summer and not in winter. You also have to do a yearly root prune and trees that are in a pre-bonsai state. And a 2-3 years root prune when you have a mature 10 year old bonsai.
I own 15-20 bonsai at the moment and i hope to have double that in a couple of years time.
Bonsai is a great hobby and it quickly becomes a tradition. I hope in the future my kids will take where ive left off when im not around to care for them and then pass it on again the next generation.
If its possible id like to have a chat with a few users about possibly creating a bonsai forum maybe.. PM me if your interested.
Or I could ask admin from this site to make it another hobby forum.. But i think it would be wiser to create a complete new forum because there is just soooooooo much information about the hobby.. Probs equates to fish keeping.
