Kymtryst I live a fair way away from your local but have visited the very beautiful Geelong Botanic Gardens, in Geelong itself, I would strongly advise you get along to the guided walk taking place on the Sunday 27th Jan 6pm this year. It is celebrating Australian plants at the gardens and you will find many people there to help you with exactly the issues you want answers for. There is a Friends of the Botanic Gardens that would be well worth joining as well.
Botanic Gardens are a greatly underutilised resource in all our cities and larger towns they have in them a wealth of knowledge that the people who work there are only too willing to share with anyone interested. You'd be amazed what little titbits of info you can get about what works and what does not in your area from your Bot Gdns.
