What do you mean by "conditions"? If you need to ask "what conditions are required to grow native peppers?", then you can ask that in the Bushfood Plants section.
Or "Can I grow grevilleas in Hobart?" - that goes into Australian Ornamentals section.
A general question about "My soil is shale/clay, my climate is hot and dry in summer and cold and dry in winter - help!" would probably best go in the Bushfood Plants section because we'd assume you joined this forum because of an interest in native food plants, and that would be your primary consideration in trying to source plants for your region.
If in doubt, however, you can post in The Pub, as others have, and ask the general question.
