So many variations and variables to this question Rick ? what area of Australia do you live in ? Without understanding any of that the best advice I can offer with little information here is, autos like deep pots - this is so there tap root can just power the deeper the pot is more crucial for success then the diameter of the pot autos like sun- sounds obvious but if your auto can receive maximum daylight direct sun the better your success will be autos like light loose soil- this is a major one in my opinion, if it’s outdoors and not in pots try to dig your holes deeper the better (800 deep) and about min450 diameter, if you can, a mixture of perlite, vermiculite, worm castings, coco, and premium grade Seed raising raising mix ( won’t go into ratios but the lighter the soil mix for the tap root and roots to go mad the better) - if it’s natural dense soil you may struggle with yield but again if you get the depth for the roots and potential for a clay breaker you may get a yield of some weight autos like fertilisers- go go juice , seasol are you friend , then some sort of rose slow release pellets during flower Autos like water and sun water and sun water and sun good luck hope this little bit of info helps in some way
