Ginger will grow well where you live in Sydney. I grew it for years in the well draining garden beds in the ground, whilst living both at Badgerys Creek and Kurrajong areas. I now successfully grow it in pots in Canberra. Check out you tube for tips on the right shade, moisture and harvest tips. . I recommend watching 2 videos: one from Mark from north Qld ‘self sufficient me,’ & other one: ginger in a cold climate from Curtis Stone, for some skills. Ginger from the supermarket is not likely to grow if it’s not australian, because it is fumigated for import. Best success will be Organic Australian to get you started Be patient with ginger and do not over water it in winter. I didn’t use sand to mix in Sydney because it held too much moisture, so look into that. Vermiculite and perlite are good options, depending on whether in pots or in beds.
