Why timing varies locally

Adelaide is not one uniform growing environment. This page uses the mapped Adelaide & Mediterranean SA profile, while a nearby locality may resolve differently. Frost pockets, shade, soil, aspect and the variety you grow can all change what is sensible in a particular garden. Treat these dates as a prompt to look at your garden, not a rigid instruction.
