Excellent post!
Buenos Aires
latitude is 34 degrees (S) similar to Cape Town (S) or Adelaide (S) or Osaka (N)
Note however here is not strictly a temperate climate
Humid subtropical climate (Köppen climate classification:
Cfa) Brisbane and a large part of the lower eastern seaboard of the USA are more similar despite being lower latitudes than BsAs
If in the city then also need to adjust for micro-climate effects - heat island etc effects mean frost is hardly a problem but either overheating (shade!) or over shading definitely become challenges for the urban gardener. Wind burn too if living in a concrete canyon.
This is a
helpful website that gives you planting seasons for different vegetables, herbs, flowers etc. in different climates/areas for a number of English speaking areas.
Mind you I think that you can successfully sow/plant with a far greater range/tolerances than is said here - just treat it as a guide!
Suggest you pick a comparable place on the list for the anglo-sphere and interpolate for optimum planting depending on your own particular growing location.
Do you have a garden or contemplating roof top?
Thanks - I've been meaning to look all this up for my own purposes but seeing your posting reminded me! i also need to check the RHS website.
if you are successful then consider participating as a '
guerrilla gardener'
