Vegetables are divided into two groups warm season and cool season. Cool season vegetables, like their name implies, thrive when planted so they mature when temperatures are cooler. In Phoenix this means they should be planted at the end of summer or fall.
Cool season veggies can tolerate short term frost, so if the weather dips in January for a short period of time your cool season veggies will be ok.
If it is 40-50 degrees outside cool season vegetables can germinate. They prefer the soil temperature to be around 60 degrees. If the temperature is too warm, cool season plants will have a bitter taste or they will bolt (go to seed too soon).
