text_A: The weather in Southern California is such that the temperature occasionally drops below 54°F in winter, thus, sun-loving crops like pistachios, kiwifruit, avocadoes, strawberries, and tomatoes are not staple crops of the region, and are usually killed off during the winter when it gets cold. Tomatoes are often dried in the sun and a feature of salads and sandwiches grow consistently there in summer only.
text_B: Do crops grown by Farmers in Southern California growing plants that have some origins in tropical like environments die off in Mid winter frequently?
YES.
