what determines a growing season, is it temperature or daylight or a combination. i live in a semi tropical country, the winter temperatures average 14c and rarely drop into single figures and there is never ice or frost and the daylight hours do not have the variation of the UK. so what i would like to know is when does a plant know when to flower, fruit and ripen and can i grow all year round.
at the moment i have very mature tomatoes but also some seedlings in pots ready to go into the ground, should i bother. some plants here definitely know seasons like fig trees and grape vines but would a tomato plant know or spring onion or lettuce? as long as they are not too cold and they get enough sunshine would they grow all year?
