The following are the best management practices for vegetable growing:

Different vegetables mature at different days, but the best time to harvest vegetables is when they are fully matured or when they have attained there physiological maturity.

The best answer to this question is planting frost tolerant, cool season crops that can withstand harsh cold weather e.g. broccoli, cabbage, Cauliflower, lettuce etc. But you can artificially increase temperature in winter by the use of heaters in the greenhouse or artificial lighting in the field that produces heat. Traditionally farmers would fence the edge of the garden to help keep plants off colds. The use of Products like Vapour guard can also help a great deal.
