Question

What is the meaning for 210 frost free days???

Answer 1

Answer:

Frost free days is defined to be the average duration gap between the last frost day of the spring and the first frost day of the autumn season.  

Cotton needs a moderate temperature to grow.

If the temperature drops below zero, the plants will die and hence, no harvesting will be there.

This is why cultivators need to calculate the frost-free days when the temperature will not drop below zero.
