The growing season is defined as:

The growing season is defined as:

• A. The warmest months of the year
• B. The total days of daylight per year
• C. The time from planting to harvest
• D. The number of days between the last killing frost in spring and the first killing frost in the fall

Answer: (D)

Growing season is the period when conditions allow most garden plants to grow outdoors, which is best defined as the time between the last killing frost in spring and the first killing frost in fall. That frost-free window is what truly limits how long plants can actively develop, since frost can damage or kill crops. It’s not simply the warmest months, because warmth can occur outside that window or end before it, and warmth alone doesn’t define how long plants can reliably grow. It also isn’t determined by daylight hours, since long days don’t automatically mean a longer growing period if frost is still a risk. And it isn’t the same as the time from planting to harvest, because different crops have different maturation times and you could plant and harvest at various dates within or beyond the same frost-free interval.
