Heaving primarily occurs during which season?

• A. Spring
• B. Winter
• C. Fall
• D. Summer

Answer: (B)

Frost heave happens when water in soil freezes and expands, lifting the soil upward. This is most pronounced in winter, when soils stay cold enough for freezing and the repeated freeze–thaw cycles drive ice lens formation in moist soil. As a result, bulbs and shallow roots can be pushed above their original depth, causing visible heaving and potential damage. While occasional frost can occur in fall or spring, the phenomenon is tied to sustained winter conditions, which is why winter is the season where heaving is most likely. To minimize it, gardeners improve soil drainage, plant bulbs at appropriate depth below the frost line, and use mulch to insulate the soil.
