When is leaf fall and dormancy?

• A. Nov-March
• B. Mar-Apr
• C. May-June
• D. March-July

Answer: (A)

Leaf fall and dormancy happen during the vine’s winter rest. In temperate regions, vines shed their leaves in autumn as days shorten and temperatures fall, then enter dormancy to survive the cold. This resting period lasts through winter and into early spring, when buds begin to wake up. In the Northern Hemisphere, that window is roughly November through March, so this range best fits leaf fall and dormancy. The other ranges fall in spring or summer, when vines are actively growing and leaves are still present, so they don’t describe the dormant phase. If you’re thinking about opposite seasons, remember Southern Hemisphere timing would swap to roughly May through August.
