Yes, weeping cherry trees lose leaves winter as part of their normal yearly cycle. Your tree will drop every leaf in fall. By December it stands bare with nothing but cascading branches on display.
The weeping cherry tree deciduous label means it follows the same pattern as maples and oaks. NC State Extension lists these trees as broadleaf types hardy in USDA Zones 5a through 8b. Winters in those zones get cold. Your tree shuts down leaf functions and goes dormant until spring warmth returns.
Dropping leaves is a survival trick, not a sign of trouble. Leaves lose water through their surfaces. Keeping them in freezing weather would damage your tree. By shedding leaves in autumn, the tree saves energy and water for the coldest months ahead.
I've watched the full cycle on my own weeping cherry for years now. The fall color shift starts with gold and yellow tones in October. By mid-November every leaf sits on the ground. Then the bare branches take center stage. I think the tree looks its most dramatic in January when frost lines each branch in white.
The bare form has a beauty that many gardeners miss at first. Those long sweeping branches make a striking shape against winter skies and snow. In early spring, pink or white flowers pop open on bare wood before leaves show up. This bloom-before-leaves trick creates the look that makes these trees famous.
Your tree moves through a clear pattern each year. Late winter brings swelling flower buds on bare wood. Early spring gives you a burst of blossoms for one to two weeks. Green leaves fill in as flowers fade. Summer brings a full canopy with dense shade under the tree. Fall turns the leaves gold before they drop. Winter shows off the branch form again.
Weeping cherry tree winter care keeps your tree safe while it rests. Wrap young trunks with tree wrap to stop sunscald from freeze-thaw cycles. Keep salt spray and road runoff away from the roots. Salt kills soil life and burns root tips. If you live near a salted road, plant your tree at least 20 feet from the pavement.
Don't worry when your weeping cherry drops its leaves each fall. This process protects your tree and sets up next spring's flower show. Use the bare months to check branches for damage and plan your pruning cuts. The winter view gives you a side of your tree that stays hidden behind leaves for seven months of the year.
