If temperatures stay warm well into winter, the tree never starts making abscission cells. That means that the scissor mechanism isn't developed in the leaves. Rather than dropping with a cold snap, they simply hang on the tree until they die.

Why do some leaves stay on trees in winter?
The days get shorter in fall and winter, so there is less sun energy to use. Deciduous trees close up the little holes where the leaves attach so they don't lose moisture (MOYS-chur), or water. ... Because they have more water than their deciduous cousins, their leaves stay green, and stay attached longer.
What does it mean if a tree doesn't drop its leaves?
Abnormal weather patterns during the end of fall and early winter can cause trees to adaption to be stifled. For instance, early winter storms, freezes, or cold weather for the time can prevent winter leaf drop; as well as the alternative of a warmer weather pattern continuing through early winter.
Why are the leaves still on the trees?
If a branch dies suddenly during the growing season, it will retain its leaves and will not drop them in the fall. Certain diseases can also result in trees holding onto their leaves late in the fall. In many cases, this is an indication of a broader health problem.
What trees don't lose their leaves in the winter?
Evergreens do not lose their leaves and remain green year round. These include conifers such as pine, spruce, and cedar trees. Evergreens can add drama to landscapes, especially in winter where they make beautiful backdrops amid a blanket of white snow.
Should I take dead leaves off tree?
Most houseplants can be pruned and cut, however, there are certain kinds that care should be taken with— these include most palms and tree ferns. Dead fronds and leaves can be removed, but these plants never form branches, so the top areas of growth shouldn't be cut off, otherwise it will effectively kill the plant.
Is a tree dead if leaves don't fall off?
If it gets bitterly cold before the leaves naturally drop, the cold can kill the leaves immediately. In this instance, the tree didn't have a chance to develop abscission cells, so the dead leaves stay in place. The leaves will fall eventually, either from the weight of snow or from wind.
What happens when a tree loses all its leaves?
Shedding leaves helps trees to conserve water and energy. As unfavorable weather approaches, hormones in the trees trigger the process of abscission whereby the leaves are actively cut-off of the tree by specialized cells. ... This is one of the reasons why trees turn red, orange, and gold colors during the fall.
How long does it take for leaves to fall off trees?
Leaf Fall Dates in the West: Leaves in the West will change in early or mid-October. In Washington, Oregon and Northern California, you'll see peak leaf color in late October. Denver leaves change the earliest in late September. Leaves will fall about one week later, so anywhere from early to late October.
Should I remove dead leaves from Japanese maple?
There is nothing you need to do for your Japanese maple at this time. If your tree was otherwise healthy, new growth will emerge in the spring and the old brown leaves will drop off eventually.
What tree holds its leaves all winter?
Trees that exhibit marcescence are known as "everciduous". Several trees normally have marcescent leaves such as oak (Quercus), beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows (Salix).
