What do you call it when trees lose their leaves?

What is it called when trees lose their leaves in winter?
At the end of fall, most deciduous trees lose their leaves for the winter season. In fact, the word deciduous comes from the Latin word decidere, which means to fall down or off.
Why do plants shed their leaves in winter?
The simple answer is this: Leaves fall off trees so that the trees can survive the winter. During that process, the trees lose a lot of water so much water that when winter arrives, the trees are no longer able to get enough water to replace it.
What causes deciduous trees to lose leaves?
Deciduous trees shed their leaves as an active process that evolved to conserve resources and protect the tree from being blown over in the windier winter months. As light levels and temperatures drop, the flow of auxin to the leaves slows and levels of another hormone, ethene, rise.
Why do dead leaves stay on trees?
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 tree keeps its leaves all year?
Broadly speaking, there are two major types of trees: evergreens and deciduous trees. Evergreen trees, like firs and junipers, keep their needles all year round. Many of these trees grow needles or scale-like leaves. Because they don’t lose their needles in the fall, they stay green, thus the name evergreen.
What are the best trees to plant near the house?

Which oak trees hold their leaves the longest?
Evergreen oaks, such as live oak (Q. virginiana and Q. agrifolia), retain their living leaves year-round but do shed their oldest leaves in spring just before young leaves appear.
What tree holds its leaves all winter?
Marcescence is most obvious in deciduous trees that retain leaves through the winter. 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).
What trees do not lose their leaves?

Is it normal for an oak tree to lose leaves in the spring?

Signs of a dying tree: Vertical cracks, cankers (holes where the bark is missing), deadwood (dry brittle wood that easily breaks apart), or no bark are all signs that your tree may be dying, sick, or has damage. As healthy trees age, old bark naturally falls off and is replaced with a new layer of bark.
Why are the leaves falling off my oak tree?
ANSWER: The fact that only one of your oak trees is dropping leaves may mean that the soil around it has been compacted by heavy foot traffic or that soil structure around it is simply different from that under the other tree. If the tree is on a slope water retention may not be adequate.
What does leaves falling early mean?
If your area has experienced drought conditions, it will not be surprising to notice the leaves on your trees beginning to brown out and drop early. This is a protective mechanism for your trees. The tree is trying to conserve water and recover from drought stress.

Live oak is a general term that refers to oak trees that keep their leaves year-round. However, live oaks are messy: their leaves are small and thus hard to rake, and the Spanish moss that they often host drops huge clumps of dead moss every so often. In the spring, the trees flower and cover everything in pollen.
How do you deal with live oak leaves?
