Trees are dormant in Winter and do not have enough energy to make the buds

Eastern Tent Caterpillars eat the the leaves and early buds from many trees, their favorites being wild or ornamental cherry trees and apple trees. Though they do defoliate trees, the trees themselves most often survive.

The first indications of birch miner infestation are small green spots on the leaf surface, usually noticeable in May or June, which develop into ugly brown splotches. A birch leaf miner infestation rarely kills birch trees on its own but it is disfiguring and can weaken a tree. The leaf miner season begins in late April to mid May with eggs laid in slits on the upper surfaces of birch leaves. Of the number of pests which are attracted the birch trees, the bronze birch borer is the most important as it is both lethal and difficult to control. Evidence of borer infestation is a progressive thinning of the crown of the tree beginning at the top. Trees generally die after about two or three years, that is, after two or three infestations by the larvae. If caught early enough, there are insecticides available to prevent new infestations of the borer but these will not kill larvae already active in the tree. Insecticides such as dormant oil control only the egg stage. Trees with advanced crown loss will not benefit from insecticide use and should be removed. The good news is that healthy, well-situated, well-maintained birches are more resistant to the borer. Females prefer to lay eggs in the sunlight and are less attracted to trees whose trunks are shaded. The insects are also attracted to tree wounds and so care should be taken to avoid damaging the bark of trees.Image Courtesy Canadian Forest Service
Trees grow from the top of their trunks, where new growth occurs in the form of buds and branches.
Deciduous tree loose the leaves each fall. They enter a dormant state in the winter months before coming to live with new buds in the spring.
We still tap the trees before leaf buds appear or else the sap won't have a good flavor. Another example, we still go to the sugar maple tree for the best maple syrup.
of course they do both for photosynthesis and for the differentiation to flower and fruit buds.
No, artichokes do not grow on trees. They are actually thistles that are cultivated for their edible flower buds. Artichoke plants grow large, spiky leaves and produce the edible buds at the base of the plant.
Orange trees have to flower first before a fruit can form. If your tree has not flowered, they will not be oranges, as the orange forms from the middle of the flower. If what you think is a bud is growing from the center of a recent flower, then it is a small orange. Oranges first appear there as a small green, hard ball that looks like a tiny orange.
The Rock Ptarmigan eats a wide variety of foods including; Birch and willow buds, catkins, leaves, berries and seeds. The young will also eat insects.
Removing the upper portion of the stem branches leaving three axillary buds to grow is three buded pruning of trees.
