Dormant Evergreens?
"But my plant is an evergreen; it doesn't drop its leaves so it's not going dormant." Au contraire, mon ami, the fact that it is an evergreen plant makes the dormant period even more crucial.

This article was originally a post to the Internet Bonsai Club Mail List. It has been edited slightly to make it more readable in this context.
Dormant period represent the period when little or no growth occurs; usually late autumn and throughout the winter months.
Dormant deciduous trees have no leaves and do not need light until they begin growing again. Dormant evergreens do not need light as long as the temperature does not rise above 40 degrees F for very long.
Stage One: Dormant Buds.
When the buds are dormant, the roots are also dormant. During this time the tree can be lifted from the ground or its current pot, bare rooted if necessary and repotted.
Trees that are dormant or sick should not be fed as they will not consume the same level of Nitrogen and salt levels in the soil can build up if care is not taken.
In late spring dormant buds set from the previous summer begin to swell and elongate. These new elongated areas are called candles. (Figures 2, 3). As the weeks go by the candles continue their elongation and also harden off new needles.
Dormant - the period of the year when little or no growth occurs; usually late autumn and throughout the winter months.

Winter is when plants lay dormant. Plants store the nutrition produced in the
previous summer in their bodies and enter dormancy in this state. Generally
speaking, nothing but watering is necessary during this period. If your bonsai ...
Deciduous trees can only be transplanted when dormant, usually in June or July (in Southern Hemisphere), while all evergreens and conifers can be moved very easily at any time of the year.
When a tree is dormant, root pruning can be much more severe.
WINTERING: Most trees (especially sub-tropical and hardy varieties) need to be dormant 2000+ hours to retain they're vigor. I recommend that you read up on your tree to learn it's specific wintering needs ...
While It is true that they become semi-dormant during the blooming time, their recovery and resumption of growth Is severely retarded by the disturbance and trimming of roots at that time.
Winter - (top) Summer Bonsai are in their dormant stage. They require less watering because of colder weather and rainy days, however if weather is warm, check your plants daily. No fertilizing or transplanting this time of year.
Deciduous shrubs and woody perennials need a cold, dormant period in the winter, just as if they were growing outdoors.
I know that it is supposed to "go dormant" during the winter. And I can kind of understand that but I don't really know how to let it do that, ...
The winter dormant period is essential to the general good health of a bonsai. In northern climates winter protection from freeze-drying winds is necessary. Trees should be kept in anunheated area.
During the winter, your Bonsai is dormant and the tree "rests" for the Spring. Junipers, of course, are evergreens and don't lose their leaves like a deciduous tree, but they go dormant just the same.
Clip to shape at any time, however, large branches should be cut during the dormant season when sap is down to prevent bleeding. If you must cut a larger branch during the growing season, cut paste should be applied to the cut.
These are mostly deciduous and evergreen trees and shrubs from cool temperate climates, which have a definite dormant season.
During the early winter dormant period, the tree's ability to heal any pruning wounds is greatly diminished. Pruning should be avoided to prevent excessive die back.
Ten percent of the world's active volcanoes-forty in the early 1990s (another 148 were dormant)-are found in Japan, which lies in a zone of extreme crustal instability.
The best time to repot a tree is at the end of the dormant season, just before the buds begins to swell. Even through there is no dormant season as such, the growth slows down in winter and surges again as the days lengthen in spring.
After two hard freezes the plants are completely dormant. However, based on my experience it is beneficial to start doing your evergreen cuttings earlier than that.
Even though your Bonsai tree will remain dormant during the winter period it's still vital not to let your Bonsai tree dry out, so regular watering is essential.
Some species may exhibit growth patterns regulated by changes in temperature, photoperiod, or water availability, and they will go dormant. The plants may drop their leaves as a signal. As dormancy approaches, gradually decrease the supply of water.
Deciduous - Trees that go dormant and loose their leaves with the onset of cold weather.
Defoliation - Removing all of a tree's leaves to promote smaller leaf growth.
Dormancy - Periods of slowed or suspended growth activity.
It is difficult to tell the age of a plant found in the wild and since they must be collected while dormant, it is also difficult to be sure that the specimen is healthy.
Suckers: Division of suckers in the dormant season.
Grafting: Can be grafted on pomegranate root stock, low success rate.
Notes: The pomegranate sapling are best protected in a warm green house where temperatures above 18C are mantained.
They are deciduous trees meaning that they will lose leaves in fall and be dormant through the winter months. The changing of the trees makes them interesting to watch through the year, but the focus of these trees will always be the color.
Trees need more care during the growing season than in the dormant season. Some species e.g. tropical trees that are often grown indoors require constant care throughout the year.
Since tropical species are protected from frost and have no dormant period, they can be wired at anytime of the year. Yet, due to the vigorous growth of tropical species, the wire can cut in fast, hence, must be checked very often.
In the case of deciduous trees, this is done as the tree is leaving its dormant period, generally around springtime. Bonsai are often repotted while in development, and less often as they become more mature.
As such, your bonsai will require a dormant period each year. This is not such an issue for those who keep their trees outside in a bonsai garden; but for anyone who keeps their bonsai indoors, ...
They go dormant there by providing a wonderful winter silhouette as well as allowing time to prune and collect.
Wiring is best done in autumn or early winter, so that the branches can become accustomed to their new position while the tree is dormant.
They don't thrive below 50F (10C), though will lie dormant and healthy from 50-60F (10C-15C). During this period they will need very little water.
Therefore, the bonsai is still strong enough to leaf out again, but lacks the initial burst of spring energy to produce large leaves and when dormant buds are activated, smaller leaves result.
During The winter the Chinese Elm should be allowed to go dormant, whilst still being protected from the elements.
Germination: Is the process by which a bonsai seeds leaves the dormant state starts into growth, developing roots and shoots.
How controlled: A dormant oil spray applied in winter is said to be effective. These insects can be gently scraped off with a thumb nail or sharp metal instrument.
But I go by the belief that even though the trees are in some what of a dormant state ...
It is also helpful to plant trees in the autumn, when the trees naturally drop seeds into the ground. This is the best time to grow bonsai because it allows the seed to go dormant in the winter, and germinate in the spring, ...
Pot your new tree in well drained bonsai mix and tie in place to prevent it from rocking about and damaging the new root growth. It may also pay to trim back some top growth if the tree is not in a dormant stage.
will flourish if kept indoors; those of similar species to common houseplants like ficus and umbrella plant (schefflera) will thrive indoors, while those based on outdoor shrubs or trees (most confiers, maples, larch, etc) require a cold dormant ...
Fertilize your Bald Cypress tree once a week during the springtime, tapering off to once every two weeks during the late spring and fall (as dormancy approaches). Cease your fertilizing regimen as fall gives way to winter, so your tree can go dormant ...
