Pruning
The best time for pruning branches is between late fall and winter, but is quite resistant to pruning and can be pruned almost throughout the year. ( buy scissors )
The pruning way to use modeling as a technique is to let the branches grow and prune according to the desired direction. Look out in the direction you want for the new branch (left or right) and remove unwanted outbreak. This technique will allow an increase of branching in the chosen direction.
The spruce trees are conifers that heal very well and support the replacement of shoots and the shortening of the trunk by creating a jin in its original apex (far end of the trunk), which also gives them an additional old-age character increases beauty.
The clamps should be made during the time of maximum force when the new shoots are still tender and have grown recently, when just open, with a look that resembles the tail of a fox or a brush. The proper way is to clamp a spruce buds blunt his hand holding a green mass and starting going to pinch the buds pulling with your fingers or tweezers, but never cut with scissors or other tools, making 1 / 3 to 2 / 3. Be careful not to pinch too early to prevent the internodes may be long too, but wait as the new shoots have matured so much that it can not be pinched with the fingers.
If pinched the new growth, especially in congested areas and leaving only that we need for modeling, trees get more branched and compact, with even smaller leaves.
