In this Home & Garden video tutorial you will learn how to prune & clean a Japanese black pine bonsai for spring. First you got to prune off the branches that you don't want and allow only the branches that you want in order to design the tree. After about a year of pruning off the branches cut off the studs created by the left over branches so that the area is flush with the rest of the trunk. Then cut off any dry stubs around the foliage. Next cut off the foliage that is growing out of the shape of the tree. One point to remember is don't cut back to bare wood, leave some greenery. You can watch the video for further instructions.
