In this lecture Bjorn introduces the second section of this online course, which is the first developmental stage for Bonsai: setting trees up with radially dispersed surface roots (called the Nebari). The standard technique most bonsai experts apply to create these surface roots, is to prune any vertically growing roots when repotting a Bonsai.
Two years after planting a seed (though depending on the tree species) it is time to bare root and cut the tap root off, but make sure to leave enough fine fibrous roots alive. For cuttings, after about a year you can bare root and trim the lower roots, and place it in a separate pot. This is what Bjorn demonstrates in this first lecture.
After about one year you can bare root air layers and investigate the roots, trimming downward growth as well as overly large roots, balancing the radial growth of roots. After this lecture, your teachers will also discuss various other techniques to improve the Nebari of a Bonsai, like using a washer. Lastly, you might also consider grafting roots as a technique to improve the Nebari of your Bonsai. This video is a free preview lecture from our Developing Bonsai from Seed course.
