Hey billi, while working on the roots you really need to be removing them tap roots and removing high roots that are not going to be used in the root plain you decide to use. The aim is to develop a root flare from the bottom of the trunk Which is natural looking, powerful and elegant all at the same time. Hope this helps .
Yes, I definitely agree about removing the tap root. I did that before they were planted in the dirt. If you're looking for a nice radial nebari, then I absolutely agree. Thanks for the comment. Much appreciated
