The various Nichiren sects are all branches of one sect. New branches are forming all the time and some of the new branches will become major trunk sized branches while others will remain small and twig-like. Some of the major branches are diseased and need to be cut off at their base or they will kill the trunk and roots. Other less severely diseased branches should be judiciously pruned. If the tree is cared for properly, all healthy branches, whether large or small, will form buds and flower.
