Bonsai PruningBonsai Pruning on the apex is required while leaf plus are still very young. It makes the primary and secondary branches more healthy. Pruning twice or trice on the top and once on the first and secondary branches will produce a bigger primary branch. With the limited soil and space, the leaf plus will start on the apex and will not produce good leaf plus on the bottom branches.Note that the primary branch should be bigger than the secondary, the tertiary and fourth branches.
