Hi Ryan,
My Itoigawa Juniper has developed bumps along the trunk and primary branches.
I noticed a few of them in October of this year. The number and size of the bumps are increasing.
History; First major styling 2010, into bonsai pot 2013, major trunk bend 2016, with a repot into same pot 2019, minor tweaks in styling yearly in fall.
What is going on? Is this a fungus? Should I paint the bumps with some Zeritol or Hydrogen Peroxide
I believe that to be totally normal for Chinese Junipers.
