I have a juniper tree that is looking mostly healthy. Every few weeks however, I seem to lose a few branches which turn yellowish. I lost most of my top canopy due to this. I’m not sure what to do. Currently I prune the branches off just in case it might be a disease and would spread. I think I’m watering OK but I’m very new to all of this . Also I fertilise once every 2 weeks with a diluted fertiliser.
The tree is still developing a lot of new growth. When I got it 2 months ago it was one of the weaker specimen. Could it be that the root system is not yet powerful enough to handle all this and favours new growth instead of old? It’s only occurring to older branches. It’s currently not yet in Bonsai soil. I’m waiting for a more appropriate time to repot.
