I'm not exactly a full beginner because I've been studying and practicing my bonsai techniques for about 4 years now but ive always been confused as how to fertilize my trees. I have a juniper, 2 elms, japanese maple, trident maple, pond cypress, hemlock, and a japanese white pine, most are still in training. I live in New Jersey (zone 5) and I was looking for help on fertilizing my different bonsai. The only fertilizer ive really heard of is miracle grow. All the other technical terms are confusing to me. I really appreciate the help.
