I was wondering if perhaps you guys could share your prefered slow release fertilizers and why. Also I am concerned with the balance. I have read to feed with low nitrogen to encourage bonsai size and rammification. However I have also read and been told by some bonsai salesman that I should used either a balanced or a high nitro such as 12%.
Until now I have been using 05-10-05 liquid feed to be on the safe side. But I really want to make sure I am feeding them properly. I have several types of bonsai, Juniper, Maple, Boxelder, Mulberry, Fukien Tea. Is it possible to have some balanced feed that I could use on all my trees? I would prefer to only buy one in bulk pellet form. I'm looking at something around these lines: https://www.amazon.com/Nutricote-13-13-13-5lbs/dp/B000OWHM9Q
I look forward to your suggestions / experiences.
