I'm a Bonsai Beginner

Hello, I intend to take the Beginners Course. However I have a question. I just bought a 8+ year old Japanese Juniper Bonsai (Juniperus Procumbens nana) , it came with a little care package and some fertilizer. Its in a 8inch pot.

M y question is, what is the best type of fertilizer should I buy for it? Also the package says to water my JJB (Japanese Juniper Bonsai) every morning and evening but in my research and even on here it states to not routine water but learn when the soil is dry then water. I live in New Zealand and we have just come into Spring. My JJB is in a lovely spot with warm sun, not windy.

Thank you in advance for your help

Never water to a routine, water when it needs it, almost dry, most fertiliser is fine, I use Biogold, but you can use almost any.

If you are in the nortern hemisphere now is soon authum and no fertilizer is needed. So wait adding any fertilizer until spring flush.
