How often should I give my bonsai tree plant food?

Question:

Answers:
you want to give it a slow release formulated for bonsai... since you aren't trying to push it to grow you want a slow release to just sustain the bonsai... i would pick a slow release bonsai fert and follow their recommendations... of course not fertilizing at all in the winter
