What is the best fertilizer for bonsai plants?

I am learning to do bonsai and I like to know what fertilizer I should use to keep them healthy like those that are on sale at plant stores.|||Most types of slow release fertiliser that release over 9-12 months is fine. Just make sure not to high in nitrogen, otherwise you may get to much growth. Depending on what you are growing, make sure you keep the water up as they can drink quite a bit. Good luck.|||Have any dogs and some aspirin?|||Weak solution of miracle gro. Half strength. Bonsai should be misted and llightly watered every day. good luck|||Choose an indoor fetilizer with low numbers or use at 1/2 strength, as you do not really want to promte growth - just good health. Most growers use 20-20-20 diluted in their automatic watering systems.
