I'm currently using a Jobe's fertilizer spike to fertilize my gardenia plant. It is doing okay, but I want to do the BEST for my plant. What should I use?

Hands down, the best types of fertilizers are pharmaceutical grade. They are pure elements crafted in a lab, and filtered through micron filters to remove ANY solid particulate.

They are usually split into a 16 part system or more, though. They must be precisely measured, and only diluted into water. Then they must be pH balanced after.

The best nutrient systems are far from easy to use, since they require knowledge of how much of each element needs to be mixed in at any given time in a plants life. They are also expensive, running around 400 Dollars or so for a full kit that will last a year.

I recommend going with what is feasible, or natural for your area. There are many single or double part systems that are organic and granular, giving you the best of feeding with quality ingredients and storage ability.

Though We do not recommend certain brands, I would say that your best bet would be, either, compost added each year, or organic granular fertilizers geared toward acid loving plants.
