Best fertilizer to use to grow strong roots of container perennials?

Is there such a thing? Someone mentioned to me recently that they fertilize their container perennials (especially hosta) with one kind of slow release fertilizer and then a different fertilizer starting mid summer. Not sure what they use. But they mentioned that the second slow release fertilizer would be to grow strong roots. That got me to wondering what the different fertilizers are.
