You can use any type of fertilizer you like :-) The idea of having a specific type of fertilizer for ever single plant species is silly. Very few require anything out of the ordinary.

Since it ls a mango and you're in Canada, I'd assume this is being grown in a container. If so, you really should focus your attentions on a liquid or fully water soluble fert with all necessary trace elements (micronutrients)....something like one of the Dyna Gro products or even the Miracle Gro blue powders.
