I believe that a sassafras tree is a hardwood
Pulp is neither hardwood nor softwood. Hardwood and softwood are classification of wood types. Both hardwood and softwood can be pulped. There are various types of hardwood pulps and softwood pulps.

Sadly you can't. A tree will grow and will be catagorised into it's species (Oak, Radiata Pine, Sassafras). Each of these species is naturally a hardwood or a softwood. It is not possible to turn the tree from one species to another; and from softwood to hardwood. As a side note, if you have an area of wood made from a softwood e.g floor boards, giving them several coats of an oil lacquer (clear varnish) will provide an added strength against immediate dents like high heels.
