Hello Sally,

No, you should not fertilize a newly planted tree because it needs to establish new roots first. Water and a circle of mulch that does not touch the trunk are best for the tree right now.
Follow this Manual to properly care for your tree- https://trees.umn.edu/sites/trees.umn.edu/files/files/tree_owners_manual_0.pdf

The best things you can do is plant the tree at the correct depth, so that the root collar is at the soil line ( see page 2). If you planted incorrectly, dig it up and replant it now.  Next, mulch and water it correctly (page 11and page13).

Next spring you may lightly fertilize the tree. See this guide-https://extension.unh.edu/resources/files/resource000590_rep612.pdf
