Document on establishing trees

Here is a document from the University of Florida on planting and establishing trees.

For trees less than two inches in trunk thickness, they recommend daily watering after planting for 2 weeks.  For trees 2-4 inches, they recommend daily watering for one month.

I'm not sure how to classify my trees, they each have 3 trunks ranging from 1 inch to 1.5 inches.

Also, considering a hot Texas summer, I was thinking daily watering until it cools down.
