I live in Growing Zone 5B. I am in the process of buying 5 acres of land that is flat and level. Very few trees. There are however two Weeping Willows and a Black Walnut on the property. I am thinking about plantiong the following 3-sourwood trees; 2 Silver and 2 Little Leaf Lindens (Basswood); 2 different Cherry Trees; and 2 Northern Catalpa. I will also be throwing in a few apple trees. Can you think of any other trees suited for this Zone which they might enjoy?
