The Wax Myrtle has a non invasive root system.
Depending on the mature size of the tree, the distance it is set from the house will control the amount of shade given in a certain area. A tree 50 feet high with a 30-foot spread will cast a shadow equal to the tree height at 3 to 4 p.m. in midsummer. But in winter, the shadow at the same time of day will be 120 feet long. To get the most useful shade on the house at a practical distance, place the tree 15 to 20 feet from the house. Small trees may be planted closer than 15 feet, but large trees should be planted 20 feet or more away from the house.
