Title: Tree species for a small yard
Answered by: Guy Thompson
You are wise to be concerned about tree size and possible damage to retaining walls. Crepe myrtle (non-native) and Prunus virginiana (Chokecherry) are good bets. To view a larger number of possible replacement trees check the Texas Tree Selector web site. Native trees are recommended because of their ability to withstand the Texas climate. This site does not give information on root encroachment, but some useful data on that point will be found at a site dealing with street trees. As a general rule, trees will extend at least small roots out to about the outer drip line of the foliage. Additional information on any of the native trees, including images, can be found by typing the common or botanical name into the Lady Bird Johnson Wildflower Center Native Plant Database.
This is certainly not an ideal season for planting trees. You would be advised to wait for cooler weather in the fall or winter. By checking the list of plant suppliers in your neighborhood on the Lady Bird Johnson Wildflower Center web site you should find a source of suitable trees.
