The fresh, cool and often sunny days that Houston residents are blessed with provide ample opportunities to get a jump start on landscaping and lawn care. One Source Residential Services would encourage you to add pruning to your outdoor project list. The summer is a more ideal time for plant shaping, though a too aggressive approach with the clippers can lead to die back.
As a general principle, pruning during the cooler period of the year places less stress on the shrubs. Roses and crape myrtles are excellent candidates for early season pruning. For flowering shrubs like azaleas and hawthorns wait further into the year as temperatures rise. It is important that you rely upon skilled landscapers, careless cutting can lead to unsightliness or even plant loss.
