Please see this extension publication for more information on growing guava (fertilization, insects and disease management, etc): http://edis.ifas.ufl.edu/mg045. PLease note that the pesticides mentioned are labeled for Florida; you will need to check with your extension office or read the label on products at your home store for products labeled for TX and fruit trees.
