About the Texas Poinsettia Producers Guide:

This guide has been prepared to assist commercial poinsettia producers with many of the cultural and economic problems experienced under Texas growing conditions. We recommend that it be used as a supplement to Texas Poinsettia Producers Guide and The Poinsettia Manual, published by Paul Ecke Poinsettias, Encinitas, California. The Poinsettia Manual is perhaps the most comprehensive reference on commercial production currently available. However, some of the information presented is not totally appropriate for Texas growing conditions. The Texas Poinsettia Producers Guide focuses on these areas and presents supplemental information that growers will find useful in coping with our challenging environment.
