HORTICULTURE UPDATE is designed as a source of information for County Extension Agents and Specialists to utilize in local news releases and as part of their educational programs across Texas, but will also appeal to gardeners and plant-lovers of all kinds, especially those interested in growing plants under the tough conditions of Texas and the Southern United States. Our information is oriented for Texas gardeners and Texas conditions.

Each issue includes a monthly checklist for suggested garden activities along with articles on gardening topics and profiles of plants especially suitable for Texas and the South. Another feature of the publication is information about forthcoming educational opportunities sponsored by Texas Cooperative Extension.

Dr. William C. Welch and Dr. Douglas F. Welsh, both Extension Horticulturists in the Department of Horticultural Sciences at Texas A&M University, share editorial responsibilities for the newsletter. Articles from County Extension Agents (Horticulture), and Specialists in related disciplines are welcome and encouraged.
