Mark A. Peterson is a conservation project coordinator for San Antonio Water System. With more than 40 years of experience as an urban forester and arborist, Mark is probably the only person you know who actually prunes trees for fun. When not expounding on the benefits of trees and limited lawns, you’re likely to find him hiking San Antonio’s wilderness parks or extolling the virtues of geography and history to his friends.

Timely Tips


Mow weekly at a standardized height and water once a week if no rainfall.


Warm season herbs – basil, oregano, marjoram, and thyme – are at their best.  Pinch and use daily.


Prune trees, roses, and flowering perennials judiciously this time of year. Focus on spent flowers and dead branches.

 Hours : 8 a. m. – 5 p. m.
