Mark A. Peterson is a conservation project coordinator for San Antonio Water System. With more than 30 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


Prepare fall vegetable garden with copious amounts of high quality compost. In September, we plant the broccoli, cauliflower, beans, & chard.


 Apply 1-2 inches of mulch & compost mixture beneath tree canopies, shrubs, rose beds, and perennial beds.


Water once a week with a sprinkler or soaker hose. Run times will vary with the product. Of course, hand watering may be done any time and any day.

 Hours : 8 a. m. – 5 p. m.
