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


Begin reducing watering on lawns and perennials. Water only twice a month. Example, the 1st and 3rd weeks if no rainfall occurs.


Slowly exchange warm season herbs with cool season herbs – cilantro, dill, parsley.  Pinch and use daily.


Add 1/4 inch of high quality, well-aged, screened compost to your lawns.
