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


Plant cool season herbs like cilantro, parsley, thyme and chives and vegetables like spinach and Swiss chard


 Use your leaves as a mulch & compost mixture beneath tree & shrubs, rose beds, and perennial beds.


If you have an irrigation system, reduce run times by 50% or run manually. If you water by sprinkler or by hand, water once a month.
