If you read the September SAWS newsletter that was in with your monthly water bill, you already know this. However, for the rest, SAWS has a garden website containing tips and techniques designed to take the guesswork out of landscaping in the San Antonio area. Go to GardenStyleSA.com. I do not use the Internet much, but I did go to the SAWS website so I could or not recommend it. They must have had me in mind when they designed it. That is, it must have been designed for dummies. Even I could figure it out. The part on plants was very informative.
