While winter-dormant St. Augustine lawns have yellowed, something is going on under the soil. Winter weeds are beginning to germinate. And a lot of weeds
The statistics are pretty clear: October receives an average of 5.46 inches per month; November, 4.76; December, 4.09; January, 4.22; February, 3.18, and March, 3.03. That is more than enough water to satisfy the needs of lawns. Even most landscape plants can thrive on that much water, unless they are native to tropical rainforests (which would be most out of place in The Woodlands).
Fifty to 75 percent of all drinking water used in municipalities goes to watering lawns and gardens. In dry summer months that can increase to 80 percent or more. The amount wasted can be enormous. As population grows, more and more water is being drawn out of underground aquifers more quickly than the aquifers can recharge. Above ground reservoirs also become stressed.
