Things you can do to have a green lawn without wasting to much water and staying in compliance with your towns lawn water restrictions.
1) Aerate your soil to allow for circulation of air and moisture.
2) Let the grass grow longer as it decreases the amount of moisture lost from soil.
3) Minimize activity like walking, playing games, etc... on the grass.
4) Least expensive way to a green lawn and save water and money is to use the GRASS PATCH LAWN PAINT/GRASS COLORANT.
During times of drought, lawn water restrictions most commonly result in your grass turning yellow or brown. Thanks to the Grass Patch, you can now have a perfect green lawn all year long, while preserving natural recourses. http://www.grasspatch.net/ or http://www.naturalgreengrasspatch.com/
