Watering restrictions are enforced between May 15 and Sept. 15 each year. During this time, watering of yards is not allowed between the hours of 10 a.m. and 5 p.m…
The city recommends using alternative grass types such as fescues, wheat grasses, and blue grama rather than Kentucky bluegrass. They require less water and are easier to maintain. Your local garden center can give you more information on the best grass for your property.
