No rain today…grasses around me are starting to turn brown and need a drink.  Time to water, but not at dusk. Water early in the am, 7am or so and then about 6pm. Too late and the water has no chance to dry and you are asking for mold or fungus growth…and that is a costly matter to take up. Watering also means…….not to the point of runoff. About one inch a week. Now, to measure this, use coffee cans spaced along your sprinkler path and water until it reaches a depth of 1 inch in the can…..
