Evergreen lawns may need water this month during warm, dry spells. Apply .5-1 inch of water per week if there has been no significant rainfall.
Newly seeded evergreen lawns should be watered frequently as they germinate. After two weeks, begin reducing the frequency but increasing the amount of each watering. By 4-6 weeks after seeding, you should be irrigating deeply and infrequently.
As temperatures warm later in the month, shift your watering schedule so that you irrigate during the day when water will evaporate more quickly from leaf blades. Fungal lawn diseases can develop when grass remains moist.
