But you may set up your lawn for a big let down, he warns. By watering on a regular basis, you keep grass actively growing and prevent it from going through its natural preparation for drought periods. If you run into a sudden water restriction, the grass has to go cold turkey. It can really crash in a hurry. If you choose to irrigate, Landschoot recommends watering deeply and infrequently, early in the morning.
Mornings are the best time because conditions usually are still, and evaporation is minimal.
Also, plants can use water more efficiently. Be consistent throughout the summer, he adds. Keep in mind that watering programs can go awry during vacations or during drought restrictions. You don't want to treat for insects if you don't see a significant problem. Bugs such as grubs are common from August to early October.
