In summer, lawns need approximately 1" of irrigation per week to stay green and healthy! Even if you plan to let your lawn go dormant, water about once a month to keep it from dying back completely.

When mowing, remember that the height of the grass generally equals the depth of the roots, so keeping grass a little longer helps build a strong support system. Set your mower to medium height to avoid cutting off more than 30% at a time.

See our Lawn Calendar for more monthly tips to keep your lawn lush and healthy.
