Late summer and early fall can be particularly hot and dry in this part of the country. Now more than ever, your turf needs thorough and consistent watering.
Your lawn needs water in the root zone, not just at the surface. How long it takes you to water correctly is determined by what kind of soil you have and how long it takes to get it properly saturated. Your soil can be classified as: clay (dense soil with few air spaces and very small, tightly packed soil particles); loam (an open mix with adequate air space for water and nutrients to move); or sandy (very loose and open with little water-holding ability). The type of soil makes a big difference in how often you should water.
