This post is the second part in a four part series about watering your lawn and landscape.
How often should you water your lawn? That is a good question, however there is not a simple answer. The simplest answer would be enough water to keep the grass hydrated. But how much is enough?
The biggest factor for that answer is the weather. Is it hot? Cool? Rainy? Dry? Windy? The hotter, drier and/or windier it is, the more water your lawn is going to need. And the reverse is true for cool or rainy weather, the less water your lawn may need.
The soil type that your grass is growing in can change the amount and frequency of water that is needed. Sandy soils do not hold onto water that well, but clay soils do. If the soil can hold onto water, you may be able to go a little bit into a drier spell. With sandy soils, the water will filter through faster, thus needed to replenish the water for the grass more frequently.
The variety of grass can be another variable. Fescues can go longer without water compared to bluegrass. Ryegrasses are in the middle of the two. Some varieties within a species will last longer/stay greener in a drought situation.
Because of all of these factors, there is not a simple answer to how much water your lawn needs. What we recommend is to monitor your lawn, and adjust the amount of water it receives as needed.
