Proper watering practices can help reduce the number of weeds in your lawn.
How Much Should I Water and How Often?
There is no one-size-fits-all formula for how much water your lawn needs. It depends on:
- Variety of grass
- Amount of daytime shade
- Root depth
- Soil quality, structure and ph
A soil and site evaluation is necessary to determine how much water your landscape needs. Different areas of your landscape need different moisture levels based on all of these factors.
As a rule of thumb, your lawn needs 1″-1 1/2″ of water per week. If you are unable or unwilling to check the soil on a regular basis, the following rules will help you determine whether to water.
- Know your soil. Clay soils need less water than sandy soils; conversely, sandy soils require more frequent watering than clay soils.
- In general, it is more beneficial to water less often and more deeply. This helps promote deep root growth, which, in turn, allows your grass to go longer between waterings.
- Over watering leads to shallow roots, increased thatch, and an environment that promotes fungal disease and weed growth. Under watering leads to dormancy.
- Shady areas need less water than sunny areas. Likewise, low areas require less water than hills.
- Water in the morning, rather than in the evening or mid-day. This allow more water to penetrate the soil, increasing your watering efficiency, and can help prevent fungal disease.
- Sprinkler systems are wonderful. Unattended sprinkler systems frequently waste water and lead to an unhealthy lawn.
