Check Soil Moisture to Determine Watering Time
After an extended warm, dry period (dry soil is the key) set up your sprinkler and set a timer for 30 minutes. Then turn off the water and check the soil for moisture depth. Do this by pushing a shovel into the lawn and tipping it forward to expose the soil. See how deep the water has penetrated. Moist soil will be darker. Your goal is to run the sprinkler until the water penetrates 3 to 4 in. into the soil.
If the water has not penetrated far enough, restart the watering and continue to keep track of the time. Check again in another 15 minutes. With trial and error, you'll eventually arrive at the optimal length of time to water for your soil type and water pressure.
Add a Remote Hose Connection for Easier Watering
If you're constantly dragging long lengths of hose from the house to the far corners of your yard, consider adding a remote faucet instead. Depending on how much time and expense you want to put into it, this can be as simple as a length of garden hose connected to a fence with pipe straps, as shown here, or an underground pipe complete with a vacuum breaker at the house.
