Lawn irrigation is vital to maintaining a healthy lawn. How often you irrigate will depend on several factors. These include the type of grass that covers your yard, where you live, the amount of sunlight that your yard receives each day, and soil conditions.
When it comes to lawn irrigation, over-watering is as damaging as not watering enough. When too much water reaches your lawn’s roots, you increase your odds of having to battle lawn disease at some point in the future, breed weeds, spur excessive growth, and draw insects to your yard. And these are just few of the problems that can come about as a result of excessive lawn irrigation.
To avoid crossing the fine line between under-watering and over-watering, keep an eye on your lawn. It will tell you all you need to know. For example, you probably need to look into your lawn irrigation habits if the blades of your grass are curled, has lost its rich green shade, or if it doesn’t bounce back after stress. Stresses include something being driven on it, something setting on it for a little while, or people and animals playing on it.
Research suggest that lawn irrigation should take place when up to half of your lawn appears to be wilting. Of course, if you determine that your lawn needs watering and you know that it will rain soon, there is nothing wrong with letting nature take care of the problem. Otherwise, turn on your sprinklers, running them only before 10:00 am and after 6:00 pm. If you do your lawn irrigation when the sun is the hottest, you’ll only cause further damage to your lawn. The water will act as a magnet, drawing the rays directly to your grass. And the rays won’t stop beating it once the water has evaporated – it will keep on baking what is left of your lawn.
Doing your lawn irrigation only when it needs it will facilitate root growth which in turn keeps your lawn healthy and more resistant in times of drought. You can encourage root growth not only through lawn irrigation, but by mowing high. To determine how high to mow, look into the specific care instructions for the type of grass you have. You will also want to look into exactly how much water should be included in your lawn irrigation routine. This could vary between ½ inch of water to over an inch and will depend as much on your geographic location as on the type of grass you have.
You can easily find out how long it takes to reach your desired lawn irrigation level by setting a container in your yard when you water. If you goal is to water your lawn with one inch of water, you can time how long it takes for the container to accumulate that one inch. If it takes 20 minutes, you know that each time you water, you will want to keep the water going for 20 minutes. Likewise, if it takes an hour, you will want to set your lawn irrigation system up for one hour.
