Your lawn is one of the most important parts of your home. It has a big impact on how your neighbors and guests view your property, how well you enjoy it, and more. Keeping it lush and green is important, and a big part of that is figuring out just how often and how much to water the lawn. There are plenty of variables that come into play, and sometimes getting an exact answer isn’t easy to do. But there are a few guidelines that will help you figure out just what the right amount of water is.
For starters, you need to understand that over watering is just as bad for your lawn as under-watering it is. Too much water can cause fungus or disease to set in on your grass and could kill it just as fast as a long period of dry weather. With that in mind, you need to remember to never water too much.
Simply put, there is no simple answer to this question. The key to figuring out how much to water your lawn is really to determine the different signs that your lawn needs water and then adjust your watering plan based on that. Look for wilting on the blades of grass, or for a blue-gray tint that could set in on your lawn. If you see those signs, or yellowing grass, you certainly need to water it.

The general rule of thumb is that your lawn needs 1 to 2 inches of water per week, and that the water needs to reach a depth of about 6 inches. Start by setting out either a rain gauge or some kind of container to catch water – a tuna can is perfect for this. Turn on your sprinklers and let them run for about a half hour. Then, measure your water amount. You’re looking for about half an inch of water. Then check the depth with a probe or screwdriver. If it plunges into the lawn easily, you’re done with your watering. If not, you may need to continue up to one solid inch.
Different types of grass require different amounts, and you’ll want to look into exactly what your species requires. Also try to avoid standing pools of water or large streams of runoff. This is a sign that you need to switch off the sprinklers and let the water soak into the ground for a while.…
