Mrs. Dim is one of several people in my neighborhood who water their lawns every single day. Since their grass is nice and green and mine tends toward yellow during dry conditions, they of course think that they are right and I am wrong.
They are wrong.
When water is flowing down the street and into the storm drain, they are wasting water. When they water every day, they are training their grass to have shallow roots and to depend upon that daily watering. When they soak their lawns repeatedly, they increase the likelihood of fungus and other diseases in their lawns.
To verify that my opinion is right and theirs is wrong, I did a quick search of lawn watering tips on the internet. Every one of the top hits indicated that Salvageable is right. Among the sites that I read from the first ten hits were Scott, Southern Living, Popular Mechanics, and Green Grass Services. The consensus is that healthy lawns need about an inch of water a week, and that watering twice a week is adequate for a healthy lawn.
Scott recommends one half inch of water twice a week, taking fifteen to thirty minutes, depending upon the watering system. Southern Living says one inch once a week. Popular Mechanics says twice a week, maximum. Green Grass Services says two to three times a week, with a total of 1 to 1 1/2 inches. Several of them recommend using rain gauges or empty tuna cans to measure the water to make sure that the lawn is not getting too much water.
Scott, Southern Living, and Popular Mechanics all say that a healthy lawn can be allowed to go dormant during a dry summer. Scott says the lawn can remain dormant for up to two months. When it rains, the lawn revives. Popular Mechanics notes that the choice of a dormant lawn depends upon use-if people or animals walk or run on the lawn a lot, that could harm the dormant grass.
Experience has shown that my lawn can tolerate a lengthy dormant period. After a decent rain, my grass turns just as green as Mrs. Dim’s grass. Meanwhile she has been watering her lawn every day, cutting and trimming it every five days, working hard to maintain her lawn to her personal standards. Of course she gets up early in the morning to trim and mow her lawn, not caring how much noise she makes while other people are still trying to sleep.
Aside from early morning noise, does the watering of lawns in the neighborhood make any difference in my household? It makes a difference when it takes twenty minutes to fill a sink to wash some dishes. It makes a difference when a shower is nearly impossible due to low water pressure. It makes a difference in the big picture of life, when people like Mrs. Dim waste water because they can, while other people in the country face dire water shortages.
Mrs. Dim is an old dog who will never learn new tricks. It must frustrate her no end when, a day or two after it rains, my grass is as green as hers. It might help if she took the time to check her opinion with research as I have done this morning. Friends, that is not going to happen. J.
