Sometimes nature is the main culprit for brown lawns. Droughts, or dry seasons that do not quite reach drought proportions and limited water supplies, can wreak havoc on your lawn. There are some simple steps you can take to help limit the effect that less water will have on your lawn.
Fertilize less to slow the growth of your grass. Cutting back on the nitrogen supply your lawn receives will cause the grass to grow a little slower, and in turn use less water. If you live in an area that has regular or predictable dry seasons you might want to limit or stop fertilizing all together prior to the dry spell.
Mow higher by setting your mower to the high end of the cutting range for your lawn. Grass that grows on the high side develops deeper roots within weeks and can help shade the soil so that it will dry out slower. This simple change can help your lawn withstand drought better, and greener.
Use gray water to water your lawn and garden. Gray water is left over water from washing clothes or taking a bath. Sounds like a great easy idea, but getting the water to the lawn and easily distributed can be quite difficult. If you are going try this, I suggest reading up on the subject and learning from other peoples mistakes and attempts to save yourself some difficulties.
Just let the lawn go. Either cut back on how often you water or stop watering all together. Let nature have its way and go with it. Many grasses can go dormant for two to three weeks and come back when rain returns. If the grass in your lawn is not one of those that bounce back then reseed with a more drought resistant grass after the dry season has ended. If you cannot stand the look of your brown lawn then you can buy lawn paint, a non-toxic paint made specifically for grass. Yes, someone makes this. Ask at your local nursery or lawn and garden center about it.
Reduce the size of your lawn. While this might seem drastic, it can also be a great opportunity. Do you need a storage shed, patio or walkway put in your yard? This is the perfect incentive to go ahead and reduce your watering and mowing needs. You can also plant some ground covers or garden areas with mulch to take up some space normally growing grass. Dealing with the drought could be the perfect motivation to get those projects done.
Forget the whole thing and use Astroturf. Okay, so I do not really suggest this, and if you try it do not expect me to admire it. However, when lawn and water problems seem overwhelming this option might actually sound good. I repeat, not a real suggestion or something I could truly condone, but at least it would be green.
