Got brown spots hanging out in your lawn?? Your best bet is to try and give those areas some cool-downs during the day if you can - spray them with water on the hottest days. There is a myth out there that watering during the heat of the day will burn the lawn, but it’s for sure just a myth. It rains daily at 1 PM in Florida and there is no mass lawn scorching reported in the news there. Golf courses practice “syringing” on greens for this same reason. Cooling down the lawn during the day in the hottest areas can help.
You will also want to water more… but when we say that, we mean deeper. You don’t need to water more often. Keep the irrigation to every 2-3 days but instead of getting down ½” go up to ¾” of water each time.
The other thing you want to do, especially in the areas that you see struggling, is after you complete a watering cycle, take a shovel and go dig up a spot and see how far down the water is penetrating. It should be getting down at least 4” into the soil. If it’s not, you will want to water even longer - get that water to penetrate because the roots will chase it and stay cooler in the process.
If you have clay that makes it difficult to get that deep, just have patience and keep packing in the carbon. We have the compaction cure that helps drive through that clay but it takes water too. The Compaction Cure, which is a combination of Air-8 and RGS, and water will drive through that hard clay pack in time. If you would like to know how to use the compaction cure, check out this resource: How do I use Greene County's Compaction Cure?
The root stimulants in RGS can help, and Hydretain can help too, but the data you truly need is the actual water penetration. For more information on “how long you should water” visit Allyn's blog post:
Your lawn can also go dormant in a few spots, as a result of what Allyn calls getting "rain drunk" in the spring. For more information on this particular topic, please check out this blog:

Last piece of advice: track your efforts. If you take your watering up, track that in our free app which has a lawn journal. You can download the app today and get started. Take pictures and upload them so you can track how your lawn responds to the added irrigation vs temps. This way you have real data when you go to make more changes later.
