Here are the top 5 lessons learned.
Water longer and fewer times a week.
I am down to watering my lawn once a week on Sunday. I have obviously increased the time to about 45 minutes on the larger areas like the front and back parts of my lawn to 20 minutes for the sides of my house. By watering longer, the water has been able to get soaked into the ground and has helped maintain enough moisture to combat the heat. Some weeks are hotter that other, but performing this task has helped me overall maintain a very green lawn.
Try to get in a fertilizer application during a cooler week of temperatures
The summer is really hard on yards and grass needs a little boost of nitrogen to help keep it green during the summer. I was able to put some fertilizer on during the first part of July and it has helped maintain a thick lawn for the summer.
Make sure the lawn is not cut too short.
Make sure your lawn is not cut to short. If you do cut the lawn short, you will see more brown spots. I actually tested this theory and where I had cut the lawn shorter, I also saw more weeds because the thickness was not there.
Watch your mowing patterns
Try changing up your mowing patterns each time you mow. It will help keep your lawn from being matted down and it will actually enhance your thicker lawn. I usually change up the patterns on the front and back yard. My side areas are too narrow to create new patterns each time.
Apply your grub control in Late May, Early June time frame
Make sure you add some grub control earlier rather than later, especially if you have seen grubs in the past. You want to kill the eggs right away. In addition, you will also see thicker grass in areas that used to be havens for grubs.
Obviously the weather is always a factor and some summers are hotter than others, but by applying the techniques mentioned above, you should be able to see quite a substantial difference. In addition, it is always a good idea to test the soil if you are having issues with your lawn. Check out the lawn and garden test package.
