How to keep your grass green in hot summer weather

Now that we are approaching the hottest days of the year, it’s time to make sure the irrigation system is working properly on our grasses. Repair leaks, broken heads, leaning heads and change nozzles if necessary. The solution to hot spots is not just to increase the run times but to fix the problems. Add heads and correct spacing where needed.
If you have not done so already, aerate grass as needed. The core aeration machine pulls plugs to reduce compaction, thus increasing pore space to improve water, nutrients and oxygen movement in the soil. Therefore, you will get better water penetration when water is applied and deeper roots for healthier grasses.
After this is done, set the irrigation controller run time to stop just before the point of run-off. Fertilize your lawn with a slow-release fertilizer. Adding nutrients in small, steady increments reduces excessive growth and maintains an even green appearance. You will most likely need 2 to 3 applications about 10 to 12 weeks apart.
As the summer gets hotter, drier and windier, you may need to add multiple start times to your irrigation system as the grass dries out really fast.
If you follow these steps, you should have a green grass until the cooler weather returns.
