Dying Grass Problem

Lawn or turf problems can occur in small areas or larger patches, or entire lawns can die. Sometimes the problems are due to poor growing conditions or compacted soil, improper lawn care practices or extreme weather conditions. Is your grass dying in certain areas? We call those areas, stress spots. The grass is either dying or dead.

This year in southern Arizona, it didn’t get over a 100 degrees until June. Bermuda grass grows at night in temperatures above 65 degrees and got a start in late April, but didn’t have a good chance to take over because the temperatures during the day weren’t hot enough to get rid of the winter ryegrass. Because the extreme heat was tardy this year, the Bermuda grass blossomed later. The difficult turf transition this year has made it difficult for the rye to burn out and the Bermuda to properly fill in. Resulting in stress spots.

There are two main resons for “stress spots”. One is from the turf transition and the other is from hard pan or compacted soil as a result of inadequate watering or soild conditioning. You could of had a successful transition or never planted winter rye in the fall and the Bermuda grass would have grown in fine. These spots occur usually from inadequate watering. Early detection will solve most of your problems. If you notice the grass turning blue, that is the first clue the water is inadequate.

To help promote Bermuda grass growth, you can do one or more of a few things. Aeration is always good as it allows oxygen into the soil. Sulpher and Gypsum also helps loosen soil and lowers the pH. In the summer months, add ammonium sulfate (21-0-0) fertilizer to your lawn every three to four weeks at a rate of five pounds per thousand square feet.. Be sure to check and adjust as needed all the sprinkler heads for proper coverage. It may require installing a few new replacement sprinkler heads. My favorite trick to obtaining a pro-active lawn is to leave a hose with trickling water on the stress spot and let it soak in really well. Some areas may require an hour while others can take two or three hours of the slow trickle. Yards with mounds or slopes may require some of this extra attention.
