Bermudagrass is a warm-season grass. It goes dormant and turns brown during mid-fall to protect it against freezing winter temperatures. As spring weather warms the soil, new green growth initiates from the crown and root system of the grass plant. So we typically see some bermudagrass greening up in Tulsa as early as mid to late March, and into early April, especially on south facing slopes, next to streets and buildings, and other hot spots.

However, when the air temperature then gets down to below freezing, such as 28 degrees early Monday morning, then the green grass blade dies, turning yellowish and then brown. It’s similar to turf going dormant in fall with cold temperatures. And it’s similar to a summer drought causing the bermudagrass to first fold their leaves and turn blue-green, then yellow, and finally going dormant brown.

A hard freeze will kill some tender plants. The good news is that I don’t think the freeze hurt most of the “heart and soul” of the bermudagrass plant, which is the crown and root system. We shall see. The green leaves may be toast now, but the plant will initiate new green growth as the weather warms, and the soil moisture is adequate. It’s like starting a baseball game, you get into the top of the 3rd, and the rains come, causing the game to be cancelled. You may have hit a homerun, but doesn’t matter….it does not count, as the game will be re-played from the start at a later date. So our bermudagrass, surprisingly, was off to a fairly green start after a brutal winter, but then came the Tax Day Freeze of 2014 on April 15th. Your lawn will have to start over now before turning lush and green, and it will. It will just take longer now, and you’ll need to be patient.

We need some good warm and even hot weather….can’t control that. The watering can be controlled, so keep your lawn LawnAmerica has the fertilizer need under control. Applying excess fertilizer will not help, and will actually harm the root system. So with time, and our professional fertilizer, your lawn will be fine. Just be patient! The good news is that since your green grass blades are dead, you won't have to mow for another two weeks or so probably! My lawn last week was greening up and growing to the point of needing to mow, but not now thanks to the "Tax Day Freeze" of 2014. It's brown and looking dormant again! Oh well. Now I'll have time to re-plant those tomato plants that the freeze 10 days ago took out. Never a dull moment when your life depends upon growing things in Oklahoma.
