What a crazy spring.....

Wow, what a spring we've had here in Enid, Oklahoma! What I'm referring to is the combination of warm weather and rain that has everything about 3 weeks ahead of schedule. I think this will be fine as long as we do not get a really hard freeze from now on. A hard freeze to me would be anything under twenty five degrees Fahrenheit for longer than two or three hours. If a freeze event like this occurred it would truly be mother nature's way of hitting reset.

We've had a lot of questions about the timing of our spring application and whether it will still be effective since the bermudagrass has began to green up. The answer is no it will not effect the value of putting down a pre-emergent as the crabgrass, sandburs, and other summer weeds have not began to emerge ye. The only thing we have had to change or drop is the use of Round-Up or Glyphosphate in our tank mixes to ensure no harm is done to our customer's bermuda grass. At the same time we are having to up the rate of our broadleaf control products to ensure quick and efficient control of the winter annual weeds even though they are becoming quite mature. Crabgrass and other summer weeds will not begin to emerge until the soil temperatures have reached fifty-five degrees and can stay there consistently for about a week. Generally in Northern Oklahoma this is right around April 15th.

Here is a map of the current soil temperatures at 2 inches below the sod line:

Question...would you recommend regular lawn watering now when the temps are above freezing? If so, how often and how long? Thanks!
