Check out the most current soil maps and see how soil temperatures have not moved over the last few weeks. It is making for a very late spring season in 2014. Have you noticed your grass is fighting to come up. It really has to do with soil ground temperatures.
A number of growers, yard owners and gardeners are taking advantage of the colder temps and are testing their soil to see exactly what they need for soil ammendments. See more in an earlier article this week.
Continue to follow the soil temperatures in your area and think about applying more water if you are in a drier location. Hopefully temps will go up soon.
