Weather stats for July are interesting. Daytime temperature between 2013 and 2014 were only seperated by 2/10 of a degree at 86 degrees. We were almost 3 degrees below normal for the daylight hours. The big difference was the night temperatures which were almost 4.4 degrees below normal and nearly 3 degrees below last year. Cooler than normal night temperatures help our soil temperatures stay a little lower than normal which is a good thing for a sod farmer like me. Root zones stay cooler which allows the plant to continue to grow. Also, soil on the drier side is better than on the wetter side when it comes to soil temperature. Water is a great conductor of heat so the more water the soil has, the more heat it may retain. Of course, that can go against us as well, the drier the soil the more we have to water which is a problem within itself.
