The irrigation system is charged and ready to go. This is not because I am worried about the soil moisture levels, but in preparation for aerification next Wednesday. The water is helpful in working the sand into the holes and the turf canopy. The reason that we drain the irrigation over the winter is to prevent the pipes from freezing. We may get freezing temperatures (in fact tonight may get into the mid twenties) but it should not be cold long enough to freeze the pipes.
Speaking of freezing temperatures, the pear orchard between 6 and 8 is just starting to bloom. I took some pictures just in case the flowers get hit hard by tonight's heavy frost. Enjoy them while you can.
