Time to get the irrigation working again

Actually, I am not sure if I want to irrigate the grove.  The trees seem to produce quite happily without much supplementary water, so I am really only watering to keep the fruit trees at the end of each row going - I have stone fruit and citrus and figs and mulberries, a persimmon, a pecan, and two pistachios struggling along in our terrible sand.  But in any case, I needed to do a bit of maintenance, so I have started by cleaning all the 5 field filters and the one in the pump shed.  The next step was to go up and down the rows to see if water is coming out of the loops around the trees appropriately.  A quick look around the Mission, in zone one, was rather worrying.  A lot of loops have been cut up by the slasher, and water is pouring out instead of gently dripping.  This means no water makes it down to the ends of the rows where the fruit trees that really need the water are located.  It is going to be a slow job checking and repairing all the loops across all 5 zones.  Best not to think about it and just get on with it.
