I have yellow patches of brown turf that never did come back from the
winter. It is not an even patch but spread through the lawn in various
places. Took soil sample to country extension office and they said to cut
back on water. I would do this except my lawn in that particular area is
showing signs of stress with the gray casting going on which tells me it is
not getting enough water. Anyone know what this is. I did put a fungicide
down last week so we'll see about that. We have one of those underground
watering drip systems that do not have the sprinkler heads. We water from
the root up. Could it be my system is getting clogged? It is only 4
summers old.
