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.

Impossible to diagnose this type of problem by remote control. We
don't even know what kind of grass or where you live. If the spots
have been the same way for months, then it's just dead turf at this
point that needs to be reseeded or replaced. Why it got that way is
another issue. Could be disease, insects, drought, etc.

Did you take a sample of turf to the ext service? A piece where it
transitions from healthy grass to problem grass is what you want. And
you want it to be when the problem is active and the grass is being
affected. At this point, it may not tell much, as you just have dead
grass while the problem causing it could be long gone.

Regarding the drip irrigation, I've never seen this used on a lawn.
If you think it's not getting watered in spots because of that, then
just lift up a few sections of turf with a spade after watering and
take a look. More lawns have died of over watering though, than lack
of it. Grass will just go dormant without water for quite a long time
before it actually dies. On the other hand, disease and fungus thrive
in wet, hot, high nitrogen environments.
