problem:
i have 3 incongruous patches of grass on my lawn, just like the one pictured above, they suddenly appeared:
observations:
the patch is much darker green.
the blades of that grass appear wispy/straw-like.
the blades seem consistent in color, with no visible dots or discoloration.
the crowns don't seem blackened or slimy.
there is a ton of dead grass at the crown that hasn't decomposed yet. also my mower does a poor job of mulching.
i looked for liguiles and auricles to see if i could tell whether the grass is a fescue type (skinny) but i can't tell droughty kbg apart from fine fescue from the descriptions on turfid.
blade from light green surrounding grass:
blade from patchy area, with healthy blade in background for comparison:
outside information:
fertilize .5#/K of milo every week.
i apply companion every 3 weeks.
i apply serenade every 3 weeks. i missed the last serenade application.
the patchy area is watered once a week deeply
the patchy area is watered 5x a week shallow, to fallowing the adjacent grass on same zone, it is watered 3x a day for 5 minutes. (30 minutes yields 1/2 of water).
the other parts of the lawn that have these same patches are only watered once a week deeply.
the mowing height is 3inches, done once a week. seems that i'm not violating the 1/3 rule yet, but getting close in some areas.
these patches happened about a month ago, when i reduced the mowing height from 4" to 3". i got scared and hit them with heritage but we also got a week's worth of rain during and following the fungicide application.
thanks in advance
