why so much brown patch?
2/3 of n from mid sept to late spring. last n app, all of n should be totally released by 5/1
got enough p2o5 in soil?
no muraite of potash
fe and sop help stress
cut lawn weekly at 2.5 to 3" high...never remove more than 1/3 of leaf blade..= usually weekly cutting....shorter hoc and frequent cutting INCREASE turf density
no every other nite watering.....light frequent watering bad......let turf begin to go under stress, then water turf to a 3" depth..... start at sundown, keep cycling all nite, may take more than 1 night to reach 3" depth, THEN TURN OFF the water until turf begins to go under stress again............then start all over.........get healthier turf, and almost NO brown patch
their woill be alot that will disagree with me, but it works
