The Woodlands was planted under pines on purpose. Those needles migrate into Rain Bird 5000 and Hunter PGP nozzles until the head throws a stream instead of a fan. Village associations notice the brown parkway strip first.
We pull, flush, and re-nozzle on The Woodlands sprinkler repair route instead of selling a new rotor every time. If the turret is scored, then we replace the head. Shade versus sun on the same zone is the other Woodlands classic — we split or re-nozzle so the pine bed stops staying wet enough for fungus.
