I’m seeing early Phytophthora lesions on newly planted laurels at two suburban sites after last week’s 2.5" storm; soil compaction plus daily irrigation looks like the driver. Before we start trenching and swapping emitters, has anyone used on‑site diagnostics (immunostrips or leaf baiting onto PARP plates) to triage which beds get drainage fixes first, and how are you timing irrigation cuts to keep VWC under about 25% without pushing transplant stress?
