Dry Hay Patches in Wet Weather: Red Thread, Not Fertilizer Burn

Northeast, lots of rain. Burnt-looking patches. Fertilizer company applied, rain within 5 hrs. They say red thread; I fear burn. Who's right?

Rain After Fertilizer = Good, Not Burn

Water moves fertilizer to roots. Burn requires fertilizer on dry blades + no water. Rain prevents burn.

Apply 0.5 lb N/1,000 sq ft. Mow regularly. It'll grow out.

Company is right. Red thread, not burn. Feed it, don't fear it.
