I just laid some Tall Millinnium Fescue about 2 weeks ago, and it has developed small areas of Brown patch due to the high moisture and whatever else I didn't catch in the soil. The sod is rooted in most places now, it's still mostly dark green, and it hasn't been cut yet. Overall, it looks great except some dead patches. The Brown Patch spots aren't connecting and getting big yet but I'm afraid of them growing. My concern is whether the grass is too new to put something like Spectracide on it to cure the brown patch. Will this harm newly rooted sod? I've already bought the stuff but I haven't put it down yet.
