Advice on overseed timeline in Raleigh (still blazing hot!)

Post by redcoat » August 25th, 2020, 10:35 pm

Given the blazing hot temperatures that seem to run deep into September here in the Raleigh area (and the hurricanes / storms that can decimate seed), I'd love some advice on when is typically the optimum time to lay seed down around here?

I believe it's based on soil temp, but what is that temp and what does that correlate to typically in air temps?

For those in the area, when do you typically aim for?

Thanks!

Roughly 45 ish days out from when your soil temps will average 50F.

There’s quite a few soil temp websites out there like green cast.

Keep in mind, fifty degrees and dropping is the last tick on the clock. If a seed hasn't germinated at that point, it probably won't. And bluegrasses need a rock bottom minimum of 25 days...at the warm end of the spectrum.

I'm not so sure the Eastern Seaboard is a great place for renovations this year due to the hyperkinetic Atlantic this year, not to mention the incredibly unstable weather even I've been experiencing up here in relatively-safe PA. Of course I'd decide to grow desert rose this year. I've carted 15 small pots in and out and in and out more often than I can count.

No, not a good time to overseed in Raleigh now. Look at mid to late September. I've had great success into early October, but mid to late September is optimal.
