Thatching and Spring Seeding
I know that fall is the best time to seed. I took Andy's advice and did some seeding Aug. 15th. Very happy so far.
I know I will have to seed in the spring. What date or season temperature is good to start spring seeding? I know that I will need to use a different Pre-M.
Also I read that fall is best to De-Thatch, is this true?

The best time to dethatch is when you have thatch. Please post a picture of the vertical slice of the soil, thatch and blades of the grass.

Re: Thatching and Spring Seeding
When you have thatch AND the lawn can recover from it. So summer and winter would be bad times to dethatch. But the first is the more important; many who think they have thatch simply have sloughing off blades that are falling to the soil surface and would naturally decay off on their own.
Thatch is a sturdy lignin-heavy layer of interlocking stem, dead stolon, and leaf that acts as protection for the crown. Amounts of up to a quarter inch are actually quite healthy--and I wouldn't mind having a bit of it. However, even with the second-thatchiest grass (bluegrass), I don't have a bit of it. The bacteria, fungi, and worms gobble it all up for breakfast and canvas the neighborhood, searching for slow-moving children.

So many people that I see talking about having thatch in a lawn are not describing true thatch. I had given up trying to educate about the difference. Thanks, MorpheusPA for the posting!

Re: Thatching and Spring Seeding
Yep. I can almost guarantee that you don’t have much thatch growing a northern Mix lawn.
Thatch is generally a concern in KBG lawns (and with warm-season grasses like Zoysia)
